Summary & Overview
CPT 31254: Partial Anterior Ethmoidectomy, Endoscopic Sinus Surgery
CPT code 31254 denotes a partial surgical anterior ethmoidectomy involving uncinate process removal (infundibulotomy), opening of the bulla, and partial removal of anterior ethmoid cells. The code captures a focused endoscopic sinus procedure commonly performed by otolaryngologists to restore sinus ventilation and treat refractory or recurrent sinonasal disease. Nationally, accurate coding for this procedure affects surgical utilization metrics, payment determinations, and quality measurement for sinus surgery services.
Key payers in this review include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find an overview of clinical context, typical sites of service, common billing modifiers (listed separately), and the relationships between CPT code selection and procedural documentation. The publication provides benchmarks for service lines and payer coverage patterns where available, clarifies the clinical components represented by the code, and highlights implications for facility and professional billing across hospital operating rooms and ambulatory surgery centers.
This summary is intended to orient clinicians, coders, and policy stakeholders to the procedural definition and national relevance of CPT code 31254, and to signal areas where clinical documentation and coding alignment are important for accurate claims processing and reporting. Data not available in the input is noted where applicable in detailed sections.

Typical site of service: Hospital operating room or ambulatory surgery center
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient with chronic rhinosinusitis refractory to maximal medical therapy presents for endoscopic sinus surgery. Preoperative CT shows obstruction of the anterior ethmoid infundibulum with opacification of the anterior ethmoid cells and enlargement of the bulla ethmoidalis. The otolaryngologist performs an endoscopic partial surgical anterior ethmoidectomy (31254) under general anesthesia in an operating room ambulatory surgery center setting. The procedure includes uncinate process removal (infundibulotomy), opening of the bulla, and partial removal of anterior ethmoid cells to re-establish drainage of the frontal recess and anterior ethmoid system. Typical workflow includes preoperative nasal endoscopy and CT review, general anesthesia with topical decongestant and local infiltration as needed, endoscopic visualization, removal of the uncinate, opening of the bulla, limited anterior ethmoid cell removal, hemostasis, and postoperative packing or debridement instructions. Postoperative follow-up includes in-clinic endoscopic debridement and saline irrigations.
