2026 Medicare Reimbursement Changes: What the Conversion Factor Update Really Means
Medicare reimbursement remains below the cost of delivering care for 80% of medical groups in 2026, according to an MGMA Stat poll of 166 respondents. CMS set the 2026 Physician Fee Schedule conversion factor at $33.57 for Advanced APM participants and $33.40 for non-participants — increases of 3.77% and 3.26% respectively after years of flat or negative updates. However, a new -2.5% efficiency adjustment on work RVUs for non–time-based services may offset gains at the service-line level for procedural specialties. Telehealth flexibilities are extended through December 2027. Medicare Advantage denial strain — from prior authorization, downcoding, and narrow networks — compounds the squeeze, with total operating cost per FTE physician rising 63% from 2013 to 2022 while the conversion factor grew just 1.7% over the same period.
Practices that rely on commercial rates to subsidize Medicare shortfalls need to model 2026 impacts by service line now — not at year-end. The RVU efficiency adjustment and MA denial dynamics hit procedural and specialty groups hardest, and administrative burden is rising faster than any rate increase can offset.

What is the 2026 Medicare Physician Fee Schedule conversion factor?
The 2026 conversion factor is $33.40 for non-Advanced APM participants (a 3.26% increase) and $33.57 for qualifying Advanced APM participants (a 3.77% increase). Despite these gains, total operating cost per FTE physician rose 63% from 2013 to 2022 while the conversion factor grew only 1.7%, meaning the 2026 increase narrows but does not close the structural reimbursement gap.
How does the 2026 RVU efficiency adjustment affect medical practice revenue?
CMS finalized a -2.5% efficiency adjustment applied to work RVUs for many non–time-based services, using a five-year lookback of the Medicare Economic Index productivity adjustment. Practices heavily reliant on procedural or non–time-based codes may see their effective payments reduced despite the higher conversion factor. Administrators should model code-level impacts across their top billed services to identify where margins are most exposed.
What are the biggest threats to Medicare payment yield for medical groups in 2026?
Medicare Advantage denial rates — driven by prior authorization, downcoding, and narrow networks — reduce effective reimbursement even as fee schedule rates improve, with 80% of medical groups reporting Medicare rates still below the cost of delivering care. Rising administrative burden from MA plans compounds this pressure. MGMA recommends tracking denied claims and downcoded services by payer to identify patterns that can support contract renegotiation or appeals.
