Chronic embolism and thombos of deep vein of low extrm, bi

This code signifies a long-standing blockage within a deep vein in both lower extremities, caused by either an embolus (traveling clot) or a thrombus (stationary clot). It refers to deep veins other than the femoral, popliteal, or tibial, indicating involvement of less commonly specified deep veins.

Apply this code when documentation confirms a chronic deep vein thrombosis (DVT) or embolism affecting both legs, specifically in deep veins not otherwise classified. Supporting documentation should clearly state the chronicity and bilateral involvement, along with the specific deep vein(s) if known and not covered by more specific codes.

• Ensure documentation specifies "chronic" and "bilateral" involvement of deep veins.
• Verify that the affected deep veins are not more precisely described by other I82.5 codes (e.g., femoral, popliteal, tibial).
• Do not use this code for acute or subacute conditions; look for codes within I82.4- for those scenarios.
