CMS (the Centers for Medicare & Medicaid Services) has issued a proposed rule for calendar year 2027 that would update how Medicare pays for many services under Part B. The proposal covers changes to the Physician Fee Schedule (PFS) and other Part B payment policies meant to keep payment systems aligned with changes in medical practice and federal law.
The proposed rule also would “codify” (put into the regulations) new or updated policies tied to recent federal legislation. That includes rules for the Medicare Prescription Drug Inflation Rebate Program created under the Inflation Reduction Act of 2022, along with provisions from the Consolidated Appropriations Act, 2026.
In addition, CMS proposes updates affecting specific Medicare programs and provider types, including the Medicare Shared Savings Program requirements, the Quality Payment Program, and payment policies for Rural Health Clinics and Federally Qualified Health Centers. The proposal also includes updates to the Ambulance Fee Schedule and the Medicare Promoting Interoperability Program.
CMS further proposes updates to how certain drugs and biological products are paid under Part B, and updates to Clinical Laboratory Fee Schedule regulations. Because this is a proposed rule, the final details could change after public comment.
