About 61533: Craniotomy for cortical electrode placement
Reports craniotomy-based placement of cortical electrodes, commonly for invasive seizure monitoring when noninvasive testing has not localized an epilepsy focus.
A neurosurgeon opens the skull and raises a bone flap to place electrodes on the cerebral cortex, often using subdural grids or strips to record seizure activity. The electrodes support presurgical evaluation when a patient with drug-resistant epilepsy needs more precise localization of a seizure focus. This is an intracranial monitoring procedure, not the later removal of electrodes or resection of brain tissue.
Report 61533 for cortical electrode placement through a craniotomy; placement through burr holes is reported with 61531. The operative report should support the craniotomy approach and electrode placement. Medicare assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, the highest-valued procedure is paid in full and others at 50%. No bilateral adjustment is made. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61533 billing questions
How is 61533 distinguished from 61531?
61533 describes cortical electrode placement through a craniotomy with a bone flap. Use 61531 when cortical electrodes are placed through burr holes.
Does 61533 include later electrode removal?
No. Electrode removal is a separate procedure, reported with 61535 when performed.
When is 61533 used instead of resecting an epilepsy focus?
Use 61533 when electrodes are placed for invasive monitoring to help localize seizure onset. Resection of an identified epileptogenic focus is a different surgical service.
What documentation supports 61533?
The operative report should describe the craniotomy approach and cortical electrode placement. Include the clinical purpose, such as invasive seizure monitoring, when documented.
How do multiple procedures and surgical assistance affect reporting?
When procedures are performed in the same session, Medicare pays the highest-valued procedure in full and others at 50%. Assistant-at-surgery payment may be available; co-surgeon payment needs supporting documentation.
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.
