What This Code Means

This code describes inflammation and blood clots in the deep veins of both legs. It indicates a serious condition where blood vessels deep within the lower extremities on both sides are affected by clotting and inflammation.

Coding Tips

•Verify documentation specifies BOTH legs are affected; if only one leg is involved, use a different code (I80.291 for right or I80.292 for left)
•Ensure the provider documents this as a deep vein thrombophlebitis (DVT) rather than superficial thrombophlebitis, as this affects coding specificity and clinical severity

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
✓Explicit documentation that both lower extremities are affected
✓Documentation distinguishing deep vein thrombophlebitis from superficial thrombophlebitis
✓Assessment of risk factors (immobility, recent surgery, malignancy, hypercoagulable state, oral contraceptive use)

Commonly Confused Codes

I80.10-I80.13 — Phlebitis of femoral vein; use when specifically the femoral vein is involved rather than other deep calf vessels I80.20-I80.209 — Phlebitis of unspecified deep vessels; less specific codes that do not identify the particular deep vein involved I82.40x-I82.4Zx — Acute embolism and thrombosis of deep veins of lower extremity; use for acute DVT without the inflammatory phlebitis component I80.0- — Phlebitis of superficial vessels of lower extremities; use for superficial vein involvement rather than deep veins I87.01x — Postthrombotic syndrome; use for chronic sequelae of prior DVT, not active thrombophlebitis
