Which of the following is a Medicare eligibility criterion?

• A. Age 65
• B. 12 months of disability benefits
• C. Enrollment begins at age 70
• D. Only those with End Stage Renal Disease qualify

Answer: (A)

Medicare eligibility is tied to age or qualifying health situations, with 65 being the standard eligibility age. Reaching age 65 makes most people eligible for Medicare, and many are enrolled automatically if they’re already receiving Social Security benefits. While younger individuals can qualify through disability or certain conditions, the common and most straightforward path is turning 65.

The other statements don’t fit because enrollment at 70 is incorrect—the usual eligibility threshold for age-based entry is 65. Eligibility through disability typically requires receiving Social Security Disability Insurance for a period (commonly 24 months, with some conditions like ALS providing earlier access), not just a fixed 12-month period. And End-Stage Renal Disease can qualify Medicare regardless of age, but that’s just one of several paths, not the only one.
