Summary & Overview
CPT 20910: Cartilage Grafting for Reconstructive Defects
CPT code 20910 covers cartilage grafting procedures in which cartilage (commonly costochondral/rib) is harvested to repair or reconstruct larger defects of cartilage or bone, including facial reconstruction, temporomandibular joint repair, and tracheal reconstruction. This code represents an important reconstructive surgery category that intersects plastic surgery, otolaryngology, oral and maxillofacial surgery, and thoracic procedures, with implications for coverage, operative planning, and resource utilization nationally.
Key payers included in this analysis are Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context for the procedure, payer coverage considerations, and typical settings of care. The publication outlines national benchmarks where available, summarizes common billing and coding considerations tied to operative reconstruction, and highlights areas where policy updates or payer guidance may affect prior authorization and documentation expectations.
The content provides clinicians, coding professionals, and policy analysts with a concise reference for the clinical scope of CPT code 20910, expected sites of service, and the payer landscape driving authorization and reimbursement patterns. Data not available in the input is noted where applicable.
Billing Code Overview
CPT code 20910 describes cartilage grafting, a surgical procedure in which a provider harvests a cartilage graft (often costochondral or rib cartilage) from a donor site to repair or reconstruct larger cartilage or bony defects. Common clinical uses include reconstruction of facial defects (such as nasal framework), repair of the temporomandibular joint, and tracheal reconstruction.
Service type: Surgical cartilage grafting / reconstructive graft procedure
Typical site of service: Operating room or surgical suite, with donor-site harvest typically from the chest (costal cartilage) and recipient-site reconstruction on the face, jaw, or trachea.

Clinical & Coding Specifications
Clinical Context
A 42-year-old patient presents with a symptomatic nasal septal defect and external nasal collapse following prior trauma and septorhinoplasty. The surgeon plans harvest of a costochondral cartilage graft to reconstruct the nasal framework and rebuild the dorsal and tip support. Preoperative evaluation in the ambulatory surgery center includes history and physical, chest wall exam to identify suitable rib cartilage, informed consent discussing donor-site risks (chest wall pain, pneumothorax), and anesthesia assessment. Intraoperatively, the facial team performs recipient-site preparation, sculpts a costal cartilage graft from a right-sided rib through a small chest incision, shapes the graft to restore nasal contour, and secures it to native nasal bones and soft tissue. Postoperative workflow includes chest radiograph if clinically indicated, pain control, wound care for both donor and recipient sites, routine postoperative follow-up to assess graft integration and nasal airway function, and documentation of operative details, graft source, and any intraoperative complications for coding and billing purposes.
