Varicose veins of right lower extremity with ulcer of thigh

This code signifies the presence of abnormally dilated and tortuous veins in the right lower extremity, specifically in the thigh region, which have led to the development of an open sore or lesion. This ulceration is a direct complication of the underlying venous insufficiency.

Apply this code when documentation clearly indicates varicose veins affecting the right lower extremity, with a specific ulcer located on the thigh. The physician's notes should confirm the causal relationship between the varicose veins and the ulcer.

• Ensure the documentation specifies the right lower extremity and the thigh as the ulcer location.
• Distinguish from ulcers due to arterial insufficiency or pressure, which have different ICD-10-CM codes.
• Consider additional codes for severity of the ulcer (e.g., non-pressure chronic ulcer stage) if documented.
