Part A: hospital insurance
Part A covers inpatient hospital stays, care in a skilled nursing facility after a hospital stay, hospice care, and some home health care. Most people pay no monthly premium for Part A, because they or a spouse paid Medicare taxes while working.
Part B: medical insurance
Part B covers doctor visits, outpatient care, preventive services like screenings and annual wellness visits, lab tests, and durable medical equipment. Part B carries a monthly premium for most people, and you generally pay 20 percent of the cost of covered services after an annual deductible. Both figures are set by Medicare and change each year — ask us and we will tell you what applies right now.
