On November 4, 2026, the Centers for Medicare and Medicaid Services (CMS) released the Calendar Year 2027 Medicare Physician Fee Schedule final rule. The conversion factor for non-qualifying providers is $32.63, down $0.77 or 2.31% from $33.40. The factor for qualifying alternative payment model participants is $32.95, down 1.83% from $33.57. Both cuts are deeper than July’s proposal, which set $32.84 (a 1.68% cut) and $33.17 (1.19%), as we covered in the proposal piece. Measured against the proposed factor, the final non-qualifying figure is another 0.64% lower. The rule takes effect for services on or after January 1, 2027.
What changed, and what did not
CMS attributes the cut mainly to the expiry of the one-year 2.50% increase Congress granted for 2026 under Public Law 119-21. Statutory updates of 0.25% (non-qualifying) or 0.75% (qualifying) and an estimated -0.12% work relative value unit adjustment partly offset it. The rule also phases out the indirect practice cost index over two years and changes how indirect practice expense is allocated. That redistributes payment between specialties, so the conversion factor is not the whole price change for any given billing code.
Who it affects
Self-insured employers and workers’ compensation captives with physician-heavy medical spend (orthopedic, occupational medicine, physical therapy) in states that price fee-schedule services as a multiple of the Medicare allowable. Employers in states with fixed-dollar schedules or no schedule see no direct effect.
The reserve mechanism
The lever is medical severity per service, not frequency. The July analysis said to wait for the final rule; it is now in hand, and the next step is state-specific. Three update mechanics decide the outcome:
- Fixed-dollar schedules ignore the Medicare change until the state board rewrites its own table. Pass-through for 2027 service dates is zero.
- Percent-of-Medicare schedules that adopt the current-year factor move with it. A schedule at a fixed multiple of Medicare would, all else equal, fall by about the same 2.31% on affected codes.
- Lagged or frozen-base schedules update on a delay or reference an older Medicare year, so the saving arrives late or never.
The savings then have to survive utilization. WCRI’s work on services outside fee schedules shows price control covers only part of medical spend, and our look at the physician price gap shows schedules already differ widely by state. A cut on scheduled codes does nothing to the unscheduled remainder.
There is a second effect that is easy to miss. Open claims carry future medical in case reserves, often at the price level an adjuster saw when setting them. If a state passes the cut through, those reserves may be modestly redundant on scheduled services. If it does not, nothing is redundant, and crediting a saving would understate the reserve.
Where this shows up in your reserves
Open your actuary’s medical paid triangle for indemnity-and-medical split claims and look at paid medical per claim by service date, separated by state. Then check the severity trend selection for the 2027 accident year: a mechanical fee credit belongs only in states with confirmed adoption. Case adequacy shows up in the future-medical component of open-claim case reserves, which the triangle does not isolate unless your TPA data extract does.
Our read
Expect little 2027 paid-medical relief in aggregate. The cut is real only where a state adopts the 2027 factor on a percent-of-Medicare basis, and many state agencies act after January 1, so first-half 2027 service dates may pay at old rates and be corrected later. Because the final cut exceeded the proposal, a 2027 trend selection that was built on the July figure is now about 0.6 points stale in adopting states. That is a small number against a medical trend that NCCI and WCRI data show is driven by other components. Our directional view: treat any 2027 fee schedule credit as a timing item that reverses less often than it confirms, and hold future-medical case reserves unchanged until the state adopts.
What this means for your next review
Put a state-by-state adoption table on the agenda, listing each exposure state, its Medicare linkage type, and its 2027 effective date. Ask that any severity credit be booked only for states in that table with confirmed adoption. See also the workers’ compensation IBNR explainer and the case reserve strengthening explainer.
Decision-maker checklist
- List every state where you have open WC claims and tag each as fixed-dollar, percent-of-Medicare, or lagged.
- Ask your actuary how the 2027 medical severity trend separates price from utilization, and which states carry a fee credit.
- Confirm your TPA extract can show paid medical per claim by state and service date for the first quarter of 2027.
- Check whether future-medical case reserves on large open claims are carried at current prices, and document the basis either way.
- Watch state agency bulletins for adoption of the 2027 factors, and revisit the trend selection when they arrive.
