What 95955 covers

This service records and interprets cerebral electrical activity during an operation. A classic setting is carotid endarterectomy, where EEG changes can help identify possible cerebral ischemia during carotid clamping. Scalp electrodes capture the tracing while the patient is under anesthesia; a neurologist or other qualified physician interprets the recording, with technical staff supporting electrode placement and recording in the operating room.

Report 95955 for the intraoperative EEG service, not for motor or sensory evoked-potential monitoring alone. The operative and EEG documentation should identify the procedure, monitoring period, recording and interpretation, and clinically relevant findings. CMS recognizes separately priced professional and technical components: use modifier 26 for interpretation, modifier TC for equipment and staff, or neither modifier when billing the global service. CMS lists no add-on status, global period, or multiple-procedure reduction for this code.

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.

95955 billing questions

When is 95955 appropriate instead of an evoked-potential code?

Use 95955 when the monitored signal is the brain's spontaneous electrical activity recorded by EEG during surgery. Motor- or sensory-evoked responses are distinct tests and should be matched to the applicable evoked-potential code.

What do modifiers 26 and TC represent?

Modifier 26 identifies the professional interpretation; modifier TC identifies the technical service, including equipment and staff. Without either modifier, the claim represents the global service.

What documentation supports reporting 95955?

Document the operation and monitoring period, the EEG recording, the interpreting clinician, and the interpretation or relevant changes in the tracing.

Can 95955 be reported for EEG monitoring with drug administration?

95955 describes EEG during surgery. EEG monitoring associated with administration of drugs is a different service; select a code that reflects that service rather than using 95955 solely because EEG was recorded.

Does the code describe EEG digital analysis?

No. 95955 is for EEG during surgery. Digital analysis is a separate EEG service and should not be substituted for intraoperative EEG monitoring.

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.
