AI Corner: Can AI Rewrite Bad Molecular Pathology Text?

AI CORNER

Many labs are preparing their "crosswalk presentations" for CMS pricing meetings.  The decks are due May 30 and will presented on June 25.

Labs face the challenge of crafting applications that resonate with diverse audiences. These audiences include (1) CMS physicians, (2) CMS staff without clinical backgrounds, and (3) the CMS lab expert panel, which is composed of expert industry professionals.

Writing a presentation that satisfies all these groups can be daunting, plus, your presentation has to "register" amidst 100 other presentations.  It's like speed dating.  

The CMS PowerPoint template covers several sections, but for this post, I'll focus on "Background,"  "Purpose and Method," and"Resources." To illustrate how AI can assist with this task, I've asked Chat GPT to create a fictional test case, written in the three sections.  

• First, AI generates a hypothetical molecular test, and writes a verbose version with overly long sentences and digressions.   
• (Believe me, this is scary close to first drafts I've seen.)
• Then, AI rewrites the text at "college freshman" and "college junior" levels, demonstrating how AI can enhance clarity, brevity, and focus in scientific writing.

Brief Blog: An Updated View of Third Party Administrators (TPA/ASO)

Much health insurance is directly employer funded, through systems called "administrative services only" ASO or "third party administrators" TPA.   In a new podcast (transcript also available), Elizabeth Mitchell of PBGH, Purchaser Business Group on Health, discussing how this approach to health benefits could be improved.   

She's interviewed by Stacy Richter for the Relentless Health Value podcast (Ep. #436).  Find a summary, a transcript, and the 40 minute podcast here:

AI Corner

A ChatGPT4o Summary.

In episode 436 of the podcast "Relentless Health Value," Stacey Richter interviews Elizabeth Mitchell from the Purchaser Business Group on Health (PBGH). The discussion centers on the inertia present in the healthcare system, specifically related to third-party administrators (TPAs), administrative services only (ASOs), and health plans, and how they impact jumbo employers.

The episode highlights the following key points:

Role of TPAs and ASOs: TPAs and ASOs often act like full health plans, which is not what self-insured employers always need. This leads to additional charges for services that may not be required.

Market Gaps: There is a need for independent TPAs that are not owned by health plans to provide more transparent and efficient services. The acquisition of TPAs by health plans often leads to a lack of true independence and transparency.

Inertia in the System: Despite the challenges, some jumbo employers are taking proactive steps, such as direct contracting with providers, to improve healthcare access, quality, and outcomes. This approach can result in significant cost savings and better care.

Transparency and Accountability: The conversation emphasizes the need for transparent pricing and data sharing between health plans and employers. Federal actions like the Consolidated Appropriations Act (CAA) aim to enforce this transparency.

Direct Contracting: Direct contracts between employers and providers are becoming more common, leading to better alignment and improved healthcare delivery. This bypasses some of the inefficiencies and costs associated with traditional health plan administration.

Challenges and Opportunities: The episode discusses the resistance from health plans to adapt to employer needs and the importance of finding aligned partners who prioritize high-quality care. There is also a call for new market entrants to provide transparent and responsive TPA services.

Mitchell concludes with the interview for greater accountability from health system and health plan executives and emphasizes the importance of collaboration between employers and providers to drive better healthcare outcomes.

UCSF: New paper on state biomarker laws

 See a new paper from UCSF reviewing the latest on state biomarker laws.

https://jamanetwork.com/journals/jama/article-abstract/2818623

Here’s the UCSF press release:

JAMA publication by TRANSPERS Collaborators Addresses Rapid Emergence of State Biomarker Testing Insurance Coverage Laws.  

In JAMA article published May 13, The State of State Biomarker Testing Insurance Coverage Laws, by Lin et. al., the authors tackle the complicated topic of states legislating access to medical care. In response to perceived barriers to access to care, states have enacted legislation to mandate terms and conditions of insurance coverage for a variety of circumstances, such as cancer screening and mental health treatment parity. Recently, there have been increasing numbers of states that have passed legislation mandating that insurers cover “biomarker testing.” 

This review of legislation from 15 states mandating coverage of biomarker testing finds that their impact may be limited by their lack of reach and implementation challenges. While these laws attempt to expand access to coverage, that may not always be the case since more than 50% of the population may not be covered by legislative mandates governing insurance coverage. Additionally, such insurance mandates may not affect inequities in access. Finally, there is little guidance for implementation in the legislation. 

The authors conclude that current laws are likely to have limited effect, particularly concerning improving health equity, and additional approaches will likely be needed to improve patient access and outcomes. 

This study was led by Grace Lin, MD, MAS (UCSF School of Medicine) and TRANSPERS (UCSF Center for Translational and Policy Research) founding director Kathryn A. Phillips, PhD, with Janet Coffman, PhD, MPP, MA (UCSF Institute for Health Policy Studies). TRANSPERS is in the Department of Clinical Pharmacy at UCSF and is affiliated with the Philip R. Lee Institute for Health Policy Studies.

State Biomarker Testing Insurance Coverage Laws: 

An Overview

The landscape of state biomarker testing insurance coverage laws is rapidly evolving, driven by the need to address disparities in healthcare access. These laws mandate insurance coverage for biomarker testing, particularly for cancer subtypes, to ensure patients can access necessary treatments. However, the effectiveness and impact of these laws remain under scrutiny.

Legislative Efforts and Challenges

States have enacted various laws to improve access to cancer screenings and mental health treatments, yet the effectiveness of such mandates is debatable. For instance, mental health parity laws have had limited impact on service usage and spending. With biomarker testing, barriers like cost and inconsistent insurance coverage persist, leading to advocacy for legislative mandates.

Current State Laws

Since 2021, fifteen states have passed legislation requiring coverage for biomarker testing, with twelve including Medicaid. These laws generally define biomarkers similarly and do not exclude specific tests. Most require coverage for diagnosis, management, and monitoring, but not for screening.

Implementation and Effectiveness

The laws face challenges in implementation due to their broad language and lack of specificity. Issues like FDA approval focus on safety and efficacy rather than clinical utility, potentially complicating coverage decisions. Moreover, state mandates may not significantly impact those most affected by healthcare disparities, such as the uninsured or certain Medicaid populations.

Policy Implications

The impact of state biomarker testing laws is limited by their reach and implementation challenges. Policymakers and stakeholders must monitor these laws' effects and explore additional strategies beyond insurance mandates to enhance access and equity in healthcare. Non-legislative programs or federal legislation may be necessary to achieve broader, equitable access to biomarker testing.In conclusion, while state laws mandating biomarker testing coverage are a step toward improving access to personalized cancer treatments, their current limitations suggest that a multifaceted approach is essential to address ongoing disparities in healthcare access and outcomes.

Brief Blog: Molecular Pathology Industry Is Pretty Capital Intensive

Header: Exact Sciences May 2024 investor call:  Molecular testing is capital-intensive, and sales and marketing need to be on the upswing again.   

###

During COVID, there was an public equities bubble (for public companies) or a valuation bubble (for nonpublic companies) in both biotech and genomics.   Since 2023, funding has been more challenging.

One example of the principal, "it takes money to make money" aka "it's capital intensive" is in the latest investors call at Exact Sciences (Cologard; Oncotype).   Revenue has risen from $1.5B in 2020, to $2.5B in 2022.   At the same time, operating losses have been substantial (-$558M in 2020, -835M in 2021, -577M in 20222, and -214M in 2023).   

Efficiency, in dollarized terms, has improved.  Revenue in 2020 ($1.5B) was less than operating expenses ($1.7B), but revenue ($2.5B) was greater than operating expenses ($2.1B) in 2023.  

 

But you have to spend money to make money; $2B of operating expenses (and $650M in COGS) are big numbers.  Here's a quote from the investor call which was highlighted by Jack Meehan at Nephron Research:

...We turned down our sales and marketing investments, as you know, over the last year and really over the last couple of years, while we saw about approaching $1 billion of growth. 

And the truth is we probably turned that down a little bit too much. We recognized that at the back end of last year. And starting in Q1, we increased our marketing investments...

And it's clear the more time, the more frequently our reps call on an office in a position or a nurse or physician assistant, you see a straight-line increase with no flattening from zero to six calls per quarter. That gives us confidence that by adding reps, we will see it. ,,,You will see an increase in the total number of test orders. 

Professional sales staff for up to 6 calls, per quarter, is part of that substantial total SG&A in molecular pathology.

As Meehan concluded in his note, "You have to spend money to make money," and the capital intensivity is a kind of moat.

My blue text highlights a few places I thought the AI made a point worth keeping.

###

You are an expert lab industry business consultant.   I, too, am a business consultant for the lab industry.    

In the clinical lab industry today, lab test kits may be sold as "IVD" kits, which are fully FDA approved, or "RUO" kits.   RUO kits are not sold as FDA approved, but local labs can validate them and then use them in clinical care.    FDA policy changes promise to radically change this system.   Under the new FDA regulation, which has been finalized, FDA will not allow RUO kits to be validated and used clinically by local labs.   Instead, only FDA approved IVD kits will be permitted.     

My client is ABC, which is a leading manufacturer of both IVD kits (for the most popular tests, justifying the FDA costs) and RUO kits (for a wide range of less popular tests, where the IVD investment would be uneconomical.)   ABC asks if it should start investing in converting its catalog of RUO kits to IVD kits, a large and time consuming investment.  However, it would be worthwhile if in the future, labs are "handcuffed" to buying IVD kits only.    But there are many complicating variables.   The FDA regulation will not be enforced until 2027.   Between now and then, the regulation may be canceled, changed, or delayed.    To clarify, for example, the client ABC could invest $100M in FDA approvals, but if the FDA rule is canceled, clients will only want to buy the cheaper RUO kits (which are today's status quo.)   

How can the client ABC think about the threat and opportunity to its business model, and how would you advise the commercial teams (sales), the R&D teams, and the C-level leaders of ABC.

ChatGPT

Navigating regulatory changes like the one proposed by the FDA, which would prohibit the clinical use of Research Use Only (RUO) kits unless they are FDA-approved as In Vitro Diagnostics (IVD), poses a significant strategic challenge for companies like ABC. Here’s a strategic approach you might consider in advising ABC's teams on handling this situation:

MolDx Heavily Edits A45795, MolDx Billing for Targeted vs Comprehensive Tumor Panels

Moldx has an elaborate article regarding billing and coding of tumor panels - A54795, which is now up to "revision 16."  Find it here:

https://www.cms.gov/medicare-coverage-database/view/article.aspx?articleid=54795&ver=42&bc=0

What's New?

It may take a master's degree in "MolDxology" to decipher some of this, but here's their handy guide to what you have to know about this revision.

Under Article Title revised to MolDX: Targeted and Comprehensive Genomic Profile Testing in Cancer. 

Under Article Text subsection heading Next Generation Sequencing (NGS) 2nd sentence revised “tumor tissue only-based panels” to read “tumor-based panels for cancer that may be performed by NGS”. Added verbiage and hyperlink for “Refer to MolDX: Defining panel services in MolDX A59678 for further guidance on the distinction between single analyte tests and panel tests”. Under subsection heading Targeted Tumor Panels revised 1st sentence “Targeted Next-Generation Sequencing (NGS) panels” to read “Targeted tumor panels”. Revised 2nd sentence to read “Generally, these panels are limited to specific variant types at defined sites, such as single nucleotide variants (SNVs), small insertions or deletions (INDELs), single site copy number variants, or gene fusions”. Revised last sentence to delete “regions in the genes” and replaced with “targets”. Under subsection heading Comprehensive Genomic Profile (CGP) Testing revised 1st sentence “CGP” to read “CGP testing”. Revised 4th sentence “CGP” to read “CGP tests” and replaced “copy number alterations (CNAs)” with “copy number variants (CNVs)”. Revised 5th sentence to add “and chromosome abnormalities such as loss of heterozygosity (LOH)”. Revised 6th sentence “CGP” to read “CGP testing”. Added new sentences “CGP tests are expected to yield information of clinical relevance beyond a targeted panel, for example, to identify relevant clinical trials for patient management or identify possible therapeutic interventions for off-label use. It is expected that a CGP will identify all clinically relevant information attainable for the type of service performed”. Revised subsection heading “Targeted Panels” to read “Targeted Tumor Panels”. Revised 1st sentence to read “To bill for DNA-based panels that measure SNVs, INDELs, CNVs or rearrangements, review CPT codes 81445 and 81450” and deleted 2nd and 3rd sentences. Added new sentences “If a DNA-based targeted panel meeting the coverage requirements is used, and MSI is also performed, 81457 can be billed. If a DNA-based targeted test meeting coverage requirements is performed that includes MSI and CNVs, 81458 can be billed” and 2 new paragraphs. Revised last paragraph “DEX Z-Code™” to read “DEX Z-Code®”. Under subsection heading CGP deleted first paragraph and added new paragraph. Revised 2nd paragraph 1st sentence to add “81459 or” and replaced “DEX Z-Code™” with “DEX Z-Code®”. Revised 2nd sentence to replace “other” with “further”. Revised 3rd paragraph sentence “DEX Z-Code™” to read “DEX Z-Code®”. Formatting, punctuation, and typographical errors were corrected throughout the article.

Got that? Quiz Tuesday.

Notably, one standout is that (while they never accepted 81455) they will accept 81459 instead of 81479 in some circumstances.  Note, though, that under separate current gapfill processes, 81459 is to be paid at $2990, basically the same as 81455.

MolDx Publishes Major Guidance Document: When Pathologists Can Order Molecular Tests

Famously, CMS has a regulation (42 CFR 410.32) that tests must be ordered by a physician who is treating a patient for a particular disorder.  However, CMS provides some exceptions where pathologists (or radiologists) can adjust orders or, for pathologists, implement orders necessary to complete a case.   (The example provided is seeing possible bacteria and running a special stain).  

(For additional clarification, see Medicare Benefits Manual 80.6, and the original Fed Reg creation of 410.32 at 10/31/1997, 62 FR 59048).

MolDx has published an important public policy article about when a pathologist can order molecular tests.  Find the article here:

https://www.cms.gov/medicare-coverage-database/view/article.aspx?articleid=59741&ver=2&bc=0

• The article  is very important because of the need for timely molecular testing in conditions such as cancer.  
• The guidance also has important guidance that a test order form and its clinical information is "part of the medical record" for audit purposes.
• Rather than summarize the guidance, I will cut/paste below.   
• Articles get updated, so always check the current version online..

##

##

A59741

Documentation requirements for laboratory services require that services be ordered by a treating physician as defined in IOM 100-02 Chapter 15 §80.6.1 and meet other criteria set in 42CFR§410.32(b). Further clarifications were made in ICN MLN909221, December 2020.

In view of these requirements, this contractor provides the following supplemental clarifying information:

• Pathologists may order molecular diagnostic services when they fall under exemptions to the “treating physician” requirements as defined in the Medicare Benefits Manual 100-02 Chapter 15 sections 80.6.3, 80.6.4, or 80.6.5. Most commonly, pathologists may order molecular diagnostic tests when performing diagnostic services from a sample submitted to them without a specific test order. In such instances, the pathologist must meet all the criteria listed in section 80.6.5. This includes ensuring the service is reasonable and necessary, the results are communicated, and that the pathologist documents why the service was performed in their report. 
• A pathologist may also order additional testing as defined in the above exemptions after the completion of an ordered service (molecular pathology or other pathology service) when that service is medically necessary and a delay in the performance of the test would have an adverse effect on the care of the beneficiary.
• Test requisition forms are part of the medical record. When requisition forms include complete information validating medical necessity, such as qualifying clinical information that demonstrate test coverage criteria are met, the requisition form may be sufficient to determine if the service is reasonable and necessary without other medical information from the ordering provider. 
• If the requisition form does NOT contain sufficient and relevant clinical information to determine if the service is reasonable and necessary for the intended patient, the requisition form is NOT considered sufficient to meet reasonable and necessary requirements and additional documentation may be required to fulfil this criteria.
• A “wet signature” is NOT required for clinical diagnostic tests and electronic signatures are acceptable if they confer an attestation that the physician is placing the order. A signature is also not required on orders for clinical diagnostic tests paid on the basis of the clinical lab fee schedule, the physician fee schedule, or for physician pathology services (IOM 100-02 Chapter 15 §80.6.1), provided that there is other evidence in the medical record that there is intent to place an order. 
• However, it should be understood by providers that the most common reason for improper payment upon review is insufficient documentation, and it is best practice to ensure there is a signed order in place.

Nerdy Blog: Gapfill 2024 & Algebra-AI for Genomic Sequencing Procedures (GSP)

 A few days ago, I produced a fairly standard assessment of the 29 codes under the "Gapfill" process in 2024.  Find it here:

https://www.discoveriesinhealthpolicy.com/2024/05/cms-releases-preliminary-gapfill-rates.html

Key takeaways are that the gapfill process for new genomic sequencing procedures (GSP) will be impactful, and that extra attention will probably be paid to the first-ever liquid biopsy GSP codes.  

This is the first shake-up to the GSP coding and pricing system in a decade.  Generally, the old system was simply with 5-50 tumor genes paying about $600 and 51 or more genes paying about $2900.

I also noted that there is probably more discrepancies among the MACs than ever before.  But regardless of how low or high other MACs set gapfill prices, the only prices that matter are MolDx's, because CMS sets final prices to the median, and that is controlled by MolDx.  Still, for the six genomic sequencing procedure codes at the top of the report, the MolDx prices add to $10,762, the Novitas prices to $19,741, and the NGS MAC prices to S11,203.

###

In this new blog, we use Chat GPT to analyze the MAC prices across the GSP codes.

First, I took the GSP codes under gapfill, and put them in a single table with pricing offered by MolDx, by Novitas, and by NGS MAC.  

Next, I added columns for the key variables (features) of the new codes, copying this from an AMA CPT table.   For example, some codes include Tumor Mutation Burden, some don't.

Next, I assigned algebraic letters to each test feature, as follows.

• A, DNA only.
• B, DNA-RNA.
• C, SEQ
• D, copy number variation.
• E, MSI.   
• F, TMB,   
• G, rearrangements.
• H, liquid biopsy format.

That results in the following equations:

• A+C+E=897 81457
• A+C+D+E=1046 81458
• B+C+D+E+F+G=$2990 81459
• H+B+C+D=$1196 81462
• H+A+C+D+E=$1345 81463
• H+B+C+D+E+F+G=$3290 81464

This is 6 equations in 8 unknowns, which does not have a general solution.  However, you can still solve for some variables, or elucidate contradictions.  Basically, what CHATGPT did is exactly the same as a kid solving A+B=10 and B=6 therefore A=4.  In the larger system just shown, ChatGPT comes to this impasse:  It appears that the system of equations is overdetermined, meaning that it has more constraints than variables to solve for. This could imply either a contradiction in the equations or the need to remove redundant equations.

Here is a summary lifted the extensive CHATGPT4 analysis to try and parse the MolDx prices vs the AMA CPT features.  (Read, or skim, the GPT4 analysis at the prior link.)

####

GPT Says:

Having more variables than equations generally leads to an underdetermined system, which often has infinitely many solutions or might not have any. However, even in such cases, as you mentioned, it's possible to make inferences about the relationships between the variables and detect inconsistencies if they exist.

Key Learnings from the Equations Today:

Finding the Relationships:

We were able to deduce that 

𝐷 = $149 (CNV)

A + E = $149 also. (DNA anal. plus MSI)

H= $300.  (LBX)

Spotting Redundancies:

We identified that some equations were redundant, which happens when one equation can be derived from another or from a combination of others.

Highlighting Inconsistencies:

By simplifying the equations, we found that some results were contradictory, indicating an inconsistency in the given system.

For the Student: Practical Approach:

In cases where a system of linear equations has more variables than equations, it's useful to:

• Solve for Dependencies:
• As we did, find relationships between variables to reduce the number of unknowns.
• Check for Redundancies:
• Test whether some equations merely repeat information already expressed in other equations.
• Look for Inconsistencies:
• Simplify and combine the equations to see if contradictions arise, which can highlight any errors or issues.
• Conclusion
• Even without explicit solutions, you can gain insights into the relationships between variables and test for inconsistencies or redundancies, which is a valuable approach when faced with similar problems in the future.

The equations with MolDx prices, could be replaced with NGS MAC prices, but they are generally very similar (not identical, though) to MolDx prices.   the MolDx prices could be replaced with Novitas prices, but the latter show very little "spread" among the 6 codes.

Least Promising Initiative: AISight Introduction for Research Use Only

The introduction of the AISight Image Management System labeled for "Research Use Only" seems to be the least immediately promising initiative compared to others that have broader commercial applications. While still significant, its impact is more limited because:

Limited Market Application: The designation "For Research Use Only" restricts the use of AISight to non-diagnostic applications, limiting its immediate commercial potential and revenue generation capabilities. While important for advancing research and development, the inability to apply these tools directly to clinical diagnostics can delay the realization of their full market potential.

Delayed Commercial Impact: Although essential for validation and further development, the focus on research applications means that the benefits of AISight in improving patient care directly are deferred until it can clear the regulatory hurdles for clinical use. This prolongs the timeline for seeing a direct impact on healthcare outcomes and financial return from this product line.

Regulatory Challenges: The transition from a research-only tool to a clinically approved system can be fraught with significant regulatory challenges and require substantial investment in further development and compliance activities. This can strain resources and divert focus from other potentially revenue-generating projects.

While the AISight system’s introduction for research use is a strategic step for future clinical applications and advancements in AI-driven pathology, its immediate impact and promise are overshadowed by initiatives like the Quest Diagnostics collaboration that have more direct paths to commercialization and market influence.

##

Products sold and marketed as research use only (RUO) may be validated under CLIA for medical use in a specific lab, after validation.  Does that change your assessment of the least favorable proposal.

ChatGPT

The clarification regarding the potential for "Research Use Only" (RUO) products to be validated under CLIA (Clinical Laboratory Improvement Amendments) for medical use in specific laboratories indeed shifts the perspective on the immediate and practical value of the AISight Image Management System. This possibility means that while the AISight system is initially restricted to research applications, it can be adapted for clinical diagnostics through validation processes in CLIA-certified labs. Here’s how this information might affect the assessment:

Revised Consideration of AISight as an Initiative:

Pathway to Clinical Application: The ability to validate AISight under CLIA for clinical use substantially enhances its potential impact. Once validated, it can be used in diagnostic settings, thus broadening its market applicability and enabling PathAI to capitalize on its technological advancements sooner than if it had to undergo the full FDA approval process for a clinical indication.

Strategic Market Entry: The CLIA pathway offers a strategic advantage for introducing new technologies into the healthcare market. It allows PathAI to gather real-world data and refine its AI algorithms within a clinical context, which can be leveraged to strengthen subsequent regulatory submissions for broader clinical use.

Revenue Opportunities: Even during the initial RUO phase, AISight can generate revenue through collaborations with research institutions and biopharma companies. The transition to clinical diagnostics can then open up more substantial and stable revenue streams from healthcare providers and pathology labs.

Enhanced Product Development: Early usage in a clinical environment, under CLIA validation, can provide critical feedback and data, accelerating improvements and adaptations that enhance the system’s effectiveness and market readiness for broader diagnostic use.

Conclusion with Revised Perspective:

With this additional pathway for clinical deployment through CLIA validation, the AISight Image Management System's initiative gains a more promising outlook. It suggests a more immediate and impactful application in the medical field than initially assessed. The capacity for CLIA-certified labs to validate and use AISight for diagnostic purposes not only mitigates some of the commercialization risks associated with the RUO designation but also positions PathAI to more rapidly influence and penetrate the clinical diagnostics market.

Given this revised understanding, the initiative involving AISight’s introduction for research use now appears significantly more favorable. It facilitates a practical and regulatory-savvy approach to market entry and expansion, enhancing PathAI’s ability to implement AI-driven innovations in pathology more broadly and effectively.
