On September 5, 2023, the Centers for Medicare & Medicaid Services (CMS) announced a new voluntary, state total cost of care (TCOC) model: the States Advancing All-Payer Health Equity Approaches and Development Model (“States Advancing AHEAD” or “AHEAD” Model). CMS’s goal in the AHEAD Model is to collaborate with states to curb health care cost growth, improve population health, and promote healthier living.
