What 61690 covers
This code describes open surgery to treat an aneurysm involving an intracranial vessel. A neurosurgeon typically performs the operation in a hospital operating room, using an intracranial approach to reach and treat the affected vessel. The operative report should identify the aneurysm, its location, the approach, and the work performed; those details support choosing this code over another aneurysm or vascular-malformation procedure.
Report the code for the service actually performed, using the applicable billing code criteria to distinguish it from related intracranial aneurysm surgery codes. CMS assigns a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures occur in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard multiple-procedure reduction. An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation, and team surgery is not permitted.

The operative report should identify the aneurysm and vessel location, describe the surgical approach and treatment performed, and provide the details needed to support the applicable code selection.
How does the 90-day global period affect billing?
The day-before preoperative visit and 90 days of related postoperative care are included in the global period.
Can an assistant or co-surgeon be reported?

What happens when another procedure is performed in the same session?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
