Very Brief Blog: In Midst of Pandemic, Novitas MAC Tightens Rules for Respiratory Illness Testing

MolDx and Viral Panel Codes

On Monday, January 11, 2022, the MolDx MAC system held a contractor advisory meeting in which a half-dozen experts discussed uses of microbiology panel testing (respiratory, GI, meningitis, etc).  The discussion was somewhat extended and I don't have short bullet-point takeaways from it.   Panelists emphasized that different syndromes were different, different panels and settings were different, patients were individualized, etc.   At some point Noridian will post a transcript of the session. The MolDx system may be considering revising its policy (policies) for panel testing, which currently focus coverage on 5-pathogen-and-less panels.

Novitas Launches Proposed LCD for Viral Panel Codes

The Novitas MAC has released a new policy on respiratory pathogen molecular testing. with a public meeting to be held on January 29, and a comment period open until February 27.

See the Novitas LCD here (DL38916) and the billing article here (DA58575).  


LCD DL38916 Is Very Concise

The coverage section is very concise.  

  • Respiratory panels of 5 and less are covered (1) when timely results can be delivered in an outpatient setting, and (2) clinical management can result in an improved health outcome.

This coverage section has the pro's and con's of 21st Century Cures reforms for LCD structure and process.  The LCD coverage section is supposed state what is covered, why, and when, and not need updating very often.   An attached billing article gives details such as covered CPT code numbers.

In this case, the coverage section is fairly ridiculous, not defining "timely result" and leaving to the reader to figure out when "clinical management results in an improved outcome" to allow even the 3-5 panel tests.

The LCD goes on when an extensive literature review and discussion, including a summary of guidelines.

Novitas held a contractor advisory committee public meeting on respiratory panels in June, 2019, which leaves an audio file and transcript - home page here.  In the LCD, they record CAC members were polled and responded the panels are accurate and may improve outcomes.  The advisory meeting was held long before the COVID pandemic.


Billing Article DA58575

Note that the coding section has covered codes - group 1 - and non covered codes - group 2.   Covered codes including 86731, respiratory pathogens, N=3-5.  2022 codes will be added, including 87428, 87636, 87637, 0240U, 0241U.

The billing article lists a series of non-covered codes, including the standard codes for respiratory pathogens, 6-11 and 12-25 targets (87632, 87633) and a list of 7 non-covered PLA codes for large panels (larger than 5 targets, often around 20). 

The article adds no more to the LCD's superficial rules that results must be timely and can improve patient care.


Zip File

I've put the LCD, article, and 2019 transcript in one cloud zip file here.


You Tell Me: Trends in 87633

87631, '32, and '33 are a triplet of codes for respiratory virus panels, 3-5, 6-11, and 12-25 pathogens.

Interestingly, these codes drop in Medicare utilization from 2018 to 2019.

  • In 2017, national utilization of 87633 was $28M.  
  • In 2018, national utilization of 87633 was $42M.   
    • Remarkably, a great preponderance was in California, with $26M.
  • In 2019, national utilization of 87633 was only $31M.   
    • The delta might be accounted for by the drop of utilization in California, which fell from $26M in 2018 (part of $42M) to only $15M in 2019 (part of $31M).
    • Almost all the utilization in 87633 in 2019 was in So Cal ($15M).   

The national drop from 2018 ($42M) to 2019 ($31M) was probably due to introduction of a MolDx/Noridian LCD, L36315, in mid-2019, which blocks payment to California labs for 87633.

Who Were the Leading Providers of 87633?  Mostly So Cal

Going back to CY2018, when there was $41M of spending on 87633 and $25M in California, the top providers (each with over $1M allowed) were mostly in Southern California.

The top 11 providers (out of 230 providers) billing for 87633, provided $21M of 87633, or about half the national volume.

Very Brief Blog: CMS Leader Seema Verma Checks Out, Notes Many Agency Accomplishment, Minimizes Reference to "Trump"

On January 15, 2021, CMS Administrator Seema Verma left a long essay on the CMS website, describing the numerous accomplishments and achievements of the agency under her tenure of the past four years.

https://www.cms.gov/blog/cms-has-made-lasting-imprint-healthcare-system

Notably, Verma makes NO mention of President Trump's name.  The essay is about 5000 words.



Separately, Verma submitted her resignation letter to President Trump, dated January 14.  The three-page letter was also posted on her Twitter account - here:

https://twitter.com/SeemaCMS/status/1350143114644697090

While the resignation letter necessarily is addressed to President Trump, and thanks him for the chance to lead CMS, I don't believe she mentions his name again. 

I've put both the 13p essay and the 3p resignation letter as PDFs in one cloud zip file here.

____

Yesterday's Blog Predicts This

I had noted yesterday the abrupt disappearance of endless references to President Trump's leadership and President Trumps vision in CMS press releases and headlines (here).  

A New CMS Press Release Today Also Omits Trump's Name

Today's Verma resignation letter and public essay by Verma downplay Trump's name.  Similarly, a new press release today (on a prior authorization final policy) omits Trump's name entirely, although the original draft policy had been released "under President Trump's Leadership."   Here.)


___


Note on tone.  In as much as the resignation letter is addressed to the President, the many uses of "we" might be taken to include him, and at the close, she does thank him for "your leadership."  However, the blog essay also uses "we" and "us" throughout, and never mentions the President directly.


Very Brief Blog: PRIOR AUTH RULE; CMS Finalizes with Blazing Speed, Payers Rebel

CMS released a proposed rule in December regarding EHR and other requirements for Prior Authorization, and conducted an abbreviated comment period that riled some healthcare providers.   

Remarkably, on January 15, 2021, CMS released the final rule (in the inspection copy that precedes Federal Register publication).   This was lightning speed, usually several months (or more) follow after the close of a comment period (January 4).

The rule doesn't so much change the existence of prior authorization, which many providers wish would happen, as change the format and channels for prior authorization.  More advanced methods of electronic communication are required, with visibility in uniform formats to both patients and providers. 

See the CMS fact sheet here.   Press release here.  See the CMS inspection copy final rule here.

The Payer industry disliked the initial rule proposal, and has already pretty harshly slammed the rapidly prepared final rule as half baked and slapdash.  Here.

____

I don't know if this rule will be delayed by the Biden administration or not.  Another rapidly appearing rule, appearing under the unusual mechanism of "interim final rule," on Part B drug pricing, has been under court injunctions to postpone implementation.  Here.  This is the "Most Favored Nation" (MFN) drug price rule that pegs US Medicare prices for drugs to European prices for drugs.
___

Proposed rule press, December 10, here.  The proposed rule press release states:

Today, under President Trump’s leadership, the Centers for Medicare & Medicaid Services (CMS) issued a proposed rule that would improve the electronic exchange of health care data among payers, providers, and patients, and streamline processes related to prior authorization to reduce burden on providers and patients.

In contrast, the January 15 press release on THE SAME RULE, deletes any mention of President Trump entirely.

Today, the Centers for Medicare & Medicaid Services (CMS) finalized a signature accomplishment of the new Office of Burden Reduction & Health Informatics (OBRHI). This final rule builds on the efforts to drive interoperability, empower patients, and reduce costs and burden in the healthcare market by promoting secure electronic access to health data in new and innovative ways. These significant changes include allowing certain payers, providers and patients to have electronic access to pending and active prior authorization decisions, which should result in fewer repeated requests for prior authorizations, reducing costs and onerous administrative burden to our frontline providers. This final rule will result in providers having more time to focus on their patients and provide higher quality care.

Very Brief Blog: AMA Asks for Comments on First-Quarter New PLA Applications

AMA takes PLA code applications quarterly, and posts them for comment for several days.  

See the PLA home page here.  The Agenda of PLA codes for the February 6 CPT Editorial meeting is up at the AMA website, pdf  here.  

As per the Calendar, request permission to comment by January 21.

It looks like there are about 14 code applications, including for the PGDx elio tissue complete test (a 510k-cleared distributed 505-gene tumor test).  Five tests or for MindX RNA tests for memory, pain, mood, stress, and longevity.  



After January 6 Disorder, CMS Stops Referring to President Trump's Leadership

During the Trump administration, routine press releases from CMS have headlined with, or opened with, a touting of President Trump's leadership.

For example: in August, the Medicare Coverage for Innovative Technology (MCIT) policy was proposed "under President Trump's leadership" (here).   The leadership quote was raised from the lead, to the headline, when CMS wrote on the same topic in September (here).  

Policies ensuring "swift" vaccination under a "comprehensive plan" were released "under President Trump's leadership" in November (here).  Changes in renal dialysis payment rules that week also came about "under President Trump's leadership" (here).  And so on.

The phrases "under President Trump's leadership" and "President Trump's vision" seem to have vanished now, after the Capitol riots on January 6.   For example, in the press release that finalizes the same MCIT rule which was headlined under President Trump's leadership just this fall, now there is no mention of the word Trump at all - here.


In remarks this week to ABC, HHS Secretary Alex Azar distanced himself by pointedly framing January 6 as, "The rhetoric last week was completely unacceptable."

Big News: CMS Releases Final Rule on Special Coverage for Innovative Technologies (MCIT)

Last fall, CMS proposed a special coverage rule that would provide automatic, four-year coverage for Breakthrough Devices after FDA approval or clearance.  On January 12, 2021, after market close, CMS released a fact sheet and the final rule, largely as proposed.  It's called Medicare Coverage for Innovative Technologies - MCIT.  The rule also includes a section where they codify in regulation some generic, longstanding Medicare policies about defining "reasonable and necessary," e.g. "meets the patient's need" and "provided by appropriate personnel."

  • See CMS Fact Sheet here.
  • See CMS final rule press release, here.
  • See the final rule text here.  (76pp)
  • The full Federal Register typeset publication will be later.
  • Coverage at MedCity News here.  At MedTech Dive here.
Some facts to know - 

Diagnostics are in.

CMS continued to be a little confusing about diagnostics, but they're eligible.  CMS notes in discussion that it had asked the public whether coverage should apply only to "breakthrough devices" or whether they should "also include diagnostics and drugs."  (Diagnostics are DEFINITELY devices for the FDA, and many have had breakthrough status already).   After repeating that view, CMS states clearly on page 38 of the early release version that any medical device so classified by FDA and reviewed as breakthrough, is covered under MCIT, "including in vitro diagnostics."  Whew.  

Preventive devices are out.

Devices are only covered under MCIT automated coverage if they are otherwise  eligible for coverage.  For example, eyeglass and dental devices wouldn't be covered even if they were MCIT, because they are excluded by statute.  Regular Medicare-covered devices are "reasonable and necessary to treat illness," not primarily "preventive."  It's not clear many preventive devices would be breakthrough status anyway, since BT status includes being intended to treat or diagnose a serious or fatal illness.

Normal Payment Rules Apply.

Normal payment rules apply, so if a product is bundled in a fixed price under a certain setting, the MCIT rule won't have any effect.  

Normal illogical fee schedules and cumbersome coding delays also apply.  CMS makes several remarks that MCIT is only one of their many initiatives to reduce burdens and delays.   Note, too, that CMS opened an office for Technology Payment Policy last November (here).

You Have to Apply

If you went through FDA breakthrough review status, you have to apply for the CMS coverage.  Details will follow.   CMS writes, "Manufacturers simply need to notify CMS of their interest in MCIT for their breakthrough device via an email box and specify the desired start date for coverage.  CMS will coordinate with FDA and the manufacturer to ensure a smooth start to coverage once the breakthrough device is FDA market authorized."  The covered devices under MCIT will have their own CMS webpage.  It looks like your start date can be delayed if you can't ramp up and commercialize as fast as your FDA approval.  

Commercial Payers - attention will be paid.

One notable rule was reference to "commercial payers" as a major determinant of coverage, outside the breakthrough device part of the policy.  CMS is not using this as a hard-and-fast criteria, but rather includes text that between now and 2022, CMS will develop a process through which it might cover something covered by commercial insurers if it does not meet particular Medicare rules provided in the regulation.  

It seems to me that few things covered by most commercial insurers would literally fail to meet Medicare's pretty bland and generic rules (such as "furnished by qualified personnel" and "meets patient's medical need.")  CMS is likely to include a discussion of commercial insurers' positions as part of NCDs and LCDs at some future point, for example.

Implementing Coverage for "Indication for Use."

The Breakthrough coverage is based on "indication for use."  I submitted a comment that sometimes FDA itself vacillates in its approval documents for a device between "intended use" and "indication for sue," but CMS left the final text pointing only to "indication for use."   

Like USPSTF recommendations, FDA "indications for use" aren't always easy to translate into coverage rules (e.g. an MRI scanner might be approved to "image the human body" which isn't a medical necessity scenario for coverage.)   So we'll see how the policymaking over interpreting "indication" text in the labeling plays out.  

Two Year Lookback

CMS offers 4 years of coverage from the time of FDA approval, but will implement MCIT on a rolling basis if devices still have half the time (2 years) left to run.  So 2019, 2020 Breakthrough approvals can apply for coverage.  As CMS states, "Breakthrough devices market authorized within 2 years prior to the date the final MCIT rule became effective will be eligible for coverage."

Volume of Cases?  2 to 4?  Really?

CMS estimates that each MCIT application will require 15 minutes, that there will be 2 the first year, and 3, 4, 5 submitters in each subsequent year (after which applications will "level off.")   

In part, this depends on CMS being aware of only several BT products so far.  See, however, an article in Nature Biotechnology by Johnston et al. (38:933, here), finding there have been 222 products in the BT pathway by January 2020, and the number was rising rapidly.   

In addition, multiple products can enter the BT pathway because there is no approved product (say, 4); and after one of those 4 is approved, the other three remain in the BT pathway.  (4 products might eventually be approved because they entered at timepoints when no product of the type was yet approved).  

Cocktail Party Question: How Far Back Does  This Idea Go?

The idea of giving special coverage status to BT devices goes back at least to 2016; see my history article here (original from August 2019 and survey back to 2016).

CMS Acknowledges BT Devices Might Fail LCDs, Without This Regulation

In the regulatory cost section, at the end of the rulemaking, CMS notes it is aware of at least 2 recent medical devices that were rated substantial advances for new technology add on payments by CMS leadership, but failed to get LCD coverage (that is, had explicit LCD non coverage).  This can't happen again, for BT devices at least, under the rule.

Other Notes

Original version was also posted to Linked In here.

FDA Home Page

See the FDA homepage for the Breakthrough Device program here.  It's a review program - products are admitted in this "review pathway" because they are likely to meet breakthrough criteria and have promising features.  It's not based on the final results of clinical trials and final review.  

Device is expected to provide more effective treatment, or diagnosis, for a life threatening or irreversible condition.   The device must meet ONE of the following;  (1) breakthrough technology per se, (2) no  approved alternatives [LDTs don't count against this, they're not "approved"), (3) significant advantages over approved alternatives, (4) availability is "in the best interest of patients."
___

MCIT & Opposition

The approved policy for MCIT overcomes objections of some academics that CMS should conduct its own review and not be handcuffed to accepted a prior FDA decision -  Neumann & Chambers, here.  

AHIP, the insurance plan group, had opposition to the MCIT proposal (comment here.)  AAMC had concerns that some products might be arbitrarily excluded because of differing interpretations of the amount of Medicare-age patient data (here).
___

Financial Spin

While the market (DJIA) was unchanged on the next day, Renalytix and Exact Sciences were both up about 4%.  Here.   Press release from Renalytix praising CMS for the ruling, here.  For Exact, with a market cap around $25B, a 4% boost is worth about $1B.
___

Wording of Device Indications

I mentioned that device indications are sometimes pretty open-ended at FDA.  

For example, the Lilly Alzheimer PET scan (Amyvid) is indicated "to estimate beta-amyloid density in adult patients who have cognitive impairment who are being evaluated for causes of cognitive decline."  Which patients?  When?  Everybody?   Always?
  
Siemens PET/CT K113448 has a section, "Indications for Use" that simply defines the product as a PET/CT system (not an "indication") then states "the systems are intended to be used by appropriately trained health care professionals to aid in detecting, localizing, diagnosing, staging, lesions, tumors, disease, and organ function for the evaluation of diseases and disorders such as, but not limited to, cardiovascular and neurological disorders and cancer.  The images can also be used to aid radiotherapy planning."   Pretty hard to convert that into a LCD for which PET scans are medically necessary and which aren't.  

_____

References to the White House 

In the CMS "Fact Sheet," CMS quotes President Trump's October 2019 Executive Order on CMS reform.  "[President Trump's Executive Order 13890 focused, in part, on CMS streamlining coverage, coding, and payment for innovative technology, including breakthrough medical devices.  This final rule delivers on President Trump’s order by creating an unfettered path to coverage beginning as soon as the same day as FDA market authorization for breakthrough devices."   

While the policy highlights Trump's E.O., it avoids language sometimes used previously in press releases and fact sheets, which went to lengths to specially laud his vision and leadership several times while announcing a regulation.  "Thanks to President Trump's leadership....Thanks to President Trump's vision for America's seniors..."   These latter types of rhetoric are missing today.

The CMS "Press Release" for MCIT has paragraphs of quotes from Seema Verma, but does not mention President 

Contrast this to the December press release on prior authorization policy, writing, "Today, under President Trump’s leadership, the Centers for Medicare & Medicaid Services (CMS) issued a proposed rule that would improve the electronic exchange of health care data among payers, providers, and patients."

Very Brief Blog: CDC Belatedly Supports Major COVID Sequence Surveillance

Update: Link to new, NYT story at bottom.

___

Last spring, I assumed that NGS sequencing of COVID could help fill in gaps in our public health knowledge (for example, using big data to track the movements and patterns of 200 strains of COVID in a city, when we lacked people and case workers to do so).   Plus, obviously, tracking in real time the appearance of novel virus strain behavior like fatality or contagiousness.   Not so; we've read that the US is something like 30th or 60th in its rate of sequencing COVID in its population.

Timely to see a news wire on January 5, 2021, that CDC is now investing in much larger scale U.S. sequencing studies through HELIX.   

Quote: “Having a robust surveillance effort in place is critical to understanding how the SARS-CoV-2 virus is evolving, and how our public health response needs to adapt,” said Dr. James Lu, M.D., Ph.D., co-founder and President of Helix. “By bringing together the strengths of Helix, Illumina, and the CDC, we were able to quickly evaluate the prevalence of this new variant and take learnings from this effort to better and more proactively characterize future strains that will emerge.”

Very Brief Blog: Final NCD for Colorectal Screening Liquid Biopsy: January 14, 2021?

A quick note to remind us that last fall, CMS announced a proposed national coverage decision on colorectal cancer screening tests.  In the proposed decision - CAG-00454N - CMS will cover blood-based biomarker tests for colorectal cancer if they are FDA-approved and have performance of 74% sensitivity (picking up 3/4 of actual cancers) and specificity of 90% (1 in 10 results are a false positive).   See the proposal here.

According to CMS regulations and proposal tracking sheet, the final decision is slated to appear on January 14, 2020.  Historically, CMS nearly always nailed these due-dates, although in the last couple years, several of them have lagged by several months (e.g. the CAR-T decision).   

There are a number of ins-and-outs to the proposal, for example, annual and biannual test intervals can interact with the sensitivity/specificity statistics, and some tests might be better at picking up advanced adenomas, which don't seem to be counted as the NCD defines tests in terms of cancer metrics.   Nonetheless, if the final decision is more or less in the format of the proposal, it will provide clear measures and accelerated coverage to the multiple colorectal blood tests that are in, or will soon enter, FDA pipelines.   



__

Generally, CMS only adopts new preventive benefits if they are authorized as line items by Congress or if they are adopted via NCDs after they are endorsed by the US Preventive Services Task Force.   Due to nuances of Medicare law, CMS has authority to create new preventive benefits in two areas, colorectal cancer and prostate cancer, based on its direct and de novo assessment of the preventive test technology.  It's unlikely, though, it would review a preventive test prior to FDA approval, and the proposal currently in play is designed to be triggered only after FDA approval.

Very Brief Blog: AMA releases January 1, 2021 PLA Codes

AMA releases new batches of Proprietary Laboratory Analysis codes every quarter.   The new batch for January 1, 2021 is out.  Codes released this week will be effective in one quarter (April 1, 2021) except for COVID-related codes, which AMA releases as "effective immediately" on a rolling basis.

See the home page for PLA codes here:

   https://www.ama-assn.org/practice-management/cpt/cpt-pla-codes

See the codes here:

   https://www.ama-assn.org/system/files/2021-01/cpt-pla-codes-long.pdf

Note that AMA accumulates PLA codes on a rolling basis quarter to quarter, but then cuts this online PDF list back each January, when codes from several previous quarters are officially published in the annual CPT handbook.

Upcoming PLA submission dates are January 7 and April 8.  April 8 submissions will probably be included in the June 2021 CMS annual new test pricing process.

By my count there were about 12 PLA codes released October 1, and only 6 released now for January 1.

The six new PLA codes are,

  1. 0242U, Guardant 360 CDx (FDA-approved LBx test)
  2. 0243U, Perkin Elmer pre-eclampsia biochemical assay
  3. 0244U, Paradigm Diagnostics, MAP Pan Cancer tissue test, 257 genes
  4. 0245U, Interpace Diagnostics, ThyGeNEXT thyroid oncogenes, 47 genes (fusions), includes risk of malignancy
  5. 0246U, San Diego Blood Bank, PrecisionBlood, 51 RBC antigens
  6. 0247U, Sera Prognostics, preterm birth biochemical assay (LCMS)
Regarding Sera PreTRM, see a January 2021 article about a real world study with Anthem, here.





Very Brief Blog: NIH RADx-Funded Novel COVID PCR Device...Being Advertised

 For COVID, emergency use authorizations (EUAs) come in a range of sizes and formats - for lab-developed tests, for test kits to run on big platforms (Thermo Fisher, Roche, Hologic), for compact devices (Cepheid)...and for novel devices.   

I've been uncertain how the timeline for novel devices compares to the other modalities.   I was surprised but happy to see a advertisement for the VISBY device in a new issue of CAP TODAY...suggesting it is well along in the real-world commercialization path.


In September, 360Dx described the device as "Patient-side, Disposable, Molecular PCR Diagnostic Device, a single-use PCR machine the size of a cassette. Founder Adam de la Zerda called the device the 'first and only' single-use PCR instrument up to now and emphasized that everything about the instrument 'has been for single-use.'  "   

The FDA EUA is here.   An October article about its NIH RADx (rapid diagnostics) funding is here.   In September, the company remarked it had filed for CLIA waiver earlier in the year (here).   I believe CLIA-waiver status is still under review.   (In the COVID antigen space, there are EUA and CLIA-waived tests, though).  

The September article also contained the remarks, "[It] doesn't include a service component, which de la Zerda highlighted as a benefit. If the device breaks down, instead of having to wait for a technician to come and fix it, as in the case of a standard PCR machine, the user can just throw it away."

___

According to an October article, CUE Health in San Diego received $481M in federal funding for a novel compact (but not disposable) diagnostic platform for COVID.

I'm not a regulatory expert, but just to mention, there are differences between CLIA-waived for healthcare settings, and FDA permission for home use (like a pregnancy test).  Here, here, here.

Very Brief Blog: CMS Applying CLIA-Waivers to COVID CPT Codes

In Medicare claims processing, CMS processes laboratory CPT codes against edits related to CLIA lab status.   Most lab codes can only be processed for an entity with full CLIA certification, but dozens are "CLIA WAIVED" and this is flagged by added "QW" as a two-place modifier.

On December 23, CMS released some updated QW additions, specifically to the rapid antigen code 87811 and to the multi-antigen code (influenza + Covid) 87428.

Find the CMS source document here:

https://www.cms.gov/files/document/mm12093.pdf


CMS also has a master list of all new and old QW codes online here.  For a MAC webpage with notes on how to use QW, here.  For the full text of R10529OTN, including instructions to MACs on what an EUA is, see OTN10529 here.  OTN means "one time notification."


As occurs with other CMS transmittals, the dates can be quirky.  This one is released December 23, effective October 6, but needs to be implemented (by MAC computers) only by April 5, 2021.
