Summary & Overview
CPT 92577: Binaural Simultaneous Speech Test for Unilateral Hearing Loss
CPT code 92577 is a CPT diagnostic code for a binaural simultaneous speech test used to detect unilateral hearing loss or identify pseudohypacusis (nonorganic hearing loss). This focused audiologic procedure helps distinguish true unilateral sensorineural or conductive deficits from inconsistent or nonphysiologic hearing responses and has implications for accurate diagnosis, appropriate referral, and documentation of auditory function nationwide.
Key payers covered in this analysis include Aetna, Blue Cross Blue Shield, Cigna Health, UnitedHealthcare, and Medicare. The review outlines how CPT code 92577 is used in outpatient audiology and otolaryngology settings and summarizes common billing considerations tied to service location and clinical indication.
Readers will learn the clinical purpose and typical use cases for CPT code 92577, the typical sites of service where this testing occurs, and which national payers commonly reimburse for such diagnostic audiologic services. The publication also provides benchmarking context, common modifiers associated with audiology billing where available, and notes on documentation elements that support medical necessity.

Billing Code Overview
CPT code 92577 describes a specialized audiologic test in which the provider delivers words of the same frequency simultaneously to both ears to determine the presence of unilateral hearing loss or to evaluate for pseudohypacusis (nonorganic hearing loss).
-
Service type: Diagnostic audiologic speech testing to assess lateralization of hearing and detect nonorganic hearing loss
-
Typical site of service: Audiology clinic, otolaryngology clinic, or other outpatient diagnostic testing facility

Clinical & Coding Specifications
Clinical Context
A typical patient is an adult referred to audiology by primary care or ENT for asymmetric hearing complaints, suspected unilateral hearing loss, or inconsistent responses suggesting pseudohypacusis. The visit begins with history (onset, noise exposure, otologic symptoms), otoscopic exam, and screening audiometry. When pure-tone testing suggests greater loss in one ear or results are unreliable, the clinician performs the procedure described by 92577 (delivery of words of the same frequency simultaneously to both ears) to detect unilateral hearing loss or nonorganic hearing loss. Results are documented in the audiology note and used to guide further testing (pure-tone audiometry, speech discrimination tests, tympanometry, otoacoustic emissions, or referral to ENT). Typical sites of service include outpatient audiology clinics, ENT offices, and hospital outpatient departments. The patient encounter generally lasts 15–45 minutes depending on additional diagnostic tests and counseling.
