What 92546 covers

This vestibular test uses a rotating chair to deliver smooth, back-and-forth changes in rotational speed while eye movements are recorded. The response helps assess vestibulo-ocular reflex function, including in patients evaluated for persistent dizziness, imbalance, or suspected vestibular hypofunction. Audiologists and otolaryngology or neurotology teams commonly perform it in a vestibular laboratory or audiology setting.

Report 92546 for the sinusoidal rotational test itself, supported by documentation of the clinical indication, test performed, recorded response, and interpretation. It is distinct from eye-movement tests that use visual tracking or positional changes, and from caloric testing that stimulates the vestibular system through ear irrigation. For Medicare, modifier 26 identifies the interpretation, modifier TC identifies the equipment and staff service, and no modifier represents the global service.

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.

92546 billing questions

How is 92546 different from 92545?

92546 evaluates eye responses during chair rotation. 92545 evaluates eye tracking of a moving visual target.

Can 92546 be reported with 92540?

92540 represents a basic vestibular evaluation with specified eye-movement tests. Report 92546 separately when sinusoidal chair rotation is also performed and documented.

When should modifier 26 or TC be used?

Use modifier 26 for the professional interpretation and modifier TC for the technical service, including equipment and staff. Submit without either modifier for the global service.

What documentation supports 92546?

Document the reason for testing, the rotational test performed, the recorded eye-movement response, and the interpretation.

Is rotational testing the same as caloric testing?

No. Rotational testing measures responses during chair movement, while caloric testing stimulates the vestibular system through ear irrigation.
