92567 is the CPT code for tympanometry. It includes impedance testing, a fast diagnostic method that gauges the eardrum’s reaction to pressure variations. Audiologists and ENT providers use it to detect fluid in the middle ear, eustachian tube dysfunction, and eardrum perforations. Without the right code, your claim gets denied. Furthermore, using it incorrectly, whether through bundling errors or billing it more than once per session, costs your practice real revenue. Knowing 92567 is, therefore, not just a billing formality. It is a core competency for anyone managing audiology reimbursements.
This blog covers everything you need to know about CPT code 92567, from its official description and bundling rules to ICD-10 pairings, related hearing test codes, and the most common denial triggers. Whether you are an audiologist, ENT biller, or practice manager, you will leave with a clear, actionable coding reference.
Understand CPT code 92567
92567 sits under the Audiologic Function Tests category of the AMA’s CPT code set. It describes impedance testing, specifically, the measurement of tympanic membrane compliance and middle ear pressure through controlled air pressure variation. The output is a tympanogram, classified as Type A, B, or C, each pointing to a distinct middle ear condition. CMS governs its coverage under LCD L35007. Furthermore, 92567 is session-based and bilateral by default. Consequently, the CPT code for tympanometry carries strict billing rules that directly affect reimbursement, rules most denials trace back to.
Hearing screening CPT code
- 92551: The following CPT code is used under a pure tone air-only and at a fixed intensity.
- 92567: This is the standard CPT code for Tympanometry. It is used for middle ear function. It is recommended as a part of a pediatric hearing screening battery.
- 92558: Automated OAE screening; measures inner ear hair cell response and is the preferred code for newborn hearing screening programs.
- 92650: Automated ABR screening; used for newborns who cannot complete behavioral screening, reporting broadband stimuli with automated analysis.
Hearing test CPT code
- 92552: Pure tone audiometry, air conduction only; diagnostic threshold test determining the lowest intensity at which a patient can hear at each frequency.
- 92553: Pure tone audiometry, air conduction and bone conduction; incorporates bone conduction test to determine if the hearing loss is conductive, sensorineural, or both.
- 92557: This CPT code for tympanometry refers to comprehensive audiometry; a comprehensive code including both air conduction and bone conduction testing (code 92553) as well as speech recognition (92556).
- 92567: Tympanometry; provides a measurement of middle ear compliance and pressure yielding either a Type A, B, or C tympanogram.
- 92550: Tympanometry including acoustic reflex threshold measures; codes for this test instead of 92567 and 92568 performed on the same day.
- 92587: OAEs (Limited); provides information regarding the existence of a hearing disorder through a limited analysis at 3-6 frequencies.
Hearing aid CPT codes
- 92590: Hearing aid examination and selection, monaural; covers the evaluation and fitting process for a single-ear device.
- 92591: Hearing aid examination and selection, binaural; covers evaluation and fitting for both ears in a single encounter.
- 92592: Hearing aid check, monaural; a follow-up visit to verify performance and make adjustments to a single device.
- 92593: Hearing aid check, binaural; same follow-up service performed for bilateral devices.
- 92557: Comprehensive audiometry; frequently performed before hearing aid fitting to establish the audiometric baseline that drives device selection.
V5011–V5267, HCPCS Level II codes; used to bill for the hearing aid device itself, earmolds, batteries, and related supplies when applicable.
Hearing exam CPT code
- 92557: Comprehensive audiometry threshold evaluation and speech recognition; the most complete single-visit hearing exam code covering air, bone, and speech testing.
- 92553: Pure tone audiometry, air and bone; used when a full speech recognition component is not performed but threshold mapping across both conduction pathways is needed.
- 92567: Tympanometry; routinely included in a hearing exam to assess middle ear status before interpreting audiometric thresholds.
- 92568: Acoustic reflex threshold testing; added to a hearing exam when stapedius muscle reflex evaluation is clinically indicated.
- 92579: This CPT code for tympanometry refers to visual reinforcement audiometry (VRA); the standard hearing exam technique for children aged six months to two years who cannot complete conventional behavioral testing.
- 92651: ABR for hearing status determination; used when behavioral hearing exam results are unreliable, or the patient cannot participate in conventional testing.
What is the reimbursement for CPT code 92567?
The reimbursement for CPT code 92567 tympanometry depends on location and modifier. Nonetheless, the first thing you need to know is how much Medicare reimburses CPT 92567. Rates for 92567 are published nationally on a yearly basis by the CMS. These rates have been decreasing steadily over the last decade, just like most other audiologic procedures’ reimbursement.
Medicare rates for 92567
Per the 2025 ASHA Medicare Fee Schedule, CMS reimburses 92567 at the following national rates:
- Non-facility (office): $15.53
- Facility: $10.35
These are national averages. Your Medicare Administrative Contractor (MAC) locality determines your actual rate. Additionally, CMS permits monthly billing of 92567 for patients actively receiving ototoxic medications, a frequency exception documented under LCD L35007. Outside that exception, once per date of service is the hard limit.
How modifiers affect your reimbursement
- Modifier 26: Codes for just the professional component (interpretation and report), when the technical component (equipment and personnel costs) are coded by another party separately.
- Modifier TC: Codes for the technical component only, when the equipment belongs to your clinic but the interpretation is done by a different provider.
- Modifier 52: Modifies the reimbursement amount for tympanometry on one side only; if not included, payers will assume that tympanometry was performed bilaterally, and thus, they will demand back payments for the overpayment.
- Modifier 59: Differentiates the code 92567 from other services that are reported with E/M or other audiological codes on the same date of service.
Furthermore, when both 92567 and 92568 are performed, neither modifier fixes the bundling issue, the correct action is to replace both codes with 92550. Submitting 92567 and 92568 separately on the same claim remains one of the most consistent sources of hearing exam CPT code denials across commercial and Medicare payers alike.
Conclusion
Familiarity with the proper use of CPT code 92567 is very important for successful billing in audiology offices. Although tympanometry is a very common service performed in audiology practices, mistakes in coding, applying modifiers, or billing may result in denials. It is crucial for audiology practitioners to know when this CPT code should be used, whether there is a need to combine 92567 with other CPTs such as 92550, and which modifiers, such as 26, TC, or 59, might be necessary. In addition, knowledge about changes in reimbursement policies is also useful since the Medicare payment for CPT 92567 continues decreasing.

What is the CPT code for tympanometry testing?
CPT code 92567 is used for tympanometry, also called impedance testing. This code is implemented to measure middle ear function by varying the air pressure in the ear.
What is the difference between 92652 and 92653?
