Final answer:
True, Medicare Part B covers blood costs after the first three pints the beneficiary receives in a calendar year.
Step-by-step explanation:
The statement that Part B of Medicare does not cover blood except after the first 3 pints is True. Medicare Part B is designed to cover a portion of the costs for medically necessary physician services, outpatient care, preventive services, and other medical services. Under Part B, coverage for blood includes the cost, but only after the beneficiary pays for the first three pints. The Medicare beneficiary is responsible for the cost of the first three pints of blood received in a calendar year unless the hospital offers it for free or someone else donates blood to replace what you use.
