Varicose veins of left lower extremity with ulcer of thigh

This code signifies the presence of abnormally dilated and tortuous veins in the left lower extremity, specifically accompanied by an open sore or lesion located on the thigh. The ulceration is directly attributable to the underlying venous insufficiency.

Apply this code when documentation clearly indicates varicose veins affecting the left leg, with a specific ulcer located on the thigh. The physician's notes should confirm the causal relationship between the varicose veins and the ulcer. This code is appropriate for both initial encounters and subsequent care of this specific condition.

• Ensure the documentation specifies "left lower extremity" and "thigh" for the ulcer location.
• Do not use this code if the ulcer is on a different part of the left lower extremity (e.g., calf, ankle, foot).
• Always sequence this code first when the varicose vein with ulcer is the primary reason for the encounter.
