    CPT 92550: Tympanometry and Acoustic Reflex Threshold Measurement

    Medicare pays $22 on average nationally for this procedure.

    CPT code 92550 is a bundled diagnostic audiology service that combines tympanometry to evaluate middle ear function and acoustic reflex threshold measurement to assess inner ear and neural pathways; the service type is diagnostic audiology testing and the typical site of service is an outpatient audiology clinic or otolaryngology (ENT) clinic.

    For related coverage guidance, see recent payer policy updates: Travoprost Intracameral Implant, Ophthalmology - Pilocarpine 1.25%, Cataract Removal Surgery for Adults.

    Clinical & Coding Specifications

    Clinical Context

    A 7-year-old child is referred by their pediatrician to an audiology clinic for evaluation of decreased hearing and recurrent otitis media. The audiologist performs otoscopy followed by a combined tympanometry and acoustic reflex threshold battery under the global service 92550. Tympanometry assesses middle ear compliance and pressure to detect effusion or eustachian tube dysfunction; acoustic reflex threshold testing evaluates stapedius reflex pathways to assess cochlear and brainstem function and middle ear reflex integrity. The typical workflow: history and ear exam, patient positioning in a sound-treated booth or quiet clinic room, probe placement and automated tympanometric sweep, followed immediately by ipsilateral and contralateral acoustic reflex threshold measurements. Results guide diagnosis (e.g., middle ear effusion vs. sensorineural hearing loss) and next steps such as medical management, referral to otolaryngology, or additional audiologic testing. Typical site of service: outpatient audiology clinic, otolaryngology office, or pediatric clinic with audiology capability. Service type: diagnostic audiologic procedure bundling middle ear (tympanometry) and reflex testing (acoustic reflex thresholds).
