About 61697: Complex carotid circulation aneurysm repair
Open intracranial surgery to repair a complex aneurysm in the carotid circulation, reported when the documented anatomy and operative approach meet this level.
This code describes open intracranial surgery for a complex aneurysm in the carotid circulation. A neurosurgeon typically performs the operation in a hospital operating room, using an intracranial approach to treat the aneurysm. The operative report should establish the aneurysm’s location within the carotid circulation, its complexity, and the work performed to repair it.
Select this code based on the documented circulation and complexity; do not choose it solely from aneurysm size. The 90-day global period includes the day-before preoperative visit and related postoperative care for 90 days. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and applies the standard reduction to the others. Assistant-at-surgery services may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted. Modifier 50 is inappropriate for this code.

61697 billing questions
How does this code differ from 61698?
Both describe complex intracranial aneurysm surgery, but 61697 is for the carotid circulation. Code 61698 is for the vertebrobasilar circulation.
Is 61624 interchangeable with this code?
No. Code 61624 describes an endovascular approach to permanent occlusion or embolization in the central nervous system. This code describes open intracranial surgery.
Can modifier 50 be used?
No. The CMS bilateral adjustment does not apply, and modifier 50 is inappropriate for this code.
What documentation supports reporting 61697?
The operative report should identify the aneurysm’s carotid-circulation location, explain the basis for its complexity, and describe the intracranial surgical repair performed.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery services may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
How does the 90-day global period affect billing?
The day-before preoperative visit and related postoperative care for 90 days are included in the major-surgery global period.
