Turning 65
Your Medicare Journey Starts at 65
Turning 65 brings a lot of mail, a lot of opinions, and a lot of unfamiliar terms. Here's the plain-English version of what actually matters and when.
Quick Answer
You have a 7-month window around your 65th birthday to enroll in Medicare without a penalty. During that window you'll decide on Part A, Part B, and whether to add a Medicare Advantage plan, a Medigap policy, and/or a Part D drug plan.
Your 7-Month Window to Enroll
This window is called your Initial Enrollment Period (IEP). It starts 3 months before the month you turn 65, includes your birthday month, and runs 3 months after — 7 months total. Enrolling in the 3 months before your birthday month usually means your coverage starts the first day of your birthday month. Wait until later in the window, and your start date gets pushed back.
3 Decisions You'll Make at 65
1. Part A
Hospital insurance. Most people qualify for it premium-free based on work history, and most people enroll as soon as they're eligible.
2. Part B
Medical insurance for doctor visits and outpatient care. Carries a monthly premium — if you're still working with employer coverage, you may be able to delay it.
3. What Comes Next
Once you have Parts A and B, you choose how to fill the gaps: a Medicare Advantage plan, a Medigap policy plus Part D, or Original Medicare alone.

What Happens If You Miss Your Window
If you don't have other qualifying coverage (like an active employer plan) and you miss your Initial Enrollment Period, two things can happen. First, you may have to wait for the next enrollment period to sign up, leaving a gap with no coverage. Second, you may owe alate enrollment penalty — for Part B, that's typically an extra 10% of the standard premium for each full 12-month period you were eligible but didn't enroll, and it generally lasts as long as you have Medicare. A Part D late enrollment penalty works similarly for drug coverage. See how late enrollment penalties workfor the full picture.

Frequently Asked Questions
When does my Medicare Initial Enrollment Period start?
Your Initial Enrollment Period is 7 months long: it starts 3 months before the month you turn 65, includes your birthday month, and ends 3 months after.
Do I have to sign up for Medicare at 65 if I'm still working?
Not always. If you have qualifying coverage through a current employer (usually one with 20 or more employees), you may be able to delay Part B without a penalty. If your coverage is through a smaller employer or retiree plan, the rules differ, so it's worth checking your specific situation before your window closes.
What's the difference between Part A and Part B?
Part A covers hospital stays, skilled nursing facility care, and hospice. Part B covers doctor visits, outpatient care, and preventive services. Most people get Part A premium-free but pay a monthly premium for Part B.
What happens if I miss my Initial Enrollment Period?
If you don't have other qualifying coverage and miss your window, you may face a late enrollment penalty added to your Part B premium for as long as you have Medicare, plus a gap in coverage until the next enrollment period opens.
