Vascular surgery practices leave revenue uncollected from global period errors, endovascular code mismatches, and revascularization denials, and improperly billed postoperative visits during global periods are a recurring audit finding.
Common Billing Challenges
These are the six billing failure points we see most often in vascular surgery practices, and the ones our team resolves systematically from day one.
Endovascular code selection mismatches against the operative report are a common audit finding, so the graft configuration, landing zones, and components documented have to match the code billed.
Billing a postoperative E/M during the 90-day global window without the right modifier is a false claim, not just a denial, OIG found average recoupment of $47,000 per practice on this pattern alone.
CLI procedures draw heavy denials; payers require documented Rutherford classification, ABI measurements, and conservative treatment history before they'll approve.
Major payers require prior auth plus a peer-to-peer review for lower extremity atherectomy, a 15-30 minute physician commitment per case that needs to be built into scheduling.
The higher-paying ruptured AAA repair code requires radiographic or intraoperative evidence of active bleeding, not just a symptomatic aneurysm, or the claim gets downcoded on audit.
Increased procedural services claims need the operative note to describe the specific additional work, estimated time, and complexity, a generic "procedure was difficult" doesn't hold up and invites recoupment plus interest.
Key Procedure Codes
Our coders hold specialty-specific credentials and train continuously on the codes that drive the most revenue, and the most denials, in vascular surgery.
| CPT Code | Description | Common Issue |
|---|---|---|
| 34701–34704 | Endovascular AAA repair, by device configuration | Config must match operative report exactly |
| 35081/35082 | Open AAA repair, standard / with rupture | 35082 requires documented rupture evidence |
| 35301 | Carotid endarterectomy (CEA) | 90-day global period tracking required |
| 37254–37299 | Lower extremity revascularization by territory (replaced 37220–37235 on January 1, 2026) | Prior auth + peer-to-peer often required; confirm the auth maps to the 2026 code |
| Modifier 24/78/79 | Global period exceptions | Missing modifier on global-window E/M = false claim |
| Modifier 22 | Increased procedural services | Needs quantified additional-work documentation |
