Neurosurgery
About 61682: Complex intracranial aneurysm surgery
Reports complex open intracranial surgery to treat an aneurysm, when the operative service meets the CPT complexity category rather than the simple level.
This code represents open surgery through an intracranial approach to treat a complex aneurysm of a cerebral vessel. A neurosurgeon typically performs the operation in a hospital operating room. Surgical treatment may include aneurysm clipping; the operative report should identify the aneurysm, its location, the approach, and the work that supports the complex category. Aneurysm size alone should not be used to infer complexity.
Choose this code rather than 61680 when the documented operation meets the complex category; use the territory-specific complex aneurysm codes when those descriptions fit. CMS assigns a 90-day global period, including the day-before preoperative visit and related postoperative care. When multiple procedures are performed in one session, the highest-valued procedure is paid in full and other procedures are subject to the standard 50% reduction. Modifier 50 is inappropriate for this service. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is not permitted.

61682 billing questions
How does this differ from 61680?
61680 is the simple intracranial aneurysm surgery level. Report 61682 when the operative service meets the complex category, as supported by the operative documentation.
What documentation supports the complex category?
The operative report should identify the aneurysm and its location, describe the intracranial approach and surgical work, and explain the features supporting the complex classification.
Can modifier 50 be used for aneurysms on both sides?
No. CMS identifies bilateral adjustment as inappropriate for this code because the descriptor or anatomy does not support modifier 50.
May an assistant or co-surgeon be reported?
An assistant at surgery may be paid. Co-surgeon payment requires supporting documentation; team surgery is not permitted.
What postoperative care is included?
The 90-day global period includes the day-before preoperative visit and 90 days of related postoperative care.
How are other procedures in the same session paid?
CMS pays the highest-valued procedure in full and applies the standard multiple procedure reduction to the other procedures in that session.
Where these rates come from
FeeBase calculates base physician payments from CMS work, practice-expense, and malpractice RVUs, adjusted by each locality’s geographic indices and the applicable conversion factor. Unavailable or separately priced services are labeled rather than assigned a made-up amount.
