What 61680 covers
This service covers open neurosurgical treatment of an arteriovenous malformation within the brain. A neurosurgeon typically uses an operative approach to identify and interrupt abnormal vascular connections or remove the malformation. The work is distinct from catheter-based embolization and from surgery on a spinal AVM. It is generally performed in a hospital operating room, with the operative report describing the malformation, its location, and the surgical treatment performed.
Select this code when the case meets the simple category in the intracranial AVM surgery family; do not choose it solely from lesion size. Documentation should establish the intracranial site, the AVM treated, and the operative work supporting the simple classification. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. When multiple procedures subject to the standard reduction are performed in the same session, the highest-valued is paid in full and the others at 50%. Assistant-at-surgery payment may be available; co-surgeon payment requires supporting documentation, and team-surgery payment is not permitted.

61680 billing questions
How do I distinguish this from 61682?
Both describe surgery for an intracranial AVM. Use 61680 for the simple category and 61682 when the operative case meets the complex category; document the work and factors supporting the classification.
Is this the code for an intracranial dural fistula?
No. This code is for an intracranial AVM. Surgery for an intracranial dural arteriovenous fistula is represented in the 61690/61692 family.
Does this include catheter embolization?
No. This code represents open surgical treatment. Catheter-based embolization of a CNS lesion is a separate endovascular service, such as 61624, when performed and reportable.
What documentation supports reporting 61680?
The operative report should identify the intracranial AVM and its location, describe the surgical treatment performed, and support classification in the simple rather than complex category.
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-surgeon payment requires supporting documentation; team-surgery payment is not permitted.
