Billing and Coding: Vestibular and Audiologic Function Studies

Medicare allows specific vestibular and audiologic CPT codes with settings- and component-based restrictions: certain codes are permitted when beneficiaries are receiving long-term ototoxic medications, professional components may be billed in inpatient/outpatient/rehab/nursing/hearing/specialty clinic settings, and numerous codes are technical-only in office/clinic settings. Frequency limits include monthly reporting for specified ototoxic-monitoring codes and limits of one per session and a maximum of two of specified vestibular services per patient per year; documentation must be legible, signed, support the ICD-10 code(s), and accurately describe the CPT/HCPCS billed.

"CPT codes 92553, 92557, and 92568 are allowable when the beneficiary has current long-term use of ototoxic antibiotics."
