If you’re looking to enroll in Medicare this year, it’s important to understand the Medicare Part B eligibility requirements.

You’re automatically eligible to enroll in Medicare Part B when you turn 65. You’re also eligible to enroll under special circumstances, such as if you have a diagnosis of a disability or end-stage renal disease.

In this article, we’ll explore who is eligible for Medicare Part B, how to enroll, and important Medicare deadlines to take note of.

Medicare Part B is a health insurance option that becomes available for people in the United States once they reach age 65. However, there are some special circumstances under which you may qualify to enroll in Medicare Part B before the age of 65.

Below, you will find the eligibility requirements for enrolling in Medicare Part B.

You’re 65 years old

You automatically qualify for Medicare Part B once you turn 65 years old. Although you’ll need to wait to use your benefits until your 65th birthday, you can enroll:

  • 3 months before your 65th birthday
  • on your 65th birthday
  • 3 months after your 65th birthday

You have a disability

If you have a disability and are receiving disability payments, you’re eligible to enroll in Medicare Part B even if you’re not 65. According to the Social Security Administration, qualifying disabilities may include:

  • sensory disorders
  • cardiovascular and blood disorders
  • digestive system disorders
  • neurological disorders
  • mental disorders

You have ESRD or ALS

If you have been given a diagnosed of end stage renal disease (ESRD) or amyotrophic lateral sclerosis (ALS), you’re eligible to enroll in Medicare Part B even if you’re not yet 65 years old.

Medicare Part B covers the outpatient diagnosis, treatment, and prevention of medical conditions.

This includes visits to the emergency room, as well as preventive healthcare services like doctor’s visits, screening and diaganostic tests, and some vaccinations.

Medicare Part B is just one option available to Medicare beneficiaries. However, the best coverage for you will depend entirely on your personal medical and financial situation.

Other coverage options that may be used instead of or in combination with Medicare Part B include Medicare Part C, Medicare Part D, and Medigap.

Medicare Part C

Medicare Part C, also known as Medicare Advantage, is an option offered by private insurance companies for Medicare beneficiaries.

Research has found Medicare Advantage to be a popular Medicare option, with almost one-third of beneficiaries choosing an Advantage plan over traditional Medicare.

To enroll in Medicare Part C, you must already be enrolled in parts A and B.

Under a Medicare Advantage plan, you’ll generally be covered for:

If you have a Medicare Part C plan, it takes the place of original Medicare.

Medicare Part D

Medicare Part D is an add-on prescription drug coverage for anyone enrolled in original Medicare.

If you are interested in enrolling in Part D coverage, you’ll want to make sure to do so as soon as possible. If you don’t enroll in either Part C, Part D, or equivalent drug coverage within 63 days of your initial enrollment, you’ll face a permanent penalty.

If you’ve enrolled in a Part C plan, you won’t need Medicare Part D.

Medigap

Medigap is another add-on option for anyone enrolled in original Medicare. Medigap is designed to help cover some costs associated with Medicare, such as premiums, deductibles, and copays.

If you’ve enrolled in a Part C plan, you cannot enroll in Medigap coverage.

Important Medicare Deadlines

It’s extremely important not to miss any Medicare deadlines, as this can cause you to face late penalties and gaps in your coverage. Here are the Medicare deadlines to pay close attention to:

  • Original enrollment. You can enroll in Medicare Part B (and Part A) 3 months before, the month of, and 3 months after your 65th birthday.
  • Medigap enrollment. You can enroll in a supplemental Medigap policy for up to 6 months after you turn 65.
  • Late enrollment. You can enroll in a Medicare plan or Medicare Advantage plan from January 1–March 31 if you didn’t sign up when you were first eligible.
  • Medicare Part D enrollment. You can enroll in a Part D plan from April 1–June 30 if you didn’t sign up when you were first eligible.
  • Plan change enrollment. You can enroll in, drop out of, or change your part C or Part D plan from October 15–December 7, during the open enrollment period.
  • Special enrollment. Under special circumstances, you may qualify for a special enrollment period of 8 months.

Medicare Part B eligibility begins for most Americans at age 65. Special qualifications, such as disabilities and certain medical conditions, may make you eligible to enroll in Part B early.

If you need more coverage than what Part B offers, additional coverage options include Part C, Part D, and Medigap.
