Summary & Overview
CPT 00160: Anesthesia for Nose and Accessory Sinus Procedures
CPT code 00160 represents anesthesia services for procedures on the nose and accessory sinuses when a more specific anesthesia code is not available. This code is used to report perioperative anesthesia care tied to intranasal and paranasal sinus surgeries, a clinically important category given the volume of otolaryngology procedures nationally. Accurate use of this code supports proper clinical documentation, billing integrity, and claims adjudication for airway- and sinus-related operations.
Key payers addressed in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, United Healthcare, and Medicare. Readers will find a concise description of the clinical and billing context for the code, common related procedural pairings, typical sites of service, and the range of diagnosis codes that commonly justify use of the code. The publication also outlines common modifiers associated with anesthesia services and situates 00160 among related otolaryngology procedure codes to aid coding clarity.
The content is intended for a national audience of clinicians, coding professionals, and policy analysts who need a clear operational summary of CPT code 00160, its clinical scope, and the payer landscape that most frequently intersects with its use.
Billing Code Overview
CPT code 00160 describes anesthesia services provided for procedures on the nose and accessory sinuses, the hollow chambers in the skull that open into the nasal cavity. These services cover perioperative anesthesia care specific to intranasal and paranasal sinus procedures when no more specific anesthesia code is available.
Service type: Anesthesia for nasal and accessory sinus procedures
Typical site of service: Operating room or ambulatory surgical center
Clinical & Coding Specifications
Clinical Context
A 45-year-old patient presents to an otolaryngology clinic with long-standing nasal obstruction, recurrent sinonasal infections, facial pressure, and anosmia. Clinical exam and nasal endoscopy demonstrate hypertrophy of the inferior turbinates and a deviated nasal septum with polypoid changes. Imaging confirms chronic sinusitis involving the maxillary and ethmoid sinuses. The patient is scheduled for functional endoscopic sinus surgery and septoplasty under general anesthesia. The anesthesiology team documents a regional airway assessment, obtains informed anesthesia consent, establishes standard monitors, induces general anesthesia with endotracheal intubation, and provides intraoperative anesthetic management for nasal and accessory sinus procedures. The anesthesia provider reports services using 00160 when no more specific anesthesia code for sinus/nasal procedures applies. Typical workflow includes pre-anesthesia evaluation, intraoperative airway and hemodynamic management, emergence and immediate postoperative handoff to recovery room staff, and documentation of any intraoperative complications or increased complexity that may warrant a modifier (e.g., prolonged time or unusual anesthesia circumstances).
