Nearly 63 million Americans are enrolled in Medicare
Medicare is the federal health insurance program created to provide a safety net for senior citizens as well as disabled enrollees who meet specific criteria. The Centers for Medicare and Medicaid Services reports that nearly 62.75 million Americans were enrolled in Medicare as of mid-2020.
All of these people have an opportunity to make various changes to their coverage during the annual fall enrollment period (October 15 through December 7).
Eligibility depends on your age, other variables
For the vast majority of Americans who look forward to receiving Medicare health benefits, eligibility is as uncomplicated as celebrating your 65th birthday. But eligibility isn’t dependent solely on your age.
- Am I eligible for Medicare health coverage?
- At what age am I eligible for Medicare?
- How do I know if I qualify for Medicare?
- You can be enrolled in Medicare and Medicaid at the same time.
- Can recent immigrants to the United States get health coverage if they’re over 65?
When can you enroll in Medicare?
Millions of Americans are automatically enrolled in Medicare Part A and Part B at age 65. Others have an enrollment window during which they can sign up for Medicare when they’re turning 65, and still others gain eligibility for Medicare due to a disability or diagnosis of ALS or end-stage renal disease. It’s important to know Medicare open enrollment dates for initial enrollment and beyond.
