Key Takeaways

  • People who choose early retirement through Social Security and those who get Social Security Disability (or Railroad Retirement benefits) are automatically enrolled in Medicare Parts A and B. 

  • Do you have to sign up for Medicare if you’re not automatically enrolled? Yes—all other people need to consider their options and make choices during the Initial Enrollment Period (the three months before, the month of, and the three months after your 65th birthday). 

  • Can you decline Medicare coverage? Yes; however, even if you are still working, make sure you understand your Medicare options and what it means to delay enrollment. 

Medicare is a federal health insurance program for older Americans and people with certain disabilities. At what age do you qualify for Medicare? In most cases, the minimum age for Medicare is 65. People who are younger than age 65 may also qualify in certain circumstances.  

It’s important to know that qualifying for Medicare is not automatic. Some people will get coverage automatically, while others must apply. Find out if you’re eligible—and how to apply if you are.

What are the rules for applying to Medicare?

If you’re wondering, “Am I qualified for Medicare?”, the guidelines below can help you make a determination.

If you’re 65 or older, you’re eligible for full benefits if:

  • You’re a U.S. citizen or permanent legal resident, and you’ve lived in the country for a minimum of 5 years.
  • You (or your spouse) are a current or retired government employee who has paid Medicare payroll taxes while employed.
  • You collect Social Security or railroad retirement benefits. Or, you’ve worked enough years to qualify for these benefits even if you’re not receiving them.

If you’re younger than 65, you’re eligible for full benefits if:

  • You have permanent kidney failure requiring dialysis or a kidney transplant and you (or your spouse) have paid Social Security taxes for a defined amount of time.
  • You have amyotrophic lateral sclerosis (ALS).
  • You’re collecting a disability pension from the Railroad Retirement Board (you must also meet specific conditions in addition to this).
  • You’ve qualified for Social Security disability benefits (SSDI) for a period of at least 24 months.

When deciding about other Medicare options, including Medicare Advantage, Medigap and Part D, be sure you make a choice based on your personal situation. You can talk to a licensed Medicare enrollment specialist or your local State Health Insurance Assistance Programs (SHIPs) for personalized recommendations.  

Automatic Enrollment: If already receiving Social Security retirement (because you chose early retirement after age 62), or you receive Social Security Disability Benefits (or Railroad Retirement benefits) when you turn 65:

  • Medicare Parts A & B (Original Medicare) enrollment is automatic,
  • A “Welcome to Medicare” packet and Medicare card will arrive in the mail from the Social Security Administration about 3 months before 65th birthday.

Must apply: Do you have to sign up for Medicare in certain situations? If you did not choose early retirement between the ages of 62 and 65, you must contact Social Security to apply. You can enroll during your Initial Enrollment Period (the three months before, the month of, and the three months after your 65th birthday). Upon enrollment, Social Security will send a "Welcome to Medicare" packet that includes a Medicare card.

Three ways to Apply for Medicare Parts A and B

There are additional options for your health and prescription drug coverage.

  • Part C, or Medicare Advantage plans. You can choose a Medicare Advantage plan in place of Original Medicare. The Medicare Advantage plans include Original Medicare and usually your prescription drug plan. Medicare Advantage plans are run by private health insurance companies. Are Medicare Advantage plans worth it? While some Advantage plans offer greater plan flexibility and long-term savings, some can involve additional costs. Be sure to understand the pros and cons before making a decision.
  • Medigap. People who choose Original Medicare (for Parts A and B coverage) usually enroll in a Medigap plan to address the “gaps” in coverage. Medigap plans are also run by private companies who contract with Medicare. Plan options are standardized across most states.
  • Many people wonder, “Does Medicare pay for prescriptions?” That is where Part D comes in. People who choose Original Medicare generally need to also chose a Part D plan for prescription drug coverage. If you do not enroll in Part D when you are initially eligible (and if you do not have other creditable drug coverage), you can face a penalty when you do enroll late.

To join an additional Medicare plan (Part C, Part D or Medigap), start by comparing local plans. Before enrolling in any of these plans, be prepared to provide Medicare number and Part A and/or Part B coverage start date. This information can be found on the Medicare card. Enrollment can be done a few ways:
