Chronic embolism and thombos unsp veins of up extrem, bi

This code signifies the persistent presence of a blood clot (thrombosis) or a traveling clot (embolism) within an unspecified vein of both upper extremities. This condition is chronic, meaning it has been ongoing or recurrent over an extended period, affecting both arms.

Apply this code when documentation clearly indicates a chronic venous embolism or thrombosis affecting both the right and left upper extremities, and the specific vein involved is not identified. This code is appropriate when the physician's notes confirm the chronicity and bilaterality of the condition without further anatomical specificity.

• Ensure documentation explicitly states "chronic" and "bilateral" for upper extremity venous embolism/thrombosis.
• Avoid using this code if a specific vein (e.g., subclavian, axillary) is documented; instead, use a more specific code from the I82.7- series.
• Do not use for acute events; refer to codes within the I82.2- or I82.3- series for acute upper extremity venous thrombosis.
