Prior Authorization
No Prior Auth Required
Code is covered without prior authorization (high confidence)
Documentation Required
- Medical records for patients receiving a once‑yearly implant must document ongoing follow‑up visits at least every 3 to 4 months and must be provided upon request; lack of requested documentation will result in denial as not medically necessary.
- Physician documentation supporting reasonable expectation of survival >12 months is required for coverage of once‑yearly implants for prostate cancer.
- Billing frequency should match the drug formulation administered (e.g., bill Vantas 50 mg implant once per 12 months, Eligard 22.5 mg billed per its 3‑month formulation); medical record must support billed frequency when requested.
- Medical records must document that the ultrasound was limited to retroperitoneal structures when billing CPT 76770/76775/76776, including images/findings demonstrating limitation to the retroperitoneum.
Key Coverage Criteria
- GnRH/LHRH analogs (leuprolide, goserelin, triptorelin, histrelin, leuprolide mesylate/Camcevi) are covered for FDA‑approved indications and for recognized off‑label uses that meet the criteria of LCD L33394.
- Leuprolide acetate and histrelin implants administered every 12 months are covered for treatment of prostate cancer when the treating physician reasonably expects the patient to survive at least 12 months.
- GnRH analogs are covered when administered at frequencies consistent with the specific product's labeled duration of action (e.g., monthly, every 3, 4, 6, or 12 months).
- Retroperitoneal ultrasound (CPT 76770, 76775, 76776) is covered when the exam is limited solely to retroperitoneal structures.
- A full (complete) or limited abdominal ultrasound (CPT 76700, 76705, 76706) is covered when the exam includes organs or structures outside the retroperitoneum or when primary findings involve non-retroperitoneal structures (e.g., gallbladder, liver, spleen, common bile duct).
