Derek Maetzold: Thank you, Camilla, and good afternoon, everyone. I'm pleased to share that Castle Bioscience has delivered yet another outstanding quarter, continuing our longstanding history of strong execution and performance excellence. Second quarter 2024 revenue grew by 74% to $87 million, and total test report volume grew by 49% to $25,102 compared to the second quarter of 2023. Our strong performance is driven by the team's success in developing a differentiated and innovative portfolio underpinned by robust business fundamentals. Additionally, we believe there is significant room for growth across our portfolio, positioning us well for continued success, and we have a strong balance sheet to support our growth initiatives in alignment with our capital allocation strategy.

Derek: And, we have a strong balance sheet to support our growth initiatives in alignment with our capital allocation strategy.

Derek Maetzold: Our second quarter results highlight our discipline and execution of our strategic growth initiatives, including generating robust clinical evidence and the winning spirit of the entire Castle team. Based on a strong first half performance and confidence in our business, we are raising our full year 2024 revenue guidance to $275 million to $300 million, from the previously reported guidance of $255 to $265 million, reflecting year-over-year growth of somewhere between 25 to 36 percent.

Derek Maetzold: Today, I will walk you through execution and strategy highlights from the second quarter, and then Frank will provide additional financial highlights before we turn to your questions. Starting with our core dermatology business, for Decision DX melanoma, we delivered 9,585 test reports in the second quarter, an 11% year-over-year increase and a 14% sequential increase. As you know, generating robust clinical evidence is a key component of our growth plans, and I'm exceptionally proud of the ongoing data development related to our DecisionDx melanoma test. We believe our significant body of evidence is a key driver for test adoption and also distinguishes our test from the competition, further expanding our leadership position.

Friends: Today, I will walk you through execution and strategy highlights from the second quarter, and then friends will provide additional financial highlights before we turn to your questions.

Derek Maetzold: In fact, during the second quarter, we presented exciting new data at the American Society of Clinical Oncology Annual Meeting, or ASCO, demonstrating how DecisionDx melanoma can identify patients with earlier stage melanoma who have a higher risk of central nervous system, or CNS, metastasis within the first three years post-diagnosis. This study showed that decision DX melanoma is particularly valuable as it can help pinpoint higher-risk patients who may benefit from more frequent imaging surveillance, leading to early detection of CNS metastases and improved patient survival.

Friends: Leading to earlier detection of CNS metastases and improved patient survival.

Derek Maetzold: As background, cutaneous melanoma metastasis to the central nervous system generally has a poor prognosis. However, patients tend to experience better outcomes if CNS metastases are detected and treated early while they are still asymptomatic. Currently, CNS imaging is not routinely recommended for patients with early stage cutaneous melanoma, classified as stage one or two by the American Joint Committee on Cancer, 8th edition.

Friends: Currently, CNS imaging is not routinely recommended for patients with early-stage cutaneous melanoma classified as stage 1 or 2 by the American Joint Committee on Cancer, 8th edition.

Derek Maetzold: Despite this, approximately 14% of patients with stage two melanoma will develop CNS metastasis. Our study demonstrated that patients with a high-risk Class 2b melanoma test result had significantly greater or higher rates of CNS metastases and lower five-year recurrence-free survival compared to those with a low-risk Class 1a or an intermediate risk Class 1b slash 2a test result. Moreover, the study showed that a class 2b decision DX melanoma test result was the only significant predictor of CNS metastasis after multivariate analysis.

Friends: Our study demonstrated that patients with a high-risk class 2b melanoma test result had significantly greater or higher rates of CNS metastases.

Friends: and lower five-year recurrence-free survival compared to those with a low-risk Class 1a or an intermediate-risk Class 1b slash 2a test result.

Friends: Moreover, the study showed that a Class IIb decision-based melanoma test result was the only significant predictor of CNS metastasis under multivariate analysis.

Derek Maetzold: This is to say, this is data that demonstrates the significant clinical value that Decision DX melanoma brings to improving patient care decisions and outcomes. Moving on to our DecisionDx SCC test, we continue to see strong test report volume momentum with 4,277 test reports delivered in the second quarter, an increase of 60% compared to the same period in 2023. DecisionDxSCC continues to be supported by a robust and growing body of evidence, including several publications this year demonstrating the test's clinical and economic value in guiding adjuvant radiation therapy, or ART, decisions in patients with high-risk cutaneous squamous cell carcinoma.

Derek Maetzold: We are particularly excited about a recent study published in the American Society for Radiation Oncology's flagship journal, the International Journal of Radiation Oncology, Biology, and Physics, also known as the Red Journal. This study demonstrated how DecisionDx SCC can identify patients who are eligible for consideration of adjuvant radiation therapy and identify those patients who are unlikely to receive meaningful clinical benefit from ART and consider deferring radiation therapy. On the flip side, the study also showed that our Decision DX SCC test can identify those patients who are expected to receive a significant clinical benefit from ART, with the result being a significant reduction in the likelihood of metastasis. Additionally, we also shared new data supporting the use of our test for patients with cutaneous squamous cell carcinoma tumors on the head and neck.

Speaker Change: Separately, we also share new data supporting the use of our test.

Speaker Change: for patients with cutaneous squamous cell carcinoma tumors on the head and neck. Presented at the American College of Mohs Surgery annual meeting, the data showed DecisionDX SCC's ability to identify high-risk patients, enabling more appropriate surveillance or adjuvant treatments to reduce metastasis risk.

Derek Maetzold: Presented at the American College of Mohs Surgery annual meeting, the data showed DecisionDX-SCC's ability to identify high-risk patients, enabling more appropriate surveillance or adjuvant treatments to reduce metastasis risk. Specifically, DecisionDX-SCC testing before tumor removal significantly improved the prediction accuracy of metastatic events, both alone and when combined with NCCN guidelines, BW8 staging, or AJCC version 8 staging, guiding better Stated differently, this means that our test adds significant accuracy when used with these three staging systems, thus improving treatment pathway decision making. Now, let's turn to our gastroenterology franchise.

Derek Maetzold: In the second quarter of 2024, we delivered 4,782 tissue cipher test reports compared to 1,447 in the same period of 2023 and 3,429 in the first quarter of 2024. This represents 230 percent year-over-year growth and 39 percent sequential growth over the first quarter. We believe this momentum is driven by the test's clinical utility to determine a patient's individual risk of progression from Barrett's esophagus, or BE, to cancer. Supporting our belief, the American Gastroenterological Society, or AGA, recently released new practice guidelines in endoscopic eradication therapy for BE, stating that BE can be treated effectively with endoscopic procedures like ablation, but identifying high-risk patients is crucial.

Catherine Schulte: Hey, guys, thanks for the question. Just first on tissue cipher, a big quarter here for you volumes up almost 40% sequentially. What's driving the growth there? And how should we think about your expectations for sequential volume growth for the rest of the year? And, you know, any change to commercial investments you plan to make there just given the strength you're seeing? Yeah.

Speaker Change: Hey guys, thanks for the questions. Let's disc first on tissue cipher. Big quarter here for you, volumes up almost 40% sequentially. What's driving the growth there and how should we think about your expectations for sequential volume growth for the rest of the year?

Speaker Change: You know, any change to commercial investments you plan to make there, just given the strength you're seeing?

Derek Maetzold: Yeah, it's good to hear your voice, Catherine. This is Derek here.

Speaker Change: Yeah, good to hear your voice Catherine. This is Derek here.

Derek Maetzold: From a tissue cycle perspective, maybe investments first, we had expanded the tissue site for the sales team, I guess it was April 1st, May 1st, early, early, mid-second quarter. And that group of expanded area managers is, I think, just completing final training maybe in the next couple of weeks. And so we would expect them to be effective or fully effective probably in the early fourth quarter or mid-fourth quarter.

Derek: From a Tissue Cypher perspective, maybe I'll investments first, we had expanded the Tissue Cypher sales team, I guess it was April 1st, May 1st.

Derek: Early-Early Mid-Second Quarter and that group of expanded area managers is I think just completing final training maybe in the next couple of weeks.

Derek: And so we would expect them to be effective or fully effective.

Derek Maetzold: So really, really driving, hopefully, additional appropriate use in 2025, maybe obviously some impact now, but more so three or four months out from now going forward. From a demand perspective, I just think this shows us, and maybe everybody, the high clinical need out there for a population that I think we underestimated when we were doing diligence a couple of years ago. There are some data now suggesting that there should be a target market of probably over 400,000 endoscopic biopsies performed per year in people with a definitive diagnosis of Barrett's esophagus disease.

Derek: probably in the early fourth quarter, mid fourth quarter. So really, really driving, hopefully additional appropriate use in 2025, maybe obviously some impact now, but more so.

Derek: Three or four months out from now going forward.

Derek: From a demand perspective, I just think this shows us and maybe everybody the high clinical need out there for a population. I think we underestimated when we were doing diligence a couple of years ago. There are some data now suggesting that there should be a.

Derek: Target market of probably over 400,000.

Derek: Endoscopic biopsies performed per year in people with a definitive diagnosis of Barrett's esophagus disease, so that's by far

Derek Maetzold: So that's by far our largest sort of disease orientation that's tissue-based like that. And I think we're just seeing the efforts of our medical education programs to really educate gastroenterologists regarding the benefit that our test brings to identifying people who have Barrett's esophagus disease so you can have effective interventions at blocking or halting that progression to esophageal cancer and adopting it for appropriate use.

Derek: Our largest sort of disease orientation is tissue-based like that.

Derek: And I think we're just seeing the efforts of our medical education programs to really educate gastroenterologists regarding the

Frank: The benefit that our test brings to identifying people who have Barrett's esophagus disease, you could have effective interventions at blocking or halting that progression to esophageal cancer and adopting it for appropriate use. Frank, do you want to add anything?

Frank Stokes: Frank, do you want to add anything?

Derek Maetzold: Great. And then can we get your response to the MoldeX non-coverage decision for DecisionDx SCC? You know, are there any studies you're running or plan to run to address some of the areas of pushback, be it around performance versus individual NCCN risk categories or generating outcomes data? And then, you know, have you had any follow-up conversations with MoldeX to discuss their vision and next steps there?

Speaker Change: Great. And then, can we get your response to the MoldeX non-coverage decision for DecisionDx SCC? You know, are there any studies you're running or plan to run to address some of the areas of pushback, be it around performance versus individual NCCN risk categories or generating outcomes data? And then, you know, have you had any follow-up conversations with MoldeX to discuss their vision and next steps there?

Derek Maetzold: Yeah, I guess first of all, as you know, or the audience should hopefully know, we had a review completed early 2022 from Novotox. And as of today, we remain covered by Medicare. So the Pymetamol DX LCD doesn't particularly impact our business in the immediate term. That being said, what we did look at when we read through the final LCD was that none of the articles that have been published and that were actually developed as a result of the first of the initial draft LCDs were reviewed or included in this final LCD.

Speaker Change: I guess first of all as you as you know or the audience should hopefully know we had a

Speaker Change: Review completed in early 2022 from Novitas, and as of today, we remain covered by Medicare.

Speaker Change: The Palmetto Moldy X LCD doesn't impact our business in the immediate term. That being said, what we did look at when we read through the final LCD was that none of the articles

Speaker Change: that have been published and that were actually developed as a result of the first.

Speaker Change: of the initial draft LCD were reviewed or included in this final LCD. So we believe there's an opportunity to work in a positive manner with Palmetto to say, hey, there's a really singularly focused benefit of our test to patients with high risk.

Derek Maetzold: So, we believe there's an opportunity to work in a positive manner with Palmetto to say, hey, there's a really singularly focused benefit of our test for patients with high-risk FCC, which is really helping to rule out or rule in adjuvant radiation therapy. So, our intention is to have dialogue with them and understand a path forward so that Medicare patients should we need backup laboratory systems and Phoenix are able to access our FCC test.

Speaker Change: SCC, which is really helping to rule out or rule in adjuvant radiation therapy. So our intention is to have dialogue with them and understand a path forward so that Medicare patients, should we need backup laboratory systems in Phoenix, are able to access our SCC tests.

Mason Carrico: Thank you. Your next question comes from Mason Carrico on Skeeton's

Speaker Change: Thank you. Great, thank you.

Speaker Change: Your next question comes from Mason Carrico with Skidden Sinks.

Mason Carrico: Hey guys, thanks for the questions. Frank or Derek, sorry if I missed this, but could you provide some detail behind what's baked into the guide, specifically from the DecisionDX SEC test standpoint? Is it a full quarter, next quarter only a partial quarter? How should we think about that?

Mason Carrico: Hey, guys.

Mason Carrico: Thanks for the questions. Frank or Derek, sorry if I missed this, but could you provide some detail behind what's baked into the guide?

Mason Carrico: specifically from

Mason Carrico: The Decision DX SEC test standpoint, is it a, are you assuming a full quarter, next quarter only a partial quarter? How should we think about that?

Derek Maetzold: We're assuming that comes out of our numbers for the fourth quarter.

Speaker Change: We're assuming that comes out of our numbers for the fourth quarter.

Mason Carrico: Got it. OK. And, on your broader portfolio, you guys have published a lot of clinical evidence over the past year. Could you just give us your latest thoughts really on how you're thinking about the commercial coverage opportunity, looking at, you know, tissue cipher as well as the melanoma test?

Speaker Change: Got it, okay.

Speaker Change: On your broader portfolio, you guys have published a lot of clinical evidence over the past year, could you just give us your latest thoughts really on how you're thinking about the commercial coverage opportunity, looking at tissue cipher as well as the melanoma test?

Derek Maetzold: I can I would concur with you that the team has done an excellent job of really driving what we see are impactful publications primarily to help establish the clinical outcome benefit of our test and patient care. We have seen, although we don't announce these in a public manner, a number of individual commercial carriers and even some laboratory benefit managers switching from sort of a non-coverage or no statement to positive coverage.

Speaker Change: I would concur with you that the team has done an excellent job of really driving what we see as...

Speaker Change: impactful publications primarily to help

Speaker Change: Establish the clinical outcome benefit of our test in patient care. We have seen, although we don't announce these in a public manner, a number of

Speaker Change: of individual commercial carriers and even some laboratory benefit managers switching from sort of a non-coverage or no statement to positive coverage. Some of those

Derek Maetzold: Some of those policies rolled out, I think, July 1st, that right, Frank, effective date of this year, and we'll see more, I think, early next year. So we are seeing progress there, Mason. We just don't call those out specifically at this point in time, given our life cycle.

Frank: policies rolled out, I think, July 1st. Is that right, Frank, effective date of this year? And we'll see more, I think, early next year. So we are seeing progress there, Mason. We just don't call those out specifically at this point in time, given our life cycle.

Frank Stokes: Yeah, we're making progress, Mason. We would agree with you that there is clearly more than enough evidence published on all of our tests to demonstrate clinical utility and economic savings and economic benefit to the system. So the evidence is certainly sufficient to find coverage. So it's a matter of just continuing to kind of push that rock up the hill.

Frank: [inaudible]

Mason Carrico: Got it.

Mason Carrico: We're making progress, Mason. We would agree with you that there is clearly...

Speaker Change: More than enough evidence published on all of our tests to demonstrate clinical utility and economic savings, economic benefit to the system. So the evidence is certainly sufficient to find coverage. So it's a matter of just continuing to kind of push that rock up the hill.

Mason Carrico: Perfect. Thanks, guys.

Thomas Flaten: Thank you, Mason. We now have Thomas Flaten with Lake Street. You may proceed.

Mason Carrico: Perfect. Thanks, guys.

Mason Carrico: Thank you, Mason. We now have Thomas Flaten with Lake Street. You may proceed. Great.

Thomas Flaten: Great, I appreciate you taking the question. On ID genetics, I know it's still early innings, but are you seeing kind of a physician profile starting to emerge of who's adopting the test and then maybe following on to that? Are there specific patients for whom these doctors are using the test?

Thomas Flatton: Great. I appreciate you taking the questions. On ID genetics, I know it's still early innings, but are you seeing kind of a physician profile starting to emerge of who's adopting the test and then maybe following on to that, are there specific patients for whom these doctors are using the test?

Derek Maetzold: I can comment on that level of detail, Thomas. Our primary call points are a mixture of psychiatrists, obviously, who are interested in helping or having a pharmacogenomic test like ours help improve their therapy decision-making processes, as well as higher volume primary care or first-line clinicians, both physicians and also GPs and PAs who are treating more of an elderly, complex population, and then some long-term care facilities thrown in there And that's primarily because, certainly, those latter two customer groups are wrestling with concomitant drug-drug interactions and, of course, with our report always having provided a drug gene plus a drug and also, of course, an environmental factor reporting structure in the output of the report. It provides those clinicians with a streamlined way to interpret the drug gene combined with the drug and viral bodies.

Speaker Change: I would like to comment on that level of detail, Thomas.

Thomas Flatton: Our primary call points are a mixture of psychiatrists obviously who are interested in helping or in having a pharmacogenomic test like ours help improve their therapy decision-making processes as well as

Speaker Change: higher volume primary care or first line clinicians, both physicians and also MPs and PAs who are treating more of an elderly complex population and then some long-term care facilities thrown in there. And that's primarily because

Speaker Change: Certainly, those latter two customer groups are wrestling with concomitant drug-drug interactions and of course with our report always having provided a drug gene plus a drug-drug and also of course an environmental factor reporting structure in the output of the report.

Speaker Change: It provides those clinicians with a streamlined way to interpret the drug gene combined with drug-drug and viral bodies. Beyond that, I'd be skating on thin ice.

Derek Maetzold: Beyond that, I'd be skating on thin ice.

Thomas Flaten: Got it. And then, flipping to Novitas, have you had any engagement with them following this delay or maybe even leading up to it, and are there precedents we could be looking to to understand how this might play out over the coming months?

Speaker Change: And then flipping to Novitas, have you had any engagement with them following this delay or maybe even leading up to it and are there precedents we could be looking to to understand how this might play out over the coming months?

Derek Maetzold: We haven't. I'm back too far to see about precedents per se. I think it's a reasonably unusual impact.

Speaker Change: We haven't...

Speaker Change: I haven't gone back far to see about precedents per se.

Derek Maetzold: If you look back and you want to kind of look at MoldeX timelines in the past years, like three, four, five years ago, you can see some LCDs that might have gone from draft to final letter, you know, appear to be 370 or 80 days. I don't know if those represented just, um, time for the CMS website to update items or if that was actually a formal request that was granted. So I can give you no flavor on that.

Speaker Change: Impact. If you look back and you want to kind of look at MoldeX timelines in the past years, like three, four, five years ago, you can see some LCDs that might post from draft to final that are, you know, appear to be 370 or 80 days. I don't know if those represented just...

Derek Maetzold: We and others are seeking some input from both Novatofs and CMS to try and understand what this might mean in terms of timing, not necessarily precedent, but any information they give us. We have not heard back any information at this point in time to share.

Speaker Change: Time for the CMS website to update items, or if that was actually a formal request that was granted. So I can give you no...

Speaker Change: We and others are seeking some input from both Novatofs and CMS to try and understand what this might mean in terms of timing, in terms of, not necessarily precedent, but any information they give us. We have heard back no information at this point in time to share.

Thomas Flaten: Got it. I appreciate it. Thank you.

Speaker Change: Got it. Appreciate it. Thank you.

Puneet Souda: Thank you, Thomas. We now have Puneet Souda with Z-Rank Partners.

Speaker Change: Thank you Thomas. We now have Puneet Souda with B-Rank Partners.

Puneet Souda: Yeah, Derek, Frank, thanks for taking my question. So, first one is, you know, you had a beat here, 18 million or so, guide raise is about 27 and a half, and just wondering if, in the third quarter, you are including the FCC coverage, if I heard that correctly. So just wondering, you know, shouldn't the guide raise be more than that to reflect if you are, as Frank said, you will be covered in the fourth quarter as well? So I just want to understand sort of the dynamics of SCC, volume growth, and the ASP that we ought to be thinking about over the next two quarters with respect to the guide.

Juni Tsuta: Yeah, hi, Derek, Frank, thanks for taking that question. So first one is...

Juni Tsuta: You know, you had a beat here, 18 million or so, guide raises about 27 and a half, and just wondering, you know, third quarter, you are including the FCC coverage, if I heard that correctly.

Speaker Change: So, just wondering, you know, shouldn't the guideways be more than that to reflect if you are, if I think Frank said,

Speaker Change: You will be covered in the fourth quarter as well. So I just want to understand sort of the dynamic of SCC volume growth and the ASP that we ought to be thinking about over the next two quarters with respect to the guide.

Derek Maetzold: So our new guide assumes that we don't have SCC coverage in the fourth quarter, and I wouldn't, I wouldn't have any comment or any change to our ASP. We don't, I don't think you'll see a change in ASP from now until then.

Speaker Change: So our new guide assumes that we don't have SCC coverage in the fourth quarter, and I wouldn't have any comment or any change to our ASP. We don't, I don't think you'll see a change in ASP from now then.

Puneet Souda: Okay. And then, you know, Derek sort of stepped back and just looked at the MALDI-X, you know, maintaining their non-coverage decision. Novitas is disclosing an extension now, which is unclear exactly when they will come back and, you know, cover this test. So, you know, the question here is, should we assume, first of all, that there will be no coverage for 2025? I just wanted to clarify that.

Speaker Change: Okay.

Derek: And then, you know, Derek sort of stepping back and just looking at the Maldi-X, you know, maintaining their non-carvers decision.

Speaker Change: Novotaz disclosing an extension now which is unclear exactly when they will come back and you know cover this test

Speaker Change: So, you know, the question here is...

Speaker Change: you know...

Speaker Change: Should we assume, you know, essentially, first of all, should we assume no coverage for 2025? That's, just wanted to clarify that.

Derek Maetzold: And, you know, I do hope that you get coverage here from Novitas, but if that wasn't going to happen, then what are the other avenues? And then, ultimately, how do you bring this test to the commercial population? You know, just help us elaborate on the path forward for this test and the path to getting paid for it.

Speaker Change: You know, I do hope that you get coverage here from Novitas, but if that wasn't going to happen, then what are the other avenues?

Speaker Change: and then ultimately...

Speaker Change: How do you bring this test to the commercial population, you know, just help us elaborate on the path forward for this test and the path for getting paid for this test?

Derek Maetzold: A lot of questions to unpack there, Puneet, to try and be brief and organized here. I think, first of all, we remain a covered test by Medicare, point number 1. Point number 2, in terms of forecasting SCC in your guide going forward, I would, I think, as Frank said, take it out on October 1st going forward just because it's a prudent overhang there, so that would be our recommendation.

Speaker Change: A lot of questions unpacked there, Puneet, to try and be brief and organized here. I think first of all we remain a covered

Speaker Change: test by Medicare. I guess point number one. Point number two in terms of

Speaker Change: Forecasting SCC

Speaker Change: In your guide going forward, I would, I think as Frank said, take it out October 1st going forward, just because it's

Frank: A prudent overhang there. So that would be our recommendation. That's how we're thinking about our business as well.

Derek Maetzold: That's how we're thinking about our business as well. In terms of next steps, there are a number of options one could consider taking with Novotox as well as Palmetto, which would include Reconsideration requests if it was negative, which would include challenges to the LCD, other interactions with CMS, as well as individual Claim appeals. All of those are on the table, and as we see the outcome here, we can pull the trigger on what the appropriate approach should be. I guess that covers questions. I think so.

Frank: in terms of

Frank: Next steps, there are a number of.

Speaker Change: approaches one could consider taking with Novitas as well as Palmetto, which would include reconsideration requests if it was negative, which would include challenges to the LCD.

Speaker Change: other interactions with CMS as well as individual claim appeals. All of those are on the table, and as we see the outcome here, we can pull the triggers on what the appropriate approach should be. I guess that covers the questions. I think so.

Puneet Souda: Okay, maybe just briefly on EBITDA improvement. The improvement was strong in the quarter. Frank, any thoughts on how we should think about that for the rest of the year and 2025? If you could elaborate, thank you.

Speaker Change: Okay, maybe just briefly on ABIDA improvement was strong in the quarter. Frank, any thoughts on how should we think about that for the rest of the year and 2025, if you could elaborate? Thank you.

Frank Stokes: What improvement, Puneet?

Puneet Souda: Just said that Bintar came in strong versus our estimates and just wanted to get a view on the continued ramp there. Obviously, some of it is from SEC getting paid, but just...

Speaker Change: What improvement, Puneet?

Speaker Change: Just that the debt came in strong versus our estimates and just wanted to get a view on continued ramp there. Obviously some of it is from SEC getting paid but just

Frank Stokes: Yeah, we continue to see us grow into the P&L, and we're seeing leverage across the P&L as revenues grow more than expenses, and that obviously drives a better margin. Going forward, what that profile looks like depends on coverage for SCC, among other things. So, as we said before, our long-term guidance, which we've reiterated for 2025, assumes no SCC coverage but still hitting a positive adjusted operating cash flow.

Frank: We continue to see us grow into the P&L, and we're seeing leverage across the P&L as you see revenues growing more than expenses, and that obviously drives a better margin.

Speaker Change: Going forward, what that profile looks like depends on coverage for SCC, among other things. So, as we said before, our long-term guidance, which we've reiterated for 2025, assumes no SCC coverage, but still hitting a positive adjusted operating cash flow.

Kyle Mikson: Your next question comes from Kyle Mixon with Canacord.

Speaker Change: Thank you. Your next question comes from Kyle Mixon with Cancord.

Kyle Mikson: Yeah, guys, thanks for the questions, congrats on the quarter. Yeah, just sticking with SAC. If you, you know, if that remains un-covered by both these MACs here and there's something you can do in the near term for that, what can you do on the dermatologic cancer side of the business to, you know, keep growth and kind of maintain margins as well? Like, could you shift resources to marketing decisions to de-act melanoma, or is there something about the past practices that kind of prevent you from beefing up the melanoma marketing effort?

Kyle Mixon: Yeah, hey guys, thanks for the questions, congrats on the quarter. Yeah, just sticking, going back to SEC, I guess, if you, you know, if that remains non-covered by both these MACs here and there's something you can do the near term for that, what can you do in your dermatologic cancer side of the business to, you know, like, keep growth and kind of maintain margins as well? Like, could you shift resources to marketing decisions you have to melanoma or is there something about the past practices that kind of prevent you from beefing up the melanoma marketing effort?

Derek Maetzold: Excellent question, Kyle, many of our programs today because it's what we're primarily calling on interacting with medically oriented dermatologists who see patients with skin cancer as kind of the same kind of clinician, you might say. I mean, there might be a few less Mohs surgeons who are seeing or applying Mohs surgery to invasive melanoma like it would be to squamous cell carcinoma. So, I think that we feel like we're sized right from a field perspective.

Kyle Mixon: Excellent question, Kyle.

Speaker Change: Many of our programs today because it's a

Speaker Change: What we're primarily calling on, interacting with,

Speaker Change: medically oriented dermatologists who who see patients with skin cancer is kind of the same kind of clinician you might say I mean there might be a few less Mohs surgeons who are

Speaker Change: who are seeing or applying Mohs surgery to invasive melanoma like it would be to squamous cell carcinoma.

Derek Maetzold: There are certainly some other marketing and other educational activities that we would kind of redirect, I guess you would call it, our FCC dermatology spend on marketing and medical education over towards melanoma specifically so that it would hopefully have the intended expectation you have here, which is whether we go ahead and be able to improve upon the sort of market penetration adoption of appropriate patients for the melanoma test. I don't know what that would look like in execution at the end of the day, but certainly we're thinking about the same thing.

Speaker Change: So, I think that we feel like we're sized right from a field force standpoint.

Speaker Change: There are certainly some other marketing and other educational activities that we would

Speaker Change: kind of redirect, I guess you would call it our FCC dermatology spend and marketing and medical education over towards melanoma specifically so that it would have hopefully the intended

Speaker Change: expectation you have here, which is would we go ahead and be able to improve upon the sort of marker penetration adopted of appropriate patients for the melanoma test. I don't know what that would look like execution at the end of the day, but certainly we're thinking about the same things.

Kyle Mikson: Okay, that was great. Thanks, Eric.

Speaker Change: Okay, that was great. Thanks, Derek.

Kyle Mikson: And yeah, maybe just like a two part question. So first, it's really interesting that the kind of tax rate, basically the kind of synergy rate between SEC and Melanoma, is 68% for the first half of the year, which compares to 55% in 1Q. What is that? What benefits have you seen there? And again, as you think about this like flipping possibly, maybe that's in the fourth quarter or something like that.

Speaker Change: Yeah, maybe just like a two-part question. So first is the, um...

Speaker Change: really interesting that the kind of the tax rate basically like the kind of synergy rate between SEC and melanoma is 68% for the first half of the year that compares to 55% in one cue what is that what benefits have you seen there look and again as you think about this like flip possibly maybe that's in fourth quarter or something like that

Kyle Mikson: You know, how does that really kind of give you confidence for 25% growth basically? That's the first part of the question. And just given your second part is going to be about your cash balances, how do you think about M&A going forward? Which side makes sense to bolster that dermatologic side or maybe like this GI side that is super promising? Thanks.

Speaker Change: How does that really give you confidence for 2025 growth, basically? That's the first part of the question. The second part is going to be about your cash balances. How do you think about M&A going forward? Which side makes sense to bolster? That dermatologic side or maybe this GI side that is super promising? Thanks.

Frank Stokes: I'm sure Kyle. So starting with the cash here, I think that we're pleased to have the cash position. We do. It's enabled us to run the company as we think it needs to be run and to cautiously and carefully invest in continued growth. And so those are our first priorities: sales and marketing of our existing products, and then R&D to support those products as well as new products. M&A is further down the list. Obviously, we never say never, but we've got a tremendous opportunity at hand with the products that we currently have available.

Kyle Mixon: I'm sure, Kyle. So,

Kyle Mixon: Starting with the cast here, I think that

Speaker Change: We're pleased to have the cash position we do. It's enabled us to run the company as we think the company needs to be run, and to cautiously and carefully invest in continued growth, and so those are our first priorities is sales and marketing of our existing products.

Speaker Change: and then R&D to support those products as well as new products. M&A is further down the list. Obviously, we never say never, but we've got a tremendous opportunity at hand with the products that we currently have available.

Kyle Mikson: Kyle, what was the first part of your question? That was really our thesis, you know, in developing our SEC test is, you know, having more than one test to sell to the same physician, and there's a balance there. You can only have so many, you can only have conversations about so many things in a physician encounter. So because those tests are largely the same physician base, there's great opportunity and great leverage.

Speaker Change: Kyle, what was the first part of your question?

Kyle Mixon: So that was really our thesis, you know, in developing our SEC test is

Kyle Mixon: having more than one test to sell to the same physician. And there's a balance there. You can only have so many, you can only have conversation about so many things in a physician encounter. So because those tests are largely the same physician base.

Kyle Mixon: There's great opportunity and great leverage.

Kyle Mikson: For a non-medical person like me, it's a pretty simple thesis. You know, each of those tests answers a similar question just for a different group of patients. And so once a physician has been educated on the benefits of a test for melanoma, for example, it's an easy adjacency to say, now you've got these other patients over here, and we have a test that answers the same question with the same clinical utility.

Speaker Change: For a non-medical person like me, it's a pretty simple thesis. You know, each of those tests answers a similar question just for a different group of patients. And so once a physician...

Speaker Change: has been educated on the benefits of a test for melanoma, for example.

Speaker Change: It's an easy adjacency to say now you've got these other patients over here.

Kyle Mikson: So there's great synergy there, and there's powerful leverage between the two. So that was part of our thesis originally. When we set out to develop the FCC test, we heard from clinicians that they had a, And it struck us that those were the same clinicians for whom we were answering a similar question in melanoma, so there's great leverage between the two. Okay, perfect. Thanks.

Speaker Change: And we have a test that answers the same question with the same clinical utility. So there's great, there's great synergy there. And it's a, it's a powerful leverage between the two. So, that was part of our thesis originally when we, when we set out to develop the FCC test, we heard from clinicians that they had a.

Speaker Change: a clinical question that needed to be answered. And it struck us that those were the same clinicians for whom we were answering a similar question in melanoma. So, there's great leverage between the two.

Kyle Mikson: Okay. Perfect. Thanks, guys. I appreciate it.

Speaker Change: Okay. Perfect. Thanks, guys. Appreciate it.

Sunny G. Naran: Thank you. Your next question comes from Sunny G. Naran with Scotiabank. Your line is open.

Speaker Change: Absolutely.

Speaker Change: Thank you. Your next question comes from, who's dialing you now? It's Scotiabank. Your line is open now.

Sunny G. Naran: Hi, thanks for taking the question. Maybe starting with Tissue Cipher, congrats on getting that mentioned in the AGA publication. The same publication talks about forthcoming guidelines on surveillance in Barrett's esophagus, and I was wondering, you know, if you have any insight into kind of the timing for that and whether you guys might be engaged with the AGA, you know, in terms of providing data and things like that.

Speaker Change: Hi, thanks for taking the questions. Maybe starting with Tissue Cipher, congrats on getting that mentioned in the AGA publication. The same publication talks about forthcoming guidelines on surveillance in Barrett's esophagus.

Speaker Change: And was wondering, you know, if you have any insight into kind of the timing for that and whether you guys might be engaged with the AGA, you know, in terms of providing data and things like that.

Derek Maetzold: Yeah, their cadence of guidelines updating is a little opaque, Sanjeev. I would think we're talking a couple of quarters out, at least. And certainly, our teams are working as they should to make sure that appropriate stakeholders are aware of the tissue cipher data and hopefully how to consider it against sort of not using a tissue cipher test. But timing of that, I would think would be a couple of quarters away. But it's a little bit of a more opaque organization than, say, NCC, where you can have a history of updates, and you see where they are. Meetings, updates are coming out, usually at a routine cadence.

Speaker Change: Yeah, their cadence of guidelines update is a little opaque, Sanjeev. I would think we're talking a couple of quarters out at least, and certainly our teams are.

Speaker Change: are working as they should to make sure that appropriate stakeholders are aware of the tissue site for data.

Speaker Change: and hopefully how to consider it against sort of not using a tissue cipher test. But timing of that, I would I would think would be.

Speaker Change: a couple quarters away, but it's a little bit of a more opaque organization than, say, NCCM, where you can have a history of updates and you see where they are. Meetings, updates are coming out usually at a routine cadence.

Sunny G. Naran: Got it. And then maybe following up Catherine's question earlier on the Moldex determination, just kind of curious; it seems like they're pretty positive, you know, in terms of the use of this in the FFCC and patients for adjuvant radiation therapy. And so I was wondering if you're, you know, if you guys have additional studies. You know, what are your strategies in terms of potentially implementing additional studies around that? Are there ways to incorporate or kind of get involved in some of the larger-scale studies that might be underway? Just kind of curious if you could touch on that. Yeah, an excellent question. So

Speaker Change: Got it. And then maybe following up Catherine's question earlier on the Moldex determination, just kind of curious about, it seems like they're pretty positive in terms of the use of...

Speaker Change: You know, what are your strategies in terms of potentially implementing additional studies around that? Are there ways to incorporate, you know, kind of get involved in some of the larger scale studies that might be underway? Just kind of curious if you could touch on that.

Derek Maetzold: Yeah, excellent question. So we're always doing more studies. So how's that for a non-answer, which I don't mean to be cynical to you.

Speaker Change: Excellent question. So,

Speaker Change: We're always doing more studies.

Derek Maetzold: When we first saw this data on ART, I guess about a year, a year and a quarter ago, we certainly said, okay, this is quite interesting. We will end up publishing, if you go back in May, of course, the most, I guess, the best controlled article that we've seen out there evaluating the effectiveness of ART, which is good. And so we have begun additional programs to look at highlighting that, replicating the data essentially. So we expect to see things coming out later this year that would support that study that came out in May of this year by Aaron et al as being confirmed from a performance standpoint.

Speaker Change: How's that for not answering? I don't mean to be cynical to you. When we first saw this data on ART, I guess about a year, year and a quarter ago, we certainly said, okay,

Speaker Change: This is quite interesting. We will end up publishing this in the back of May, of course, at the most.

Speaker Change: I guess the best controlled article.

Speaker Change: that we've seen out there evaluating the

Speaker Change: effectiveness of ART, which is good. And so we began additional programs to look at highlighting that, replicating the data essentially. So we expect to see things coming out later on this year that would support that study that came out in May of this year by Aaron et al as being

Sunny G. Naran: And great. Thank you. Great. Thank you

Speaker Change: And great, thank you. Great, thank you.

Subhu Nambi: We now have Subhu Nambi on Guggenheim. Your line is open.

Speaker Change: We now have Subhu Nandi with Guggenheim. Your line is open.

Subhu Nambi: Hey guys, thank you for taking my question. I don't think this is the case, but I just want to make sure, from a risk perspective, given that Novartis is reviewing, is there any retrospective risk to the revenue from SEC? That's one, and I have a follow-up.

Subhu Nandi: Hey guys, thank you for taking my question. I don't think this is the case, but I just want to make sure, from a risk perspective, given that Novatox is reviewing, is there any retrospective risk to the revenue from SEC?

Speaker Change: That's one, and I have a follow-up.

Derek Maetzold: Couldn't quite hear the question. Retrospective risk to SEC given that it was overdrafted.

Speaker Change: to produce Bank at Risk.

Subhu Nambi: to the revenue from the.

Speaker Change: Good, any other questions? What's your expected risk to SEC given Novotel's... ...to the revenue from the SEC?

Subhu Nambi: Is there a retrospective risk to SDGs? For the revenue. Oh, back to revenue? Novotoff reviewed us back in that first quarter of 2022, included us in a billing article I think in April or May of 22, indicating that we're covered by the test. We bill specifically with our unique PLA code, which we received I think in April or March of 2022. So I don't think that's any kind of realistic expectation. There'd be a clawback when they know exactly what they're paying for.

Speaker Change: Novitas

Speaker Change: reviewed us back in the first quarter of 2022.

Speaker Change: including included us in a billing article I think in April or May of 22

Speaker Change: Indicating that we're a covered test. We bill...

Speaker Change: Specifically with our unique PLA code, which we received, I think, in April or March of 2022, so I don't think that's any kind of a realistic expectation. There would be a clawback when they know exactly what they're paying for.

Derek Maetzold: Got it. That's helpful, Derek. It is good to see this melanoma grow 14% sequentially, and it also alleviates the concern around volume growth moderating. Do you still anticipate growing double-digits until you reach 50% market penetration?

Speaker Change: Got it. That's helpful, Derek. It is good to see melanoma growth 14% sequentially, and it also alleviates the concern around volume growth moderating. Do you still anticipate growing WGET until you reach 60% market penetration?

Subhu Nambi: That was about CM Sibu.

Derek Maetzold: That is decision BX, melanoma, yes.

Speaker Change: That was about CM2?

Frank Stokes: Yeah, so, you know, ever since the IPO, we have had a chart on MD&A that shows the volumes for all of our tests. Obviously, at that point, it was just CM and UM, but, what you can see is with the exception of 2020, which was, if you recall, the year that we all let them convince us that some groups of positions were not essential, and they closed their offices.

Speaker Change: That is Decision DX, melanoma, yes.

Speaker Change: Yeah, so, um...

Speaker Change: You know, ever since the IPO, we have a, there's a chart in our MD&A that shows the volumes for all of our tests. Obviously, at that point, it was just CM and UM, but, and what you can see is with the exception of

Speaker Change: 2020, which was, if you recall, the year that we all let them convince us that some groups of positions were not essential and they closed their offices.

Frank Stokes: But since that time, you see a real, just a very, very clear seasonality pattern on our CM test or melanoma test. And, you know, this year, I think, lines up exactly with what those other, you know, those other years are. So, you know, as we said earlier, quarters, what we've seen is just really just the typical seasonality for the test. I do think at some point, our Sway-Micelle test will become penetrated enough that you'll see similar seasonality there. And we believe the drivers are really related to the number of physician encounters around melanoma, which is related to practice days in offices.

Speaker Change: But since that time, you see a real, just a very, very clear seasonality pattern on our CM test or melanoma test. And, you know, this year, I think, winds up exactly with what those other, you know, those other years are. So, you know, as we said earlier, quarters,

Speaker Change: What we've seen is really just the typical seasonality for the test. I do think at some point...

Speaker Change: Our squamous cell test will...

Speaker Change: become penetrated enough that you'll see similar seasonality there and

Speaker Change: We believe the drivers are really related to the number of physician encounters around melanoma.

Frank Stokes: And Q2 just has the most office days of any of the quarters. You know, Q1 has big physician meetings, two of them. You know, Q3, you've got summer holidays. Q4, you've got winter holidays. So.

Speaker Change: which is related to practice days in offices and in...

Speaker Change: Q2 just has the most...

Speaker Change: The most office days of any of the quarters, you know, Q1 has big position meetings, two of them, you know, Q3, you've got summer holidays, Q4, you've got summer holidays, so.

Subhu Nambi: Q2 has the most days of any kind of physician encounters of any quarter, and that's what drives that very predictable, very regular seasonality. So not much of a surprise to see the pattern this year, and yeah, we think we'll continue to grow our melanoma tests. Of course, it's on a bigger base, so the percentage is lower, but we'll continue to see that grow as we increase penetration.

Speaker Change: Q2 has the most days of kind of position encounters of any quarter and that's that's what drives that very predictable very very regular seasonality so not not much of a surprise to see the pattern this year and yeah we think we'll continue to grow our melanoma test of course it's on a bigger a bigger base so so the percentage is lower but we'll continue to see that grow as we as we increase penetration.

Mark Massaro: Perfect. Thank you, Frank.

Mark Massaro: Thank you. See you soon. Now, we have Mark Massaro with BTIG.

Frank: Perfect. Thank you, Frank.

Mark Massaro: Hey guys, thanks. Yep.

Speaker Change: Thank you, see you soon.

Frank: We now have Mark Massaro with BTIG.

Mark Massaro: Thanks for taking the questions. Yeah, I guess my first one is on just You know, maybe a question that you don't get very often in years, perhaps, is on the commercial payer side. You guys still have relatively immature commercial pay-covered lives on even on your flagship core melanoma test. So, can you just speak about, you know, the frequency with which you try to get in front of these commercial payers, you know, do you have meetings scheduled perhaps later this year, or how are you thinking about getting in front of these, because I see a potential for another leg up in terms of recognizing revenue and pricing from payers that are giving you denials today? So, how should we think about commercial pay, both for melanoma and for SEC?

Speaker Change: You may proceed.

Mark Massaro: Hey guys, thanks for taking the questions. Yeah, I guess my first one is on just...

Mark Massaro: You know, maybe a question that you don't get very often in years, perhaps, is on the commercial payer side, you know, you guys have still relatively immature commercial pay covered lives on even on your flagship core melanoma test.

Speaker Change: So, can you just speak about...

Speaker Change: You know the frequency with which you try to get in front of these commercial payers

Speaker Change: Do you have meetings scheduled perhaps later this year?

Speaker Change: How are you thinking about getting in front of these?

Speaker Change: I see a potential for

Speaker Change: you know, another leg higher.

Mark Massaro: Both for melanoma and for S.

Frank Stokes: So, Mark, the commercial and payer environment is not much different for Castle than it is for other high-value molecular diagnostic testing companies, and the reality is the decision to cover tests significantly lags the development of clinical utility evidence. Said another way, there is ample evidence to support coverage long before that coverage comes. It would be supposition on my part to offer why that is.

Speaker Change: So Mark, the commercial and payer environment is not much different for Castle than it is for other high-value molecular diagnostic testing companies and the reality is the decision to cover tests

Mark: significantly lags the development of clinical utility evidence. Said another way, there is there is ample evidence to support coverage long before that coverage comes. It would be supposition on my part to offer why that is. You can talk to payers or you can, we can all...

Frank Stokes: You can talk to payers, or we can all think about it and probably come up with our own views, but that's pretty typical in the sector and across the industry. What has changed in recent years is the growing number of payers who have outsourced their own technical assessments to lab benefit managers or third-party tech assessment groups. And so when that happens, you're unable to access medical directors and director teams and individual payers because they direct you to the LBMs, the third parties.

Speaker Change: We'll probably come up with our own views, but that's pretty typical in the sector and across the industry. What's changed in recent years

Speaker Change: is the growing number of payers who have outsourced their own technical assessments.

Speaker Change: to lab benefit managers or technical third-party tech assessment groups.

Speaker Change: And so when that happens, you're unable to access medical directors and director teams at individual payers because they direct you to the LBMs, the third parties, and those groups tend to have fairly regular cycles of review.

Frank Stokes: And those groups tend to have fairly regular cycles of review, and they follow them pretty clearly. There is occasionally the opportunity for off-cycle review with those groups, but if you just think it through, there's not much benefit to them to offer an off-cycle review.

Speaker Change: and and they follow them pretty clearly there there is occasionally the opportunity for off-cycle review with those groups but

Speaker Change: If you just think it through, there's not much benefit to them to offer an off-cycle review. And so, even in the case of tests that have significant cost savings to the healthcare system, in many cases, the companies are already providing test results.

Frank Stokes: And so, even in the case of tests that have significant cost savings for the healthcare system, in many cases, companies are already providing test results to patients whose payers are declining claims. And so if you think that through, you're going to a payer and saying, you know, we think you should cover this test because it's going to save you 50 or 70% of the cycles of adjuvant radiation therapy you would pay for otherwise.

Speaker Change: to patients whose payers are declining claims.

Speaker Change: And so if you think that through, you're going to a payer and saying, you know, we think you should cover this test because it's going to save you, you know, 50 or 70% of the cycles of adjuvant radiation therapy you would pay for otherwise.

Frank Stokes: But they understand in many cases that they're already getting that benefit because we are providing the test report to patients anyway. So it's how we think about commercial coverage; we're in favor of it. We certainly agree it would be a positive if we were able to get to that view. And we spend a lot of time and a lot of money working on that process, but it is, unfortunately, fairly opaque and not necessarily one we can directly have, you know, significant influence over on a quarterly basis. Okay, I got it.

Speaker Change: But they understand in many cases that they're already getting that benefit because we are providing the test report.

Speaker Change: to patients anyway. So, it's a...

Speaker Change: How we think about commercial coverage, we're in favor of it.

Speaker Change #100: We certainly agree it would be a positive. We were able to get to that view, and we spent a lot of time and a lot of money working on that process.

Speaker Change #101: It is unfortunately fairly opaque and not necessarily one we can directly have significant influence over from a quarterly basis.

Mark Massaro: And you guys put up a really terrific quarter, and so congrats on that. And, you know, you're baking in SEC Medicare revenues through the end of September. I guess, you know, questions we get from investors are, you know, how should we handicap the extra time that Novitas might need to render their final decision? And so you guys seem perhaps to have some visibility into the end of September. That's more visibility than I have, quite frankly.

Speaker Change #102: Okay, got it.

Speaker Change #103: And you guys put up a really terrific quarter and so congrats on that and you know you're baking in SEC

Speaker Change #104: Medicare revenues through the end of September .

Speaker Change #105: I guess, you know, questions we get from investors are, you know, how should we handicapped...

Speaker Change #106: the extra time that Novitas might need.

Mark Massaro: So just curious if you can give us a sense for, you know, is there any chance that they could be, you know, might need six months, nine months, 12 months? And then the second part of this question.

Speaker Change #106: to render their final decision.

Speaker Change #107: You guys seem, perhaps, to have some visibility into the end of September . That's more visibility than I have, quite frankly. So, just curious if you can give us a sense for, you know, is there any chance that they could be...

Speaker Change #108: You know might need six months, nine months, 12 months. And then second part of this question is

Mark Massaro: is not for Palmetto on your SEC directly, but generally speaking, cause I don't see a ton of reconsideration requests for Palmetto. What is the typical timeline for reconsideration requests and claim appeals? Cause I recognize that Palmetto did not include a lot of really solid evidence that you submitted to them. So I'm just curious if you have a sense, based on your conversations with consultants, what type of timeline a reconsideration request or claim appeal is with Palmetto.

Speaker Change #109: Not for Palmetto on your SEC directly, but generally speaking, because I don't see a ton of reconsideration requests to Palmetto. What is the typical timeline for reconsideration requests and claim appeals? Because I recognize that Palmetto

Speaker Change #110: did not include a lot of really solid evidence that you submitted to them. So I'm just curious if you have a sense, based on your conversations with consultants, what type of timeline a reconsideration request or claim appeal is with Palmetto.

Frank Stokes: Yeah, so Mark, as it relates to the guide and the 1st of October versus any other date, we have the same, you and I have the same visibility there. And that is, as we've said in other quarters when we've updated our guidance, if a contractor follows Medicare's published policies, when a new LCD is finalized, there's a 45 day period before it becomes effective. I am told that it is to allow the computer programmers to make the changes that are necessary and to make the edits in the systems. I don't know if that's the complete story or not because I'm not an expert there.

Speaker Change #110: Yeah, so Mark, as it relates to the guide and 1st of October versus any other date, we have the same, you and I have the same visibility there, and that is, as we've said in other quarters when we've updated our guidance,

Speaker Change #111: If a contractor follows...

Speaker Change #112: Medicare's published policies.

Speaker Change #113: When a new LCD is finalized, there's a 45-day period before it becomes effective. I am told that is to allow the computer programmers to make the changes that are necessary and to make the edits in the systems. I don't know if that's completely correct.

Frank Stokes: And so, as we said before, we are currently a covered test service following a full medical review that was performed in 2022. And so all I'm doing is saying, you know, I'm taking 45 days from today, and I'm not trying to do it by the week. I'm just doing it by the month, and I get to October 1st.

Speaker Change #114: Full story or not, because I'm not an expert there, and so, as we said before, we are currently a covered test service, following a full medical review that was performed in 2022, and so all I'm doing is saying, you know, I'm taking 45 days from today.

Frank Stokes: So that's the visibility there, which has been the same as each quarter. On a reconsideration request, my understanding is the only timeline that's required is to notify you if the reconsideration is going to be granted. Is that correct? And then there's no one-year clock, like from a draft LCD on a reconsideration request. To your point, there aren't a whole lot of precedents there, so it would be difficult to say, you know, here's a sample pool, and we can kind of get to a standard deviation of what we expect it to be.

Speaker Change #114: And I'm not trying to do it by the week, I'm just doing it by the month, and I get to October 1st, so.

Speaker Change #115: So, that's the visibility there, which has been the same as each quarter. On a reconsideration request, my understanding is the only timeline

Speaker Change #115: that's required is to notify you.

Speaker Change #116: If the reconsideration is going to be granted, I think, correct? And then there's no one-year clock, like from a draft LCD.

Speaker Change #117: on a reconsideration. To your point, there aren't a whole lot of precedents there, so it would be difficult to say, you know, here's a sample pool and we can kind of get to a standard deviation of what we expect it to be.

Frank Stokes: Given the cadence of other processes at Medicare, you feel like it's sort of a one-year, maybe a two-year process, but that would be, again, it's not, there's nothing in the manual that directs them there, so that's the, I guess that's the negative, right? That's the negative to the recalibration process. I am the only one.

Speaker Change #117: Given the cadence of other processes at Medicare, you feel like it's sort of a one-year, maybe a two-year process, but that would be, again, it's not, there's nothing in the manual that directs them there, so that's the...

Speaker Change #118: I guess that's the negative, right? That's the negative to the recalibration process. Yeah.

Mark Massaro: So yeah, the history is limited, doesn't tell us what we can do. One would expect that if they had certainly seen or read our submissions last summer, they would have seen the ART in pre-publication form. And that should be, and as you noted earlier, Mark, there have been significant, I think, extremely clear publications in the last four, five, or six months regarding the use of our tests in that manner for ART guidance.

Speaker Change #118: They only...

Speaker Change #118: So yeah, so the history is limited, doesn't tell us what we can do.

Mark: One would expect that if they had certainly seen or read our submissions last summer, they would have seen the ART in pre-publication form, and that should be, and as you noted earlier, Mark, there's been significant

Mark: I think extremely clear publications in the last four, five, or six months regarding the use of our tests in that matter for ART guidance.

Mark Massaro: They know about our STC test because it just finalized the LCD. Does one think that if a reconsideration request goes in fairly soon because it's top of mind, they realize there was a lot of data that's come out that was not included in the review because of timing periods from the Medicare standpoint? Does that say it should be reviewed quicker rather than later? I have no idea how to gauge that, except that it's an interesting possibility.

Speaker Change #119: They know about our SCC test because it just finalized the LCD. Does one think that if a reconsideration request goes in fairly soon, because it's top of mind?

Speaker Change #119: They realized there was a lot of data that's come out that was not included in their review because of timing periods from Medicare standpoint. Does that say it should be reviewed quicker rather than later? I have no idea how to gauge that. Except that's an interesting possibility.
