CPT code 20912 represents cartilage grafting: the surgical harvest and transplantation of cartilage to repair or reconstruct larger defects in cartilage or bone structures. This procedure is clinically important for nasal reconstruction (including primary and revision rhinoplasty), temporomandibular joint repair, and laryngeal reconstruction after hemilaryngectomy. Nationally, the code is relevant for surgical specialties in otolaryngology, facial plastic surgery, and maxillofacial procedures where structural grafting is required.

Key payers addressed in this overview include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise explanation of the clinical context and typical service settings, along with what to expect in benchmarking and policy-focused sections: coverage patterns, common billing modifiers, and coding relationships. The publication also outlines clinical considerations tied to donor-site selection and reconstructive goals. Data not available in the input is noted where applicable.

This summary equips clinicians, billing professionals, and policy analysts with a clear understanding of what CPT code 20912 denotes, why it matters across payer markets, and the topics covered in the full publication, including payment benchmarks, recent policy updates, and practical coding context for reconstructive cartilage grafting.
