Medicare Open Enrollment Starts October 15

September 21, 2026

Did you know your Medicare plan can change for next year even if you don't touch a thing?

📬 Each fall, Medicare Advantage and Part D plans send a letter called the Annual Notice of Change.

It arrives by September 30 and outlines what's different starting January 1: premiums, copays, network doctors, and covered medications.

Most people never open it. A large share of Medicare beneficiaries never compare their options.

Open Enrollment runs October 15 through December 7. Take the time to note what is changing for the coming year.
