Medicare eligibility and enrollment

Eligibility

Who is eligible for Original Medicare (Part A & Part B)

Medicare is a government health insurance program for Americans who are 65 or older and younger people
who have certain disabilities and receive Social Security benefits.

Medicare was first created in two parts, Part A (hospital coverage) and Part B (coverage for doctor visits and outpatient care).
Together, they’re called Original Medicare.

Original Medicare is available to people who:

Are age 65 or older
Are a U.S. citizen or have been a legal resident for five consecutive years
Are eligible for benefits from Social Security or the Railroad Retirement Board

Are under age 65 and are permanently disabled and have received Social Security Disability for two years
Have end-stage renal disease requiring ongoing dialysis or a transplant
Have paid into Medicare through payroll taxes during your (or your spouse’s) working years

When to enroll

Enroll at the right time

Your Initial Enrollment Period into Original Medicare is a seven-month window — from three months before your 65th birthday month to three months after your 65th birthday month. Coverage can begin as soon as the first day of the month you turn 65.

Enrollment order

You must enroll in Original Medicare Part A and Part B before you enroll in a Medicare Advantage, Medicare Cost, Medicare Supplement (Medigap) or Part D prescription drug plan.

Social Security benefits

If you already receive Social Security benefits, you will automatically be enrolled in Medicare Part A and Part B.

Disabled and under 65

If you are disabled and under 65, you will get Part A and Part B automatically after you’ve received disability benefits from Social Security for 24 months.

Working past 65

If you or your spouse plan to work past age 65, you may not need to enroll in Medicare when you turn 65.

Coverage effective date

If you apply for Medicare prior to your Part A and Part B effective date, your coverage will take effect on your Part A and Part B effective date.

If you apply for Medicare after your Part A and Part B effective date, your coverage will be effective the 1st of the month following the date of receipt.
