ICD-10 Code I70.75 – Atherosclerosis of other type of bypass graft(s) of other extremity with ulceration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.75 – Atherosclerosis of other type of bypass graft(s) of other extremity with ulceration
What it is
This code identifies atherosclerosis affecting a bypass graft in an extremity other than the leg or arm categories specified elsewhere, with an associated ulceration. It means the graft has narrowed or become blocked by plaque, and the limb has an ulcer linked to poor blood flow.
Clinical signs
Findings may include a nonhealing ulcer over the affected extremity, diminished perfusion, and evidence of peripheral arterial disease in the bypass graft. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record states atherosclerosis of a bypass graft in another extremity and documents ulceration. You should code it only when the ulcer is linked to the graft disease, not when ulceration is unrelated. Check documentation for the exact graft site and laterality if recorded.
Do not use for
Do not use this code for atherosclerosis without ulceration, or for ulcers from pressure, venous, diabetic, or traumatic causes. If the graft type or extremity is unclear, check documentation.
Coding tip
Confirm that both the bypass graft atherosclerosis and ulceration are documented together before assigning I70.75.
