BillableChronic embolism and thrombosis of popliteal vein, bilateral
HCC Category Mapping
What This Code Means
A blood clot that has formed and persists in both popliteal veins (veins behind the knees on both sides).
Coding Tips
- •The '3' in the fifth position indicates bilateral involvement; verify documentation confirms clots in both legs.
- •This code is more specific than unspecified popliteal codes and should be used when bilateral disease is clearly documented.
Clinical Significance
Chronic popliteal vein thrombosis involves a persistent clot in the major vein behind the knee, which serves as the transition point between proximal and distal deep venous systems. This location is clinically significant because popliteal vein thrombosis carries meaningful risk of post-thrombotic syndrome and may impair venous return from the entire lower leg. Accurate documentation of chronic popliteal vein thrombosis is important for capturing vascular disease complexity in risk adjustment.
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., popliteal)
- ✓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
