# Medicare 2026 Guide: Parts A, B, C, and D Explained — Complete Enrollment Guide for Those Turning 65

> **Quick answer:** Medicare has four parts: Part A covers hospital stays (free for most people), Part B covers doctor visits and outpatient care ($185/month in 2026), Part C (Medicare Advantage) bundles everything through a private insurer, and Part D covers prescription drugs with a $2,100 annual out-of-pocket cap starting in 2026. You have a 7-month window to enroll around your 65th birthday. Miss it and you pay a permanent 10% penalty per year on Part B — forever.

Ten thousand Americans turn 65 every single day, and every one of them faces the same maze: four parts, multiple enrollment windows, permanent penalties for late signup, and a choice between two fundamentally different systems — Original Medicare and Medicare Advantage. The stakes are high. A wrong decision at 65 can cost you thousands per year for the rest of your life.

This Medicare 2026 guide explains Parts A, B, C, and D in plain English — exactly what each covers, what it costs in 2026, who qualifies, and when to sign up.
