Question: Which codes should I use for SSEP? Answer: You should choose from three codes for SSEP, or short-latency somatosensory evoked potentials, depending on location: Regardless of the number of skin sites (dermatomes) the neurologist tests during sensory EPs, you may report only a single unit of 95925-95927, as appropriate to the body area the neurologist studies.

Although the descriptors for 95925-92927 do not specify a minimum number of testing sites, these codes do indicate a bilateral procedure. Therefore, if the neurologist studies dermatomes on one side of the body only, you must append modifier -52 (Reduced services) to the appropriate sensory EP study code, according to CPT Assistant, April 2002.
