Chronic embolism and thrombosis of deep vein of r low extrem

This code signifies a persistent or long-standing blockage within a deep vein of the right lower extremity, excluding the femoral, iliac, and popliteal veins. This obstruction is caused by either an embolus (a traveling clot) or a thrombus (a clot formed in place). The "other specified" designation indicates the physician has identified a specific deep vein other than the major ones.

Use this code when documentation clearly states a chronic deep vein thrombosis or embolism affecting a specific, non-major deep vein of the right lower limb. This typically applies to conditions like chronic DVT of the peroneal, tibial, or calf veins. Supporting documentation should specify chronicity and the exact location of the affected deep vein.

• Ensure the documentation specifies "chronic" and identifies a deep vein in the right lower extremity other than the femoral, iliac, or popliteal.
• Distinguish carefully between acute and chronic conditions; acute DVT of other specified deep veins of the right lower extremity would be coded differently.
• Always review operative reports or imaging studies (e.g., venous duplex ultrasound) for precise anatomical location and chronicity.
