BillablePhlebitis and thrombophlebitis of other deep vessels of left lower extremity
HCC Category Mapping
What This Code Means
Inflammation and blood clot formation in other deep veins of the left lower leg beyond the calf muscle area.
Coding Tips
- •Verify left laterality is documented; this code is specific to the left lower extremity
- •Document the specific deep vessel involved (popliteal, femoral, etc.) to support medical necessity and treatment decisions
Clinical Significance
Deep vein thrombophlebitis of the lower extremity involves both inflammation and clot formation in the deep venous system, carrying risk of clot propagation and pulmonary embolism. This condition requires anticoagulation therapy and ongoing vascular monitoring, reflecting significant resource utilization. Accurate coding is essential for risk adjustment as it indicates chronic vascular disease burden requiring sustained medical management.
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
- ✓Laterality (right or left) clearly specified in provider documentation
- ✓Documentation distinguishing deep vein thrombophlebitis from superficial thrombophlebitis
- ✓Assessment of risk factors (immobility, recent surgery, malignancy, hypercoagulable state, oral contraceptive use)
