2026 ICD-10-CM Diagnosis Code I83.012 – Varicose veins of right lower extremity with ulcer of calf
What it is
This code identifies varicose veins in the right leg when there is a documented ulcer on the calf. Use it when the record links the ulcer to venous disease on the right lower extremity.
Clinical signs
Typical findings include visible, enlarged, tortuous veins and a chronic ulcer on the right calf. Clinical features vary; refer to documentation for venous insufficiency, ulcer location, and laterality.
When to use this code
Use I83.012 when the provider documents varicose veins of the right lower extremity with a calf ulcer caused by or associated with venous disease. The ulcer should be described as on the calf and on the right side. If the note does not clearly connect the ulcer to varicose veins, check documentation.
Do not use for
Do not use this code for varicose veins without an ulcer, or for ulcers from trauma, pressure, or arterial disease. If the ulcer site or cause is unclear, check documentation.
Coding tip
Confirm both laterality and ulcer location in the note before assigning this code.
