Summary & Overview
CPT 21215: Bone Graft to Mandible for Mandibular Reconstruction
CPT code 21215 identifies surgical application of bone graft material to the mandible for repair of deformity from fracture, injury, tumor resection, or congenital defects. Nationally, this code captures reconstructive maxillofacial work that restores both form and function of the lower jaw, and it is relevant to oral and maxillofacial surgeons, otolaryngologists, and reconstructive plastic surgeons. Payers commonly involved in coverage and payment decisions for this service include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare.
Readers will find a concise clinical and billing overview of the procedure, typical sites of service (operating room in inpatient or outpatient surgical settings), and the clinical contexts in which the code is used. The publication also presents payer coverage patterns, reimbursement benchmarks, and recent policy updates that affect prior authorization and medical necessity determinations. Clinical context sections explain indications—such as mandibular fracture repair, reconstruction after tumor resection, and congenital mandibular hypoplasia—to help clarify appropriate use. The goal is to provide a clear, national-level reference for coding, billing teams, and clinicians involved in mandibular reconstruction services.

Billing Code Overview
CPT code 21215 describes the surgical application of bone graft material to the mandible (lower jaw) to repair deformity of the mandible caused by fracture, injury, tumor resection, or congenital defect, and to restore functional ability and cosmetic appearance. This procedure typically involves placement of autograft, allograft, or synthetic bone substitute to augment or reconstruct mandibular bone.

Service type: Surgical bone grafting for mandibular reconstruction
-
Typical site of service: Outpatient surgical center or inpatient hospital operating room depending on patient complexity and concurrent procedures
Clinical & Coding Specifications
Clinical Context
A 46-year-old male presents with a comminuted left mandibular body fracture after a motor vehicle collision resulting in bone loss and contour deformity. The patient has malocclusion and persistent pain despite initial stabilization. Preoperative CT demonstrates a segmental defect of the mandible requiring reconstruction and augmentation. The surgical team plans open reduction and internal fixation (ORIF) of the mandible with placement of bone graft material to restore mandibular continuity, facial contour, and occlusal function. The procedure is performed in an ambulatory surgical center or hospital operating room under general anesthesia with endotracheal intubation. The workflow includes preoperative imaging and planning, informed consent, general anesthesia, intraoral and/or extraoral exposure of the mandible, debridement of fracture edges, application of autograft or allograft bone material to the defect (CPT 21215), fixation with plates and screws as needed, hemostasis, layered closure, and postoperative recovery with follow-up for healing, occlusion assessment, and possible adjunctive dental rehabilitation or secondary contouring.
