Neurophysiology
About 95928: Upper-limb central motor evoked potential study
Reports central motor pathway testing that records evoked responses from upper-limb muscles, including during procedures that place motor pathways at risk.
This study evaluates motor pathway conduction from the brain to upper-limb muscles by stimulating the motor system and recording the resulting responses. It is commonly used during procedures such as cervical spine surgery when the team needs to monitor motor pathway function. A neurophysiology professional interprets the responses, while trained technical staff may perform the acquisition in an operating room or diagnostic setting.
Select 95928 for upper-limb motor evoked potential testing; use the code for the bilateral service rather than adding modifier 50 to increase payment. Documentation should identify the tested limbs, stimulation and recording performed, results, and the interpretation. Medicare recognizes professional and technical components: modifier 26 reports interpretation, modifier TC reports equipment and staff, and no component modifier represents the global service. The components are separately priced.
CMS billing rules for 95928
- 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.

95928 billing questions
When should 95928 be selected instead of 95929?
Use 95928 for central motor evoked potential testing of the upper limbs. Code 95929 is the lower-limb counterpart.
Does 95928 include testing on both sides?
Yes. CMS prices the code as bilateral, and modifier 50 does not increase payment.
How should the professional and technical work be billed?
Use modifier 26 for the professional interpretation or TC for the technical service. Without either modifier, the claim represents the global service.
Can 95928 be reported with somatosensory evoked potential testing?
The motor study evaluates motor pathway responses, while somatosensory testing evaluates sensory pathways. Report somatosensory testing only when that distinct study was also performed and documented.
What documentation supports 95928?
Document the upper-limb testing performed, the responses obtained, and the interpretation. For a component claim, the record should support the professional interpretation or the technical work reported.
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.
