What Is the Ambulatory Specialty Model (ASM) Proposed by CMS?

In its 2026 Physician Fee Schedule Proposed Rule, the Centers for Medicare and Medicaid Services (CMS) proposed a new mandatory payment model–titled the Ambulatory Specialty Model (ASM)–for specialists who treat congestive heart failure (CHF) and low back pain. With the reported aim of driving better outcomes, improving chronic disease management, and reducing unnecessary costs for Medicare, the ASM is expected to take effect on January 1, 2027, running for five performance years through December 31, 2031. Read the full ASM proposal in the federal register.

For affected specialists in mandated core-based statistical areas (CBSAs), including orthopedic surgeons, neurosurgeons, cardiologists, and others, the ASM would represent a major shift. It calls for specialists to take on new accountability, join in tighter coordination with primary care, and embrace transparency in cost, quality, and data sharing.

Ambulatory Specialty Model Key Goals

The ASM is focused specifically on specialists who treat CHF and low back pain among Original Medicare beneficiaries in outpatient settings. The model is designed to address systemic gaps in how chronic conditions are detected, treated, and managed, with CHF and low back pain representing common conditions with high potential for substantial cost savings for Medicare.

The model’s goals include promoting prevention and earlier detection of chronic disease to avoid costly downstream complications arising from worsening and recurring chronic conditions, improving chronic disease management through increased collaboration between specialists and primary care providers, enhancing the patient experience by prioritizing patient-reported outcomes (PROs) on function, and reducing avoidable hospitalizations and treatments that are not backed by clear evidence.

Performance Measures

The ASM measures performance on the clinician level, rather than aggregating performance across systems or practices. The model borrows from existing CMS value-models (especially MIPS Value Pathways) but adds specific conditions, risk structure, and reporting requirements, as shown below:

Feature What ASM Proposes
Eligible Specialties Cardiologists treating heart failure, as well as anesthesiologists, pain management specialists, neurosurgeons, orthopedic surgeons, physical medicine and rehab clinicians treating low back pain.
Minimum Volume Requirement Must have historically treated at least 20 episodes over a 12 month period for the specified condition via their specialty to be eligible.
Geographic Scope Participation is mandatory in selected Core-Based Statistical Areas (CBSAs), not nation-wide. CMS notes that roughly 25% of all CBSAs will be included in the model, and this list will be released by the end of 2025.
Performance Period 2027 through 2031 (five performance years), affecting payment 2 years later (i.e. performance year 2027 affects payment year 2029).
Payment Adjustments Two-sided risk: With Part B reimbursements at risk, specialists may earn positive adjustments (bonuses), stay neutral, or incur negative adjustments. The model starts with 9% of reimbursements at risk, rising to 12% by the end of the model duration.

Importantly, payment adjustments will be reliant on individual clinician performance relative to other clinicians, with scoring being weighted based on quality and cost.
Performance Categories Performance will be measured as a composite score based on four domains:
  • Quality, such as by improving functional outcomes for low back pain.
  • Cost, such as by reducing unnecessary/harmful care or overuse of care resources.
  • Improvement Activities, including patient engagement and screening for health-related social needs.
  • Interoperability, specifically by using certified electronic health record tech (CEHRT) to share data and coordinate care.
Proposed Quality Measures (excluding other measures under consideration) Heart Failure:
  • Risk-standardized acute unplanned cardiovascular-related admission rates for patients with heart failure (HF)
  • Heart Failure: Beta-blocker therapy for left ventricular systolic dysfunction (LVSD)
  • Heart Failure: Angiotensin-converting enzyme (ACE) inhibitor or angiotensin receptor blocker (ARB) or angiotensin receptor-neprilysin inhibitor (ARNI) therapy for LVSD
  • Controlling high blood pressure
  • Functional status assessments for heart failure
Low Back Pain:
  • Magnetic resonance imaging (MRI) lumbar spine for low back pain, respecified to be relevant to ASM participants treating low back pain
  • Use of high-risk medications in older adults
  • Preventive care and screening: screening for depression and follow-up plan
  • Preventive care and screening: body mass index (BMI) screening and follow-up plan
  • Functional status change for patients with low back impairments
Note: additional measures are also under consideration and can be viewed here.
Provider Comparison / Transparency Specialists will be benchmarked against peers in the same specialty and region; data will be made available to promote competition between clinicians and reward high-performing participants.

Risks and Opportunities

The ASM is ambitious, targeting some of the costliest chronic conditions in Medicare and asking specialists to engage in upstream work, not just procedural or consultative work.

Risks

  • Financial exposure: specialists must have strong cost control (e.g. against unnecessary imaging, over-referral, avoidable hospitalizations) to avoid low scores on the cost performance measures.
  • Reporting burden: specialists will need to track and report outcomes, cost, and interoperability metrics, and possibly participate in new collaborative care workflows. Added reporting burdens on clinicians can sacrifice time that can be dedicated to patient care, increase costs for clinicians, and increase burnout.
  • Infrastructure gaps: many specialty clinics may not currently have CEHRT or systems for data sharing or care coordination with primary care. Finding a solution to ensure this requirement is fulfilled should be a comprehensive process to ensure suitable fit, so as to avoid downstream costs and technical complications.
  • Behavior change challenge: moving from volume-driven care to value-driven care will require changes in clinical practice, referral patterns, and clinical workflows. Implementing such changes can be a time-consuming process that distracts time away from direct patient care.

Opportunities

  • Improved patient outcomes through earlier intervention, better chronic disease control, and fewer complications.
  • Cost savings both for providers and for Medicare, especially by reducing avoidable hospitalizations and low-value procedures.
  • Competitive advantage for high performers, especially in regions where transparency and peer comparisons become more visible.
  • Enhanced patient satisfaction by emphasizing care experience, function, and patient priorities.

What Specialists Should Do Now

To get ahead of ASM, health systems and specialty care providers should begin preparing immediately by following these recommendations:

  1. Assess current data capabilities for tracking cost, patient outcomes, and required performance metrics
  2. Identify and close gaps in coordination with primary care
  3. Review current performance on target conditions and metrics
  4. Pilot patient engagement, outcome tracking, and education tools
  5. Build reporting & analytics capacity
  6. Monitor updates from CMS regarding mandatory CBSAs and other details
