You become may be able to access for Medicare at 65, or earlier if you have been on Social Security Disability Insurance for 24 months, or if you have end-stage renal disease or ALS

The most common path is turning 65. You do not have to be retired, and you do not have to be poor. If you were born on the 1st of any month, your coverage starts the month you turn 65. If you were born on any other day, coverage starts the first day of the month after you turn 65.

If you have been receiving Social Security Disability Insurance (SSDI) for 24 consecutive months, you move to Medicare automatically at that point, regardless of your age. If you are on SSDI and approaching that 24-month mark, Social Security will contact you before the switch happens.

Two smaller groups become may be able to access before 65: people with end-stage renal disease (permanent kidney failure requiring dialysis or transplant) and people with ALS (amyotrophic lateral sclerosis). Both can enroll when ready upon diagnosis, with no waiting period.

The enrollment window: when you must sign up

Your Initial Enrollment Period is seven months long: it starts three months before the month you turn 65 and ends three months after. If you turn 65 in June, your window opens in March and closes in September.

You do not have to enroll on the day you turn 65. You can enroll any time during those seven months. However, your coverage start date depends on when you enroll. If you enroll in the month you turn 65 or earlier, coverage starts the month you turn 65. If you enroll after that month, coverage starts the first day of the month after you enroll.

If you miss this window and do not have other may have access to insurance, you will pay a permanent 10 percent penalty on Part B premiums for as long as you are on Medicare. The same penalty applies to Part D (prescription drug coverage). These penalties do not go away.

When you can delay enrollment without penalty

You can miss your Initial Enrollment Period without penalty if you have creditable coverage — employer insurance, union coverage, or TRICARE — through work or a spouse's work. You must enroll within eight months of losing that coverage, or the penalty kicks in.

Creditable coverage means the insurance is at least as good as Medicare Part B. Your employer or insurance company can tell you whether your plan qualifies. If you are unsure, you can ask Medicare directly by calling 1-800-MEDICARE.

If you are still working and your employer has 20 or more employees, you can also delay Part B enrollment without penalty. You must enroll within eight months of retiring or losing the employer coverage, whichever comes first.

Citizenship and residency requirements

You must be a U.S. citizen or a permanent resident (green card holder) to be may be able to access for Medicare. If you are a permanent resident, you must have lived in the United States for at least five consecutive years.

Permanent residents who have lived here fewer than five years cannot enroll, even if they turn 65. Once you reach the five-year mark, you become may be able to access and your enrollment window opens.

If you are not yet a permanent resident but are working toward that status, contact Social Security to confirm your may be able to access before your 65th birthday. The rules can vary based on your visa type and immigration status.

What happens if you are still working at 65

You must enroll in Medicare at 65 even if you are still working and have employer insurance. However, you can delay Part B enrollment without penalty if your employer has 20 or more employees and you are covered under their health plan.

Part A (hospital insurance) has no premium for most people, so there is no penalty for delaying it. You can enroll in Part A only and keep your employer coverage for doctor visits and other services. When you retire or lose the employer plan, you then enroll in Part B.

If your employer has fewer than 20 employees, you must enroll in both Part A and Part B at 65, even if you have their insurance. Employer plans become secondary to Medicare in this situation.

Special enrollment periods: life changes that reopen your window

If you miss your Initial Enrollment Period, you may still enroll without penalty if you experience certain life events. These are called Special Enrollment Periods. The most common are losing employer coverage, moving out of your insurance plan's service area, or having a change in your immigration status.

You typically have two months from the may have access to event to enroll. For example, if you retire on June 15 and lose employer coverage, you have until August 15 to enroll in Medicare without penalty.

Not all life changes may have access to. Divorce, death of a spouse, and changes in income do not reopen your enrollment window. If you are unsure whether your situation qualifies, contact Social Security or Medicare before your important date passes.

How to check your may be able to access status

You can create an account on ssa.gov (Social Security Administration) to see your earnings record and confirm your may be able to access. You will need your Social Security number, email address, and a phone number.

You can also call Social Security at 1-800-772-1213 (TTY 1-800-325-0778) to confirm your may be able to access and ask about your enrollment window. Have your Social Security number ready.

If you are on SSDI and approaching your 24-month mark, Social Security will send you a notice in the mail. Read it carefully — it will tell you your exact Medicare start date and what you need to do next.
