Who this affects: This bill mainly affects Medicare patients, ACOs, and primary care clinicians who are not doctors but often provide front-line care. Patients may be linked to the ACO that better matches the clinician they see most. ACOs may gain or lose assigned patients, which could affect how Medicare judges their cost and quality results.
Why this matters: Medicare may assign some patients to ACOs based on a picture of care that misses key primary care visits. This bill would add visits with nurse practitioners, physician assistants, and clinical nurse specialists to that picture. That could make ACO assignments more accurate. It could also change which ACO is judged for a patient’s care and costs, but the bill does not say what the final financial effect would be.
