How to Enroll in Medicare Online, Step by Step

Woman completing Medicare application online

You can enroll in Medicare online at ssa.gov, the Social Security Administration’s website. People 65 or older can apply there for Parts A and B, or for Part A only. You sign in to (or create) a personal my Social Security account, answer questions about yourself and your work and health coverage history, and submit. Most people finish in one sitting. You can also call, or visit an office, if you would rather not use a computer.

This guide covers who can apply online, what to have on hand, when to apply so your coverage starts on time, and what changes if you are self-employed, still working, or not collecting Social Security. We are a local agency in Bend, Oregon, and we help Central Oregon neighbors through this every week.

TL;DR

  • Apply for Original Medicare (Parts A and B) at ssa.gov. Medicare itself does not take the application. Social Security does.
  • Your Initial Enrollment Period is seven months: three months before your 65th birthday month, the birthday month, and three months after.
  • You do not need to be collecting Social Security to enroll. You do need your Social Security number and some work and health plan history.
  • If you or a spouse still work for an employer with group coverage, you may be able to delay Part B without a penalty. Self-employed people usually cannot use that route.
  • Medicare Advantage, Part D and Medigap are separate decisions made with private carriers, after or alongside your Part A and B application.

Which website do you use to enroll in Medicare?

The site is Social Security’s. The page to start from is the Sign up for Medicare page at SSA, where you choose “Apply online.” Social Security manages enrollment in Parts A and B, even though Medicare.gov is where you later compare plans.

A common point of confusion: your Medicare account and your Social Security account are different things. You use your my Social Security account to submit the application. Later, you create a separate login at Medicare.gov to view claims and compare plans.

Applicants are directed to create or sign in to a my Social Security account. If you cannot do that, the same SSA publication says you can continue your application online without one.

Be wary of look-alike sites. The government application is free, and the address ends in .gov.

Do you need to enroll at all? Automatic enrollment

Not everyone applies. People who already receive Social Security or Railroad Retirement Board benefits are automatically entitled to Parts A and B starting the first day of the month they turn 65. Your card arrives by mail.

If you are not drawing benefits yet, you must apply. That is the situation for most people who keep working past 65 or who delay Social Security for a larger check. Eligibility itself also covers people under 65 with a disability after 24 months of SSDI, or with ESRD or ALS.

What you need before you start

Gather these first, and the application goes quickly. According to SSA, you generally need your Social Security number, where you were born, and the start and end dates of current group health plans and any plans you had after age 65.

If you are not receiving Social Security benefits, expect more questions. Applicants in that position should be ready to give details about past employment, military service before 1968, and current or former spouses. A short checklist:

  • Social Security number and date and place of birth
  • Your employer’s name and address, and your dates of employment
  • Dates your current or past group health coverage began and ended
  • Spouse details, including marriage dates, if you may qualify through a spouse’s record
  • Military service dates if before 1968
  • Your bank details if you want Part B premiums handled in a particular way

Have your current insurance card nearby. If you are covered at work, ask HR for the exact coverage dates before you start.

Step-by-step: applying online

  1. Confirm you are in your window. Check your Initial Enrollment Period dates (next section) so you are not applying too early or too late.
  2. Go to the SSA sign-up page. Choose Apply online for Medicare.
  3. Sign in or create your my Social Security account. If account setup stalls, use the option to continue without one.
  4. Answer the questions. You will be asked whether you want Part A, Part B, or both, and about your work and health coverage history.
  5. Submit and save your confirmation. Keep it. You can often stop and return to a saved application rather than starting over.
  6. Watch your mail. Your Medicare card and a notice about your coverage dates follow.
  7. Choose how you will fill the gaps. Original Medicare does not stand alone for most people. You will pick a Medicare Advantage plan or a Medigap policy, and usually a Part D drug plan.

When to enroll and when coverage starts

Timing is where most costly mistakes happen, so this part deserves your attention.

Your Initial Enrollment Period

The IEP lasts seven months: it begins three months before the month you turn 65, includes your birth month, and ends three months after. Say your birthday is in June. Your window opens March 1 and closes September 30.

Seven-month Medicare enrollment period timeline

When coverage begins

Premium-free Part A starts the month you turn 65 if you apply within six months. For Part B, coverage starts the next month if you enroll in your birthday month or in the three months after. Signing up in the three months before your birthday month lets you line coverage up with your birthday month.

When you apply What it means for Part B
Before your birthday month (within the IEP) Coverage can begin when you turn 65
Birthday month or the 3 months after Coverage begins the following month
After your IEP ends You wait for the General Enrollment Period

The practical advice: apply in the first three months of your window. That way you are covered the month you turn 65 and not scrambling.

The General Enrollment Period

Miss your IEP and you have a second chance, but a slower one. The General Enrollment Period runs January 1 through March 31 each year, with coverage starting the month after you enroll. Waiting can also bring late penalties, which is why we prefer people not drift past their IEP unless they have qualifying work coverage. Our guide to Medicare enrollment periods lays out every window side by side.

Enrolling in Medicare without Social Security benefits

This is one of the most searched questions, and the answer is reassuring: collecting Social Security and being enrolled in Medicare are separate. Social Security simply processes the Medicare paperwork. If you are not yet taking benefits, you apply for Medicare yourself, using the same online application or by phone.

A few practical notes:

  • You will be asked for more history than someone already receiving benefits, as listed above.
  • Premium-free Part A depends on your work record, or a spouse’s, so the application checks it.
  • Applying for Medicare does not start your retirement benefits. They are a separate application.

Our Medicare eligibility page walks through who qualifies and how.

If you are self-employed or still working

Working past 65 changes the plan, and whether you should delay Part B depends on the kind of coverage you have.

Coverage through a current employer

People covered by a group health plan based on their own or a spouse’s current employment may sign up for Part B during a Special Enrollment Period without a late enrollment penalty. Employer size matters too. If the employer has fewer than 20 employees and is not part of a multi-employer or multiple-employer plan, Medicare pays first. That means a small-company plan may not be enough on its own once you are 65. Our post on the 20 employee rule in Oregon explains how to check.

When the job coverage is about to end, Medicare Interactive suggests talking with your HR department one to two months beforehand so there is no gap. See also our guide to Medicare special enrollment.

COBRA and retiree coverage

These do not count as current employment coverage. People with them should generally enroll during their initial enrollment period to avoid late penalties. We cover this in detail in Medicare and COBRA.

Self-employed

If you run your own business, you are typically not covered by a group plan through current employment, so the safest path is usually to enroll in Part B during your IEP. Individual marketplace or private plans are generally not the kind of employer coverage that opens the Special Enrollment Period. Because your facts matter (a spouse’s employer plan, for example, can change the answer), run your situation by someone before you decide to wait. A spouse’s job coverage is addressed in avoiding spouse Medicare gaps in Oregon.

After you apply: checking status and other ways to apply

You can check your application status online by logging in to your my Social Security account or by calling 1-800-772-1213. You can also call SSA or schedule an appointment at a local Social Security office for status.

If online does not work for you, the same program is available by phone or in person. Bend residents can ask SSA for an appointment at the nearest office. If you prefer to sit at a table with someone, we meet in person around Central Oregon or remotely.

What comes next: Medigap, Advantage, Part D

Applying on ssa.gov gets you Original Medicare. The rest is private coverage you select:

Once your coverage is in place, many families also start thinking ahead about paying for home care, since planning early gives you more choices.

Our perspective

Most of the stress people feel about Medicare is not the online form. The form takes a short sitting. The stress comes from the decisions around it: whether to take Part B now, which kind of plan to build on it, and which deadlines apply to your particular situation.

We are a local Bend agency, and we approach this as educators first. A free consultation is meant to leave you understanding your options and your dates, whether or not you enroll through us. We would rather you apply on ssa.gov with confidence than click through and hope.

One thing we especially like to look at is Medigap. Oregon has a birthday rule that lets current Medigap holders shop for an equal or lesser plan around their birthday, and many people paying more than they need to have never heard of it. If that sounds like you, bring your current policy and we will go through it with you.

Get a second opinion on your enrollment

If you are within a few months of 65, or you are working and unsure about Part B, we can help you time it right. Mountaintop Insurance offers free in-person and remote consultations for Central Oregon residents, covering Parts A, B, C and D, Medigap, and dental and vision.

Common mistakes to avoid

  • Waiting past your IEP without qualifying coverage. This can mean a gap and late penalties. Our list of common enrollment mistakes at 65 goes deeper.
  • Assuming COBRA counts as work coverage. It does not for this purpose.
  • Skipping the plan choice. Part A and B alone leave out-of-pocket exposure and no drug coverage.
  • Never reviewing. Needs and plans change yearly, which is why we offer annual Medicare plan reviews.

FAQ

Can I really sign up for Medicare entirely online?

Yes, for Original Medicare. Parts A and B, or Part A only, can be applied for through your my Social Security account at ssa.gov. Plans like Advantage, Part D and Medigap are enrolled in separately through carriers or an agent.

Do I have to be receiving Social Security to enroll?

No. If you are not receiving benefits you apply for Medicare on your own, and you should expect to answer more questions about your work and spouse history. Those already receiving benefits are enrolled automatically in Parts A and B when they turn 65.

I’m self-employed. When should I apply?

Most self-employed people should apply during their seven-month Initial Enrollment Period, since they usually lack the current-employment group coverage that allows delay. If a spouse has employer coverage, ask us or your plan administrator before deciding.

What if I miss my Initial Enrollment Period?

You can enroll during the General Enrollment Period from January 1 through March 31, with coverage starting the month after you sign up. A Special Enrollment Period may apply if you had qualifying employer coverage.
