Summary & Overview
CPT 92517: Vestibular Evoked Myogenic Potential (VEMP) Testing
CPT code 92517 represents vestibular evoked myogenic potential (VEMP) testing, a diagnostic electrophysiology procedure that records cervical muscle responses to high-level acoustic stimuli to evaluate inner ear and vestibular system function. Nationally, VEMP testing is important for diagnosing vestibular neuritis, superior canal dehiscence, and other balance disorders that impact patient care pathways and utilization of specialized diagnostic services.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The publication outlines coverage and reimbursement context across major national payers and Medicare, presenting clinical context, typical sites of service, and common billing practices associated with the procedure.
Readers will learn the clinical purpose of CPT code 92517, where the test is typically performed, and which payers are commonly involved in coverage decisions. The report summarizes typical charge and utilization benchmarks where available, highlights relevant policy and billing considerations, and provides a concise reference for coding and documentation needs tied to VEMP testing. Data not available in the input will be noted as such in relevant sections.
Billing Code Overview
CPT code 92517 describes vestibular evoked myogenic potential (VEMP) testing, a diagnostic procedure that measures the neck (cervical) muscle response to high-level acoustic stimuli delivered to the ear. The service evaluates how sound triggers reflexive muscle activity when it reaches the inner ear, aiding assessment of ear and vestibular system disorders.
-
Service type: Diagnostic vestibular/otologic electrophysiology testing
-
Typical site of service: Outpatient clinic, hospital outpatient department, or specialized neurotology/otology diagnostic lab

Clinical & Coding Specifications
Clinical Context
A 52-year-old patient is referred to an otology/vestibular clinic for evaluation of recurrent episodic vertigo and unilateral aural fullness. The neurologist and primary care physician note a history of sudden sensorineural hearing loss on the left six months prior and persistent imbalance. The patient undergoes vestibular evoked myogenic potential testing to assess saccular and inferior vestibular nerve function. Electrode leads are placed on the cervical region over the sternocleidomastoid muscles and on the mastoid/vertex as appropriate. Acoustic stimuli (air- or bone-conducted tone bursts or clicks) are presented to each ear while the patient contracts the neck muscles to generate reliable responses. The technologist records responses, and the interpreting clinician (otolaryngologist or neurotologist) reviews waveforms, measures latencies and amplitudes, documents interaural amplitude asymmetry, and issues a formal report with interpretation and recommendations for further vestibular testing or management. Typical workflow includes pretest consent, positioning and instruction, electrode placement, stimulus delivery, signal averaging and repeats for reliability, immediate review for technical adequacy, and final interpretation and reporting in the medical record.
