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).
