Acute embolism and thrombosis of superfic vn unsp up extrem

This code signifies the sudden blockage of a superficial vein in an unspecified upper limb due to a blood clot. This condition typically presents with acute pain, tenderness, redness, and swelling along the course of the affected vein, often visible or palpable just beneath the skin. It is distinct from deep vein thrombosis (DVT) as it involves veins closer to the surface.

Apply this code when documentation clearly indicates an acute thrombotic event within a superficial vein of an upper extremity, without specifying laterality (e.g., "acute superficial thrombophlebitis of the arm"). Supporting documentation should include physician notes detailing the acute onset of symptoms and physical examination findings consistent with superficial venous thrombosis.

• Ensure the documentation specifies "acute" to differentiate from chronic conditions.
• Avoid using this code if the laterality (left or right) of the affected upper extremity is documented; instead, use the more specific codes (I82.611 or I82.612).
• Do not confuse with deep vein thrombosis (DVT) codes, which involve different venous systems and carry different clinical implications.
