HCC Category Mapping
What This Code Means
Inflammation and blood clot formation in an unspecified deep vein of the left leg.
Coding Tips
- •This is a non-specific deep vein code for the left lower extremity
- •Query the provider if the specific deep vein can be identified for more precise coding
Clinical Significance
Phlebitis and thrombophlebitis of unspecified deep vessels of the left lower extremity indicates deep vein thrombosis without specification of the exact vein involved. Deep vein thrombosis is a significant condition carrying risk of pulmonary embolism and post-thrombotic syndrome. While this code captures the deep vein thrombosis, providers should be queried for the specific vein (femoral, popliteal, tibial) to enable more precise coding.
Documentation Requirements
- ✓Imaging confirmation of deep vein thrombosis (duplex ultrasound or CT venography)
- ✓Laterality — left side documented
- ✓Query provider for specific deep vein involvement when possible
- ✓Acuity — acute, subacute, or chronic thrombosis
- ✓Evaluation for pulmonary embolism
