Under Original Medicare, the government pays directly for the health care services you receive. You can see any doctor that takes Medicare (and most do) anywhere in the country. Original Medicare is sometimes called traditional Medicare.
Unless you make another choice, you will have Original Medicare. You can also choose to get your Medicare benefits from a Medicare private health plan. Medicare private health plans must offer at least the same benefits as Original Medicare but can do so with different rules, costs and restrictions.
In Original Medicare:
You go directly to the doctor or hospital when you think you need care. You do not need to get permission first.
You pay a coinsurance for each service you receive (fee-for-service).
There are limits on how much doctors and hospitals can charge you.
Original Medicare includes:
Medicare Part A (Hospital Insurance)
Part A covers inpatient hospital stays, care in a skilled nursing facility, hospice care, and some home health care.
Medicare Part B (Medical Insurance)
Part B covers certain doctors' services, outpatient care, medical supplies, and preventive services.
