Roughly 40% of U.S. healthcare payments were tied to alternative payment models (APMs) last year, with Medicare Advantage claims representing the largest amount, a new survey found. The survey, published Wednesday by the Health Care Payment Learning & Action Network, showed that more work needs to be done as most healthcare payments were still tied to a fee-for-service model. Payers are also exploring how APMs can reduce health disparities, a major priority for the Biden administration and the Center for Medicare and Medicaid Innovation’s payment models going forward.
