Inflammation and blood clot formation in the femoral vein (major vein in the thigh) when the specific leg is not documented.
Coding Tips
Clinical Significance
Phlebitis and thrombophlebitis of the unspecified femoral vein represents deep vein thrombosis in a proximal lower extremity vein, which carries significant risk for pulmonary embolism. The femoral vein is a major deep vein, and thrombosis here is considered a high-risk deep vein thrombosis requiring anticoagulation therapy. This condition reflects acute vascular disease burden and ongoing management needs for risk adjustment.
Documentation Requirements
- ✓Duplex ultrasound or other imaging confirming femoral vein thrombosis
- ✓Laterality documentation — query provider for right vs. left specification
- ✓Distinction between acute, subacute, and chronic thrombosis
- ✓Assessment for concurrent pulmonary embolism
- ✓Anticoagulation therapy plan with specific agent, dose, and duration
- ✓Evaluation of underlying risk factors (immobility, malignancy, thrombophilia, surgery)
- ✓Follow-up imaging plan if applicable
