In regulations published on April 16, 2018, the Centers for Medicare & Medicaid Services (CMS) issued two new documents containing guidance primarily on the Medicare Advantage (MA) program and on the Medicare prescription drug benefit program. Taken together, these two documents – a finalized regulation outlining policy changes for Contract Year 2019 (Final Rule) and a 2019 Rate Announcement and Final Call Letter (Final Call Letter) – represent further steps by the Trump administration to reduce regulatory obstacles to better healthcare delivery, to address prescription drug issues, and to improve choices available to Medicare parts C and D plan enrollees. These Final Rules, with limited exceptions, will be applicable January 1, 2019.
