Neurosurgery
About 61692: Intracranial carotid aneurysm surgery
Report 61692 for intracranial surgical treatment of a noncomplex aneurysm in the carotid circulation, such as microsurgical clipping through an intracranial approach.
A neurosurgeon reports this service for operative treatment of an intracranial aneurysm in the carotid circulation using an intracranial approach. A typical example is microsurgical clipping of an anterior circulation aneurysm during a craniotomy. The carotid circulation includes the internal carotid artery and its branches; aneurysms in the vertebrobasilar circulation belong to a different code. Endovascular treatment, such as catheter-based embolization, is a different service.
Select this code when the operative documentation supports the noncomplex carotid-circulation aneurysm service; the complex carotid counterpart is 61698. The note should identify the aneurysm, its vascular territory, the intracranial approach, and the work performed. This major surgery has 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 other procedures are subject to the standard 50% reduction. Assistant-at-surgery payment may be available; co-surgeons require supporting documentation, and team surgery is not permitted.

61692 billing questions
How do I distinguish 61692 from 61698?
Both cover intracranial surgery for an aneurysm in the carotid circulation. Use 61698 when the operative service meets the criteria for a complex aneurysm; use 61692 for the noncomplex service.
When is 61690 reported instead?
61690 is for an intracranial aneurysm in the vertebrobasilar circulation. Confirm the aneurysm's vascular territory in the operative report rather than choosing by approach alone.
Does endovascular coiling support 61692?
No. 61692 describes intracranial surgical treatment; catheter-based CNS embolization is represented by 61624 when that service is performed.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
Can an assistant or co-surgeon be reported?
Assistant-at-surgery payment may be made. Co-surgeons are paid only when supporting documentation is submitted; team surgery is not permitted.
How does the multiple-procedure reduction affect another same-session service?
When multiple procedures are performed in the same session, the highest-valued procedure is paid in full and the others are subject to the standard 50% reduction.
