What 61613 covers

A cerebrovascular or skull-base neurosurgeon treats an aneurysm located in the portion of the carotid artery within the cavernous sinus by surgically trapping it and removing the aneurysm. A muscle graft may be used as part of the trapping procedure. This is an operating-room service for a complex intracranial vascular condition, rather than an endovascular catheter procedure or excision of a nonvascular skull-base lesion.

Report the code when the operative record supports treatment of an intracavernous carotid aneurysm by trapping with aneurysm removal. The code has a 90-day global period, including the day-before preoperative visit and 90 days of related postoperative care. For multiple procedures in one session, Medicare pays the highest-valued procedure in full and reduces other procedures to 50%. Bilateral reporting with modifier 50 is paid at 150%. An assistant at surgery may be paid; co-surgeon payment requires supporting documentation, and team surgery is permitted.

61613 billing questions

What distinguishes this from code 61611?

This code is for surgical trapping of an intracavernous carotid aneurysm with removal of the aneurysm. Code 61611 describes transection or ligation of the carotid artery in the cavernous sinus, without repair.

Can aneurysm removal be billed separately from the trapping?

Aneurysm removal is included in this service. The operative report should show the aneurysm site and the trapping and removal performed.

How does the 90-day global period affect postoperative billing?

The day-before preoperative visit and 90 days of related postoperative care are included in the global period.

How are other procedures in the same session paid?

Medicare pays the highest-valued procedure in full and reduces the other procedures to 50% under the standard multiple procedure rule.

What supports co-surgeon payment?

Co-surgeon payment requires supporting documentation. The CMS facts also permit team surgery and allow payment for an assistant at surgery.

How is bilateral performance reported?

For bilateral performance, report modifier 50; CMS pays the procedure at 150%.
