0.000What This Code Means
A blood clot that suddenly forms in the right thigh vein (femoral vein), blocking blood flow in that leg.
Coding Tips
- •Verify documentation specifies 'right' side; if bilateral or unspecified, use different code
- •Confirm acute onset is documented; chronic thrombosis uses different code category
Clinical Significance
Acute thrombosis of the femoral vein, a major proximal deep vein in the thigh, represents a high-risk deep vein thrombosis with significant potential for pulmonary embolism. Proximal deep vein thrombosis carries greater morbidity than distal clots and typically requires aggressive anticoagulation, potential catheter-directed thrombolysis, and close monitoring. Capturing this diagnosis accurately reflects the acute care needs and ongoing vascular disease risk of these patients.
Documentation Requirements
- ✓Clinical diagnosis of venous thrombosis or thrombophlebitis clearly documented by the treating provider
- ✓Diagnostic confirmation via duplex ultrasonography, CT venography, MR venography, or venography with imaging findings described
- ✓Current treatment plan including anticoagulation regimen with specific medication, dose, and duration
- ✓Documentation of acute onset with date of symptom onset or diagnosis establishing the acute nature
- ✓Laterality (right or left) clearly specified in provider documentation
- ✓Assessment of risk factors (immobility, recent surgery, malignancy, hypercoagulable state, oral contraceptive use)
