Neurosurgery
About 61151: Burr-hole subdural tap
Reports a neurosurgical burr-hole or trephine approach to tap a subdural collection, rather than evacuating or draining a hematoma.
A neurosurgeon creates a burr hole or uses a trephine to access the subdural space and perform a tap, typically to obtain or remove subdural fluid. The code distinguishes this limited tapping procedure from an operation that evacuates or establishes drainage for a subdural hematoma. It is generally performed in an operating-room setting.
Report 61151 when the operative record supports a subdural tap through a burr hole or trephine; document the target space, approach, and action performed. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate. Medicare does not pay an assistant at surgery for this code, and co-surgeons and team surgery are not permitted.

61151 billing questions
How is 61151 different from 61154?
61151 represents a subdural tap. Choose 61154 when the surgeon evacuates and/or drains a subdural hematoma.
When would 61105 be considered instead?
61105 describes a twist-drill approach for subdural or ventricular puncture. 61151 is for a tap performed through a burr hole or trephine.
Can the burr-hole access be billed separately?
The burr hole or trephine is part of the service described by 61151; do not report a separate access procedure for the same approach.
Should modifier 50 be used for bilateral taps?
No. CMS identifies bilateral adjustment as inappropriate for this code.
What documentation supports 61151?
The operative report should identify the subdural target, burr-hole or trephine approach, and that a tap was performed rather than hematoma evacuation or drainage.
How are other procedures in the same session paid?
Under the standard multiple-procedure reduction, the highest-valued procedure is paid in full and other procedures are paid at 50% when performed in the same session.
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.
