Neurodiagnostic testing

About 95927: Trunk or head somatosensory evoked potential study

Reports a somatosensory evoked potential study assessing central sensory pathway responses to stimulation associated with the trunk or head.

This neurodiagnostic study assesses sensory pathway responses by stimulating peripheral sites associated with the trunk or head and recording the resulting electrical signals from the central nervous system. It may be performed in a neurology or neurophysiology setting by trained technical staff, with a qualified physician interpreting the recordings. The study helps evaluate suspected dysfunction along central sensory pathways; it is distinct from testing focused on upper or lower limb pathways.

Select this code when the documented study covers the trunk or head, rather than the upper or lower limbs. The report should identify the stimulation and recording sites, the responses obtained, and the physician’s interpretation. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no component modifier for the global service.

CMS billing rules for 95927

Professional and technical components
Diagnostic test with a professional component (modifier 26, interpretation) and a technical component (modifier TC, equipment and staff); billing without a modifier is the global service.

95927 billing questions

When should this code be selected instead of 95925 or 95926?

Use 95927 for a study involving the trunk or head. Codes 95925 and 95926 identify studies focused on upper and lower limbs, respectively.

How are the professional and technical services reported?

Modifier 26 identifies the professional interpretation, and modifier TC identifies the technical service using equipment and staff. Report the code without either modifier for the global service.

What should the study documentation identify?

Document the stimulation and recording sites, the responses recorded, and the physician’s interpretation supporting assessment of the central sensory pathway.

How does this differ from code 95938?

Code 95927 is for trunk or head testing. Code 95938 represents a complete somatosensory study involving upper and lower limbs.

Is this a motor evoked potential study?

No. This code concerns sensory pathway responses; central motor evoked potential studies use a different code family.

Where these rates come from

FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
