Turning 65 in California: where to start
Understand the usual Medicare enrollment window and prepare your next questions.
When should I sign up around my 65th birthday?
Most people have a seven month Initial Enrollment Period: the three months before the month they turn 65, the birthday month, and the three months after. Coverage start dates depend on when the application is made. Missing the window can mean a delay and a late enrollment penalty. If you already receive Social Security, enrollment may be automatic; otherwise, sign up through Social Security.
I’m already 65 and missed enrollment. What now?
You may still have a path, depending on why you delayed and your current coverage. The General Enrollment Period for Part B and premium Part A is January 1–March 31. Premium-free Part A has different timing rules. A Special Enrollment Period may apply, including for qualifying coverage based on current employment. Gaps or late penalties are possible. Ask Social Security to confirm your exact enrollment path before changing coverage.
Three things to do next
- Check whether you are already enrolled.
- Confirm your individual dates with Social Security or Medicare.
- Write down your current coverage and when it ends.
