Medicare is a federal health insurance program created for seniors age 65 and older.
Medicare also covers younger individuals with certain disabilities and end-stage renal disease (ESRD), which is a type of permanent kidney failure that requires a kidney transplant or dialysis.
Medicare is designed to cover several aspects of senior healthcare, but not all expenses. Without special additions, Medicare is not designed to cover long-term in-home care or most nursing home care. Medicare typically operates based on a fee-for-service model.
