You can sign up for Medicare when you turn 65, no matter your work history

Medicare starts the month you turn 65. You do not have to be retired, and you do not have to have worked a certain number of years. If you were born on any day in a month, you become may be able to access on the first day of that month. For example, if your birthday is March 15, you can sign up starting March 1.

The catch is timing. If you do not sign up during your Initial Enrollment Period — the seven-month window that includes the three months before you turn 65, the month you turn 65, and the three months after — you may pay a penalty for the rest of your life. The penalty is a percentage added to your monthly premium, and it does not go away.

There are a few exceptions where you can sign up late without penalty, but they are narrow. Most people need to act during that seven-month window.

Key Takeaways

  • Your Initial Enrollment Period is seven months long: three months before you turn 65, the month you turn 65, and three months after.
  • If you miss this window and do not have an exception, you will pay a permanent penalty on your Part B and Part D premiums.
  • You can sign up online at Medicare.gov, by phone at 1-800-MEDICARE, or in person at your local Social Security office.
  • If you are still working and have health insurance through your job, you may have a Special Enrollment Period that lets you sign up later without penalty.
  • Medicare Part A (hospital insurance) is usually free if you or your spouse paid Medicare taxes for at least 10 years.

What happens if you sign up late

Missing your Initial Enrollment Period triggers a late enrollment penalty that stays on your record. For Part B (doctor and outpatient care), the penalty is 10 percent of the standard premium for each full year you were may be able to access but not signed up. If you were may be able to access for two years and did not sign up, your penalty is 20 percent. This extra amount is added to your monthly bill forever — even after you finally sign up.

Part D (prescription drug coverage) works the same way. If you go 63 days or more without drug coverage and then sign up later, you pay a penalty of about 1 percent of the national average Part D premium for each month you were without coverage. Again, this penalty is permanent.

Part A (hospital insurance) does not usually have a late enrollment penalty if you have it through work or your spouse's work. But if you do not have coverage through work and miss your window, you pay 10 percent more for Part A.

When you can sign up late without a penalty

A Special Enrollment Period lets you sign up outside your Initial Enrollment Period without paying a penalty. The most common reason is that you are still working and have health insurance through your employer or your spouse's employer. If your employer has 20 or more employees, you can wait to sign up for Part B until you retire or lose that coverage, then you have eight months to sign up without penalty.

Other situations that open a Special Enrollment Period include losing your job, losing employer coverage, moving out of your plan's service area, or having your plan end. You also get a Special Enrollment Period if you are receiving benefits from the Railroad Retirement Board or if you are a federal employee who did not sign up during your Initial Enrollment Period.

The key is that you must sign up within the time frame tied to your specific event. For example, if you lose employer coverage, you have eight months from the date coverage ends. If you miss that important date, the penalty applies. You will need to show proof of your situation — a letter from your employer, a notice that your plan is ending, or documentation of your job loss.

How to sign up during your Initial Enrollment Period

You have three ways to sign up: online, by phone, or in person. The fastest is usually online at Medicare.gov. You will need your Social Security number, your date of birth, and information about any current health coverage you have. The site walks you through which parts of Medicare you need and shows you what your costs will be.

If you prefer to talk to someone, call 1-800-MEDICARE (1-800-633-4227). Representatives are available seven days a week, and they can answer questions about your specific situation. They can also sign you up over the phone.

You can also visit your local Social Security office in person. Bring your Social Security card, proof of citizenship or legal residency, and proof of age. If you have current health coverage, bring that information too. Social Security offices are usually less busy early in the week and early in the morning.

Whichever way you sign up, do it early in your Initial Enrollment Period. If you wait until the last month, processing delays could mean your coverage does not start on time.

What to do if you turned 65 before you knew about Medicare

If you missed your Initial Enrollment Period and did not know you were supposed to sign up, you still owe the late enrollment penalty. There is no exception for not knowing. However, you can sign up now and your coverage will start the first day of the month after you sign up.

Before you sign up, check whether you have a Special Enrollment Period. If you were working and had employer coverage, or if you lost coverage recently, you may not owe a penalty. Call 1-800-MEDICARE and describe your situation. A representative can tell you whether a Special Enrollment Period applies to you.

If you do owe a penalty, you will pay it as long as you have Medicare. It does not expire. The only way to avoid it going forward is to sign up now and keep your coverage active.

Medicare before age 65: who qualifies

Most people cannot get Medicare until 65, but there are exceptions. If you have been receiving Social Security Disability Insurance (SSDI) for 24 months, you become may be able to access for Medicare at any age. If you have End-Stage Renal Disease (ESRD) — permanent kidney failure requiring dialysis or transplant — you can get Medicare regardless of age. If you have ALS (amyotrophic lateral sclerosis), you can get Medicare when ready without waiting.

If you fall into one of these categories, you will receive a notice from Social Security or your dialysis center telling you when you are may be able to access. You still need to sign up during your Initial Enrollment Period to avoid penalties, even though your period may start at a different age than 65.

Questions to ask your doctor or Social Security

Before your Initial Enrollment Period ends, ask your doctor which Medicare plan makes sense for your medications and doctors. Ask whether your current doctors take Medicare and which plan they are in. Ask your pharmacist which plans cover your prescriptions at the lowest cost.

When you call Social Security or Medicare, ask whether you have a Special Enrollment Period based on your work or coverage history. Ask what the penalty will be if you sign up late. Ask when your coverage will start based on when you sign up. If you are still working, ask whether your employer coverage affects when you need to sign up for Part B.

Frequently Asked Questions

What if I turn 65 in the middle of the month?

Your Initial Enrollment Period starts three months before the month you turn 65, regardless of which day in that month your birthday falls. If you turn 65 on March 15, your enrollment period runs from December 1 through June 30. Your coverage can start as early as the first day of the month you turn 65.

Do I have to sign up for all parts of Medicare at once?

No. You can sign up for Part A and Part B separately from Part D (drug coverage). However, if you wait to sign up for Part D later, you may owe a penalty unless you have a Special Enrollment Period. Part A and Part B do not have the same penalty structure, so timing matters differently for each.

What if I am still working at 65 and have health insurance through my job?

You should still sign up for Part A (hospital insurance) because it is usually free and does not affect your employer coverage. For Part B, you may be able to wait until you retire or lose coverage without paying a penalty, but you must have a Special Enrollment Period. Contact your employer's benefits office to confirm your coverage qualifies.

Can I change my mind after I sign up?

Yes, but only during specific times. You have a seven-day window after you sign up to cancel. After that, you can make changes during the Annual Enrollment Period (October 15 through December 7 each year) or if you have a may have access to life event like moving or losing coverage.

What if I do not know my exact birth date?

Contact Social Security before you try to sign up for Medicare. They can verify your birth date in their records. You will need this information to sign up, and it needs to match what Social Security has on file.
