Medical-necessity criteria Carelon generally applies
Carelon restricts knee arthroscopy per evidence-based criteria. Approved indications: (1) Acute traumatic meniscal tear with documented mechanical symptoms (true locking with inability to fully extend, significant catching/giving way) and failure of PT ≥4 weeks where PT participation is possible; (2) Displaced bucket-handle meniscal tear causing true locking (unable to extend knee to neutral); (3) Symptomatic loose body with mechanical symptoms; (4) Septic arthritis joint washout. NOT covered: knee arthroscopy for OA, degenerative meniscal tears in the absence of true mechanical locking, chondroplasty alone, or "diagnostic" arthroscopy when MRI available

Degenerative knee arthroscopy is not covered by Carelon. Document mechanical symptom precisely — "knee pain with range of motion" is insufficient. "True mechanical locking with inability to fully extend" is the required language for locked knee cases.
