0.000What This Code Means
Inflammation and blood clot formation in the left tibial vein, which runs through the lower leg near the shinbone.
Coding Tips
- •Ensure documentation specifies left-sided involvement; do not use this code for right or bilateral cases
- •Tibial veins are among the most distal deep veins of the lower extremity
Clinical Significance
Phlebitis and thrombophlebitis of the left 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 — left 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
