Embolism and thombos of superfic veins of low extrm, bi

This code signifies the presence of blood clots (thrombosis) or blockages from traveling debris (embolism) within the superficial venous system of both lower limbs. These clots obstruct blood flow in veins located close to the skin surface, such as the great saphenous vein or small saphenous vein. The condition can cause localized pain, swelling, and redness in both legs.

Use this code when documentation clearly indicates superficial venous thrombosis or embolism affecting both lower extremities. This typically arises from conditions like varicose veins, prolonged immobility, or trauma. Supporting documentation should specify "bilateral" involvement of superficial veins.

• Differentiate from deep vein thrombosis (DVT); this code is specifically for superficial veins.
• Ensure the documentation explicitly states "bilateral" involvement; otherwise, a unilateral code would be more appropriate.
• Consider sequencing this code after any underlying cause, such as varicose veins with inflammation (I83.1- or I83.2-), if applicable and documented.
