Chronic venous insufficiency (CVI) affects an estimated 40% of US adults. A comprehensive duplex exam is the gold standard for diagnosis, severity assessment, and treatment planning.
CEAP Classification Context
Clinical class ranges from C0 (no visible disease) to C6 (active ulceration). Most insurance carriers require C2 or higher plus documented reflux for treatment authorization. Build required fields into your report template.
Complete Exam Sequence
Start with the deep system: CFV, femoral vein, popliteal vein, and tibial veins. Assess compressibility (rule out DVT) and reflux. Move to the superficial system: SFJ, full GSV, SPJ, SSV, AASV, and tributaries. Finish with perforators: medial calf and thigh for incompetent perforators.
- MX7/M8 Elite: Use iWorks to create a standardized CVI protocol.
- Resona i9T: V Flow at junctions provides hemodynamic assessment without manual angle correction.
- Consona N9: Built-in vascular measurement package with structured report templates.
Documentation for Insurance Authorization
Required fields: reflux duration exceeding 0.5 seconds in the target vein, CEAP clinical class, symptoms, and failed conservative therapy (compression 3-6 months).
