Summary & Overview
CPT 92502: ENT Examination Under General Anesthesia
CPT code 92502 documents an examination of the ears, nose, and throat performed while the patient is under general anesthesia. This code captures diagnostic ENT evaluation when an awake exam is impossible or unsafe, such as in uncooperative pediatric patients, anesthetized adults, or trauma victims who have already received anesthesia. Nationally, accurate use of this code affects clinical documentation, coding compliance, and appropriate facility/service-level reporting for perioperative ENT care.
Key payers relevant to this code include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find context on clinical scenarios that prompt use of the code, common sites of service, and typical service descriptors. The publication includes benchmarking of utilization patterns and reimbursement considerations across major payers, plus notes on documentation elements that support correct coding and billing. Where input data is incomplete, the text flags those gaps rather than adding unsupported details.
This summary equips coding managers, billing staff, and clinical leaders with a focused understanding of the clinical purpose of 92502, the payers commonly involved in coverage, and the types of operational and documentation issues that influence claims processing and compliance at a national level.
Billing Code Overview
CPT code 92502 describes an examination of the ears, nose, and throat performed on a patient who is under general anesthesia. The procedure is used when an awake examination is not possible or safe — for example, in an uncooperative child or an adult, or in a trauma patient who has already received anesthesia.
-
Service type: Diagnostic ENT examination under general anesthesia
-
Typical site of service: Operating room, procedure suite, or other inpatient/outpatient setting where general anesthesia is administered
Clinical & Coding Specifications
Clinical Context
A 4-year-old child with recurrent otitis media and significant behavioral distress presents for diagnostic ear, nose, and throat (ENT) examination while under general anesthesia. The child has failed outpatient cooperative exam attempts and the surgeon plans a comprehensive evaluation of the external auditory canals, tympanic membranes, nasal passages, nasopharynx, and oropharynx while the patient is anesthetized. The clinical workflow: preoperative assessment by anesthesia and ENT, induction of general anesthesia in the operating room, performance of the diagnostic ENT endoscopic and microscope exam by the provider, documentation of findings (eg, chronic effusion, obstructing adenoid tissue, foreign body), immediate intraoperative decision-making if procedures are required (eg, myringotomy with tube placement, foreign body removal, adenoidectomy) which would be reported with separate operative CPT codes, recovery from anesthesia, and postoperative documentation noting that the diagnostic exam was performed under general anesthesia due to patient noncooperation and/or trauma status.
Coding Specifications
| Modifier | Description | When to Use |
|---|---|---|
23 | Unusual Anesthesia | Use when a diagnostic ENT exam is performed under general anesthesia and the anesthesia was provided for reasons unrelated to the procedure (eg, uncooperative child) but the service is not normally performed under general anesthesia. |
