Summary & Overview
CPT 21210: Facial Bone Graft for Nose, Upper Jaw, and Cheeks
CPT code 21210 covers surgical placement of bone graft material to the face to correct cosmetic deformities of the nose, maxilla (upper jaw), and malar (cheek) bony structures caused by injury or disease. This code is relevant for reconstructive and aesthetic facial surgery and is commonly used in contexts where restoration of contour and structural support is required after trauma, oncologic resection, or congenital defects. Nationally, accurate coding for facial bone grafting affects claims processing, clinical documentation, and coverage determinations for reconstructive facial procedures.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical intent of the code, payer coverage context, common billing modifiers (list provided separately), and typical sites of service. The publication includes benchmarks where available, coding and documentation considerations, and policy updates that influence coverage and prior authorization practices. The content is intended to help coding and billing staff, clinical leaders, and revenue cycle teams understand the clinical scope and administrative considerations associated with CPT code 21210 on a national level.
Billing Code Overview
CPT code 21210 describes the application of bone graft material to the face to correct cosmetic deformities of the bony structures of the nose, upper jaw, and cheeks caused by injury or disease. The procedure addresses contour defects and structural deficiencies of facial bones through placement of graft material to restore form and function.
-
Service type: Surgical facial bone grafting for correction of cosmetic and structural deformities
-

Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents to a facial plastics and reconstructive surgery clinic following an auto-related nasal and midface fracture with resultant contour deformity and persistent collapse of the nasal dorsum and infraorbital rim. After imaging and fracture management, the surgeon plans an outpatient procedure to apply bone graft material to the nasal bones, maxilla, and zygomatic buttress to restore facial symmetry and correct functional/cosmetic deformity. Preoperative workup includes history/physical, facial CT for planning, anesthesia evaluation, consent, and selection of graft source (autograft, allograft, or bone substitute). The procedure is typically performed in an ambulatory surgery center or hospital operating room under general anesthesia. Intraoperative steps include exposure of the affected bony contours, preparation and placement of bone graft material to augment depressed areas, fixation or contouring as needed, hemostasis, and layered closure. Postoperative workflow includes recovery monitoring, analgesia, instructions for wound care, activity restrictions, outpatient follow-up for incision and graft assessment, and imaging if complications are suspected.
