What Happens When You Turn 65: Navigating Medicare in 2025
If you’re about to turn 65, you’ve probably heard a lot about Medicare. But what exactly happens when that birthday rolls around? Is it automatic? Do you have to enroll? What does it cost, especially if you’re still working? This in-depth 2025 guide will walk you through everything you need to know about Medicare at age 65, from eligibility and enrollment to how Medicare works if you’re still employed. Whether you’re preparing for retirement or still actively working, understanding turn 65 Medicare options can help you make the best healthcare decisions for your future.
What Happens When You Turn 65?
Turning 65 is a major milestone — not just for life but for your healthcare. In the United States, turning 65 typically means you’re eligible for Medicare, a federally funded health insurance program for seniors and certain younger people with disabilities.
Why 65 is the Medicare Milestone
Age 65 has long been associated with Medicare eligibility. Although some individuals qualify earlier due to disability or specific conditions like End-Stage Renal Disease (ESRD) or ALS, most people become eligible at age 65. This age is significant because it’s the point where federal health benefits begin to kick in for most Americans.
Do I Automatically Get Medicare When I Turn 65?
In 2025, whether or not you automatically get Medicare when you turn 65 depends on your situation:
If You’re Receiving Social Security
If you’re already receiving Social Security or Railroad Retirement Board benefits at least four months before your 65th birthday, you’ll automatically be enrolled in:
-
Medicare Part A (Hospital Insurance) – usually premium-free
-
Medicare Part B (Medical Insurance) – with a monthly premium
You’ll receive your Medicare card in the mail about three months before your 65th birthday.
If You’re Not Receiving Social Security
If you’re not getting Social Security benefits yet (for example, you’ve chosen to delay retirement benefits), you must actively enroll in Medicare.
To avoid late penalties, it’s best to apply during your Initial Enrollment Period (IEP) — the 7-month window that starts three months before the month you turn 65, includes your birthday month, and extends three months after.
How Much Does Medicare Cost When You Turn 65 in 2025?
Cost is a key concern for anyone nearing Medicare age. In 2025, here’s what you can expect to pay when you turn 65 and enroll in Medicare:

Why Are You Forced to Get Medicare at 65?
You’re not truly forced to get Medicare at 65, but there are reasons why most people do — and why there are consequences for delaying.
Mandatory Enrollment for Certain Groups
If you’re receiving Social Security benefits, you’ll be automatically enrolled in Medicare Parts A and B when you turn 65. If you want to delay Part B, you must actively opt out to avoid being charged the premium.
Penalties for Late Enrollment
If you delay enrollment in Part B or Part D and don’t have other creditable coverage, you may face lifetime penalties:
-
Part B penalty: 10% for every 12-month period you were eligible but didn’t enroll
-
Part D penalty: 1% of the national base premium multiplied by the number of months without coverage
The Employer Coverage Exception
If you’re still working at 65 and have creditable employer coverage, you may delay Medicare enrollment without penalty. Just be sure the coverage is through an employer with 20 or more employees.
Is It a Good Idea to Get Medicare If You’re Still Working at 65?
Many Americans are choosing to work past 65, so this is a common question.
If You Have Employer Coverage
If your employer has 20+ employees and offers group health insurance, you can typically delay enrolling in Medicare Part B and/or Part D until you retire or lose that coverage.
-
Part A: Enroll if you qualify for premium-free coverage
-
Part B: Consider delaying to avoid paying for duplicate coverage
-
Part D: Only delay if your employer coverage includes creditable prescription drug coverage
Pros of Enrolling in Medicare at 65 While Working
-
Medicare may offer lower out-of-pocket costs
-
Gives you secondary coverage if your employer plan is primary
-
Helps cover deductibles or coinsurance
Cons

You’ll pay Part B premiums even if your employer coverage is comprehensive
