Final answer:
Medicare Part B generally covers the cost of blood transfusion, up to three pints.
Step-by-step explanation:
Medicare supplement care benefits, also known as Medigap, is designed to help pay for expenses that Medicare Part A and Part B does not cover. This includes copayments, coinsurance, and deductibles. While Medigap plans do not cover blood transfusion costs, Medicare Part B generally covers the cost of the blood itself, up to three pints in most cases.
