About 95937: Neuromuscular junction stimulation study
Reports stimulation testing of a nerve to evaluate neuromuscular transmission, often during a diagnostic workup for suspected myasthenia gravis or Lambert-Eaton syndrome.
This test evaluates how reliably a nerve signal activates muscle. A neurologist or trained neurodiagnostic staff member may perform repetitive nerve stimulation or another neuromuscular transmission method, with physician interpretation. It is commonly part of an outpatient or hospital evaluation for suspected myasthenia gravis, Lambert-Eaton syndrome, or another disorder affecting transmission between nerve and muscle. Repetitive stimulation may assess changes in the muscle response across repeated stimuli; testing protocols can also examine responses after exercise or facilitation.
Report the service for each nerve tested, using one method for that nerve. Documentation should identify the nerve and method, describe the recorded responses and relevant stimulation conditions, and support the interpretation. CMS recognizes separate professional and technical components: report modifier 26 for the interpretation or modifier TC for the equipment and staff; without either modifier, the claim represents the global service. The professional and technical modifiers are separately priced in the physician fee schedule.

- 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.

How this local rate is calculated
Each RVU component is multiplied by its own geographic practice cost index (GPCI). The three adjusted components are added, then multiplied by the conversion factor. These are the inputs used for 95937 in Colorado.

95937 billing questions
How is this different from a nerve conduction study?
This code evaluates neuromuscular transmission using a stimulation method such as repetitive nerve stimulation. Nerve conduction study codes are selected by the number of qualifying nerve conduction studies performed.
Can this be reported with nerve conduction studies or needle EMG?
They may be reported together when each service is performed and documented as a distinct part of the diagnostic evaluation. The record should support the testing performed under each code.
When should modifier 26 or TC be used?
Use modifier 26 for the physician's interpretation and modifier TC for the technical service, including equipment and staff. Without either modifier, the code represents the global service.
How are units determined?
Report one unit for each nerve tested with one method. The documentation should identify each nerve and the method used.
What documentation supports the service?
Document the clinical indication, nerve tested, stimulation method and conditions, recorded responses, and interpretation. For repetitive stimulation, include the response pattern across stimuli and any relevant exercise or facilitation protocol.
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.
