Medicare’s annual open enrollment period begins for beneficiaries, allowing people to review and change their coverage. The period runs until Dec. 7, and during that time enrollees can switch between traditional Medicare and Medicare Advantage plans, depending on what options are available to them.

Several outlets report that the changes most notably take effect in 2027. These include higher out-of-pocket maximums and the end of temporary federal subsidies for Part D premiums, which some beneficiaries currently benefit from. The reported changes arrive amid broader financial pressure on seniors, as inflation contributes to rising healthcare costs, and they coincide with political attention on cost-of-living issues ahead of upcoming elections.

While coverage focuses on what beneficiaries need to do during open enrollment, the sources broadly agree on the timeline and on the main 2027 adjustments—especially impacts to out-of-pocket spending and Part D premium support—though they emphasize different aspects of those updates.
