Blood
Medicare covers blood based on where you get it.
Coverage details
Medicare Part A (Hospital Insurance) covers blood you get as a hospital inpatient. Medicare Part B (Medical Insurance) covers blood you get as a hospital outpatient.
Costs
If your provider gets blood from a blood bank at no charge, you won't have to pay for it or replace it. If the provider has to buy blood for you, you must either pay the provider costs for the first 3 units of blood you get in a calendar year, or you or someone else can donate the blood.
Ask your doctor or healthcare provider how much your test, item, or service will cost.
Your doctor may recommend services that Medicare does not cover or offers too frequently. This could end up in additional costs for you. Make sure to ask your doctor about the reasons for these recommendations and what Medicare will actually cover.
Specific amounts you could owe depend on:
Other insurance you may have
How much your doctor charges
If your doctor accepts assignment

Where you get your test, item, or service
