CPT 21050: Condylectomy of Mandible for TMJ Disorders
CPT code 21050 represents a condylectomy — the surgical removal of the mandibular condyles at the temporomandibular joint to relieve pain or restore function when condyles are dislocated or diseased. This code is used in billing for operative management of TMJ-related structural problems and is relevant nationally for hospitals, ambulatory surgical centers, and oral and maxillofacial surgery practices. It matters because surgical TMJ interventions have implications for perioperative care, specialist utilization, and payer coverage policies across commercial and public plans.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the procedure, information on typical sites of service and service type, and an overview of common billing considerations. The publication summarizes available benchmarking and policy-related factors where present, highlights payer coverage patterns and authorization considerations, and identifies areas where further coding or documentation clarity may affect reimbursement. Data not available in the input is noted where applicable.
