Chr emblsm and thombos of superfic veins of up extrem, bi

This code signifies the presence of persistent blood clots (thrombosis) or emboli within the superficial venous system of both upper extremities. These are long-standing conditions, not acute events, affecting veins visible or palpable just beneath the skin.

Apply this code when documentation clearly indicates chronic superficial venous thrombosis or embolism affecting both arms. Supporting documentation should specify the chronicity and bilateral involvement, often found in vascular studies or physician notes detailing a history of such clots.

• Ensure documentation explicitly states "chronic" and "bilateral" involvement of superficial veins in the upper extremities.
• Distinguish from acute events (I82.A-I82.B) and deep vein thrombosis (I82.2-I82.4).
• Do not use if only one upper extremity is affected; specific codes exist for unilateral involvement.
