Updates to the Medicare Physician Fee Schedule for 2018

Some questions have come up regarding the billing of sinusoidal vertical axis rotational chair testing, 92546. In the November/December 2017 Audiology Today article, “Billing and Coding the Vestibular Evaluation,” it was recommended billing one unit per plane of testing. By definition, vertical axis rotation is evaluation of the horizontal plane only. Billing CPT code 92546 only applies to horizontal plane testing and the audiologist should not use this code to bill for additional axes.

It is important to check with your third-party payers on billing multiple units for 92546, as there may be variation in coding guidance based upon the payer. Medicare only allows the billing of one unit of 92546 per encounter. CPT Assistant has also published guidance advising that this code is intended to be billed once per encounter. As with all your billing and coding, make sure you check with your patient's third-party payer prior to providing services.
