Embolism and thrombosis of superficial veins of r low extrem

This code signifies the presence of a blood clot (thrombus) or an occluding mass (embolus) within a superficial vein of the patient's right lower limb. This condition typically involves veins closer to the skin surface, such as the great or small saphenous veins, rather than deeper venous structures.

Apply this code when documentation clearly indicates a diagnosis of superficial venous thrombosis or embolism affecting the right lower extremity. Supporting documentation should specify the laterality (right) and the superficial nature of the affected veins, often presenting with localized pain, redness, and swelling.

• Ensure documentation specifies "superficial" veins; do not use for deep vein thrombosis.
• Verify laterality is explicitly stated as "right lower extremity."
• Distinguish from phlebitis without thrombosis, which would use a different code from the I80 series.
