What 61700 covers
A neurosurgeon typically performs this open operation in a hospital operating room, exposing an intracranial aneurysm through a craniotomy and treating it directly, commonly with a clip. The service is for a simple aneurysm within the brain’s circulation; the operative report should identify the aneurysm, its location, the surgical approach, and the work performed.
Select this code rather than the complex aneurysm-repair code when the documented operation meets the simple level in this code family. Report the operation, not a diagnosis alone. Medicare assigns a 90-day global period, including the day-before preoperative visit and related postoperative care during that period. When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% multiple-procedure reduction. Modifier 50 is inappropriate. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61700 billing questions
How do I choose this code instead of the complex aneurysm-repair code?
Use this code for a simple intracranial aneurysm operation and the complex sibling code when the operative report supports the complex level. Document the aneurysm, approach, and operative work rather than relying on the diagnosis alone.
Does the 90-day global period include related postoperative care?
Yes. The global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can modifier 50 be used for aneurysms on both sides?
No. The CMS bilateral adjustment does not apply to this code, and modifier 50 is inappropriate.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How are other procedures in the same session paid?
The highest-valued procedure is paid in full, and other procedures are subject to the standard multiple-procedure reduction.
