Who Is Eligible for Medicare?

You are eligible for Medicare Part A and Part B at age 65 if:

• You are a U.S. citizen or permanent legal resident who has lived in the U.S. for five continuous years
  
  
• You or your spouse have worked long enough to be eligible for Social Security or Railroad Retirement benefits
  
  
• You or your spouse are government employees or retirees who have not paid into Social Security but have paid Medicare payroll taxes

You can meet Medicare eligibility under 65 if you:

• Have been receiving Social Security disability benefits or certain Railroad Retirement Board disability benefits for at least 24 months
  
  
• You have ALS (amyotrophic lateral sclerosis or Lou Gehrig's disease)
  
  
• You have End-Stage Renal Disease (ESRD) and you or your spouse have paid Social Security taxes for a certain length of time

When to Enroll in Medicare

Some People Get Medicare Automatically

You may be automatically enrolled for Medicare Part A and Part B benefits if you are age 65 and already receive Social Security or Railroad Retirement benefits.

If you are under age 65, you may be automatically enrolled if you have received Social Security or Railroad Retirement disability benefits for 24 calendar months.

If you are automatically enrolled, you will receive your red, white and blue Medicare benefits card in the mail. Your Medicare coverage will begin either on the first day of the month during which you turn 65 or on the first day of your 25^th month receiving disability benefits.

If you are under 65 and have ALS/Lou Gehrig’s disease, your Medicare benefits will start the same month your disability benefits begin — there’s no 24-month waiting period.

Manual Medicare Enrollment

You may need to manually sign up for Medicare if one of the following circumstances apply to you:

• You are approaching your 65th birthday, meet Medicare eligibility requirements and do not currently receive Social Security or Railroad Retirement board benefits
  
  
• You are under 65 and eligible for Medicare because you have ESRD
  
  
• You are over age 65 and you did not enroll in Medicare when you were first eligible

Veterans who receive VA coverage and are eligible for Medicare can also consider enrolling in Medicare Part A and Part B. If you have VA benefits as well as Medicare coverage, your options for care and your coverage net can be widened. Your qualified care would be covered under Medicare Part A and/or Part B, even if you go to a non-VA hospital or doctor.

Medicare Initial Enrollment Period (IEP)

The earliest time you can enroll in Original Medicare, a Medicare Advantage plan or a Medicare Part D prescription drug plan is during your Medicare Initial Enrollment Period (IEP).

Your Initial Enrollment period lasts for seven months:

• It begins three months before you turn 65
• It includes your birth month
• It extends for another three months after your birth month

If you are under 65 and qualify for Medicare due to disability, the 7-month period is based around your 25th month of disability benefits.

Medicare General Enrollment Period

If you don't sign up during your Initial Enrollment Period and if you aren't eligible for a Special Enrollment Period, the next time you can enroll in Medicare is during the Medicare General Enrollment Period.

The General Enrollment Period lasts from January 1 to March 31 each year.

You can only sign up for Part A and/or Part B during this period, and your coverage starts on July 1. You may have to pay a late enrollment period for Part A and/or Part B, as detailed below.

Part B Late Enrollment Penalty: If you do not enroll in Medicare Part B during your Initial Enrollment Period but decide to enroll later in life, you will have to pay a late enrollment penalty. Your Part B monthly premium could go up 10 percent for each 12-month period that you were eligible for Part B but didn't sign up. You pay the Part B late enrollment penalty for the rest of your life as long as you remain enrolled in Part B.

Medicare Advantage Plan Enrollment

When you’re eligible to enroll in Original Medicare, you also become eligible to enroll in a Medicare Advantage (Medicare Part C) plan. You need to enroll in Original Medicare before you enroll in Medicare Advantage. Before enrolling in a plan, it may be a good idea to compare Medicare Advantage quotes.

• 99 percent of 2024 Medicare Advantage plans include additional vision benefits for eye exams and eyeglasses/contacts, and 98 percent of plans offer fitness benefits such as SilverSneakers membership. 97 percnet of plans offered hearing exams and hearing aids and/or dental benefits.²
  
  
• Every year, Medicare evaluates plans based on a 5-star rating system. According to the Centers for Medicare & Medicaid Services (CMS), the average star rating for a Medicare Advantage plan in 2024 is 4.04.³
  
  
• Nearly three out of four MA-PD plan beneficiaries are enrolled in a 2024 plan rated 4 or more stars.³

To be eligible for Medicare Part C, you must already be enrolled in Part A and Part B.

If you are interested in joining a Medicare Advantage plan, you typically can only do so during specific times of the year.

The first time you may be able to enroll is during your Medicare Initial Enrollment Period, as outlined above.

If you sign up for a Medicare Advantage plan during your Initial Enrollment Period, you can change to another Medicare Advantage plan or switch back to Original Medicare within the first 3 months that you have Medicare.

A licensed insurance agent can help you compare plans options available where you live.

Medicare Part D Prescription Drug Plan Enrollment

When you’re eligible to enroll in Original Medicare, you also become eligible to enroll in a Medicare Part D prescription drug plan.

If you want Medicare prescription drug coverage, you typically have two options:

• Enroll in a Medicare Advantage plan that includes Part D prescription drug coverage, Medicare Part A hospital insurance and Part B medical insurance combined into a single plan
  
  
• Enroll in a Medicare Part D standalone prescription drug plan (PDP) that can be paired with other insurance such as Original Medicare (Parts A and B), Medicare Supplement (Medigap) plans or Medicare Advantage plans that don't include drug coverage

In 2024, 23 million Medicare beneficiaries were enrolled in a standalone Part D Medicare drug plan.⁴

Fall Medicare Open Enrollment Period

If you choose not to sign up for a Medicare Advantage plan or stand-alone Medicare prescription drug coverage during your Initial Enrollment Period, you can also enroll in a Medicare Advantage plan during the annual Fall Medicare Open Enrollment Period.

The 2024 Medicare Open Enrollment period is also called the Medicare Annual Election Period (AEP).

This period runs from October 15 to December 7 every year.

During the Fall Medicare Open Enrollment Period for Medicare Advantage and Medicare prescription drug coverage, you can:

• Enroll in, make changes to or disenroll from a Medicare Advantage plan (Medicare Part C)
  
  
• Enroll in, make changes to or disenroll from a Medicare Prescription Drug plan (Medicare Part D)

Plan changes you make during the 2024 Medicare Fall Annual Enrollment Period go into effect January 2025.

Is Medicare Open Enrollment Still Open?

Yes, the Medicare Open Enrollment Period is happening right now and will run until December 7, 2024.

During this time, you may be able to drop, switch or enroll in a Medicare Advantage or Medicare Part D prescription drug plan for the 2025 plan year.

Medicare Advantage Open Enrollment Period

The Medicare Advantage Open Enrollment Period starts January 1 and ends March 31 every year. During this period, you can switch Medicare Advantage plans or leave a Medicare Advantage plan and return to Original Medicare.

Medicare Special Enrollment Period (SEP)

Depending on your circumstances, you may also qualify for a Special Enrollment Period (SEP).

Medicare Special Enrollment Periods can happen at any time during the year. You may qualify for a Special Enrollment Period for a number of reasons, which can include:

• You moved to a new area that is outside of your current Medicare Advantage plan's service area
• You left your employer coverage
• Medicare ended your current Medicare Advantage plan's contract

A licensed insurance agent can help you find out if you qualify for a Medicare Special Enrollment Period.

Medicare Supplement Insurance (Medigap) Enrollment

If you have Original Medicare and would like to enroll in a Medicare Supplement Insurance plan (also called Medigap), the best time to sign up is during your six-month Medigap Open Enrollment Period.

• Your Medigap Open Enrollment Period starts as soon as you are age 65 or older and are enrolled in Medicare Part B.
  
  
• Insurance companies cannot deny you Medigap coverage or charge you a higher fee for pre-existing health conditions if you apply for Medicare Supplement Insurance during your Medigap Open Enrollment Period.

If you don’t sign up for a Medigap plan during your Medigap Open Enrollment Period, you may still be able to buy one at any time.

Insurance companies can take your health into consideration when setting your premiums or deciding whether or not to offer you coverage, however.

You must be enrolled in Medicare Part A and Part B in order to buy a Medigap plan.

Medigap and Medicare Advantage plans are very different, and you cannot be enrolled in a Medigap plan and a Medicare Advantage plan at the same time.
