Neurosurgery
About 61750: Brain biopsy through burr hole
A neurosurgeon obtains brain tissue through a burr hole or trephine for diagnosis when the biopsy is performed without CT or MR guidance.
The neurosurgeon creates a small opening in the skull with a burr hole or trephine and takes a sample of brain tissue for diagnosis. This service is typically performed in an operating room, often in a hospital, to investigate an intracranial lesion or other abnormal brain finding. The sample is sent for pathologic examination; the surgeon reports the operative biopsy, not the pathologist’s interpretation.
Select this code when the operative report supports a brain biopsy through a skull opening without the CT or MR guidance associated with the stereotactic biopsy alternative. Document the target, approach, tissue obtained, and any dural opening. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and others are subject to the standard 50% reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment is statutorily restricted; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61750 billing questions
When should 61751 be reported instead?
Use 61751 when the brain biopsy is performed with CT or MR guidance. This code describes the biopsy without that guidance.
Can separate brain biopsy codes be reported for multiple tissue samples?
The code describes the biopsy procedure, not each specimen. Document the target and samples obtained; multiple specimens alone do not establish separate procedures.
Does the 90-day global period include postoperative care?
Yes. It includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for biopsies on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code.
Can an assistant surgeon or co-surgeon be reported?
Assistant-at-surgery payment is statutorily restricted. Co-surgeon payment is allowed only with supporting documentation; team surgery is not permitted.
How does CMS handle this code with other procedures in the same session?
Under the standard multiple procedure reduction, the highest-valued procedure is paid in full and other procedures are subject to a 50% reduction.
