61680 AVM surgery Medicare reimbursement rates in Michigan

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.
