Phlbts and thombophlb of superfic vessels of low extrm, bi

This code signifies inflammation of a superficial vein, accompanied by thrombus formation, affecting both lower extremities. It describes a condition where blood clots develop in veins close to the skin surface in both legs, leading to pain, redness, and swelling.

Apply this code when documentation clearly indicates superficial phlebitis and thrombophlebitis present in both the right and left lower limbs. This diagnosis is typically supported by physical examination findings of palpable, tender, cord-like veins in both legs, often confirmed by ultrasound.

• Ensure documentation specifies "bilateral" involvement of the lower extremities.
• Distinguish from deep vein thrombosis (DVT), which involves deeper veins and has different coding.
• Look for specific anatomical sites (e.g., great saphenous vein) if documented, but this code is for general bilateral superficial involvement.
