What Do You Need to Do When You Turn 65 for Medicare?
When you turn 65, you need to decide whether to enroll in Medicare—and if so, which parts to choose and when to enroll.
The exact steps depend on:
Whether you’re still working
Your current health insurance
Your future plans
Taking the right steps at 65 helps you avoid penalties, prevent coverage gaps, and control your healthcare costs.
👉 Start here: What Happens When You Turn 65?
Step 1: Understand Your Enrollment Window
Most people have a 7-month Initial Enrollment Period (IEP):
3 months before your 65th birthday
Your birthday month
3 months after
Enrolling during this window helps you avoid:
Late enrollment penalties
Delayed coverage

Alternative to Original Medicare
Bundles coverage into one plan

Helps cover medications

Are your premiums higher or lower than Medicare?
