What 92556 covers

An audiologist typically presents speech stimuli to assess the level at which a patient can detect or repeat speech and how well the patient recognizes it. The testing helps characterize hearing difficulty and is commonly performed in an outpatient audiology clinic or an ear, nose, and throat practice. Unlike a speech-threshold-only test, this service includes speech recognition testing as well as threshold assessment.

Report 92556 for the speech portion when both threshold and recognition testing are performed; document the results and the testing performed. It represents the technical testing service, while interpretation is covered by a separate code. The CMS payment basis treats the service as bilateral, so modifier 50 does not increase payment. When a comprehensive hearing assessment is performed, distinguish this speech testing from the broader combination of pure-tone and speech testing represented by 92557.

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.

92556 billing questions

How does 92556 differ from 92555?

92556 includes speech recognition testing along with speech-threshold assessment. Use 92555 when the service is limited to speech-threshold testing.

Is interpretation included in 92556?

No. CMS classifies 92556 as a technical-component-only code; a separate code covers interpretation.

Should modifier 50 be appended when both ears are tested?

The code is already priced as bilateral. Modifier 50 does not increase its payment.

When should 92557 be used instead?

92557 represents comprehensive audiometry combining pure-tone testing with speech audiometry. Use 92556 for the speech testing when the broader comprehensive service is not performed.

What should the record support?

Document that speech-threshold and speech-recognition testing were performed and record the findings for each test.

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.
