If you are not yet on Social Security, you need to sign up for Medicare yourself during your enrollment window.

The only exception to the age 65 rule is if you have been receiving Social Security Disability Insurance (SSDI) for 24 months, or if you have end-stage renal disease or ALS (amyotrophic lateral sclerosis). In those cases, you may be may be able to access before 65. Otherwise, age 65 is the threshold.

  • You are may be able to access for Medicare at age 65, and enrollment is automatic if you are already on Social Security retirement benefits.
  • If you are not on Social Security, you must sign up for Medicare yourself during the seven-month window that includes your 65th birthday month.
  • You can enroll as early as three months before you turn 65 and as late as three months after, but waiting past your birthday month may trigger a permanent penalty on your premiums.
  • People under 65 who receive SSDI for 24 months, or who have end-stage renal disease or ALS, may be may be able to access before reaching 65.
  • Medicare has four parts (A, B, C, and D), and the parts you need depend on your situation and coverage choices.

When to enroll if you are not on Social Security

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

You should enroll during this window even if you do not plan to use Medicare right away. If you wait past the end of your window, you may face a permanent increase to your Part B premium (the part that covers doctor visits and outpatient care). The penalty is 10 percent of the standard premium for each full year you were late, and it stays with you for life.

You can enroll online through Medicare.gov, by phone at 1-800-MEDICARE, or in person at your local Social Security office. Have your Social Security number and proof of citizenship or legal residency ready.

Automatic enrollment if you receive Social Security

If you are already collecting Social Security retirement, spousal, or survivor benefits, Medicare signs you up automatically. You do not have to do anything. About three months before your 65th birthday, you will receive a notice in the mail explaining your coverage and what happens next.

You will be enrolled in Medicare Part A (hospital insurance) and Part B (medical insurance) automatically. If you do not want Part B, you can decline it, but you must do so in writing before your coverage starts. Keep in mind that declining Part B when you first become may be able to access can result in a permanent premium penalty if you enroll later.

Medicare Parts A, B, C, and D explained

Part A covers hospital stays, skilled nursing care, hospice, and some home health services. Most people do not pay a monthly premium for Part A because they or their spouse paid Medicare taxes while working. You pay a deductible when you use hospital services.

Part B covers doctor visits, outpatient care, medical equipment, and preventive services. It has a monthly premium (the amount changes each year) and a yearly deductible. You typically pay 20 percent of the cost after you meet the deductible.

Part C, also called Medicare Advantage, is an alternative to Parts A and B offered by private insurance companies. It bundles hospital and medical coverage and usually includes prescription drug coverage. Many Part C plans have lower out-of-pocket costs but restrict you to a specific network of doctors.

Part D covers prescription drugs. You can add it to Original Medicare (Parts A and B), or it may be included in your Part C plan. It has a monthly premium and a yearly deductible that varies by plan.

What happens if you work past 65

You can keep working after 65 and delay enrolling in Medicare without penalty, but only if you are covered by a group health plan through your employer and you are actively employed. You must enroll in Medicare within eight months of the date your employment ends or your group coverage stops, whichever comes first. If you miss this important date, you may face a permanent premium penalty.

If you are self-employed or your employer does not offer health coverage, you should enroll in Medicare at 65 even if you are still working. The same enrollment window and penalty rules explore.

Special situations: disability and chronic illness

If you have been receiving SSDI for 24 consecutive months, you become may be able to access for Medicare at that point, regardless of your age. Your coverage begins the 25th month of your disability benefits. You do not need to wait until 65.

If you have end-stage renal disease (permanent kidney failure requiring dialysis or transplant) or ALS, you may be may be able to access for Medicare regardless of age. For end-stage renal disease, may be able to access begins the month you start dialysis or the month you have a kidney transplant, whichever comes first. For ALS, you are may be able to access when ready upon diagnosis. Contact Social Security or Medicare directly to confirm your may be able to access in these situations.

How to prepare before your 65th birthday

Start preparing about four months before you turn 65. Gather your Social Security number, proof of citizenship or legal residency, and information about any current health coverage you have. If you are not yet on Social Security, create an account on ssa.gov or visit your local Social Security office to understand your retirement benefit amount.

Review the Medicare plan options available in your area. Medicare.gov has a plan comparison tool that shows you what Part C and Part D plans are offered where you live, what they cost, and which doctors and pharmacies are in their networks. Comparing plans before your enrollment window opens means you can make a choice quickly once you are may be able to access.

If you have questions about your specific situation, call 1-800-MEDICARE. Representatives can walk you through your options and help you understand what you will pay under different plans.
