Chronic embolism and thombos of deep veins of up extrem, bi

This code signifies the presence of persistent blood clots or embolic material within the deep venous system of both upper extremities. These clots obstruct normal blood flow, leading to chronic symptoms such as swelling, pain, and venous insufficiency in both arms.

Apply this code when documentation clearly indicates a long-standing or recurrent deep vein thrombosis (DVT) or embolism affecting the deep veins of both the left and right upper limbs. Supporting documentation should include imaging reports (e.g., ultrasound, venography) confirming chronic deep vein occlusion or thrombus in both arms, along with clinical notes describing chronic symptoms.

• Ensure documentation specifies "chronic" and "bilateral" involvement of deep veins in the upper extremities.
• Differentiate from acute embolism/thrombosis codes (I82.21-I82.29) which describe recent clot formation.
• Do not use for superficial vein thrombosis; this code is specific to deep veins.
