0.000What This Code Means
Inflammation and blood clot formation affecting both peroneal veins on both sides of the lower legs.
Coding Tips
- •Bilateral coding requires clear documentation confirming involvement of both peroneal veins; do not assume from unilateral findings
- •Peroneal vein thrombosis may be associated with calf trauma or prolonged immobility
Clinical Significance
Phlebitis and thrombophlebitis of the bilateral peroneal vein represents distal deep vein thrombosis in the lateral calf. The peroneal veins are paired deep veins running alongside the fibula. While considered lower risk than proximal deep vein thrombosis, peroneal vein thrombosis can extend into the popliteal vein and requires clinical decision-making about anticoagulation versus surveillance based on individual risk factors.
Documentation Requirements
- ✓Duplex ultrasound confirming peroneal vein thrombosis
- ✓Laterality — bilateral peroneal vein documented
- ✓Acuity — acute vs. chronic thrombosis
- ✓Assessment of clot extent and risk for proximal propagation
- ✓Clinical decision documentation for anticoagulation vs. serial surveillance
- ✓Risk factor assessment including recent immobility, surgery, or malignancy
- ✓Follow-up plan including repeat imaging if surveillance approach chosen
Commonly Confused Codes
I80.23x — Tibial vein thrombophlebitis: different paired deep veins in the calfI80.25x — Calf muscular vein thrombophlebitis: intramuscular veins (soleal, gastrocnemius) rather than axial veinsI80.22x — Popliteal vein thrombophlebitis: more proximal, higher risk locationI80.0x — Superficial vessel thrombophlebitis: superficial veins, not deepI80.20x — Unspecified deep vessels: less specific; use I80.24x when peroneal is documented
