Varicose veins of right lower extremity w ulcer of unsp site

This code signifies the presence of abnormally dilated and tortuous veins in the right lower limb, complicated by an open sore or lesion on an unspecified location of that same extremity. This ulceration is directly attributable to the underlying venous insufficiency.

Apply this code when documentation clearly indicates varicose veins affecting the right leg, along with an associated ulcer where the specific anatomical site of the ulcer (e.g., ankle, calf) is not documented. This code is appropriate when the physician explicitly links the ulcer to the varicose vein disease.

• Ensure the documentation specifies "right lower extremity" and confirms the presence of an ulcer.
• If the ulcer's specific site is documented (e.g., ankle, calf), a more specific code from the I83.01- series should be used.
• Always sequence this code after any underlying cause of the varicose veins if applicable, though often the varicose veins themselves are the primary diagnosis.
