Table of Contents

Summary: Most people become eligible for Medicare Part B when they turn 65. However, some individuals may be eligible under the age of 65 if they have a disability or certain qualifying illnesses. In this article, we’ll go into detail about the eligibility requirements for Medicare Part B and why it’s important to know when you qualify. Estimated Read Time: 4 min

Who Is Eligible for Medicare Part B?

U.S. citizens who are age 65 or older are eligible for Medicare Part B. Individuals under the age of 65 also qualify for Medicare Part B if they meet certain criteria.

You are eligible for Medicare Part B at age 65 if: You are a U.S. citizen or permanent resident for at least 5 years.

Individuals who are turning 65 will first become eligible to enroll in Medicare Part B (and Part A) three months before their 65th birthday. If your birthday falls on the first day of the month, you will become eligible to enroll in Medicare Part B for the first time four months prior to your birthday.

You qualify for Medicare Part B under age 65 if: You have received disability benefits through Social Security or Railroad Retirement Board for 24 months or have been diagnosed with End-Stage Renal Disease (ESRD) or Lou Gehrig’s disease (ALS).

Individuals who are diagnosed with ALS will become eligible for Medicare Part B (and Part A) as soon as they begin receiving disability benefits. If you qualify for Medicare Part B due to ALS, you will automatically be enrolled.

It is important to understand when you will become eligible for Medicare Part B for a few reasons. First, signing up for Medicare Part B when you first become eligible can help you avoid having a gap in healthcare coverage. Additionally, signing up for Medicare Part B as soon as possible can also help you avoid late enrollment penalties.

Am I Eligible for Medicare Part B if I Have to Pay for Part A?

There are no additional eligibility requirements for Medicare Part B if you are someone who must “buy” Medicare Part A. If you haven’t worked and paid Medicare taxes for 40 or more quarters (10 years), you may need to pay a monthly premium for Medicare Part A; this is referred to as “buying” Part A.

You will still become eligible for Medicare Part B when you turn 65 and may choose to only enroll in Part B coverage at that time. If you choose to buy Medicare Part A, you will need to maintain your Medicare Part B coverage to have Part A coverage.
