0.000What This Code Means
Inflammation and blood clot formation affecting both tibial veins in both lower legs.
Coding Tips
- •Bilateral coding requires explicit documentation of involvement in both legs; verify imaging or clinical findings support bilateral diagnosis
- •This represents a more extensive thrombotic process; ensure appropriate workup for underlying causes
Clinical Significance
Phlebitis and thrombophlebitis of the bilateral tibial vein represents distal deep vein thrombosis of the lower leg. While distal deep vein thrombosis generally carries lower risk of pulmonary embolism compared to proximal deep vein thrombosis, it can propagate proximally if untreated. Management may involve anticoagulation or serial surveillance depending on clinical context and risk factors.
Documentation Requirements
- ✓Duplex ultrasound confirming tibial vein thrombosis
- ✓Laterality — bilateral tibial vein documented
- ✓Specification of anterior or posterior tibial vein when documented
- ✓Acuity — acute vs. chronic thrombosis
- ✓Risk assessment for proximal propagation
- ✓Treatment decision — anticoagulation vs. serial surveillance with rationale
- ✓Follow-up imaging plan to assess for clot extension
Commonly Confused Codes
I80.22x — Popliteal vein thrombophlebitis: more proximal deep vein, different management implicationsI80.24x — Peroneal vein thrombophlebitis: different calf vein with separate codeI80.25x — Calf muscular vein thrombophlebitis: soleal or gastrocnemius vein, not tibialI80.0x — Superficial vessel thrombophlebitis: superficial veins onlyI80.20x — Unspecified deep vessels: less specific; use I80.23x when tibial vein is identified
