Ambulatory Specialty Model (ASM) is CMS’s new mandatory specialty payment model for selected heart failure and low back pain specialists. Here’s who it affects, why it is different from traditional MIPS, and how provider organizations and EHR partners can prepare before the first performance year begins in 2027.

Some specialty providers recently opened a CMS notification and may have felt a little like they were staring at an old “Uncle Sam Wants You” poster. Only this time, the message is not coming from the Department of Defense. It is coming from CMS.

Selected specialists are being pulled into the Ambulatory Specialty Model, better known as ASM. No uniform required. No push-ups. No marching drills. But there will be reporting, outcomes tracking, care coordination, interoperability expectations, and the very real possibility of a significant negative Medicare payment adjustment.

For provider organizations, specialty groups, and EHRs supporting affected clinicians, ASM is not just another acronym to file away for later. It is a mandatory CMS model that begins in 2027, and preparation work must begin well before the first performance year.

CMS may not be handing you a helmet, but it is handing you a performance model.

What is ASM?

The Ambulatory Specialty Model (ASM) is a new mandatory CMS Innovation Center model focused on improving specialty care for Original Medicare beneficiaries with heart failure and low back pain.

ASM is intended to improve prevention, chronic disease management, patient outcomes, care coordination, and reduce avoidable hospitalizations and unnecessary procedures. The model begins on January 1, 2027, and runs for five performance years through December 31, 2031. Payment adjustments begin after performance is assessed and will affect future Medicare Part B payments.

For clinicians who want the official version, CMS provides an ASM Model Fact Sheet and related participant resources on its ASM model page.

Who got “drafted”?

CMS has made ASM mandatory for selected specialists in certain geographic areas who commonly treat Original Medicare patients for heart failure or low back pain in the outpatient setting.

The model initially focuses on general cardiology for heart failure and several specialties for low back pain, including anesthesiology, pain management, interventional pain management, neurosurgery, orthopedic surgery, physical medicine, and rehabilitation. To be included, clinicians must also have historically treated at least 20 heart failure or low back pain episodes per year, based on CMS’s episode-based cost measure methodology.

Based on current participant information from CMS, thousands of specialists have been identified for ASM participation, with the group made up of approximately 60% low back pain-related clinicians and 40% cardiology clinicians. For these clinicians, and for the organizations and EHRs that support them, ASM is no longer theoretical.

So yes, this is selective service - CMS style.

‍

Is ASM optional?

Not really.

That is the key point. ASM is not a traditional voluntary pilot where a practice can simply decide, “Thanks, but we’ll sit this one out.” If a clinician meets the CMS participation criteria and is included in the model, participation is mandatory.

CMS will assess performance and apply a positive, neutral, or negative payment adjustment to future Medicare Part B payments. In other words, affected clinicians are being placed into a model where quality, cost, care improvement, and interoperability performance can directly affect reimbursement from -9% to +9% and will increase in later payment years.

In simple words, this is a “participate and perform or risk the penalty” situation.

Why is ASM different from traditional MIPS?

Many clinicians are already familiar with MIPS. You see the patient, document the encounter, collect the quality data, report the measures, and hope the score keeps you safely away from the penalty zone.

ASM moves the conversation further upstream. CMS is looking beyond whether a measure was reported. ASM is intended to evaluate whether specialty care is improving outcomes, reducing avoidable utilization, coordinating with primary care, using certified technology, and managing patients more effectively over time.

CMS will evaluate ASM performance across multiple categories familiar to MIPS participants- Quality, Cost, Promoting Interoperability, and Improvement Activities.But ASM applies those concepts in a more focused specialty model tied to heart failure and low back pain.

That means provider organizations and their supporting EHRs may need to move from a “we reported the data” mindset to a more proactive “we can monitor, manage, and demonstrate better outcomes” approach.

That is a real operational shift. Like most operational shifts, it will be much easier to manage before the deadline, which is standing right outside the door, tapping its foot.

Why should organizations start preparing now?

ASM starts on January 1, 2027, but waiting until late 2026 to prepare would be like training for a marathon a week before.

Provider organizations will need time to identify affected clinicians, evaluate workflows, understand patient attribution, review Quality and Cost exposure, strengthen documentation, coordinate with primary care, address interoperability expectations, and build a strategy around patient outcomes.

EHR partners will also need to understand how ASM may affect their customers. Specialty groups will expect support with data capture, reporting workflows, dashboards, patient-reported outcomes, interoperability, and performance visibility. Those capabilities are hard to bolt on at the last minute.

Organizations that treat ASM as “just another MIPS program” may find themselves unpleasantly surprised. ASM is related to MIPS, but it is not simply MIPS with a new name tag. It is a specialty-focused, mandatory model with financial risk tied to performance.

CMS may have drafted selected specialists, but preparation is still the best defense.

Turning ASM readiness into an executable plan

ASM will not be managed successfully as a last-minute reporting project. It will require provider organizations and EHR partners to understand which clinicians are affected, how current MIPS and MVP workflows map to ASM expectations, and whether their data, documentation, interoperability, and performance monitoring processes are ready before the first performance year begins.

Darena Health’s MyMipsScore is built for this kind of transition. With more than nine years of CMS Qualified Registry experience, MyMipsScore helps EHRs and large provider organizations manage reporting path analysis, measure strategy, quality data acquisition, performance dashboards, improvement tracking, and CMS submission through a unified platform.

For provider organizations with ASM participants, that means clearer oversight across affected clinicians, locations, specialties, and performance categories. For EHR partners, it means a practical way to support customers facing ASM without building and maintaining every reporting, dashboard, certification, and submission-related capability in-house.

Darena Health can help teams:

Identify where ASM applies across clinicians, specialties, and practice operations
Review current MIPS, MVP, Quality, PI, IA, and documentation workflows
Assess data readiness for quality performance, care coordination, interoperability, and patient-reported outcomes
Monitor readiness and performance throughout the year with a user-friendly dashboard
Support the shift from traditional MIPS reporting to ASM-style performance management
Prepare provider organizations and EHR customers before the first ASM performance year begins

You’ve been drafted. Now what?

If your organization has ASM participants, or if your EHR supports customers who may be selected for ASM, this is not the time to file the notification away under “future CMS headaches.”

The work starts with understanding exposure, reviewing workflows, identifying data gaps, and putting the right performance visibility in place before ASM begins.

CMS may have drafted selected specialists into ASM, but provider organizations and EHRs still have time to prepare with a clear plan, the right infrastructure, and experienced support.
