CPT code 21195 covers surgical reconstruction of the body of the mandible and its perpendicular portions (rami) to correct facial deformities, often resulting from trauma. This code is used for complex oral and maxillofacial procedures that restore mandibular continuity, alignment, and function. Nationally, procedures coded with 21195 are significant because they involve multidisciplinary care, substantial resource use, and potential implications for surgical quality, postoperative rehabilitation, and payer coverage policy.

Key payers considered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find benchmarks on typical utilization and site-of-service patterns, summaries of payer coverage considerations, and clinical context for when reconstruction of the mandibular body and rami is indicated. The publication also outlines common documentation elements that support medical necessity and coding, and highlights policy updates relevant to surgical reconstruction billing practices.

This material is intended to inform coding professionals, surgical teams, and payer policy analysts about the clinical scope and billing context of CPT code 21195, helping stakeholders align documentation and billing processes with current payer expectations and clinical standards.
