CMS's ACCESS (Advancing Chronic Care with Effective, Scalable Solutions) model is a 10-year voluntary national trial of results-based payments in Original Medicare, starting July 1, 2026, and ending June 30, 2036.[1][2] It focuses on chronic conditions affecting more than two-thirds of Medicare beneficiaries, such as hypertension, diabetes, chronic kidney disease, obesity, chronic pain, depression, and anxiety.[1][2] Enrollees who must be enrolled in Medicare Part B receive outcome-based payments (OAPs) based on improvements in patient health in addition to standard fee-for-service.[1][6] CMS will begin accepting applications on January 12, 2026, with the first due date on April 1, 2026, and additional cohorts on a rolling basis through 2033.[1][2] Original Medicare patients can enroll directly or be referred by a physician, with CMS posting a public list of enrollees with results.[2][6] Referring clinicians receive approximately $30 for the service plus a one-time $10 onboarding bonus.[6] The model coincides with the exit of major insurance companies from Medicare Advantage, where the largest insurer plans to drop about 1 million seniors by 2026.[1]
