What 95813 covers

This service covers an extended scalp electroencephalogram recording, with cerebral electrical activity acquired for 61 through 119 minutes. It may be used when a clinician needs a longer diagnostic sample, such as when evaluating suspected seizures, spells of altered awareness, or abnormal mental status. An EEG technologist typically applies the electrodes and acquires the tracing in an outpatient EEG laboratory or hospital; a qualified physician reviews and interprets it.

Select the code from the actual EEG recording duration, not the appointment length or interpretation time. A 41–60-minute recording falls under 95812; other EEG codes may be selected based on the recorded sleep or wake state or clinical circumstance. Documentation should identify the indication, recording duration, technical circumstances, and physician interpretation. CMS recognizes professional and technical components: report modifier 26 for interpretation, modifier TC for equipment and staff, or no component modifier for 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.

95813 billing questions

When does 95813 apply instead of 95812?

Use 95813 for an EEG recording lasting 61–119 minutes. A 41–60-minute recording falls under 95812.

Should the appointment length determine the code?

No. Select the code using the EEG recording duration, rather than the time spent checking in, applying electrodes, or discussing results.

How are the professional and technical portions reported?

Use modifier 26 for the professional interpretation and modifier TC for the technical portion involving equipment and staff. Without either modifier, the claim represents the global service.

What documentation supports 95813?

Document the clinical indication, the EEG recording duration, the technical circumstances, and the physician's interpretation.

How does 95813 differ from an awake-and-asleep EEG?

95813 is selected by recording duration. Codes such as 95819 describe an EEG capturing specified wake and sleep states, so the recorded state and service circumstances guide that choice.

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.
