CPT 00126 | Anesthesia For Tympanotomy Procedures On External, Middle & Inner Ear

CPT code 00126 can be reported when an anesthesia provider performs an anesthesia service on a patient during a tympanotomy procedure on the middle, external or inner ear.


The official description of the 00126 CPT code is: “Anesthesia for procedures on external, middle, and inner ear including biopsy; tympanotomy.”

The American Society of Anesthesiologists (ASA) assigned four base units to CPT 00126.


An anesthesia provider performs a pre-operative evaluation of the patient. Then, the anesthesia provider induces the patient and monitors the patient during a procedure on the external, middle, and inner ear, including biopsy and tympanotomy, that a different provider performs.

The anesthesia provider notes any types and amounts of medications administered, all forms of monitoring used, patient responses, and the start and stop times of anesthesia care.

Following the tympanotomy procedure on the middle, external or inner ear, the anesthesia provider oversees the patient’s transfer to post-anesthesia care.
