Medicare Part B: When Can You Sign Up?

🎬 Video ScriptEditorial Team•August 4, 2026

HOOK

Thinking you can sign up for Medicare Part B any time? Not always—and missing your window can mean a lifetime penalty. [On-screen: calendar pages flipping; close-up of Medicare card]

KEY POINT 1

Your first chance is your Initial Enrollment Period. It’s a 7-month window that starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after. [On-screen: simple 7-month timeline]

KEY POINT 2

If you’re still working and have health coverage through an active employer, you may qualify for a Special Enrollment Period later. That usually lets you sign up without a late penalty when your job coverage ends. [On-screen: person at work, then retiree leaving office]

KEY POINT 3

If you miss both windows, Medicare can charge a late enrollment penalty for Part B, and it can stick around as long as you have coverage. That’s why timing matters more than people think. [On-screen: warning icon next to bill statement]

KEY POINT 4

The safest move? Check whether you already have qualifying employer coverage, then mark your enrollment dates now. If you’re unsure, talk to Social Security or a Medicare counselor before your window closes. [On-screen: checklist being completed; phone call to counselor]
