Medicare Part B covers eligible prostate-specific antigen (PSA) screening and medically necessary diagnostic PSA testing under different rules. Ask whether your order is for routine screening, evaluation of a concern or monitoring an established condition; that distinction affects how the claim is reviewed.
Preventive screening has age and timing rules
Medicare.gov lists a screening PSA blood test once every 12 months for men over 50, beginning the day after their 50th birthday. You pay nothing for the covered screening blood test itself. A separate clinician service can still have a charge, particularly when assignment is not accepted.
| Service | Key distinction |
|---|---|
| Screening PSA blood test | Preventive eligibility and timing apply. |
| Diagnostic PSA blood test | Medical need and diagnostic coverage rules apply. |
| Digital rectal examination | Different cost sharing from the PSA blood test. |
| Office consultation | May be a separate billed service. |
Diagnostic testing is not an unlimited screening benefit
CMS policy 190.31 addresses diagnostic PSA testing for specified clinical circumstances, including relevant symptoms and cancer follow-up. The ordering provider should document the reason and appropriate frequency. A change in medical circumstances is different from simply requesting another routine screening early.
Questions before the blood draw
- What is the documented purpose of this test?
- When was my last Medicare-covered screening?
- Will the laboratory receive the correct order?
- Are there separate consultation or facility charges?
- Does my Medicare Advantage plan require a particular laboratory?
If denied, ask the billing office to check the actual order and claim for errors before following the appeal instructions. Never request an inaccurate diagnosis to obtain coverage. Discuss the benefits and limitations of screening with your clinician; this article does not interpret PSA results.
