Summary & Overview
CPT 21355: Closed Reduction of Zygoma (Cheekbone) Fracture via Puncture Incisions
CPT code 21355 denotes closed reduction repair of fractures of the zygoma (cheekbone) performed through puncture incisions. Nationally, this code captures an important category of facial trauma management that affects surgeons, hospitals, and payers due to the acuity of injury, need for procedural expertise, and variable site-of-service utilization. Coverage and payment vary across major payers, influencing where and how these repairs are provided.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of clinical context for cheekbone fracture repair, typical settings where the procedure is performed, and the common payment landscape across commercial and federal payers. The publication summarizes benchmarks for utilization and reimbursement patterns, notes relevant coding considerations, and highlights policy updates that commonly affect authorization and site-of-service decisions. Practical takeaways include typical clinical indications tied to CPT code 21355, how payer policies shape care pathways, and operational considerations for facilities and surgical teams. Data not available in the input is clearly identified where applicable.
Billing Code Overview
CPT code 21355 describes repair of a fracture of the cheekbone (zygoma) area using manipulation performed through puncture incisions. The procedure involves closed reduction techniques to realign zygomatic or malar fractures without large open exposures.
-
Service type: Closed reduction of zygomatic (cheekbone) fracture through puncture incisions
-
Typical site of service: Operating room, ambulatory surgery center, or hospital procedural suite
Clinical & Coding Specifications
Clinical Context
A 28-year-old male presents to the emergency department after an altercation in which he sustained blunt facial trauma. Examination and facial CT demonstrate a noncomminuted zygomaticomaxillary complex (cheekbone) fracture with mild displacement and periorbital swelling but no globe injury. The patient undergoes closed reduction of the zygomaticomaxillary complex using percutaneous manipulation through small puncture incisions with internal fixation avoided; the procedure is performed in an operating room under general anesthesia by a maxillofacial surgeon. Typical workflow includes triage and imaging (facial radiographs/CT), preoperative assessment and informed consent, administration of anesthesia, percutaneous manipulation and reduction through puncture incisions, intraoperative imaging or clinical confirmation of reduction, wound care and dressing, recovery and discharge with postprocedure instructions and follow-up for occlusion, facial symmetry, and sensory assessment.
Coding Specifications
