Chronic embolism and thombos unsp veins of r up extrem

This code signifies the presence of a long-standing blood clot within an unspecified vein of the patient's right upper extremity. This condition is chronic, meaning it has persisted over time, and can lead to impaired venous return and potential post-thrombotic syndrome in the affected limb.

Use this code when documentation clearly indicates a chronic venous embolism or thrombosis affecting the right upper extremity, but the specific vein (e.g., subclavian, axillary, brachial) is not identified. This typically follows imaging studies (e.g., ultrasound, venography) confirming the presence of a chronic clot without further anatomical specificity.

• Ensure the documentation specifies "chronic" and "right upper extremity."
• Avoid using this code if a more specific vein is identified; instead, use the appropriate code from the I82.71-I82.79 series.
• Always sequence this code after any underlying cause or associated conditions, such as a hypercoagulable state.
