What 92570 covers

An audiologist or other qualified hearing professional uses acoustic immittance testing to assess eardrum and middle-ear mobility and measure acoustic reflex responses. The battery includes tympanometry, reflex threshold testing, and reflex decay testing. It is commonly performed in audiology and otolaryngology settings when evaluating conductive hearing loss, middle-ear fluid or pressure problems, or other abnormal hearing findings.

Report 92570 when the documented service includes the comprehensive immittance battery, rather than only one of its component test types. Retain the test results and clinical rationale showing which measurements were performed. CMS treats this as a service without a separately billable professional component, so modifier 26 does not apply. The code is priced as bilateral; modifier 50 does not increase payment.

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.

92570 billing questions

When should 92570 be selected instead of 92567?

Use 92570 for the comprehensive immittance battery, including tympanometry and acoustic reflex measurements. Use 92567 when the service is tympanometry alone.

How does 92570 differ from 92550?

92570 represents the broader battery, including reflex decay testing. 92550 covers tympanometry with acoustic reflex threshold measurements.

Can the component measurements also be billed separately?

The measurements are included in the comprehensive service represented by 92570. Do not separately report a component test for work already included in the battery.

Should modifier 50 be appended for testing both ears?

No. CMS prices 92570 as bilateral, and modifier 50 does not increase payment.

Can modifier 26 be used for the interpretation?

No. CMS identifies this as a service for which the professional component modifier does not apply.

What documentation supports reporting 92570?

Document the clinical reason for testing and the tympanometry and acoustic reflex measurements performed, with the resulting findings.

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.
