What 92550 covers
This service combines tympanometry, which measures middle-ear response to changes in ear-canal pressure, with acoustic reflex threshold testing, which checks the sound level that elicits a middle-ear muscle reflex. Audiologists commonly perform it in an audiology clinic or ENT practice when assessing hearing loss, abnormal middle-ear findings, or suspected eustachian tube or middle-ear dysfunction. Results help characterize middle-ear function alongside other hearing test findings.
Report 92550 when both tympanometry and reflex threshold measurements are performed; use a single-component code when only one of those tests is done. The record should identify the clinical reason for testing and include the findings for the measures performed. CMS prices this code as bilateral, so modifier 50 does not increase payment. The professional component modifier does not apply; do not split the service into professional and technical claims using modifier 26.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

92550 billing questions
When should 92550 be reported instead of 92567?
Report 92550 when tympanometry and acoustic reflex threshold testing are both performed. Use 92567 when the service is tympanometry alone.
Can the reflex threshold test be billed separately with 92550?
92550 combines tympanometry and reflex threshold testing. Do not separately report the reflex measurement for the same work.
Should modifier 50 be appended when both ears are tested?
No. CMS prices 92550 as bilateral, and modifier 50 does not increase payment.
Can modifier 26 be used for the interpretation?
No. The CMS component rule states that the professional component modifier does not apply to this service.
What documentation supports reporting 92550?
Document the reason for testing and findings for both the tympanometry and acoustic reflex threshold measures performed.
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.
