This is a type of health insurance provided by the federal government for people 65 or older, as well as for some people with disabilities. Medicare is divided into four parts: Parts A, B, C, and D. Part A covers in-patient hospital care. Part B provides financial coverage using premiums, deductibles, and a co-insurance structure for other medical expenses, such as doctor visits. Medicare Advantage plans, or Part C, are insurance plans managed by private, approved companies. Part D provides prescription drug coverage. Learn more at
