The short answer

Most people enroll in Medicare through Social Security, either online at SSA.gov, by calling 1-800-772-1213, or by visiting a local Social Security office. The right time to enroll depends on your age and whether you have other coverage.

The full explanation

If you're already receiving Social Security benefits when you turn 65, you'll usually be enrolled in Medicare Parts A and B automatically. You'll receive your red, white, and blue Medicare card in the mail a few months before your 65th birthday.If you're not yet receiving Social Security, you need to sign up yourself. The easiest way is online at SSA.gov. You can also call Social Security at 1-800-772-1213 or visit a local office. Your Initial Enrollment Period is a seven-month window, starting three months before the month you turn 65 and ending three months after.If you're still working at 65 and covered by an employer health plan, you may be able to delay Part B without a penalty. Whether that makes sense depends on the size of your employer and how your current coverage works. Getting this wrong can lead to a permanent late enrollment penalty on your monthly premium, so it's worth talking through your specific situation before you decide.Once you have Parts A and B, you can choose to add a Medicare Advantage plan or a standalone Part D drug plan through a private insurance carrier. Those enrollments happen separately, through the insurance company or Medicare.gov.Timelines and rules vary based on your situation, so confirm the details with Social Security or a licensed Medicare counselor before you act.
