ICD-10 Code I70.733 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of ankle (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.733 – Atherosclerosis of other 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 other-type bypass graft in the right leg, with a documented ankle ulcer. Use it when the graft disease and ulcer are both specified in the record.
Clinical signs
Typical findings include evidence of peripheral arterial disease in the graft and a nonhealing ankle ulcer. Clinical features vary; refer to documentation for laterality, graft type, and ulcer location.
When to use this code
Use this code when the provider documents atherosclerosis affecting a bypass graft in the right leg and an ulcer at the ankle. It fits cases where the ulcer is linked to the graft-related arterial disease. If the graft type or ulcer site is unclear, check documentation.
Do not use for
Do not use this code for atherosclerosis without a documented ankle ulcer, or for ulcers caused by venous, diabetic, pressure, or traumatic conditions. Also avoid it if the bypass graft site is not the right leg.
Coding tip
Verify both the graft location and the ulcer site in the note before assigning I70.733.
