Turning 65 and Medicare
Know when to apply for Parts A and B, how employer coverage affects your timing, and when to compare Medicare Supplement, Medicare Advantage and Part D.
Your first enrollment window
For most people becoming eligible at 65, the window begins three months before the month they turn 65 and continues for three months afterward. Starting early helps prevent rushed decisions and coverage gaps.
Confirm whether you need to enroll and compare your coverage choices.
Your exact coverage start depends on when you enroll and your situation.
Waiting can delay coverage, so understand your effective date before applying.
Working at 65
Do not assume that every employer plan works the same way with Medicare. Confirm who pays first and whether delaying Part B is appropriate.
Retiring or losing active coverage
Apply early enough for Parts A and B to begin when your current coverage ends, then select the additional Medicare coverage that fits your needs.
Continuing to work
Coverage based on current employment may allow you to delay Part B, but employer size, plan coordination and HSA considerations can affect the decision.
Your 8-month Part B Special Enrollment Period generally begins when employment or active-employment group coverage ends—even if you choose COBRA. Confirm your dates before delaying Medicare.
A simple checklist
Review your 65th birthday, retirement date and any health coverage based on your or your spouse’s current employment.
If you need to enroll, apply through Social Security and choose effective dates that coordinate with your existing coverage.
Have your Medicare number and effective dates, doctors, prescriptions, pharmacy and travel needs ready for comparison.
Compare Original Medicare with Medigap and Part D against Medicare Advantage before your new coverage begins.

Know the deadlines
Different parts of Medicare follow different clocks. Your personal timeline depends on your birthday, employment coverage and effective dates.
Generally begins 3 months before the month you turn 65, includes your birthday month and ends 3 months afterward.
Generally available after your or your spouse’s active employment—or coverage based on that employment—ends, whichever happens first.
A one-time federal period that starts the first month you are 65 or older and enrolled in Medicare Part B.
Going 63 days or more without Part D or other creditable prescription coverage may lead to a late enrollment penalty.
After Parts A and B
Both paths provide Medicare coverage, but provider access, costs, drug coverage and plan rules work differently.
Path 1 · Keep Original Medicare
A Medicare Supplement can help with certain costs left by Original Medicare, while a separate Part D plan provides prescription coverage.
Path 2 · Choose a private plan
A private Medicare plan provides your Part A and Part B benefits. Many plans include Part D and may offer additional benefits.

It depends. People already receiving Social Security benefits at least four months before turning 65 are generally enrolled automatically in Parts A and B. Others usually need to apply through Social Security. Review your situation before assuming enrollment is automatic.
You may be able to delay Part B without a penalty if you have qualifying group health coverage based on your or your spouse’s current employment. Employer size and plan rules matter, so confirm how your employer coverage coordinates with Medicare before deciding.
COBRA does not extend the Part B Special Enrollment Period tied to current employment. That 8-month period generally begins when employment or active-employment group coverage ends, even if you elect COBRA.
Your federal Medigap Open Enrollment Period lasts six months and starts the first month you are 65 or older and enrolled in Part B. After that period, availability and pricing may depend on medical underwriting unless another right applies.
It is still important to evaluate Part D or other creditable drug coverage. Going 63 days or more without qualifying drug coverage may result in a late enrollment penalty if you enroll later.
