What CMS needs and when
Under the Protecting Access to Medicare Act, applicable laboratories must report the private payer rates and volumes they were paid for each test code. The current reporting window runs from May 1 to July 31, 2026, and covers services furnished from Jan. 1 through June 30, 2025. The Consolidated Appropriations Act, 2026, enacted Feb. 3, set those dates after years of delay. CMS posted an updated FAQ this week and has mailed letters to hospitals it believes run outreach labs that likely must report.
Whether a hospital outreach lab must report depends on how it bills. A lab that bills under the hospital’s NPI is tested only on its non-patient outreach business billed on the 14x type of bill. A lab with its own NPI is tested on all of that NPI’s Medicare revenue. Either way, the lab must hold a CLIA certificate, get more than half of its Medicare revenue from the clinical lab and physician fee schedules, and have at least $12,500 in clinical lab fee schedule revenue during the collection period. CMS notes that most outreach labs will pass the majority test, so the dollar threshold often decides the question.
Why it matters beyond compliance
Medicare will pay each test at the weighted median of the private rates reported. If hospital outreach labs do not report, the median will reflect mostly the rates of the labs that did, which may not look like a hospital’s commercial contracts. Payment cuts have been frozen since 2021, but starting in 2027 rates may fall by as much as 15% a year through 2029, a phase-in that the proposed 2027 physician fee schedule would put into effect.
There is also direct risk. CMS can impose civil penalties of up to $10,000 a day, adjusted for inflation, for each failure to report or each misrepresentation.
Questions for this week
- Do we qualify? Have revenue cycle and lab leaders run the threshold test for every outreach lab and NPI, and document the result.
- Is the data clean? Only test-level private payer rates count. Bundled or claim-level payments do not. Check how denials, adjustments and secondary payments are treated.
- Who signs off? Assign an accountable executive and have compliance review the submission before it goes in.
- What is the 2027 impact? Ask finance to model outreach lab revenue under 15% annual cuts on your top test codes.
