Why start with the government's own book?
Everything written about Medicare traces back to this handbook. It is the source of record for what each part covers, how enrollment periods work, and what changes in the 2026 plan year — written by the agency that runs the program, with nothing to sell you.
We ask for your name and mobile number before the download so John knows who to follow up with — one quick text code, no password, no card. The same code opens every guide on this site.
