Context:

CMS unveiled 2027 rates for private Medicare plans, showing lower monthly costs for many beneficiaries as stand-alone Part D premiums edge up to about $36 on average, while Medicare Advantage premiums average around $12, down from 2026. The agency projects most enrollees can keep their current plans or move to cheaper options, with broad plan availability (roughly 97% of enrollees access 10 or more options). Insurers must notify enrollees by Sept. 30 of changes and enrollees can switch during open enrollment (Oct. 15–Dec. 7) for coverage starting Jan. 1, 2027. Experts caution some plans may trim drug formularies or raise cost sharing to curb costs underneath the hood. The update sits in a broader context of 2022 Inflation Reduction Act changes and the sunset of a Biden-era subsidy demonstration that supported low premiums.
