Vascular Surgery BillingComplete Coding & Revenue Guide (2026)Top CPT codes with current RVU data, denial patterns, modifier rules, bundling pitfalls, and revenue opportunities for vascular surgery practices.
Top CPT Codes
The highest-value vascular surgery CPT codes with current RVU data and Medicare payment from the CY 2026 Physician Fee Schedule. Click any code for the full payment, bundling, and modifier guide.
Most practices under-capture revenue on these codes through downcoding, missed modifier 25, stale fee schedules, or misapplied bundling. Our coders audit every line against the documentation before submission so the revenue earned actually gets billed.
Bundling Pitfalls
5 trapsThe code pairs that trigger NCCI edits and CO-97 denials in vascular surgery. Know these before billing.
37224: 37225: Tibial/peroneal revascularization: 37228 (angioplasty) bundles with 37229 (atherectomy, add-on). If doing both, bill 37228 + 37229. Cannot bill standalone atherectomy without angioplasty base.
93880: 93882: Complete carotid duplex (93880) bundles with limited (93882). If you do complete bilateral, bill 93880. Cannot bill 93880 + 93882 same day.
36821: 36831: AV fistula creation (36821) on same day as fistula revision (36831): these are different procedures. Can bill both if on different sites. Same site = only one.
37236: 37238: Venous stent (37238) and arterial stent (37236) — different codes. Arterial stent: 37236 first vessel + 37237 each additional. Venous: 37238 first vessel + 37239 each additional.
35301: 35302: Carotid endarterectomy (35301) includes the vessel closure. Patch angioplasty (35302) is separately billable ONLY if documented as a distinct additional procedure.
CO-97 bundling denials are recoverable with correct modifier documentation. Most billers write them off. We work each one against the clinical record and resubmit with the right modifier 25 or 59 path.
Modifier Guidance
When to apply each modifier in vascular surgery claims. Wrong modifier application is the top single-line denial trigger and a leading audit target.
Increased complexity — use for heavily calcified vessels, hostile groin (multiple prior surgeries), or unusual anatomy requiring extended operative time.
Professional component — use when interpreting vascular duplex performed by vascular lab at hospital.
Bilateral — use for bilateral lower extremity interventions, bilateral carotid duplex (93880-50). Payment = 150% of unilateral.
Two surgeons — use for complex aortic procedures (EVAR with renal/visceral involvement requiring two vascular surgeons).
Return to OR for complication — use for thrombectomy of fresh bypass graft within 90-day global.
Distinct procedure — CRITICAL in vascular surgery. Multiple vessels in same session: each vessel intervention is separately billable. Document each vessel treated separately.
Revenue Opportunities
6 playsThe billing codes and services most vascular surgery practices under-capture. Each one is a recurring revenue lift, not a one-time fix.
Endovascular interventions: Multi-vessel lower extremity intervention generates $5,000-15,000 per case (catheterization + multiple angioplasties + stents + atherectomy). Volume practices doing 3-5 cases/week = $1M+/year.
Vascular laboratory: In-office accredited vascular lab generates $150-300 per duplex study. With 10-15 studies/day = $400K-1M/year. Requires IAC accreditation.
Dialysis access: Fistula creation (36821) pays $1,500-2,500. Fistulagram/revision (36831/36901) pays $800-1,500. With 5 access procedures/week = $250K-500K/year.
Wound care center: Vascular surgeons treating chronic wounds (venous ulcers, diabetic foot ulcers) bill E/M + wound care (97597/97598) + compression therapy. Revenue: $200-400/visit x 2 visits/week x 50 patients = $1M+/year.
EVAR revenue: Endovascular aneurysm repair (34701+) generates $8,000-15,000 in professional fees + device revenue. High-volume centers doing 2-3/week = significant revenue.
Office-based endovascular suite (OBL): Physicians who invest in office-based labs capture both professional AND facility fees. Revenue doubles vs hospital-based practice.
Documentation Checklist
What the chart must contain to support billing. Missing documentation means audit vulnerability.
- Carotid endarterectomy (35301): Document indication (symptomatic vs asymptomatic), percent stenosis (by duplex + CTA/MRA), contralateral disease, neurologic exam, operative technique (standard vs eversion), shunt use, patch closure, and completion duplex/angiogram.
- Lower extremity revascularization (37220-37231): Document limb status (Rutherford classification), pre-intervention ABI, lesion characteristics (length, location, calcification, chronic total occlusion), intervention performed on each vessel (angioplasty, stent, atherectomy), and post-intervention results (residual stenosis, flow restoration).
- EVAR/aortic (34701-34703): Document aneurysm size, morphology (neck length, angulation, access vessel diameter), device type and size, deployment technique, completion angiogram, and endoleak assessment.
- Dialysis access (36818-36831): Document access type (AVF vs AVG), vessel assessment, anastomosis technique, thrill/brill confirmation, and maturation plan.
- Vascular duplex (93880-93971): Document indication, vessels examined, velocity measurements, stenosis grading (per SRU criteria), and clinical correlation.
Coding Workflow
Step by step approach for coding vascular surgery encounters correctly.
1. Determine procedure type: open vs endovascular vs diagnostic. 2. For endovascular interventions: bill per-vessel. Each vessel territory (iliac, femoral, popliteal, tibial) is separately billable. Document selective catheterization codes (36245-36248) + intervention codes (37220-37231). 3. For carotid: CEA (35301) or CAS (37215/37216) — different code families, never mix. 4. For aortic: open repair (35081/35082) vs EVAR (34701-34703) — verify device-specific coding. 5. For access: creation (36818-36821) vs revision (36831-36833) vs declot (36831). 6. Bill vascular duplex same day as intervention only if it was a SEPARATE diagnostic study (not the completion study, which is included in the intervention).
