Neurosurgery
About 61570: Intracranial foreign body removal
Reports craniotomy to retrieve a foreign object lodged in the brain, such as a retained projectile fragment after a penetrating cranial injury.
This service covers operative retrieval of a foreign object lodged within the brain through a craniotomy. A neurosurgeon typically performs it in a hospital operating room, often when imaging and the operative findings identify an intracranial object requiring removal, such as a retained projectile fragment after a penetrating injury. The target is the foreign object itself, rather than a brain mass or tissue selected for resection.
Report the service when the operative record supports the object’s intracranial location and its removal through craniotomy. The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, CMS pays the highest-valued procedure in full and applies the standard reduction to the others. The anatomy makes modifier 50 inappropriate. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

61570 billing questions
How is this different from 61571?
Use 61570 when the operation removes a foreign object from the brain through craniotomy. Code 61571 concerns surgery directed at an open or penetrating brain wound; the operative service determines which code describes the work.
What documentation supports 61570?
The operative report should identify the foreign object, its intracranial location, the craniotomy approach, and the retrieval performed. Imaging and the injury history can help establish the clinical context.
Can modifier 50 be used for bilateral removal?
No. CMS identifies modifier 50 as inappropriate for this code because of the descriptor or anatomy.
How should other procedures in the same session be paid?
When multiple procedures are performed in one session, CMS pays the highest-valued procedure in full and applies the standard multiple-procedure reduction to the others.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
