Calendar Year (CY) 2026 Physician Fee Schedule (PFS) Proposed Rule 

CMS issued the CY 2026 PFS proposed rule that announces the proposed policy changes for Medicare payments under the PFS and other Medicare Part B payment policy issues including ambulance services. Section 2203 of the Full-Year Continuing Appropriations and Extensions Act, 2025 (Pub. L. 119-4, March 15, 2025) extended three existing add-on payments to the ambulance base and mileage rates under the Ambulance Fee Schedule for ground ambulance transports through September 30, 2025.  Accordingly, CMS is proposing to revise our regulations at 42 CFR §414.610(c)(1)(ii) and 414.610(c)(5)(ii) in this proposed rule to align with existing law. CMS will accept comments on the proposed rule until September 12, 2025 and will respond to comments in a final rule.
