Pulse: CMS Fee Schedule changes coming

# CMS Proposes Revaluing 88305 RVUs After Maryland Claims Analysis ## SummaryCMS is reconsidering RVUs for pathology codes 88305 and 88307 after the Maryland Health Care Commission analyzed 2023 all-payer claims data using CMS's own 25-minute intraservice time assumption. The analysis found 1,763 provider-days where 88305 alone implied more than 8 hours of work, and 587 days exceeding 24 hours. A 2016 Urban Institute pilot study (three sites) reported a 2-minute median intraservice time for 88305. CAP has scheduled an August 12 webinar on the proposed changes. The hosts argue the methodology ignores workflow reality — easy cases signed out quickly by dermatologists and gastroenterologists, with complex cases referred to pathologists — and call for the field to aggregate its own data to defend against sparse studies driving policy. ## Key takeaways- CMS assigns 25 minutes of intraservice physician time to 88305 for RVU calculation; no time is submitted on claims.- Maryland's 2023 APCD analysis multiplied 88305 volume by 25 minutes, producing 1,763 provider-days >8 hours and 587 >24 hours.- The 2016 Urban Institute time-motion study (n=3 sites) found a 2-minute median for 88305 — used to argue 12–13x overpayment.- Dermatology and GI clinicians often sign out easy 88305 cases (small biopsies) and refer complex cases to pathologists, skewing volume-time ratios.- CAP announced the proposed revaluation and hosts a webinar August 12, 2026.- The field lacks a centralized claims/outcome database to counter sparse studies; hosts suggest building one. ## Chapters- Opening Studio Updates Personal Chat- CAP Announcement CMS Fee Schedule- Maryland Study Challenges 88305 Time- CMS RVU Methodology Time Assumptions- Maryland Letter 2016 Pilot Study- Pathology Workflow Reality Check- Provider Day Data Deep Dive- CMS Next Steps August Webinar- Field Needs Data Aggregation Strategy (00:00) - Hook (00:33) - Intro (00:45) - Opening Studio Updates Personal Chat (03:25) - CAP Announcement CMS Fee Schedule (04:13) - Maryland Study Challenges 88305 Time (08:22) - CMS RVU Methodology Time Assumptions (09:53) - Maryland Letter 2016 Pilot Study (11:52) - Pathology Workflow Reality Check (14:22) - Provider Day Data Deep Dive (19:36) - CMS Next Steps August Webinar (20:41) - Field Needs Data Aggregation Strategy (22:41) - Outro

Pulse: ADLM Signals, Cyclospora Surges, and CLIA Redraws the Lab

# ADLM Signals, Cyclospora Surges, and CLIA Redraws the Lab ## SummaryChris and Aakash break down three major signals from ADLM 2026: simultaneous centralization of high-throughput systems and decentralization of point-of-care testing, AI shifting from demos to implementation reality with data infrastructure as the real bottleneck, and the Cyclospora outbreak exploding to 4,200 confirmed cases across 41 states. They also unpack CMS and CDC's request for information on modernizing CLIA (last updated 1988) for AI-assisted diagnosis, remote oversight, and data-only facilities, plus the FDA-approved Elecsys sFlt-1/PlGF ratio test for pre-eclampsia risk stratification in hospitalized pregnant patients 23–34 weeks gestation. ## Key takeaways- **Centralization and decentralization are happening simultaneously** — vendors are building massive high-throughput analyzers for core labs while pushing smaller instruments closer to patients, creating a "mismatch" in product strategy.- **AI implementation has moved past the demo phase** — the real questions now: who monitors data drift, who owns the data, who tracks software versions, and how performance varies across patient populations.- **Data infrastructure is the bottleneck, not algorithms** — companies gaining traction (like Bunker Hill) function as infrastructure plays, solving how to connect to health system databases; CAP is prioritizing AI inspection frameworks.- **Cyclospora outbreak is not slowing** — 4,200 lab-confirmed domestic cases, 7,400+ probable cases under investigation, 300+ hospitalizations, 41 states; CDC warns reporting lags illness onset by ~6 weeks; linked to Taylor Farms iceberg lettuce recall (~2,000 confirmed cases).- **Testing gaps obscure true outbreak scope** — Cyclospora isn't on routine GI panels; genetic tracking is harder than Salmonella (no whole-genome sequencing); labs may need to spin up testing if this becomes seasonal.- **CLIA modernization RFI is a critical inflection point** — CMS/CDC asking whether AI-assisted interpretation constitutes a "test," whether data-only facilities count as labs, and how remote competency assessment works for 90+ clinic locations.- **FDA-approved pre-eclampsia test (Elecsys sFlt-1/PlGF ratio)** — 91% sensitivity, 77% specificity for predicting severe pre-eclampsia within 2 weeks in singleton pregnancies 23–34 weeks; intended to support (not replace) clinical judgment; education needed to prevent off-label confirmatory use. ## Chapters- Opening and Personal Catch Up- ADLM Signals Overview- Centralization and Decentralization Trends- AI Implementation Beyond Demos- Data Infrastructure as AI Bottleneck- Cyclospora Outbreak Escalation- CLIA Modernization Request for Information- FDA Approved Pre-eclampsia Test ## Mentioned- **ADLM** (Association for Diagnostics & Laboratory Medicine) — 2026 conference- **Bunker Hill** — health AI company focused on data infrastructure/connectivity- **CAP** (College of American Pathologists) — prioritizing AI inspection frameworks- **CDC** — Cyclospora outbreak tracking, reporting lag warnings- **CMS** — CLIA modernization request for information (with CDC)- **Taylor Farms** — iceberg lettuce recall linked to Cyclospora- **Elecsys sFlt-1/PlGF ratio** (Roche) — FDA-approved pre-eclampsia risk test- **CLIA** (Clinical Laboratory Improvement Amendments) — 1988 legislation under review ## Quotes> "The data infrastructure they call it a layer... is going to be as important as anything else as far as AI implementation... a lot of the health AI companies that are actually gaining real traction are almost like infrastructure companies." > "The core important questions still need to be asked as, like who monitors the data drift, who owns that data? Who tracks these software versions and like who checks the performances differences amongst different patient populations." > "It used to just be build the walls higher and thicker, right? That's pretty much what we thought of and now it's a very different world."

Deep Dive: Disruption in the Laboratory

What is Disruption in the LaboratoryDefining disruption requires looking at workflow and ROI rather than just technical novelty. SummaryMarket disruption in the lab is not automatically signaled by new technologies or game-changing results. True disruption addresses underlying economic, workflow, and staffing bottlenecks. The focus should be on whether a technology simplifies the lab's work or shifts complexity elsewhere, ultimately impacting the return on investment for the institution. Key takeaways* Disruption in the lab must address underlying economics, workflow, and utility of results, not just technical novelty.* Novelty alone does not equal disruption; it must solve a specific operational problem like staffing shortages or diagnostic delays.* The key question is whether a technology removes more complexity than it creates for laboratory personnel.* Disruption often involves shifting value capture: the lab may implement a change that benefits the clinician, making the sale harder to justify internally.* Physical AI solutions, like robotics, represent disruption by automating manual physical processes, which can be a path forward.* New testing methods must simplify bench work for fungal or microbiology teams rather than just expanding the scope of testing.

Deep Dive: The DMT Defined (Part 2 of 6)

DMT Defined Defining what a DMT is and what it is not. Summary The discussion focuses on defining Diagnostic Management Teams (DMTs) by emphasizing that a true DMT must be expert-driven, patient-specific, and aim to establish a single diagnosis in the context of the patient's illness. It contrasts this with simpler processes like reflex testing or utilization management, highlighting the need for comprehensive interpretation rather than just providing test results. Key takeaways A DMT must recommend necessary tests and provide a patient-specific diagnosis within the clinical context.The value of a finding depends on whether it is provided at a time when clinical decisions are being made.Reflex testing is a tool, not the DMT itself; the DMT establishes the diagnosis based on that information.A true DMT requires expert-driven input and aims for a single diagnosis, unlike utilization management which focuses on groupthink.The process needs to be patient-specific, requiring time, which is why it is often avoided in favor of case conferences for less complex issues.Chapters 0:00 Defining What A DMT Is 1:10 The Evolution Of DMTs 3:29 Critical Ingredients Of A DMT 12:45 DMT Versus Utilization Management 14:04 Reflex Testing Is Not A DMT 37:10 Checklist For Real DMTs Mentioned Dr. Michael Appasada, Penn, Mass General, Spalding Rehabilitation Hospital, Amazon One, Amazon Health, Open Evidence AI, Plavix. Quotes > You have to say what tests are necessary and you have to provide a diagnosis for that patient, patient specific in the clinical context of that patient. > It is a consult that is expert driven and patient specific in the context of the patient's illness. And its goal is to conclusively establish a single diagnosis. > Reflex testing is not the DMT because reflex testing says to figure out the diagnosis, you would want to do this test first based upon that you do this test or that test.

Pulse: Can Labs Keep Up? Workforce, Quality, and AI in Modern Laboratory Medicine

Workforce and AI in Laboratory Medicine Summary The medical laboratory workforce faces a shortage compounded by retirements, requiring systemic changes in education. Guidance from CAP focuses on structuring case review to reduce interpretive errors. Furthermore, the integration of AI into lab medicine is moving toward validation stages, leveraging the standardized numeric data inherent in laboratory results. Key takeaways The laboratory workforce shortage is not just about vacancies; it involves losing decades of experience through retirements, making it harder to backfill roles with equivalent expertise.MLS and MLT education must become a forefront field to address the shortage, requiring significant investment, such as proposals for establishing medical or MLS schools.Diagnostic error reduction guidance requires inter- and intra-divisional assessment of sign-outs to reinforce a structure for evaluation rather than seeking perfection.Laboratory medicine data—numeric measurements—is ideally suited for AI implementation because it is straightforward, unlike free-text physician notes.The future involves labs being involved in the validation and verification stage of AI development, ensuring models accurately reflect laboratory results.Chapters 0:54 Workforce Crisis In Labs 6:06 Diagnostic Error Reduction Guidance 8:59 AI Solutions In Healthcare 14:20 Lab Medicine And AI Future 16:46 Final Thoughts On Topics Mentioned CAP, AMA, Microsoft, ChatGPT, Anthropic.

Field Notes 1: UAMS and MLS Training

Field Notes 1: UAMS and MLS Training The challenge of staffing Medical Laboratory Science positions, particularly in rural areas, and a scalable solution for recruitment. Summary There is a significant shortage of Medical Laboratory Science staff, especially in rural settings, which creates severe staffing challenges for hospitals. The University of Arkansas for Medical Sciences developed an approach to address this by training personnel locally rather than requiring relocation, which proved effective in attracting and retaining talent. Key takeaways Unfilled MLS positions are in the eight to ten percent range nationally.Unfilled rural MLS positions are significantly worse, at 15% or higher.Moving staff from metropolitan areas to rural communities for training is less effective than training locally.A successful model involves allowing trainees to stay in their community while completing training and continuing employment.The Arkansas program has achieved a 100 percent pass rate on board exams.This approach offers a scalable model for addressing healthcare staffing needs in rural areas.
