If you've been hearing more about the Ambulatory Specialty Model (ASM) lately and aren't totally sure what to make of it, you're not alone. It's a lot of acronyms for what is, at its core, a significant shift in how the Centers for Medicare & Medicaid Services (CMS) approaches cardiology reimbursement.
Here's the short version: ASM is a new mandatory CMS program starting January 1, 2027, and for cardiology practices treating Original Medicare patients with heart failure, participation isn't a choice. Performance gets measured. Payment adjustments — positive or negative — follow.
The good news? There's still time to get in front of it. Let's walk through what you actually need to know.
The Ambulatory Specialty Model (ASM) is a CMS Innovation Center program focused on improving specialty care for Original Medicare patients with heart failure and low back pain. For cardiology, the heart failure track is the one to pay attention to.
ASM runs five performance years, from January 1, 2027 through December 31, 2031, with payment adjustments applied during the payment years running January 1, 2028 through December 31, 2033. CMS evaluates performance across four categories, Quality, Cost, Promoting Interoperability, and Improvement Activities, and adjusts future Medicare Part B payments accordingly.
Payment adjustments range from -9% to +9% in the first two payment years (2028 and 2029), and that range increases in later payment years. To make it concrete: the final score a practice earns for the 2027 performance year will directly determine the payment adjustment applied to their 2029 Part B covered professional service claims.
Each ASM participant, at the individual Tax Identification Number (TIN)/National Provider Identifier (NPI) level, receives their own final score and payment adjustment. This isn't a group average. It's individual accountability.
And here's what makes the stakes particularly significant: those adjustments apply to all Part B covered professional service payments, not just claims tied to heart failure treatment. Underperformance under ASM affects the practice's entire Medicare Part B revenue, not just the cardiology portion.
Worth noting: heart failure practices are already contending with Hospital Readmissions Reduction Program (HRRP) penalties, up to 3% of total Medicare payments for excess readmissions. ASM is a separate, additional layer on top of that.
Yes, effectively. ASM participants are exempt from Merit-based Incentive Payment System (MIPS) reporting requirements during ASM performance years. That means the familiar MIPS cycle — report, submit, stay out of penalty territory — no longer applies to affected cardiologists. ASM is the performance model now, and it's built around outcomes rather than reporting.
That's a meaningful shift. MIPS rewards documentation. ASM rewards results.
ASM starts January 2027. See how PATHS helps cardiology practices build the patient engagement and documentation infrastructure the model requires. Book a 30-minute demo → www.villagepaths.com
PATHS is a digital care platform built on a simple idea: what happens between clinical visits matters just as much as what happens during them. For heart failure patients — and for practices navigating ASM — that idea has very practical implications.
Here's how PATHS supports the kind of care ASM rewards:
Keeping patients engaged between visits: PATHS delivers structured, step-by-step education to heart failure patients outside the clinical setting — warning signs, medication adherence, daily monitoring, when to call the office. The goal isn't just information delivery. It's building the kind of continuous connection that supports better outcomes and gives your team visibility into how patients are doing before a problem becomes an emergency room (ER) visit.
Documentation that supports care management workflows. One of the quieter challenges in ASM is proving that care coordination happened — not just that it was planned. PATHS creates a timestamped record of patient engagement activities and educational interactions that may help practices document patient participation and support care management workflows. For practices performing Chronic Care Management (CCM), Transitional Care Management (TCM), or Advanced Primary Care Management (APCM) services, these records may complement existing clinical documentation processes — though practices remain responsible for ensuring all CMS billing requirements are met, including clinician oversight, required service elements, patient consent, and appropriate documentation within the medical record.
24/7 access for patients who need it most. Post-discharge is one of the highest-risk windows for heart failure patients, and a major driver of the 30-day readmissions that both HRRP and ASM penalize. PATHS keeps patients connected to their care plan around the clock — so the support doesn't stop when they leave the building.
Real-time visibility for your care team. You can't intervene on what you can't see. PATHS gives your clinical and administrative team a live view of patient engagement, care plan progress, and completion rates across your population — so you can catch patients who are falling behind before it becomes a bigger problem.
Works with your existing Electronic Health Record (EHR). PATHS integrates with existing EHR systems. Adding a patient engagement layer doesn't mean replacing what you've already built — it means getting more out of it.
January 2027 feels far away. It isn't, once you account for everything that needs to happen first.
Identifying affected clinicians, updating care coordination workflows, building post-discharge follow-up processes, getting documentation in order for CCM and TCM billing — that's months of work, not weeks. Trying to do it simultaneously with the first performance year is a tough position to be in.
The practices that will perform well under ASM aren't the ones scrambling in late 2026. They're the ones building the right habits and infrastructure now — and capturing the reimbursement upside in the meantime.
Say a cardiology practice has 500 heart failure patients entering the first ASM performance year. With PATHS:
Those aren't aspirational capabilities. That's what PATHS does today.
ASM doesn't require a technology overhaul. It requires the right infrastructure — patient engagement, documentation, and outcome visibility — in place before the model demands it.
PATHS is built for exactly that.

2027 is coming. Let's make sure your practice is ready for it.
Compliance Note: PATHS is an education and engagement platform and does not independently generate billable Medicare services. Practices remain responsible for determining patient eligibility, obtaining required consents, performing and documenting all required clinical services, and ensuring compliance with CMS billing requirements and applicable federal and state regulations.
