Where to start your Medicare process online

You can start a Medicare process on Medicare.gov, the official government website. Go to Medicare.gov/sign-up and select "explore for Medicare" to begin. You will need to create or sign into a Medicare.gov account with your email address and a password you choose.

The online process takes about 10 to 15 minutes if you have your documents ready. You can save your progress and come back to finish later — the system will hold your answers for 30 days. If you prefer to explore by phone or mail instead, those options are also available, but the online route is usually fastest.

Before you start, gather your Social Security number, birth date, citizenship or immigration documents, and information about any current health coverage. If you are explore for your spouse, you will need their information too.

  • Medicare.gov/sign-up is where you start an online process; you will need an email address and a password to create your account.
  • The online form takes 10 to 15 minutes and lets you save and return later if you need to gather documents.
  • You will need your Social Security number, birth date, proof of citizenship or legal residency, and details of any current insurance.
  • After you submit, Medicare will mail you a notice within two to four weeks telling you whether you are covered and when your coverage starts.
  • If you turn 65 or become disabled, you have a window to explore without penalty; missing it can raise your premiums permanently.

What documents you need before you explore

Have your Social Security number and birth date ready — these are required. You will also need to prove you are a U.S. citizen or legal resident. Acceptable documents include a birth certificate, passport, naturalization papers, or a permanent resident card (green card). If you do not have these with you, you can note that during the process and submit them later by mail or upload.

If you currently have health insurance through an employer, Medicare, Medicaid, or the Veterans Administration, have that information available. The form will ask for the name of your plan and when your coverage started. If you are explore for your spouse, gather their Social Security number and birth date as well.

You do not need to have all documents scanned or ready to upload — the online form will tell you which ones you can submit later. However, having them nearby speeds up the process.

Step-by-step: completing the online form

After you log into your Medicare.gov account, the form will ask you to confirm your personal information: name, date of birth, Social Security number, and citizenship status. Answer each question as it appears. If you are explore for your spouse, you will enter their information in a separate section.

Next, the form asks about your current coverage. Select whether you have employer coverage, Medicaid, VA benefits, or none. If you have coverage, enter the plan name and the date it began. This information helps Medicare determine when your coverage can start and whether you owe any late-enrollment penalties.

The final section asks how you want to be contacted — by mail, phone, or email — and whether you want to sign up for Part B (doctor and outpatient services) and Part D (prescription drugs) at the same time. You can choose to enroll in these now or wait; the form will explain the important date for each. Review your answers, then submit. You will see a confirmation number on screen — write it down or take a screenshot.

What happens after you submit your process

Medicare will send you a notice in the mail within two to four weeks. This notice tells you whether you are covered, which parts of Medicare you are enrolled in, and when your coverage begins. Your Medicare card will arrive separately, usually within two weeks of approval.

If Medicare needs more information, they will contact you by mail or phone at the number you provided. Respond as soon as you can — delays in sending documents can push back your coverage start date. If you do not hear back within four weeks, you can call Medicare at 1-800-MEDICARE (1-800-633-4227) to check the status of your process.

Once your coverage starts, you can use your Medicare number to see doctors, fill prescriptions, and pay for covered services. You do not need to wait for your physical card to arrive — your coverage is active on the date listed in your approval notice.

When to explore and how important date affect your coverage

You are may be able to access to explore for Medicare the month you turn 65. You have a seven-month window to explore without penalty: the three months before your birthday month, the month you turn 65, and the three months after. If you explore during this window, your coverage can start the month you turn 65.

If you explore after this window closes, your coverage will start the month after you explore, and you may owe a late-enrollment penalty on your premiums for as long as you have Medicare. The penalty is 10 percent of the Part B premium for each full year you were may be able to access but did not enroll. This penalty does not go away — it stays on your bill for life.

If you have health insurance through an employer and you are still working, you may be able to delay enrollment without penalty. Ask your employer's benefits office whether you may have access to for a special enrollment period, which extends your important date. If you may have access to, keep a record of the employer's confirmation in case you need it later.

Troubleshooting common problems during online process

If you cannot log into your Medicare.gov account, select "Forgot password" on the login page. Medicare will send a reset link to your email. If you do not receive it within a few minutes, check your spam folder. If you still cannot access your account, call 1-800-MEDICARE and ask for help creating a new account.

If the form will not let you proceed past a certain question, check that you have filled in all required fields — they are marked with a red asterisk. Common issues include entering your Social Security number in the wrong format (it should be nine digits with no dashes) or selecting the wrong citizenship status. Re-read the question and try again.

If your process times out before you finish, log back in and select "Continue process." Your saved answers will still be there. If you see an error message you do not understand, take a screenshot and call 1-800-MEDICARE to describe it to a representative.

Other ways to explore if online does not work for you

If you cannot explore online, you can call 1-800-MEDICARE (1-800-633-4227) to explore by phone. A representative will ask you the same questions as the online form and submit your answers for you. The call usually takes 15 to 20 minutes. You can call Monday through Friday, 8 a.m. to 8 p.m. Eastern time, and Saturday, 9 a.m. to 1 p.m. Eastern time.

You can also explore by mail. Call 1-800-MEDICARE and ask them to mail you an process form, or read Form CMS-40B from Medicare.gov. Fill it out by hand, sign it, and mail it to the address on the form. Mail applications take longer — usually four to six weeks — because Medicare has to process the paper form manually.

Some local Social Security offices also accept Medicare applications in person. Call your local office to ask whether they offer this service and what hours they are open.

Frequently Asked Questions

Can I explore for Medicare before I turn 65?

What if I am still working at 65 — do I have to explore for Medicare?

You do not have to explore right away if you have health insurance through your employer. However, you should contact your employer's benefits office to ask about a special enrollment period, which may extend your important date. If you may have access to, keep written confirmation from your employer in case you need it later.
