The Centers for Medicare & Medicaid Services (“CMS”) recently finalized a rule establishing the new Ambulatory Specialty Model (“ASM”)— a mandatory value-based payment model that could apply to nearly one-quarter of all physicians in select specialties starting January 1, 2027. The ASM applies to physicians providing services to address two high-expenditure chronic conditions among Medicare patients: heart failure (cardiology) and low-back pain (pain management, interventional pain, neurosurgery, orthopedic surgery, and physical medicine and rehabilitation). Participation will be mandatory for eligible clinicians practicing in geographic areas selected by CMS that will likely encompass approximately one-quarter of U.S. Core-Based Statistical Areas (“CBSAs”) or metropolitan divisions nationwide. Published in connection with the Calendar Year (“CY”) 2026 Medicare Physician Fee Schedule (“PFS”), this alternative payment model represents a significant step in CMS’s transition toward specialty-specific accountability for cost, quality, and care coordination in ambulatory care. The model has significant implications for specialty practices, particularly those participating in or aspiring to join Accountable Care Organizations (“ACOs”). Additionally, the ASM will leverage components of the existing Merit-based Incentive Payment System (“MIPS”)/Medicare Value Pathways (“MVPs”) frameworks. For clinicians subject to MIPS/MVP, this model introduces a revised approach to performance scoring under a familiar framework.
