ASM (Ambulatory Specialty Model)

ASM (Ambulatory Specialty Model) Updates Proposed

Updates to ASM were proposed in the 2027 Physician Fee Schedule Notice of Proposed Rulemaking on July 14, 2026. Comments are due by 11:59 PM on September 14, 2026.

The Ambulatory Specialty Model (ASM) aims to improve upstream management of chronic disease to reduce avoidable hospitalizations and unnecessary procedures in Original Medicare. It tests whether performance-based payment adjustments for select specialists who care for beneficiaries with heart failure or low back pain will encourage stronger care coordination and chronic disease management.

ASM is a mandatory model with five performance years that run from January 1, 2027, through December 31, 2031.

Key Points
  • Problem: People with chronic conditions often see multiple, unconnected clinicians, which can lead to fragmented care, delayed diagnoses and treatment, unnecessary procedures and hospitalization, and poor health outcomes.
  • Solution: ASM will promote preventive care and more effective upstream chronic disease management by rewarding ASM participants that are heart failure and low back pain specialists for improving patient health outcomes and coordinating with primary care providers.
  • Outcomes: Successful outcomes include reducing avoidable hospitalizations and unnecessary procedures, improving patient experience, and lowering costs to Original Medicare.  
  • Strategy: ASM will help to achieve President Trump’s directive to Make America Healthy Again by promoting preventive care through screenings, increasing transparency by making medical provider performance data more widely available, and protecting American taxpayers by holding select specialists accountable for the cost and quality of care they deliver.
