Chronic embolism and thombos of superfic vn unsp up extrem

This code signifies the presence of a long-standing blood clot or blockage within a superficial vein of an undifferentiated upper limb. This condition is characterized by the persistent obstruction of blood flow in the veins closer to the skin surface, rather than the deeper venous system. It implies a non-acute, ongoing process of venous occlusion.

Use this code when documentation clearly indicates a chronic, rather than acute, embolism or thrombosis affecting a superficial vein of an upper extremity, and the specific arm (left or right) is not specified. Supporting documentation would include physician notes detailing the chronicity of the condition, imaging reports confirming the presence of a superficial venous thrombus, and the absence of laterality.

• Ensure the documentation explicitly states "chronic" to differentiate from acute events.
• Avoid using this code if the laterality (left or right upper extremity) is documented; instead, select the more specific I82.711 or I82.712.
• Do not confuse with deep vein thrombosis (DVT) codes; this code is specific to superficial veins.
