What 92547 covers
This add-on represents the technical use of vertical electrodes to capture vertical eye movements during vestibular testing, such as electronystagmography. Audiologists and other qualified clinicians may perform the recording in an audiology or vestibular laboratory, often as part of an evaluation for dizziness, vertigo, or balance problems. It supplements a vestibular test; it is not the interpretation of the recorded findings.
Report 92547 only with an associated primary vestibular procedure when vertical electrodes were used, and document the recording method and the test performed. It is a technical-component-only code, so a separate code covers interpretation. CMS treats it as an add-on paid within the primary procedure’s global period. Examples of associated tests include spontaneous or positional nystagmus testing, optokinetic or tracking testing, and sinusoidal rotational testing.
