0.000What This Code Means
A blood clot that has formed and persists in both tibial veins (veins in the lower legs on both sides).
Coding Tips
- •The '3' in the fifth position indicates bilateral involvement; confirm documentation supports thrombosis in both tibial veins.
- •Bilateral tibial vein thrombosis is a significant finding that may impact treatment decisions.
Clinical Significance
Chronic tibial vein thrombosis represents a persistent deep vein thrombosis in the distal lower extremity venous system. Although distal deep vein thrombosis has traditionally been considered lower risk than proximal deep vein thrombosis, chronic tibial vein thrombosis can cause significant post-thrombotic symptoms and may propagate proximally. This diagnosis is relevant for risk adjustment as it demonstrates ongoing vascular disease requiring continued monitoring and treatment.
Documentation Requirements
- ✓Provider documentation explicitly stating 'chronic' deep vein thrombosis (not assumed from duration of treatment)
- ✓Clinical evidence supporting the diagnosis such as duplex ultrasound, venography, or other imaging results
- ✓Specific vein location documented (e.g., tibial)
- ✓Documentation confirming bilateral involvement (both extremities affected)
- ✓Current treatment plan including anticoagulation therapy and duration
- ✓Assessment and monitoring notes demonstrating the condition is being actively managed
- ✓Documentation of chronicity such as 'chronic,' 'old,' 'long-standing,' or history of prior acute deep vein thrombosis that has transitioned to chronic status
Commonly Confused Codes
I82.443 — Acute embolism and thrombosis of tibial vein; confirm documentation explicitly states chronicI82.55- — Chronic embolism and thrombosis of peroneal vein; the peroneal vein runs parallel to the tibial but is a separate vesselI82.53- — Chronic embolism and thrombosis of popliteal vein; the popliteal is more proximal than the tibial veinI82.5Z- — Chronic embolism of unspecified deep veins of distal lower extremity; use the tibial-specific code when documentation specifies the tibial vein
