Some people may be eligible for Medicare under 65 if they have certain medical conditions, such as disabilities, Amyotrophic Lateral Sclerosis (ALS) or end-stage renal disease (ESRD), according to the official Medicare website. In all other circumstances, only people over 65 are eligible.
Medicare is a federal health insurance program designed specifically for people over the age of 65. There are four parts to the program: Part A, Part B, Part C and Part D. Part A and B provide basic coverage, providing coverage for hospital and doctors' visits, respectively. Part C and D are private plans that operate within the Medicare system and must be purchased. Part C functions as an alternative to Parts A and B, and Part D offers coverage for prescription drugs, according to CNN Money.
