What 95830 covers
CPT 95830 describes a surgical procedure to place electrodes for EEG monitoring, generally in a patient undergoing evaluation of difficult-to-localize seizures. A neurosurgeon typically performs the placement in an operating room, using an approach suited to the planned electrode locations. This is distinct from attaching scalp electrodes for a routine EEG recording; the service involves operative electrode placement for invasive monitoring.
Report the procedure when the surgeon places electrodes for EEG monitoring, rather than for the later recording or interpretation alone. The operative report should support the indication, the placement approach, the anatomical locations and types of electrodes, and the work performed. The EEG recording itself may be represented by a separate EEG service when performed and documented. The CMS facts supplied for this code list no code-specific payment rules.

How the 95830 rate is calculated
Each of 95830’s three RVUs is multiplied by a geographic index (GPCI) for the payment locality, added up, and multiplied by the conversion factor. Drag the indexes or enter a ZIP to see what moves the rate.

Payment rules and modifiers for 95830
95830 has no global surgery period, no multiple-procedure, bilateral or assistant-at-surgery adjustment, and no professional/technical split. What changes the payment is where the service happens: the place of service on the claim decides whether Medicare pays the office or the facility rate.

How to choose
- 61760Depth electrodes
- Use 61760 for stereotactic implantation of depth electrodes for long-term seizure monitoring. 95830 describes EEG electrode insertion without that stereotactic service specified.
- 95829Surgical ECoG
- 95829 reports electrocorticography performed during surgery; 95830 reports placement of electrodes for EEG monitoring.
- 95812EEG monitoring
- 95812 reports a routine EEG recording lasting 41–60 minutes. It does not describe operative placement of electrodes.
95830 billing questions
Is 95830 for routine scalp EEG electrode setup?
No. It describes surgical electrode placement for invasive EEG monitoring, not routine attachment of scalp electrodes for a standard EEG recording.
How is 95830 different from stereotactic depth-electrode placement?
95830 reports electrode insertion for EEG monitoring. When the surgeon performs stereotactic implantation of depth electrodes for long-term seizure monitoring, compare the service with 61760.
Can an EEG recording code also be reported?
The placement and the EEG recording are distinct services. A recording code may be appropriate when a separate EEG study is performed and documented; the operative placement alone does not establish that service.
What documentation supports 95830?
The operative report should identify the clinical indication, electrode types and locations, placement approach, and the surgical work performed.
Is 95830 the same as intraoperative electrocorticography?
No. 95830 concerns electrode placement; 95829 describes an electrocorticogram performed 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.
