CPT code 00326: Airway anesthesia, larynx or trachea, under 1 year2026 Medicare rate & RVUs

Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 00326 covers

This service covers anesthesia for a patient younger than 1 year undergoing a procedure involving the larynx or trachea. An anesthesia practitioner reports the service alongside the surgeon or proceduralist performing the airway procedure in an operating room or other procedural setting.

Choose this code for the infant’s laryngeal or tracheal procedure rather than a general neck procedure. The operative and anesthesia records should identify the patient’s age and the laryngeal or tracheal target and procedure. Medicare payment is based on 7 base units plus time units, multiplied by the anesthesia conversion factor for the locality. Anesthesia time is reported in minutes and converted to 15-minute units to one decimal place; it starts when the practitioner begins preparing the patient for anesthesia and ends when the practitioner is no longer in personal attendance and the patient can safely be placed under postoperative care.
