Age 65 Still working — enrollment timing depends on employer coverage

Medicare eligibility age has not changed to 67. Social Security full retirement age and Medicare eligibility age are not the same.

What age do you qualify for Medicare?

Most people qualify for Medicare at age 65. This has not changed. Even though Social Security full retirement age has increased to 67 for people born in 1960 or later, the Medicare eligibility age remains 65.

Medicare and Social Security are separate programs. You do not need to be receiving Social Security benefits to enroll in Medicare, and delaying Social Security does not delay your Medicare eligibility.

If you are turning 65 soon, your Initial Enrollment Period opens three months before your birthday month. Acting during this window helps you avoid late enrollment penalties for Part B and Part D and ensures your coverage starts without a gap.

Common Confusion

Social Security full retirement age is now 67 for many people. But that change does not affect Medicare. Medicare eligibility still generally begins at age 65 — regardless of when you claim Social Security.

Medicare Eligibility Age Chart

Use this chart to find the row that best matches your situation. Medicare eligibility timing and enrollment rules can differ significantly depending on your circumstances.

Situation Type When eligibility may begin What it means for you
Turning 65 Standard Age 65, generally the first day of your birthday month Most people first qualify for Medicare at 65. You have a 7-month Initial Enrollment Period around your birthday month.
Birthday on the 1st of the month Standard The month before you turn 65 Medicare rules treat birthdays on the 1st as occurring the prior month. Your coverage and IEP may start a month earlier.
Under 65 with a disability (SSDI) Early Generally after 24 months of receiving SSDI benefits If you have been receiving Social Security Disability Insurance for 24 consecutive months, Medicare eligibility may begin automatically. The wait period begins from your first month of SSDI entitlement.
ALS (amyotrophic lateral sclerosis) Early May begin sooner — the 24-month wait is waived People diagnosed with ALS who qualify for SSDI are not subject to the standard 24-month waiting period. Medicare eligibility may begin with SSDI entitlement.
End-Stage Renal Disease (ESRD) Special May qualify at any age with sufficient work history ESRD can qualify someone for Medicare before age 65. There are work history requirements and a waiting period that applies in some cases. Contact Social Security directly for your specific situation.
Still working at 65 with employer coverage Working Eligible at 65, but enrollment timing depends on employer size and coverage type You are eligible at 65, but may be able to delay some parts of Medicare if you have qualifying active employer coverage. Rules differ based on whether your employer has 20+ employees. Delaying incorrectly can result in penalties.
Not enough work credits (fewer than 40 quarters) Standard Age 65, but Part A may require a premium If you — and your spouse — have not worked and paid Medicare taxes for at least 40 quarters combined, you may still enroll in Medicare at 65, but you would pay a monthly premium for Part A. Part B premiums apply regardless.
Spouse's work record (never worked yourself) Standard Age 65, based on spouse's work history You may qualify for premium-free Part A based on a current or former spouse's work record, provided they worked at least 40 quarters. You must be at least 65 and the marriage generally must have lasted at least 10 years if divorced.

Important Note

This chart is a general educational reference. Medicare eligibility rules have exceptions and can depend on your specific work history, benefit dates, and coverage situation. Contact Social Security or a licensed Medicare agent to confirm your personal eligibility timing.

Can you get Medicare before age 65?

Yes — in certain situations. Some people qualify for Medicare before age 65 through a qualifying disability, ALS, or End-Stage Renal Disease. Simply being eligible for early Social Security retirement at age 62 does not make you eligible for Medicare early.

1
Social Security Disability Insurance (SSDI) After receiving SSDI benefits for 24 consecutive months, Medicare eligibility generally begins automatically. The 24-month clock starts from the first month you are entitled to SSDI — not the month you applied.
2
ALS (Lou Gehrig's Disease) If you are diagnosed with ALS and qualify for SSDI, the standard 24-month waiting period is waived. Medicare eligibility may begin with your first month of SSDI entitlement.
3
End-Stage Renal Disease (ESRD) ESRD can qualify someone for Medicare at any age, provided there is sufficient work history (your own or a spouse's). A waiting period may apply depending on when dialysis began or if you have had a kidney transplant.

What About Age 62?

You cannot get Medicare simply because you are 62 or because you claimed early Social Security retirement. Medicare eligibility is separate and generally does not begin until 65 — unless a qualifying disability, ALS, or ESRD applies.

Early Medicare eligibility — what to know

  • The 24-month SSDI wait starts from your date of SSDI entitlement, not your application date or approval date.
  • ALS patients enrolled in SSDI are automatically enrolled in Medicare — no waiting period applies.
  • ESRD eligibility requires your own or a spouse's sufficient work record. Contact Social Security to review your specific situation.
  • If you qualify through disability and later turn 65, your Medicare coverage continues — you don't need to re-enroll.
  • People under 65 on Medicare are generally eligible for the same Medicare Advantage and Supplement plans, though availability varies by state.

Is the Medicare eligibility age changing to 67?

No. As of 2026, the Medicare eligibility age is still generally 65. There has been no law passed that changes the Medicare eligibility age to 67.

The confusion often comes from Social Security. Social Security's full retirement age has gradually increased to 67 for people born in 1960 or later. But Medicare and Social Security are separate federal programs with separate eligibility rules. A change to Social Security's full retirement age does not change Medicare's eligibility age.

You may have also seen proposals in Congress to raise the Medicare age. As of this writing, no such change has been enacted. Until a law is passed and takes effect, Medicare eligibility generally begins at age 65.

Bottom Line

Medicare eligibility age: 65. Social Security full retirement age: up to 67 (depending on birth year). These are different programs with different rules. You do not need to wait until 67 to enroll in Medicare.

When should you apply for Medicare?

Your Initial Enrollment Period (IEP) is a 7-month window centered around your 65th birthday month. Enrolling during the first three months of your IEP — before your birthday month — generally means your coverage starts on the first day of your birthday month, with no gap.

Waiting until your birthday month or the months after can delay the start of your coverage. And waiting until after the IEP ends entirely may trigger late enrollment penalties for Part B and Part D that last as long as you have Medicare.

Enrolling in months 1–3 (before your birthday month) generally means coverage begins on the first day of your birthday month. Enrolling in months 5–7 may delay the start of your coverage.

Timing mistakes can be costly.Schedule a review before your IEP opens or closes.

Other Medicare enrollment periods

IEP
Initial Enrollment Period 7 months around your 65th birthday. Your main window — use it.
SEP
Special Enrollment Period Available when you lose qualifying employer coverage. Generally 8 months for Part B, 63 days for Part D.
GEP
General Enrollment Period January 1 – March 31 each year. Coverage starts July 1. Late enrollment penalties may apply.
AEP
Annual Enrollment Period Oct 15 – Dec 7 each year. Change Medicare Advantage or Part D plans for the next calendar year.

Do you automatically get Medicare at 65?

Some people are automatically enrolled in Medicare Part A and Part B when they turn 65. Others need to actively sign up. Whether you are automatically enrolled depends on whether you are already receiving Social Security or Railroad Retirement benefits before your 65th birthday.

Likely auto-enrolled If you are already receiving Social Security or Railroad Retirement Board benefits at least 4 months before you turn 65, you will generally be automatically enrolled in Medicare Part A and Part B. Your Medicare card will arrive in the mail about 3 months before your 65th birthday.
!
Must sign up yourself If you are not yet receiving Social Security or Railroad Retirement benefits when you turn 65 — for example, because you are still working or delayed claiming — you need to actively sign up for Medicare through Social Security. If you miss your IEP, you may face penalties and coverage gaps.

Part B Opt-Out

Even if you are auto-enrolled in Part B, you can decline it — for example, if you have qualifying employer coverage. But be careful: if you decline Part B and later want it back, you may owe a late enrollment penalty. Talk to a licensed agent before opting out.

Not sure if you'll be auto-enrolled?

The answer depends on your Social Security benefit start date, your employer coverage, and other factors. We can help you figure out what steps you need to take — and when — so you don't miss your window or face unnecessary penalties.

What if you're still working at 65?

If you are still working at 65 and covered by an employer health plan, you may be able to delay some parts of Medicare without a penalty — but the rules are more complex than many people realize. Getting this wrong can result in a permanent Part B penalty, a gap in coverage, or unexpected costs.

The key question is the size of your employer. The rules are different depending on whether you work for a company with 20 or more employees versus fewer than 20.

20+
Employer with 20 or more employees Your employer coverage is generally the primary payer and Medicare is secondary. You may be able to delay Part B enrollment without a penalty. You will have a Special Enrollment Period when that employer coverage ends.
<20
Employer with fewer than 20 employees Medicare is generally the primary payer in this situation. You should likely enroll in Medicare at 65 even if you remain covered by your employer's plan. Failing to enroll when required can result in gaps and permanent penalties.

HSA Contributor? Read This

If you contribute to a Health Savings Account (HSA), enrolling in Medicare Part A stops your ability to make new HSA contributions. If you plan to keep contributing, you will need to delay both Part A and Part B — and stop Social Security benefits if you have started them. This is a complex area with significant financial implications. Get advice before you decide.

Questions to answer first

  • Does my employer have 20 or more employees?
  • Is my employer coverage "active" employer coverage — not COBRA or retiree coverage?
  • Am I contributing to an HSA, and do I want to keep doing so?
  • Is my drug coverage through my employer creditable for Part D purposes?
  • When my employer coverage ends, do I know my Special Enrollment Period window?

Don't guess on this one.The wrong decision can be permanent.

Medicare eligibility questions, answered

Most people become eligible for Medicare at age 65. Some people qualify earlier — before age 65 — due to a qualifying disability after 24 months of Social Security Disability Insurance (SSDI) benefits, an ALS diagnosis, or End-Stage Renal Disease (ESRD).
Generally, no. Medicare does not begin at age 62. Standard Medicare eligibility begins at age 65. However, some people under 65 may qualify earlier through disability, ALS, or End-Stage Renal Disease. Simply being eligible for early Social Security retirement does not make you eligible for Medicare before 65.
No. As of 2026, the Medicare eligibility age is still generally 65. Social Security full retirement age has increased to 67 for people born in 1960 or later, but that change does not affect Medicare. Medicare and Social Security are separate programs with separate eligibility ages.
Yes, in certain situations. You may qualify for Medicare before age 65 if you have received Social Security Disability Insurance benefits for at least 24 months, you have been diagnosed with ALS (amyotrophic lateral sclerosis), or you have End-Stage Renal Disease and meet the work history requirements.
Some people are automatically enrolled in Medicare Part A and Part B at 65 — specifically those already receiving Social Security or Railroad Retirement benefits at least four months before their 65th birthday. Others need to actively sign up through Social Security. If you are not sure whether you will be auto-enrolled, contact Social Security or speak with a licensed Medicare agent before your birthday month arrives.
Your Initial Enrollment Period is a 7-month window: the 3 months before your 65th birthday month, your birthday month, and the 3 months after. Enrolling during the first 3 months of your IEP means your coverage generally starts on the first day of your birthday month. Waiting until your birthday month or later can delay your coverage start date by one or more months. Missing your IEP entirely may result in permanent late enrollment penalties.
You may be able to delay Medicare if you have qualifying active employer coverage. The rules depend on the size of your employer. If your employer has 20 or more employees, your employer coverage is generally primary and you may delay Medicare without penalty. If your employer has fewer than 20 employees, Medicare is generally primary and you should likely enroll at 65. You also cannot contribute to an HSA once you enroll in Medicare Part A. Talk with a licensed Medicare agent before making this decision.
A small number of people may not qualify for Medicare at 65 or may not qualify for premium-free Part A. This can happen if you — and your spouse — have not worked and paid Medicare taxes for at least 40 quarters (10 years). In those cases, you may still be able to buy into Medicare, but you would pay a premium for Part A. There may also be additional requirements for non-citizens and certain residents.
You may still be able to get Medicare at 65 even if you never worked, through a spouse's work record. If your spouse has worked and paid Medicare taxes for at least 40 quarters, you may qualify for premium-free Part A based on their record. If you cannot qualify through a spouse's record, you may still enroll in Medicare but would pay a premium for Part A. Contact Social Security to review your specific situation.
Medicare Part A (hospital insurance) is premium-free for most people at age 65 if they or their spouse worked and paid Medicare taxes for at least 40 quarters. Medicare Part B has a monthly premium — $185.00 per month in 2026 for most people, though higher earners pay more through IRMAA. Additional premiums apply for Medicare Advantage or Part D drug coverage.
Medicare eligibility means you qualify for Medicare based on age, disability, or a qualifying condition. Medicare enrollment means you have actually signed up and your coverage is active. Being eligible does not mean you are automatically enrolled, and missing your enrollment window can result in late enrollment penalties for Part B and Part D that last as long as you have Medicare.
