CPT code 92552: Pure-tone audiometry, air conduction only2026 Medicare rate & RVUs in Missouri
Reports air-conduction hearing threshold testing across frequencies, commonly used to assess suspected hearing loss without bone-conduction or speech testing.
Medicare pays $34.88–$38.49 for 92552 in the office in Missouri, from Rest of Missouri to Metropolitan St. Louis, MO. Which amount applies depends on the service address.
Medicare allowed amount for participating (non-QP) physicians, before deductible, coinsurance and claim adjustments. Not a patient’s bill or a hospital charge.

What 92552 covers
Pure-tone air-conduction audiometry measures hearing thresholds across test frequencies by presenting tones through earphones and recording the softest levels detected. Audiologists commonly perform it in audiology clinics, ENT offices, and hearing centers to assess suspected hearing loss, document asymmetry, or monitor a known hearing condition. The audiogram records the thresholds for each ear; this code represents neither bone-conduction nor speech-recognition testing.
Report 92552 for the air-conduction threshold service rather than a screening test or a broader audiologic battery, and retain the test findings and clinical reason in the record. CMS treats it as technical-component-only; interpretation is represented by a separate code, so this line covers the testing work. The code is priced bilaterally, covering both ears under one code; modifier 50 does not increase payment.

How to choose
- 92551Hearing screeningPure tone, air only
- 92551 is an air-conduction screening test. Choose 92552 when the service measures hearing thresholds across frequencies rather than screening for possible hearing loss.
- 92553AudiometryAir and bone thresholds
- 92553 includes air- and bone-conduction threshold audiometry. Use 92552 when only air-conduction thresholds are tested.
- 92557Comprehensive hearing testAir, bone, and speech testing
- 92557 represents comprehensive threshold evaluation with speech recognition. Use 92552 when the reported testing is limited to air-conduction thresholds.
92552 billing questions
When should 92552 be used instead of 92551?
Use 92552 for threshold audiometry that measures hearing levels across test frequencies. Code 92551 describes pure-tone air-conduction screening, not threshold testing.
How does 92552 differ from 92553?
92552 covers air-conduction thresholds only. Use 92553 when the audiometry includes both air- and bone-conduction thresholds.
Is 92552 reported once for both ears?
The CMS fee schedule prices 92552 as bilateral. Modifier 50 does not increase payment.
Can the interpretation be billed under 92552?
No. CMS identifies 92552 as technical-component-only, with interpretation covered by a separate code.
When is 92557 a better fit than 92552?
Use 92557 when the service is comprehensive audiometry that includes threshold evaluation and speech recognition. 92552 represents air-conduction threshold testing alone.
Can tympanometry be reported with 92552?
92567 may be reported for separately performed tympanometry during the same encounter; it evaluates middle-ear function rather than air-conduction hearing thresholds.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense and malpractice RVUs, adjusted by each locality’s geographic indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
