Question: Medicare has started denying our claims with five units of 92547, stating that we can only bill one unit. What is the reason for this change?

Answer: The denial might be because of whatever other codes you’re also reporting on the claim. CPT® guidelines state that you can only bill add-on code +92547 (Use of vertical electrodes [List separately in addition to code for primary procedure]) with codes 92540-92546 for vestibular, nystagmus, and oscillating tracking tests. If you include +92547 with any other CPT® code, the payer will deny your claim.
