CPT 92596 Pure-Tone Hearing Test Reimbursement

CPT code 92596 represents the technical component of pure-tone audiometry performed while the patient wears ear protectors (ear plugs or earmuffs) to assess hearing thresholds across tone levels. Nationally, this code identifies non-interpretive, equipment- and technician-based audiometric testing that supports diagnostic and monitoring pathways in otology, occupational health, and hearing conservation programs. The technical component designation distinguishes facility or equipment use from professional interpretation services.

Key payers analyzed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise policy and billing overview for this technical audiometry code, including typical sites of service and common modifiers used with technical components. The publication outlines reimbursement context, documentation expectations for technicians and facilities, and how the technical component interacts with professional reporting when interpretation or diagnostic impressions are reported separately.

This summary provides clinicians, billing professionals, and policy analysts with a national perspective on where CPT code 92596 is applied, what it covers clinically, and what stakeholders should expect when it appears on an outpatient or facility claim. Data not available in the input will be noted where relevant in the full publication.

Billing Code Overview

CPT code 92596 describes a pure-tone hearing test (technical component) performed with the patient wearing ear protectors, such as ear plugs or protective earmuffs. The service involves checking a patient’s ability to hear tones at various levels using one or more methods while the patient’s ears are protected from ambient noise.

Service Type: Audiometric testing — technical component

Typical Site of Service: Outpatient clinic, audiology lab, hearing center, or hospital outpatient department

Clinical Context

A 54-year-old factory worker with chronic occupational noise exposure presents to an audiology clinic for evaluation of hearing. The patient is wearing ear protectors (foam earplugs) on arrival because they were instructed to keep them in place until testing begins. The audiology assistant registers the patient, confirms the reason for testing (suspected noise-induced hearing loss and baseline occupational surveillance), and reviews recent otologic history (ear pain, drainage, or recent cerumen removal). The patient is escorted to the sound-treated booth. With the ear protectors in place, the audiology technician performs the technical component of pure-tone audiometry to check the patient’s ability to hear tones at various levels using air conduction and bone conduction transducers as indicated. Test results are recorded and saved to the audiology system. The interpreting audiologist or otolaryngologist later reviews the recorded thresholds and issues the professional interpretation and report separately. Typical site of service is an outpatient audiology clinic, occupational health clinic, or hospital outpatient department. The service type is the technical component of audiometric testing (instrumentation and technician time) performed in a controlled sound environment with the patient using ear protection as specified.

Related Diagnoses

ICD-10 Code	Description	Clinical Relevance
`H83.3`	Noise effects on inner ear	Direct indication for occupational or noise-exposure audiometry to assess threshold shifts.
`H90.3`	Sensorineural hearing loss, bilateral	Common reason for audiometric testing to quantify hearing loss and monitor progression.
`H91.90`	Unspecified hearing loss, unspecified ear	Used when initial audiometric testing documents hearing loss without a more specific etiology.
`H91.21`	Sudden idiopathic hearing loss, right ear	Audiometry is essential to document severity and guide urgent management.

`92567`	Tympanometry and reflex threshold measures	Performed before or after audiometry to assess middle ear function, which can affect air conduction thresholds.
`92588`	Acoustic reflex testing; threshold	Used to evaluate the acoustic reflex pathway and middle ear-muscle reflexes, complementary to audiometric thresholds.
`92626`	Evaluation of auditory-evoked potentials for evoked response (adult)	Used when further diagnostic electrophysiologic assessment is needed following abnormal audiometry.
