Breast prostheses
Medicare Part A (Hospital Insurance) covers surgically implanted breast prostheses after a mastectomy if the surgery takes place in an inpatient setting. Medicare Part B (Medical Insurance) covers the surgery if it takes place in an outpatient setting. Part B also covers some external breast prostheses (including a post-surgical bra) after a mastectomy.
Your costs in Original Medicare
You pay 20% of the Medicare-approved amount for the doctor's services and the external breast prostheses. The Part B deductible applies.
