Neurophysiology testing
About 95938: Upper and lower limb sensory evoked potentials
Reports somatosensory evoked-potential testing of upper and lower limb pathways, often used to assess sensory conduction or monitor neural function during surgery.
This study evaluates sensory pathways by stimulating peripheral nerves in the upper and lower limbs and recording evoked responses along the pathway, including at peripheral, spinal, and cortical sites. Neurologists or other qualified clinicians interpret the responses; trained technical staff may perform the stimulation and recording. The study may be performed in a diagnostic neurophysiology laboratory or during surgery when sensory pathway monitoring is needed.
Select this code when the testing covers both upper and lower limbs, rather than only one limb group or dermatomal stimulation. The report should identify the nerves or sites tested, the recorded responses, and the interpretation. Medicare recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or neither modifier for the global service. The code is priced as bilateral, so modifier 50 does not increase payment.
CMS billing rules for 95938
- 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.
- Bilateral procedures
- The code is already priced as bilateral; modifier 50 does not increase payment.

95938 billing questions
When should 95938 be chosen over 95925 or 95926?
Use 95938 for somatosensory evoked-potential testing that covers both upper and lower limbs. Codes 95925 and 95926 describe testing of upper limbs and lower limbs, respectively.
Does 95938 include bilateral testing?
Yes. CMS prices the code as bilateral; modifier 50 does not increase payment.
Which component modifier should be reported?
Report modifier 26 for the professional interpretation or modifier TC for the technical service. Report the global service without either modifier.
Is 95938 a sensory or motor evoked-potential study?
It is a somatosensory study of sensory pathways. Motor evoked-potential testing is distinct; 95939 covers upper- and lower-limb motor evoked potentials.
What documentation supports reporting 95938?
Document the upper- and lower-limb nerves or sites stimulated, the responses recorded, and the clinician's interpretation of the findings.
