Medicare eligibility, based on age or disability, impacts coverage options significantly. Those eligible at age 65 or with certain disabilities can access Medicare Part A (hospital insurance) and Part B (medical insurance). Eligibility for Part C (Advantage Plans) and Part D (prescription drug coverage) depends on enrollment in Part A and B. Coverage options vary by plan, affecting costs and benefits.
