This week, our In Focus section reviews two recent Medicare developments from the Centers for Medicare & Medicaid Services (CMS). On September 24, 2020, CMS released the Medicare Advantage (MA) and Part D landscape files for the 2021 plan year. These files include information on MA and Part D offerings, including plan types and premiums. Earlier this month, CMS also released a final rule implementing two new mandatory payment models addressing radiation oncology and end-stage renal disease (ESRD).
