Medicare Without Social Security: How to Sign Up

Older woman calling about Medicare enrollment

Yes, you can get Medicare without collecting Social Security. Claiming retirement benefits is not a requirement for Medicare. The difference is that people who aren’t receiving benefits are not signed up automatically, so you have to apply yourself through the Social Security Administration (SSA). CMS says so directly: anyone not receiving a Social Security or Railroad Retirement Board (RRB) benefit must file an application for Medicare. This guide walks through who qualifies, how to apply, what it costs, and the deadlines that protect you from penalties.

TL;DR

Medicare and Social Security benefits are separate. You can enroll in Medicare at 65 without claiming retirement benefits.
If you aren’t getting Social Security or RRB benefits, you won’t be enrolled automatically. You apply with SSA, ideally in the three months before you turn 65.
Part A is premium-free only if you have enough work credits. Otherwise you may be able to buy it, and in 2026 the monthly premium is $311 or $565.
Missing your first enrollment window can mean a lifelong Part B penalty, unless you have qualifying coverage or another exception.
Once you’re enrolled, you still need to choose how to fill the gaps in Original Medicare. That is where a local agent can help.

Why Medicare doesn’t depend on claiming Social Security

Medicare and Social Security run side by side, and that causes most of the confusion. Medicare.gov explains that Medicare is health insurance for people 65 or older who meet citizenship or residency rules. Whether you get it automatically or have to actively sign up depends on whether you’ve started retirement or disability benefits from Social Security before you turn 65.

In practice, there are two paths:

Automatic enrollment. If you are already receiving Social Security or RRB benefits as you approach 65, Medicare Part A and Part B generally start without an application.
Active enrollment. If you are still working, you plan to delay retirement benefits until 66, 67 or 70, or you never qualified for benefits, you must sign up on your own.

Many people delay Social Security to earn a bigger monthly check. That choice has no effect on your right to Medicare. It only changes how you get signed up.

Who can get Medicare without Social Security benefits

Three situations come up most often.

You’re 65 and still working or delaying benefits

This is the most common case. You are eligible for Medicare at 65 because of your age and your work history, but you haven’t filed for retirement benefits. You apply for Medicare separately. If you or your spouse is still covered by an employer plan, the timing of Part B matters. Our guide to Medicare while working explains how employer coverage interacts with enrollment.

You never worked, or didn’t work long enough

Work and tax history don’t decide whether you can have Medicare. They decide what you pay for Part A. Healthline notes that work history affects whether you qualify for premium-free Part A, not whether you qualify for Medicare at all. CMS states that premium-free Part A based on age requires you to be 65 or older and eligible for monthly Social Security or RRB cash benefits. If you don’t meet that test, you may still be able to buy coverage, as covered below. A spouse’s work record can also count toward premium-free Part A in many cases, so it is worth asking SSA about yours.

You’re not a U.S. citizen

Citizenship is not the only route. According to Medicare.gov’s enrollment guide, you can buy Part B without premium-free Part A if you are 65 or older, live in the U.S., and are either a citizen or a lawful permanent resident who has lived here continuously for five years before applying for Part B. The Congressional Research Service adds that noncitizens must be lawfully present in the United States to receive premium-free Part A or Part B benefits. Immigration rules have changed recently, so confirm your status and the current rules with SSA before you apply.

What Medicare costs if you don’t get premium-free Part A

Most people pay nothing for Part A because they or a spouse paid Medicare taxes long enough. If that isn’t you, you may be able to buy it. Medicare.gov lists the 2026 Part A premium as either $311 or $565 per month, depending on how long you or your spouse worked and paid Medicare taxes.

Work history	Part A premium in 2026
40 or more quarters (about 10 years)	$0 for most people
30 to 39 quarters	$311 per month
Fewer than 30 quarters	$565 per month

Two more points matter if you’re buying Part A:

Medicare.gov states that you also have to sign up for Part B to buy Part A.
Part B is not free for anyone. The standard 2026 Part B premium is $202.90 per month, according to Medicare.gov.

Because you aren’t receiving Social Security, no benefit check exists to deduct the Part B premium from. Expect to be billed instead. Higher-income households can pay more than the standard Part B amount, which is explained in our article on Medicare IRMAA income lines.

If these premiums are a stretch, ask SSA or your state about Medicare Savings Programs. Medicare.gov notes that people enrolled in one of these programs generally don’t pay the Part B late penalty.

What Medicare costs if you don't get premium-free Part A

When to apply: your Initial Enrollment Period

Your first chance to sign up is called the Initial Enrollment Period. Medicare.gov describes it as starting three months before the month you turn 65 and ending three months after that month. That is a seven-month window, centered on your birthday month.

Seven-month Medicare enrollment timeline around age 65

For someone not receiving Social Security, the safest approach is simple: apply in the three months before you turn 65. The Medicare & You handbook tells people close to 65 who aren’t getting Social Security or RRB benefits to sign up at SSA.gov/medicare/sign-up, or to contact Social Security three months before turning 65 to set up an appointment.

Applying early gives you room to fix mistakes, find missing paperwork and pick a drug plan or supplement without a rush. For a full breakdown of every window, see our explainer on Medicare enrollment periods.

How to sign up for Medicare without Social Security

You have three ways to apply. AARP reports the same options that SSA lists: online, by phone, or in person at a local Social Security office. The phone number is 1-800-772-1213.

Online. Medicare.gov calls online the easiest and fastest way to sign up. You create a secure my Social Security account, then complete the application. About two weeks after you sign up, SSA mails a welcome package with your Medicare card.
By phone. Call 1-800-772-1213 and ask to apply for Medicare Part A and Part B. Ask for an appointment if the line is busy.
In person. Visit your local Social Security office. Check hours and whether you need an appointment before you go.

One detail trips people up. The CMS-40B form is for people who already have Part A but not Part B. Its instructions say that if you don’t have Part A, you should contact Social Security at 1-800-772-1213 to apply for Medicare for the first time. So a first-time applicant doesn’t start with that paper form.

What to have ready

SSA’s sign-up page says the basic information you’ll need includes your Social Security number and where you were born, including city, state and country. Healthline adds that if you don’t receive benefits, you may also be asked for your date of birth and citizenship status, and that an original birth certificate can serve as proof of age.

A short checklist:

Your Social Security number
Date and place of birth, with a birth certificate if SSA asks for proof of age
Proof of citizenship or lawful presence, if you’re asked
Details about any current employer coverage, including start and end dates
Your current address and phone number

Our Medicare enrollment checklist lays out the same steps with deadlines so you can tick them off.

If you don’t have a Social Security number

SSA’s sign-up information asks for your Social Security number, so it is part of the process. If you don’t have one, call SSA at 1-800-772-1213 or visit a local office before your enrollment window opens. They can tell you what’s needed in your situation. Don’t wait until the last month of your window to find out.

What happens if you wait: late enrollment penalties

Delaying isn’t always a problem. It becomes one when you have no other qualifying coverage. Medicare.gov explains the rules this way:

The Part B penalty is an extra 10% for each year you could have signed up but didn’t.
It isn’t a one-time fee. You pay it for as long as you have Part B.
If you have to buy Part A, its premium may go up 10%, and you pay the higher amount for twice the number of years you delayed.
Generally, you won’t pay a Part B penalty if you qualify for a Special Enrollment Period or are in a Medicare Savings Program.

Here is a worked example using the 2026 standard premium of $202.90. If you went two full years without Part B when you should have had it, the penalty would be 20% of the standard premium. That is roughly $40.58 added to your monthly bill, every month, for life. The exact amount is recalculated as premiums change, so treat this as an illustration, not a quote.

The people who are usually protected are those with coverage through current work, theirs or a spouse’s. COBRA and retiree plans don’t give that protection, which surprises many. We cover that trap in COBRA vs. Medicare. For a deeper look at costs and exceptions, read our guide to the Medicare late enrollment penalty. Veterans and military families should also see how TRICARE and Medicare fit together.

A simple plan for turning 65 without Social Security

Here is the sequence we walk clients through when they aren’t claiming benefits yet.

Six months before your birthday: Find out whether you have enough work credits for premium-free Part A, and whether a spouse’s record could help. Ask SSA if you aren’t sure.
Four months before: Decide whether you have employer coverage that lets you delay Part B. Ask your employer’s benefits office whether the plan is primary to Medicare.
Three months before: Apply through your my Social Security account, by phone or in person.
Within the first month or two: Look for your welcome package and Medicare card. Check that Part A and Part B start dates match what you expected.
Before coverage starts: Decide how you’ll cover what Original Medicare doesn’t. The main routes are a Medicare Advantage plan or a Medicare Supplement (Medigap) policy, plus a Part D prescription drug plan.

Step five is where most people feel lost. Original Medicare leaves out some costs, and the right fix depends on your doctors, your prescriptions and your budget. If you’re new to all this, our simple guide to getting started with Medicare is a good first read.

Disability, ALS and other routes to Medicare

Age 65 isn’t the only way in. Social Security’s overview of Medicare eligibility is tied to age and to disability or specific conditions. People who’ve received Social Security Disability benefits for 24 months, or who have end-stage renal disease, can qualify before 65. For people with ALS, our article on ALS and Medicare eligibility explains how enrollment works. These situations involve benefits, so you usually will be enrolled through Social Security in a different way than the 65 path above.

Getting help choosing coverage in Northern Illinois and Southern Wisconsin

Applying to SSA gets you Original Medicare. It doesn’t choose your supplemental coverage or your prescription plan for you. We’re Almond Insurance, a Medicare agency in Rockford, Illinois, and we help people in Northern Illinois and Southern Wisconsin through that part of the process. Our approach is built around plain language and patient, step-by-step education, with no jargon.

Plan comparison help across Medicare Advantage and Medicare Supplement options.
Prescription plan review so your Part D plan fits the medications you take.

Common mistakes to avoid

Assuming you’ll be signed up automatically. That only happens if you’re already receiving benefits. Otherwise, you have to apply.
Waiting until after your birthday month. Your window runs three months past it, but you want your coverage to start when you need it.
Treating COBRA or retiree coverage as the same as active employer coverage. It generally doesn’t protect you from the Part B penalty.
Skipping the Part B premium bill. With no Social Security check to deduct from, you are billed. Set up payment so you don’t risk losing coverage.
Forgetting the drug plan. Part D is separate from Part A and Part B, and it has its own enrollment rules and penalties.

FAQ

Can I apply for Medicare if I haven’t claimed Social Security?

Yes. Medicare doesn’t require you to be collecting retirement benefits. You apply through SSA online, by phone at 1-800-772-1213, or at a local office. Do it in the three months before you turn 65 to avoid gaps.

Is Medicare available to people who never worked?

Often yes. Work history decides what you pay for Part A, not whether you can enroll. If you don’t qualify for premium-free Part A, you may be able to buy it, which in 2026 costs $311 or $565 per month, and you must also sign up for Part B.

Can non-U.S. citizens get Medicare?

Sometimes. Noncitizens generally must be lawfully present in the U.S. A lawful permanent resident who has lived here continuously for five years may be able to buy Part B at 65. Rules have changed recently, so check your status with SSA.

What is the penalty for not enrolling in Medicare at 65?

The Part B penalty is an extra 10% for each year you could have signed up but didn’t, and you pay it as long as you have Part B. You generally avoid it if you had a Special Enrollment Period, such as through current employer coverage, or you’re in a Medicare Savings Program.
