What 95939 covers
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.
This summary was written with AI assistance from CMS physician fee schedule data and checked against the CMS billing rules shown here. Rates on this page come directly from CMS files.

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 indexes and the conversion factor. Services without a published rate are labeled, never given a made-up amount. Amounts are Medicare allowed amounts before claim adjustments: not a patient’s bill or a commercial rate.
