The standard Medicare age is 65

You become may be able to access for Medicare at age 65, regardless of your employment status or income. This is the age set by federal law, and it applies to all U.S. citizens and permanent residents who have lived in the country for at least five years.

You do not have to retire at 65 to get Medicare. You can keep working and enroll in Medicare at the same time. Your work status does not change your may be able to access date.

Key Takeaways

  • You become may be able to access for Medicare on the first day of the month you turn 65, or the month after, depending on your birthday.
  • You must enroll during your Initial Enrollment Period, which runs for seven months centered on the month you turn 65—three months before, the month of, and three months after.
  • If you delay enrollment past your Initial Enrollment Period without a valid reason, you may pay higher premiums for the rest of your life.
  • Some people under 65 can get Medicare if they receive Social Security disability benefits or have end-stage renal disease or ALS.
  • You enroll through Medicare.gov, by phone at 1-800-MEDICARE, or at your local Social Security office.

When your coverage actually starts

Your Medicare coverage begins on the first day of the month you turn 65. If your birthday is on the first of the month, coverage starts that day. If your birthday is any other day, coverage starts on the first day of the following month.

For example, if you turn 65 on March 15, your coverage begins April 1. If you turn 65 on April 1, your coverage begins that same day.

Your Initial Enrollment Period explained

You have a seven-month window to enroll in Medicare without penalty. This window is called your Initial Enrollment Period, and it runs for three months before the month you turn 65, the month you turn 65, and three months after.

If you turn 65 in June, your Initial Enrollment Period runs from March through September. You can enroll anytime during those seven months, and your coverage will start on the first day of the month you turn 65 (or the month after, depending on your birthday).

If you enroll after your Initial Enrollment Period ends, you may face a permanent penalty on your premiums. This penalty applies to Part B and Part D coverage and stays with you for life, even if you switch plans later.

Medicare before age 65

Most people cannot get Medicare until 65, but three groups can enroll earlier. If you have received Social Security Disability Insurance (SSDI) for 24 months, you become may be able to access at any age. If you have end-stage renal disease (permanent kidney failure requiring dialysis or transplant), you can enroll regardless of age. If you have ALS (amyotrophic lateral sclerosis), you can enroll when ready without waiting.

These are the only exceptions to the age 65 rule. If you fall into one of these categories, contact Social Security or Medicare directly to learn about your enrollment window, because it differs from the standard Initial Enrollment Period.

How to enroll when you turn 65

You can enroll through three channels: online at Medicare.gov, by phone at 1-800-MEDICARE (1-800-633-4227), or in person at your local Social Security office. The Social Security office route is often fastest if you need to enroll quickly, because staff can process your process on the spot.

When you enroll, have your Social Security number and information about any current health coverage ready. If you are still working and covered by an employer plan, tell Medicare that when you enroll—it may affect which parts of Medicare you need to sign up for right away.

What happens if you miss your enrollment window

If you do not enroll during your Initial Enrollment Period and you do not have a valid reason for the delay, you will pay a permanent penalty when you finally do enroll. For Part B, the penalty is 10 percent of the standard premium for each full year you were may be able to access but not enrolled. For Part D (prescription drug coverage), the penalty is 1 percent of the national average premium for each month you were without coverage.

These penalties do not go away. Even if you switch plans or move to a different state, the higher premium follows you. The only way to avoid the penalty is to enroll during your Initial Enrollment Period or to have a valid reason for late enrollment, such as coverage through an active employer or membership in a union health plan.

Special enrollment periods and exceptions

If you miss your Initial Enrollment Period but have a valid reason, you may may have access to for a Special Enrollment Period that lets you enroll without penalty. Valid reasons include losing employer coverage, moving to a new state, or changes in your family status.

You must enroll during the Special Enrollment Period, which is usually eight months long. Contact Medicare directly to find out whether your situation qualifies and when your Special Enrollment Period window closes. Do not assume you have time—the window is shorter than the Initial Enrollment Period, and missing it means paying the permanent penalty.

Frequently Asked Questions

Can I get Medicare before I turn 65?

Only if you receive Social Security disability benefits for 24 months, have end-stage renal disease, or have ALS. Otherwise, you must wait until 65. Contact Social Security to find out your exact enrollment date if you fall into one of these categories.

What if I'm still working at 65?

You can enroll in Medicare and keep working. If your employer has 20 or more employees and you are covered by their health plan, you may not need to enroll in Part B right away—tell Medicare about your coverage when you enroll so you do not pay penalties later.

Do I have to enroll in all parts of Medicare at 65?

You must enroll in Part A (hospital insurance) and Part B (medical insurance) during your Initial Enrollment Period to avoid penalties. Part D (prescription drug coverage) has its own enrollment rules. Part C (Medicare Advantage) is optional.

What if my birthday is on the first of the month?

Your Medicare coverage starts on your birthday itself, not the following month. Your Initial Enrollment Period still runs three months before, the month of, and three months after your birthday.

Can I delay Medicare enrollment without penalty?

Yes, if you have employer coverage through your job or your spouse's job and your employer has 20 or more employees. You must tell Medicare about this coverage when you eventually enroll. Without this exception, delaying past your Initial Enrollment Period costs you a permanent premium increase.
