Neurophysiology
About 95939: Upper and lower limb motor evoked-potential study
Reports transcranial motor evoked-potential testing of both upper and lower limbs to assess central motor pathway function in a diagnostic evaluation.
This study uses transcranial stimulation and records muscle responses in the arms and legs to evaluate motor pathways from the brain through the spinal cord. Neurologists and other clinicians trained in clinical neurophysiology may perform or interpret it, with trained technical staff assisting in physician offices and hospital settings. A clinician may order it when evaluating suspected dysfunction affecting central motor pathways, such as spinal cord disease.
Choose this code when the study covers both upper and lower limbs; codes 95928 and 95929 distinguish upper-limb-only and lower-limb-only studies. The report should identify the tested limb regions, recorded responses, and interpretation. CMS recognizes separately priced professional and technical components: report modifier 26 for interpretation alone, TC for equipment and staff, or no component modifier for the complete service. The code is priced as bilateral, so modifier 50 does not increase payment.
CMS billing rules for 95939
- 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.

95939 billing questions
When should I report this instead of 95928 or 95929?
Report this code when the motor evoked-potential study includes both upper and lower limbs. Code 95928 is for upper limbs, and 95929 is for lower limbs.
Should I append modifier 50?
No. CMS prices this code as bilateral, and modifier 50 does not increase payment.
How do I report the professional and technical components?
Use modifier 26 for the professional interpretation and TC for the technical service, including equipment and staff. Bill without a component modifier when reporting the complete service.
What documentation supports reporting this code?
Document that both upper and lower limbs were tested, the recorded motor responses, and the clinician's interpretation of the findings.
Can this be reported with somatosensory evoked-potential testing?
It may be reported with 95938 when both motor and somatosensory pathways are evaluated during the encounter. The record should support each distinct study.
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.
