The Ambulatory Specialty Model (ASM): What Cardiologists Need to Know Now

The healthcare reimbursement landscape continues to evolve, and one of the most significant changes on the horizon for cardiology practices is the Centers for Medicare & Medicaid Services (CMS) Ambulatory Specialty Model (ASM). While the program does not officially begin until January 1, 2027, practices should start preparing now to understand how it may impact patient care, quality reporting, and reimbursement.

ASM is a mandatory value-based payment model that will hold participating cardiologists financially accountable for the management of heart failure patients. Under the model, physicians in selected geographic regions will receive positive or negative adjustments to all Medicare Part B payments based on their performance in key quality and cost measures. Those adjustments begin at 9% and increase to as much as 12% over the course of the program.

For cardiology practices, the challenge is clear: success will depend on more than what happens during office visits. CMS will evaluate providers on measures that include unplanned cardiovascular hospital admissions, blood pressure control, guideline-directed medical therapy, and functional status assessments for heart failure patients. In addition, total healthcare spending associated with heart failure episodes will play a significant role in determining performance. Missing documentation, gaps in patient monitoring, or avoidable hospitalizations can negatively affect both quality scores and financial outcomes.

One of the most important themes emerging from ASM is the growing need for connected patient engagement between office visits. Traditional episodic care models often leave providers unaware of worsening symptoms until a patient presents to the emergency department or requires hospitalization. Under ASM, those events may directly impact performance scores and reimbursement.

This is where remote patient monitoring (RPM), heart failure monitoring, and ongoing patient engagement programs can become valuable tools. CMS has made it clear that providers will need reliable ways to collect blood pressure readings, weight measurements, medication adherence information, and other clinical data outside the office setting. Connected care monitoring can help identify changes in a patient’s condition earlier, allowing clinicians to intervene before a hospitalization becomes necessary. 

At Cardiac RMS, we have been helping cardiology practices implement exactly these types of workflows for years. Through our remote patient monitoring, heart failure monitoring, device monitoring, remote nursing services, and patient engagement services, we help practices maintain consistent touchpoints with patients, improve compliance, capture critical clinical data, and support proactive interventions. These capabilities align closely with many of the goals CMS is emphasizing through ASM.

While many details will continue to evolve as CMS finalizes implementation, one thing is already becoming clear: the future of heart failure management will depend increasingly on connected care, actionable patient data, and coordinated interventions rather than relying solely on periodic office visits.

Over the coming months, Cardiac RMS will continue monitoring ASM developments and sharing practical guidance to help our clients and partners understand what these changes mean for their practices. As always, our goal is to help cardiology teams stay informed, prepared, and positioned for success in an increasingly value-based healthcare environment.
