Summary & Overview
CPT 92563: Auditory Nerve Transmission Timing Assessment
CPT code 92563 represents a diagnostic neuro-audiology procedure that measures the timing between a produced tone and when it is perceived to assess transmission of nerve impulses from the ear. Clinically, this test identifies the presence of a hearing disorder and helps localize whether the problem is cochlear, retrocochlear, or central in origin. Nationally, the code is relevant for audiology, otolaryngology, and neurology practices involved in sensorineural and auditory pathway evaluations.
Key payers discussed include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. Readers will find a concise overview of the clinical purpose of the test, typical sites of service, and the payer landscape covered in the analysis. The publication contextualizes how CPT code 92563 is used in diagnostic workflows, operational considerations for outpatient and specialty settings, and benchmarks relevant to claim processing and coverage policies. Data not available in the input is noted where applicable, and the report focuses on national policy, clinical context, and billing implications rather than state-specific rules.
Billing Code Overview
CPT code 92563 describes an assessment of auditory nerve transmission timing by measuring the latency between a produced tone and the patient's perception. The procedure evaluates problems in the transmission of nerve impulses from the ear and helps determine both the presence of a hearing disorder and the likely origin of that disorder.
Service Type: Diagnostic auditory processing / neuro-audiology test
Typical Site of Service: Outpatient audiology clinic, otolaryngology office, or specialized neurodiagnostic laboratory
Clinical & Coding Specifications
Clinical Context
A typical patient is a 45-year-old adult referred to an audiology or otolaryngology clinic for evaluation of asymmetric hearing loss, sudden sensorineural hearing loss, or auditory pathway dysfunction. The patient presents with unilateral tinnitus and difficulty understanding speech in background noise. After case history and pure-tone/word-recognition testing, the clinician orders an auditory brainstem response test to evaluate neural conduction from the cochlea through the brainstem.
The clinical workflow: referral from primary care or ENT; pretest review of medications and contraindications; patient positioned supine or reclined in a sound-treated room; surface electrodes placed at the scalp and mastoid; calibrated earphones deliver click or tone-burst stimuli; the provider records potentials and computes absolute and interpeak latencies and wave morphology; interpretation distinguishes cochlear vs retrocochlear (e.g., acoustic neuroma) origins and documents findings in the report. Results guide next steps such as MRI, vestibular testing, or management by ENT.
