What 95957 covers
This service covers computer-based analysis of electroencephalographic data, including analysis directed at identifying epileptic spikes. It is used in neurologic evaluations, particularly when clinicians assess seizure activity from EEG recordings. A neurologist or other qualified professional interprets the analytic output; the technical work uses the equipment and staff needed to process the recorded data.
Report 95957 for the digital analysis itself, rather than for acquiring an EEG or merely reviewing its tracing visually. Documentation should identify the EEG data analyzed, the analysis performed, and the findings or clinical interpretation. Modifier 26 represents the professional interpretation, while modifier TC represents the technical service involving equipment and staff. Without either modifier, the claim represents the global service.
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.

95957 billing questions
How is 95957 different from a routine EEG code?
Routine EEG codes describe recording the brain's electrical activity. 95957 describes digital analysis of EEG data, such as analysis for epileptic spikes.
Can 95957 be reported with the EEG recording?
The EEG recording and digital analysis describe distinct work and may be reported for the same study when both services were performed and documented.
When should modifier 26 or TC be used?
Use modifier 26 for the professional interpretation and modifier TC for the technical service involving equipment and staff. Without either modifier, the claim represents the global service.
What documentation supports the digital analysis?
Record which EEG data were analyzed, the digital analysis performed, and the resulting findings or interpretation. The record should make clear that the service involved analysis, not just EEG acquisition.
Is 95957 the code for EEG monitoring during surgery?
No. 95957 describes digital EEG analysis; 95955 describes EEG monitoring during surgery.
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.
