Medicare 2027 Changes: What Katy, Dallas, San Antonio & Oklahoma City Members Should Review

Medicare Annual Enrollment runs October 15 through December 7. Changes you make take effect January 1. Every fall your plan sends an Annual Notice of Change — read it, because premiums, copays, drug lists and provider networks can all change.

For Medicare Advantage members, confirm your doctors and hospitals are still in network and review changes to extra benefits like dental and vision. For Part D members, check that each of your prescriptions is still on the drug list and in the same tier.

We compared the year-over-year changes in detail: Medicare Advantage 2026 vs 2027 and Part D 2026 vs 2027.
