At a recent event in Washington, DC, commemorating the 50th anniversary of Medicare and Medicaid, Andy Slavitt, acting administrator of the Centers for Medicare & Medicaid Services (CMS), discussed a recent visit to On Lok Lifeways in San Francisco. "On Lok [is] part of a very important program called PACE," Slavitt said. "Places like On Lok really impress me. When I visit them, I feel like I'm glimpsing very much into our future."
