Who is eligible for Medicare?

• A. Individuals aged 55 or older
• B. Individuals aged 65 or older
• C. Individuals with chronic illnesses only
• D. Individuals receiving Social Security only

Answer: (B)

Medicare eligibility is primarily determined by age, and the program is designed to serve individuals who are 65 years old or older. This age threshold is established by the federal government, allowing those who reach this age to enroll in Medicare and access health care services it provides, such as hospital coverage (Part A) and outpatient coverage (Part B).

While there are additional eligibility criteria, such as certain groups under 65 who may qualify due to disabilities or specific medical conditions (like End-Stage Renal Disease), the foundational eligibility criterion centers around age 65. Hence, option B accurately reflects this core aspect of Medicare eligibility.

The other choices do not encompass the broad eligibility criteria of Medicare. Individuals aged 55 or older do not qualify for Medicare, as the minimum age is 65. Chronic illnesses alone do not automatically grant eligibility without meeting age or disability requirements. Lastly, while being a recipient of Social Security may lead to earlier Medicare eligibility in some cases (for those under 65), it is not a sole requirement, as individuals can qualify due to various factors beyond just Social Security receipt.
