ICD-10 Code I70.333 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.333 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of ankle
What it is
This code identifies atherosclerotic narrowing or blockage in an unspecified bypass graft in the right leg, with an ulcer located at the ankle. It reflects vascular disease affecting the graft and the associated skin breakdown.
Clinical signs
Findings may include poor circulation in the right leg, diminished pulses, leg pain, or delayed wound healing. Clinical features vary; refer to documentation for the bypass graft and ulcer location.
When to use this code
Use this code when the record clearly documents atherosclerosis in an unspecified bypass graft of the right leg and an ulcer of the ankle. The ulcer must be linked to the vascular disease, not coded separately as an unrelated wound.
Choose it when laterality is right and the site is the ankle. If the graft type or ulcer detail is missing, check documentation before assigning the code.
Do not use for
Do not use this code for atherosclerosis without a bypass graft, or for ulcers not associated with the vascular condition. Do not assume the graft type if documentation says something different.
Coding tip
Verify the operative history, laterality, and ulcer site together before coding.
