Heart Failure Accountability Moves to the Cardiologist: What ASM Asks of You in 2027
Published by APM Connect 10/30/2026
For more than a decade, the financial consequence of a heart failure readmission landed on the hospital. The Hospital Readmissions Reduction Program never reached the outpatient cardiologist managing that patient in the months between admissions, and that gap is what the Ambulatory Specialty Model is built to close. Starting January 2027, accountability attaches to the individual cardiologist at the NPI level. This session covered what the model actually asks for, and then the clinical question underneath it: why so many heart failure admissions happen at all.
WHAT WE COVERED
ASM replaces MIPS for the cardiologists selected into it, and selection is not optional. If you're on the CMS participation list, you are mandated in the model. Current participation in an ACO does not shield you.
The scoring is individual and graded on a curve. Quality and cost each carry half the score, measured at the NPI level and compared against your peers rather than against a fixed threshold. The Improvement Activities and Promoting Interoperability categories do not boost your score; failure to attest to these two categories only brings you down.
A cardiologist's average episode cost will be measured differently than the hospital models. A patient's heart failure episode is opened when there is an an outpatient visit with a heart failure diagnosis plus a second qualifying claim within 180 days, and the measurement window runs from 365 up to 729 days. Any service related to the treatment of heart failure within the measurement window will be counted toward the episode's cost.
A physician's final composite score in ASM will determine a future Part B adjustment two years after the performance year. The adjustment applies to all of your Part B billings. The maximum penalty is 9 percent for 2027 and 2028 but climbs to 12 percent in 2029. The maximum upside adjustment is lower because CMS redistributes only 85 percent of the pool and keeps the rest, which is how the model guarantees savings rather than simply moving money between clinicians.
On the clinical side, the case for prevention is mostly about fluid. Around three quarters of heart failure costs come from the hospitalization itself, and the great majority of those admissions trace to fluid overload. Dr. John Mohr walked through the mechanism that makes this hard: during worsening symptoms, venous congestion and gastrointestinal mucosal edema reduce absorption of oral loop diuretics, so the drug is least available at the moment the patient needs it most. Guideline options when that happens are a higher oral dose, intravenous diuretics, or adding a thiazide, with the guidelines favoring optimizing the loop diuretic first.
