Can You Get Medicare Before 65?

Yes. Age is the most common gateway to Medicare, but it's not the only one. Two additional pathways exist for people under 65.

Social Security Disability Insurance (SSDI)

If you have been receiving Social Security Disability Insurance benefits for 24 consecutive months, you automatically become eligible for Medicare — regardless of your age. The 24-month waiting period begins the month your SSDI payments start, not the month your disability began. Once that window closes, Medicare coverage begins automatically on the first day of the 25th month.

This is one of the most important — and most misunderstood — Medicare rules. Many people receiving disability benefits don't realize Medicare is coming, or assume they have to apply separately. In most cases, enrollment is automatic once you've met the 24-month threshold.

ALS (Amyotrophic Lateral Sclerosis)

If you are diagnosed with ALS, also known as Lou Gehrig's disease, Medicare eligibility begins the same month your Social Security disability benefits begin — there is no 24-month waiting period. This is a unique exception made specifically for ALS patients given the rapidly progressive nature of the disease.

End-Stage Renal Disease (ESRD)

If you have been diagnosed with permanent kidney failure requiring regular dialysis or a kidney transplant, you may be eligible for Medicare at any age. Generally, Medicare coverage begins the fourth month of dialysis treatment, though earlier coverage is possible if you participate in a home dialysis training program. Coverage following a kidney transplant begins the month of your hospital admission for the transplant.

Do You Qualify for Premium-Free Part A?

Not everyone pays the same amount for Medicare. Part A — which covers hospital stays, skilled nursing facility care, hospice, and some home health services — is free for most people, but only if you meet the work history requirement.

You qualify for premium-free Part A if you or your spouse worked and paid Medicare taxes for at least 40 quarters (10 years). This work does not need to be consecutive.

If you don't meet the 40-quarter threshold, you can still enroll in Part A, but you'll pay a monthly premium. In 2026, that premium is up to $505/month for those with fewer than 30 quarters of work history, and $278/month for those with 30 to 39 quarters. For most Americans who have worked a standard career, premium-free Part A is a given — but it's worth confirming if your work history is non-traditional, you've spent time working abroad, or you've had extended gaps in employment.

Are You Still Working at 65? This Changes Everything.

One of the most consequential Medicare eligibility questions we hear is: "I'm turning 65 but I'm still on my employer's health plan — do I have to sign up for Medicare now?"

The answer depends on the size of your employer, and getting it wrong can be expensive.

Employer with 20 or More Employees

If you work for a company with 20 or more employees and are covered under their group health plan, your employer coverage is considered "primary" — meaning it pays first. In this situation, you can delay enrolling in Medicare Part B without penalty. You'll have a Special Enrollment Period to sign up later when your employment ends or your employer coverage ends, whichever comes first.

Many people in this situation choose to enroll in premium-free Part A at 65 (since it costs nothing and provides a secondary layer of hospital coverage) while deferring Part B to avoid the monthly premium until they actually need it.

Employer with Fewer Than 20 Employees

If your employer has fewer than 20 employees, Medicare becomes the primary payer at 65, even if you're still working. In this case, delaying Part B is a serious mistake — your employer plan may pay very little or nothing if Medicare should have been primary. You need to enroll in Medicare on time.

COBRA and Retiree Coverage

Coverage through COBRA or a retiree health plan does not count as employer coverage for Medicare purposes. If your only health coverage at 65 is COBRA or a retiree plan, you should enroll in Medicare during your Initial Enrollment Period to avoid late penalties.

Marketplace / ACA Plans

If you are currently insured through a Marketplace plan (purchased through Covered California, for example), that coverage ends when you become eligible for Medicare. At that point, you'll also stop receiving any premium tax credits. Marketplace coverage is not a valid reason to delay Medicare enrollment.

Your Initial Enrollment Period (IEP)

When you first become eligible for Medicare at 65, you have a 7-month window to enroll. This is called your Initial Enrollment Period, and it runs as follows:

• 3 months before the month you turn 65
• The month of your 65th birthday
• 3 months after the month you turn 65

The timing of when you enroll within this window affects when your coverage begins. Enrolling during the 3 months before your birthday month means your coverage starts on the first day of your birthday month. Enrolling during your birthday month or in the 3 months after means your coverage is delayed by one to three months.

The takeaway: if you intend to enroll, doing so before your birthday month gives you the earliest possible start date and the smoothest transition.

What Happens If You Miss Your Enrollment Window?

Missing your Initial Enrollment Period without a valid reason — such as active employer coverage — triggers late enrollment penalties that follow you for the rest of your life.

Part B Late Penalty: For every 12-month period you were eligible for Part B but didn't enroll, your monthly Part B premium increases by 10%. Permanently. If you delayed three years without a qualifying reason, your premium is 30% higher than it would have been — every month, for the rest of your life.

Part D Late Penalty: For prescription drug coverage, the penalty is 1% of the national base beneficiary premium multiplied by the number of months you went without coverage. Like the Part B penalty, this is added to your monthly premium permanently.

These penalties exist to discourage people from waiting until they're sick to enroll. The system is designed to work when healthy people participate. Avoiding them is one of the clearest reasons to get good guidance before your 65th birthday.

Special Enrollment Periods: When Life Changes Your Timeline

Outside of your Initial Enrollment Period, Medicare offers Special Enrollment Periods (SEPs) triggered by specific qualifying events. The most common include:

Losing employer coverage: When you stop working or your employer health plan ends, you have 8 months to enroll in Part B without penalty. Note that the SEP begins when employment ends, not when COBRA begins — so don't assume COBRA resets your clock.

Moving to a new service area: If you relocate to a zip code where your current Medicare Advantage or Part D plan doesn't operate, you qualify for an SEP to switch plans.

Your plan leaves the market: If your Medicare Advantage or Part D plan is discontinued or loses its contract with Medicare, you have a guaranteed SEP to choose a new plan.

Qualifying for Extra Help / Low Income Subsidy: If you become eligible for a low-income subsidy program, you gain an SEP to enroll in or change a Part D plan.

Navigating SEPs correctly is nuanced. If you miss the SEP window, you may have to wait until the Annual Enrollment Period (October 15 – December 7) to make changes, which can leave you without coverage for months.

California-Specific Considerations

If you live in California, a few additional rules work in your favor.

California is one of a small number of states that provides additional Medigap protections beyond federal law. Under California's "Birthday Rule," you have a 60-day window each year — starting on your birthday — to switch to any Medigap plan with equal or lesser benefits than your current plan, without medical underwriting. This means insurers cannot deny you or charge you more based on your health history during that window.

This is a significant consumer protection that residents of most other states don't have. It gives California Medicare beneficiaries more flexibility to shop and switch their Medigap coverage over time — something worth understanding when you're making your initial plan selection.

Medicare Eligibility Checklist

Use this as a quick reference to assess your situation:

You are likely eligible for Medicare now if:

• You are 65 or older and a U.S. citizen or qualifying resident
• You have received SSDI benefits for 24 or more consecutive months
• You have been diagnosed with ALS
• You have End-Stage Renal Disease requiring dialysis or transplant

You should enroll now if:

• You are turning 65 and not covered by active employer insurance
• You are 65 and your employer has fewer than 20 employees
• Your only health coverage is COBRA, a retiree plan, or a Marketplace plan
• You are within your Initial Enrollment Period or a Special Enrollment Period

You may be able to delay enrollment if:

• You are actively employed and covered by an employer plan at a company with 20+ employees
• Your spouse is actively employed and you are covered under their employer plan at a company with 20+ employees

When in doubt, talk to a licensed broker before making a decision. The cost of getting this wrong — in penalties, coverage gaps, or unnecessary premiums — is real and lasting.

Frequently Asked Questions

Q: I turn 65 next month. Is it too late to enroll on time? Not necessarily. Your Initial Enrollment Period extends for 3 months after your birthday month, so you still have a window. However, enrolling after your birthday month means your coverage won't start on the first day of that month — there will be a delay. Contact us now and we'll walk through the timing with you.

Q: My spouse is on Medicare but I'm only 62. Can I enroll? No. A spouse's Medicare eligibility does not transfer to you. You must meet your own eligibility requirements based on your age, work history, or qualifying medical condition.

Q: I worked part-time for many years and I'm not sure if I have 40 quarters. How do I check? You can verify your work credits by creating an account at ssa.gov and reviewing your Social Security Statement, which shows your earnings history and estimated benefits. You can also call the Social Security Administration directly at 1-800-772-1213.

Q: I'm 67 and just retiring. Did I miss my Medicare enrollment window? If you had valid employer coverage through your own or a spouse's active employment, you should have a Special Enrollment Period beginning when that coverage ends. You'll have 8 months to enroll in Part B from the date your employer coverage ends. Act promptly — this window does not extend indefinitely.

Q: What if I'm still on my parents' health insurance at 26 and turning 65 at some point — can those overlap? Dependent coverage under a parent's plan ends at 26, so there's no scenario where these overlap at Medicare age. By 65 you'll have had your own coverage for decades.

Let's Figure Out Where You Stand

Medicare eligibility rules interact with your work history, your employer's size, your health status, your spouse's situation, and your state of residence. There's no single answer that applies to everyone — which is exactly why a 20-minute conversation with a knowledgeable broker is worth more than hours of research on your own.
