Acute embolism and thombos unsp veins of r up extrem

This code signifies the sudden blockage of an unspecified vein in the right upper extremity due to either an embolus (a traveling clot) or a thrombus (a stationary clot). This acute vascular event obstructs blood flow, potentially leading to pain, swelling, and functional impairment in the affected arm.

Apply this code when documentation clearly indicates an acute venous embolism or thrombosis affecting an unspecified vein of the right upper extremity. Supporting documentation typically includes imaging reports (e.g., ultrasound, venography) confirming the presence and location of the clot, along with physician notes detailing the acute onset of symptoms.

• Ensure the documentation specifies "acute" onset; chronic conditions would require a different code.
• Verify the laterality (right upper extremity) is explicitly stated.
• If the specific vein is identified (e.g., subclavian, axillary), a more specific code from the I82.6- series should be used.
