Phlebitis and thombophlb of deep vessels of r low extrem

This diagnosis code signifies inflammation of a vein (phlebitis) accompanied by thrombus formation (thrombophlebitis) affecting deep veins in the right lower extremity, excluding those specifically categorized elsewhere (e.g., femoral, popliteal, tibial). It indicates a deep vein thrombosis (DVT) event occurring in other, less commonly specified deep venous structures of the right leg.

Apply this code when documentation clearly identifies a deep vein thrombophlebitis in the right lower extremity, and the specific vessel involved is not the femoral, popliteal, or tibial vein, but rather another deep venous structure. Supporting documentation should include imaging reports (e.g., duplex ultrasound) confirming the presence and location of the thrombus, along with physician notes detailing the diagnosis.

• Ensure the documentation explicitly states "deep" vessel and "right lower extremity."
• Distinguish from superficial thrombophlebitis, which codes to a different category (I80.0-).
• Always review imaging reports and physician notes for precise anatomical location to avoid miscoding with more specific DVT codes (e.g., femoral, popliteal, tibial).
