Medicare and Disability at Age 65
Already on Medicare—Do I Need to Sign Up Again at 65?
Turning 65 usually does not restart Medicare when you already qualify through disability, but it can create important new coverage opportunities.
If your Medicare Parts A and B are already active, you generally do not reapply for them simply because you are turning 65.
What Happens to Your Medicare at 65?
Your Medicare coverage does not ordinarily stop when you reach age 65. If you already have Medicare Part A and Part B because of a disability, that coverage generally continues. You normally keep your Medicare number and continue using your Medicare card.
Turning 65 is still an important Medicare milestone. It may provide a new opportunity to compare a Medicare Advantage plan, a Medicare Part D plan, or a Medicare Supplement.
Why Some People Receive Medicare Before 65
Medicare is not limited to people who are 65 or older. Many people become eligible earlier after receiving qualifying Social Security Disability Insurance benefits. Medicare generally begins automatically after 24 months of qualifying disability benefits, although different timing applies to certain conditions.
Medicare Part A
If Part A is already active, you generally do not submit a new Part A application just because you turn 65.
Medicare Part B
If Part B is already active, it normally continues at 65. Continue paying any applicable Part B premium.
A New Milestone
Your age-based Medicare eligibility can create new plan enrollment and Medigap opportunities worth reviewing.
Your Medigap Opportunity May Change at 65
This is one of the most important reasons not to ignore your 65th birthday. Federal law does not require every insurance company to offer every Medigap policy to someone under 65. Available plans and prices can therefore be limited for people receiving Medicare because of disability.
A New Six-Month Medigap Open Enrollment Period
Your federal Medigap Open Enrollment Period begins the first month you are both 65 or older and enrolled in Medicare Part B. It lasts six months. During this period, an insurer generally cannot deny a Medigap application or charge more because of your health history.
This may give you access to more Medicare Supplement choices or better pricing than you had while under 65. Learn how these policies work in our Medicare Supplement guide.
You May Also Review Your Advantage or Drug Plan
If you are already eligible for Medicare because of disability and then turn 65, Medicare provides a seven-month period in which you may join, switch or drop a Medicare Advantage or Medicare drug plan. That period generally includes the three months before your birthday month, your birthday month and the three months afterward.
Original Medicare Route
- Original Medicare Parts A and B
- An optional Medicare Supplement
- A separate Part D prescription plan
- Broad access to providers accepting Medicare
Medicare Advantage Route
- Part A and Part B benefits through a private plan
- Usually includes prescription coverage
- May include additional benefits
- Can use networks and prior authorization
Neither approach is automatically best for everyone. Compare your doctors, hospitals, prescriptions, travel habits, budget and expected healthcare needs before changing coverage.
When Should You Start Reviewing Your Options?
Begin about three months before the month you turn 65. Starting early gives you time to verify your current Medicare status, compare your choices and coordinate effective dates without feeling rushed.
Gather Information
Confirm Parts A and B, list your doctors and prescriptions, and review your current plan.
Verify Your Choices
Confirm plan approval, effective dates, premiums, provider participation and prescription coverage.
Do Not Miss Deadlines
Your age-65 Medicare Advantage and drug-plan enrollment opportunity continues, but Medigap follows its own six-month window.
Example: An October Birthday
If you turn 65 in October, begin your review around July. Your seven-month Medicare Advantage and drug-plan period generally runs from July through January. Your six-month Medigap Open Enrollment Period generally begins in October if your Part B is already active.
