Chronic embolism and thrombosis of deep veins of l up extrem

This code signifies the persistent presence of a blood clot (thrombus) or an embolus within the deep venous system of the patient's left arm. This chronic condition can lead to ongoing symptoms such as swelling, pain, and skin changes in the affected extremity.

Apply this code when documentation explicitly states a chronic deep vein thrombosis (DVT) or embolism affecting the left upper extremity. This diagnosis is typically supported by imaging studies (e.g., ultrasound, venography) confirming the presence and chronicity of the clot.

• Differentiate between acute (I82.222) and chronic conditions; documentation must specify "chronic."
• Ensure the laterality is correctly identified as "left upper extremity."
• Consider any associated complications, such as post-thrombotic syndrome, and code them additionally.
