Summary & Overview
CPT 20912: Cartilage Grafting for Reconstructive Procedures
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.
Billing Code Overview
CPT code 20912 describes cartilage grafting, a surgical procedure in which cartilage is harvested from a donor site to fill a larger defect in cartilage or bone structures. The procedure is used to reconstruct or repair areas such as the nasal framework (including rhinoplasty and revision rhinoplasty), the temporomandibular joint, and portions of the larynx following hemilaryngectomy, with attention to preserving cosmetic and functional outcomes.
-
Service type: Surgical cartilage graft harvest and grafting for reconstructive purposes
-
Typical site of service: Operating room or ambulatory surgical center, with donor sites commonly including the nasal septum and other cartilage-bearing regions
Clinical & Coding Specifications
Clinical Context
A 38-year-old patient with a history of nasal trauma presents with a symptomatic external nasal deformity and internal septal collapse causing airway obstruction and aesthetic concern. The ENT surgeon plans a revision rhinoplasty with cartilage grafting harvested from the nasal septum to reconstruct a larger nasal dorsal and tip defect and to restore nasal valve support. Preoperative evaluation includes nasal endoscopy, facial photographic documentation, informed consent discussing donor-site risks (septal perforation, cosmetic deformity), and outpatient same-day surgery scheduling. Intraoperatively, after septal mucoperichondrial elevation and cartilage harvest, the surgeon sculpts and places cartilage grafts to rebuild the nasal framework; hemostasis is achieved and donor-site mucosa is repaired to minimize functional impact. Postoperative follow-up occurs in clinic at 1 week and 6 weeks to monitor graft take, donor-site healing, and nasal airway function.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when work, time, or complexity substantially exceeds the typical for 20912 due to extensive revision or scarring. |
23 | Unusual anesthesia | Use when a procedure normally done with local anesthesia requires general anesthesia for medical reasons. |
26 | Professional component | Use when reporting only the professional (physician) interpretation component if applicable (rare for surgical grafting). |
50 | Bilateral procedure | Use when identical cartilage grafting procedures are performed bilaterally and payer requires bilateral reporting. |
51 | Multiple procedures | Use when 20912 is one of several procedures performed during the same operative session and payer requires modifier for multiple procedures. |
52 | Reduced services | Use when the procedure is partially reduced or not completed as planned. |
53 | Discontinued procedure | Use when the procedure is started but discontinued due to extenuating circumstances. |
59 | Distinct procedural service | Use to indicate a separate, distinct procedure when 20912 is performed in addition to other non-overlapping services. |
62 | Two surgeons | Use when two surgeons work together as primary surgeons performing distinct operative work on the same anatomic site. |
76 | Repeat procedure by same physician | Use when 20912 is repeated later by the same physician during the postoperative period (note: 76 is not in provided list; therefore Data not available in the input.) |
