What 95929 covers
This study evaluates motor signals traveling from the brain toward the legs. Transcranial stimulation is used to evoke responses recorded from lower-limb muscles, helping assess central motor pathway function in patients with suspected brain or spinal cord disease. Neurologists and clinical neurophysiologists typically perform or interpret the study in a neurodiagnostic laboratory or hospital setting.
Report 95929 when the central motor evoked potential study evaluates the lower limbs; it is distinct from peripheral nerve conduction testing and sensory evoked potential testing. Documentation should identify the clinical question, stimulation and recording sites, responses obtained, and interpretation. CMS recognizes professional and technical components: modifier 26 identifies interpretation, modifier TC identifies equipment and staff, and no component modifier represents the global service. The code is priced bilaterally, so modifier 50 does not increase payment.

How to choose
- 95928Motor evoked potentialsUpper limbs
- 95928 addresses central motor responses in the upper limbs; 95929 addresses the lower limbs.
- 95939Motor evoked potentialsUpper and lower limbs
- 95939 covers central motor evoked testing of both upper and lower limbs, whereas 95929 is the lower-limb service.
- 95938Sensory evoked potentialsUpper and lower limbs
- 95938 evaluates somatosensory pathways in upper and lower limbs. Choose 95929 for central motor pathway testing of the lower limbs.
- 95940Intraoperative monitoringOne-on-one, in operating room
- 95940 describes intraoperative neurophysiology monitoring time. It is not the diagnostic central motor evoked study represented by 95929.
95929 billing questions
When should 95929 be selected instead of 95928?
Use 95929 for central motor evoked testing of the lower limbs. Code 95928 identifies the corresponding upper-limb study.
Can modifier 50 be used when both legs are tested?
The code is already priced as bilateral. Modifier 50 does not increase payment.
How do modifiers 26 and TC apply?
Modifier 26 identifies the professional interpretation, while modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports reporting 95929?
Document the clinical indication, that the study evaluates central motor pathways to the lower limbs, the stimulation and recording sites, responses, and interpretation.
Is 95929 the same as intraoperative motor pathway monitoring?
No. Code 95929 represents a central motor evoked potential diagnostic study; intraoperative neurophysiology monitoring is a different service.
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.
