Embolism and thrombosis of superficial vn unsp low extrm

This code signifies the presence of a blood clot (thrombosis) or a blockage by an embolus within a superficial vein of an unidentifiable lower limb. This condition typically presents as localized pain, redness, and swelling along the course of the affected vein, without involvement of the deeper venous system.

Apply this code when documentation clearly indicates superficial venous thrombosis or embolism in a lower extremity, but the specific leg (right or left) is not specified. This is appropriate for cases like superficial thrombophlebitis where the laterality is not documented.

• Ensure the documentation explicitly states "superficial" involvement; do not use for deep vein thrombosis (DVT).
• Avoid this code if the laterality (right or left lower extremity) is documented; instead, use the more specific codes within the I82.81- series.
• Consider co-reporting with codes for underlying causes or risk factors, such as varicose veins (I83.-) or trauma, if applicable and documented.
