- A physician's order is required for VFT performed by licensed audiologists.
- Documentation must record test-specific details (e.g., number of positions tested for CPT 92542; type and laterality of irrigations for CPT 92537/92538 and any use of modifier 52; justification for CPT 92557's speech recognition component; and electrode use/serial testing for CPT 92547).
- Claims and testing must comply with the Local Coverage Determination L34537 and applicable CFR supervision requirements.
Key Coverage Criteria
- Monothermal irrigation (CPT 92538) is covered when both ears are irrigated with the same temperature (cool or warm).
- Vestibular diagnostic procedures (CPT 92541-92542, 92544-92548) are covered when an appropriate ICD-10-CM diagnosis or clinical suspicion for vestibular dysfunction is documented in the medical record and the test is ordered and performed by an authorized provider.
- Basic audiometry (CPT 92552 or CPT 92553) is covered when ordered and performed in conjunction with vestibular function testing (VFT).
