Summary & Overview
CPT 00326: Anesthesia for Larynx and Trachea Procedures in Infants
CPT code 00326 designates anesthesia for procedures on the larynx and trachea in infants under one year of age. This narrowly focused pediatric anesthesia code captures the specialized airway management and anesthetic care required for very young patients undergoing laryngeal or tracheal procedures. Nationally, accurate use of this code supports appropriate billing for high-acuity pediatric airway services and helps distinguish infant airway anesthesia from general pediatric or adult airway codes.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise clinical context for the code, clarity on the typical service setting, and connections to related anesthesia and spine procedure codes where relevant. The publication summarizes common payer considerations and coding adjacency, including related anesthesia codes for other spinal and regional procedures and select surgical procedure codes that often coincide with complex airway care.
This resource is intended to inform coding professionals, anesthesia departments, and revenue cycle teams about the clinical scope of 00326, typical billing contexts, and where this code fits within anesthesia service lines and operative settings. Data not available in the input for specific payer policies or reimbursement benchmarks is noted as unavailable; the focus remains on code definition, clinical relevance, and common coding adjacencies.
Billing Code Overview
CPT code 00326 describes anesthesia services provided for any procedure on the larynx and trachea in children younger than one year of age. The service type is pediatric airway anesthesia for laryngeal and tracheal procedures. The typical site of service is an operative setting such as an ambulatory surgery center or inpatient operating room where pediatric airway surgery is performed.
Clinical & Coding Specifications
Clinical Context
A 6-month-old infant presents with progressive stridor, feeding difficulties, and episodes of apnea. Otolaryngology evaluation identifies subglottic stenosis and airway compromise requiring direct laryngoscopy and tracheal procedure for airway assessment and possible dilation. The child is scheduled for operating room surgery under general anesthesia with endotracheal intubation appropriate for age. Preoperative evaluation includes airway assessment, review of prior neonatal history (including prematurity and prior intubations), and weight-based medication dosing. The anesthesiology team obtains informed consent from the parent or guardian and prepares for potential difficult pediatric airway management with pediatric-sized equipment, inhalational induction if IV access is not present, and plans for rapid transition to tracheostomy if unable to maintain airway. Intraoperative monitoring includes continuous ECG, pulse oximetry, capnography, blood pressure, and temperature. Anesthesia services are documented from induction through emergence and immediate postoperative handoff. Postoperative care involves monitoring in the post-anesthesia care unit or pediatric intensive care unit depending on airway status and need for ongoing ventilatory support.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
22 | Increased procedural services | Use when anesthesia services are substantially greater in scope, time, or intensity than usual for the procedure, with supporting documentation of increased work. |
