Medicare is a type of health insurance that began in 1965 under Lyndon B. Johnson that insures people 65 years old and older, people under 65 with specific disabilities and people with End-Stage Renal Disease. Medicare has four parts: A, hospital insurance, which helps cover inpatient care, hospice, in-home care and skilled-nursing facilities; B, medical insurance, which helps cover medical and preventive-care services; C, Medicare Advantage Plans, a health plan that includes Parts A and B in its coverage; and D, prescription drug coverage, which helps cover drug costs and protects against rising drug costs.
