ICD-10 Code I70.334 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of heel and midfoot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.334 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of heel and midfoot
What it is
This code identifies atherosclerosis affecting an unspecified bypass graft in the right leg, with an associated ulcer on the heel and midfoot. Use it when the record links the graft disease to that specific ulcer location.
Clinical signs
Typical findings include reduced blood flow in the grafted limb, peripheral ischemic changes, and a nonhealing ulcer on the heel or midfoot. Clinical features vary; refer to documentation.
When to use this code
Use I70.334 when the provider documents atherosclerosis in a bypass graft of the right leg and also documents ulceration of the heel and midfoot. The ulcer must be tied to this vascular disease in the record. If the graft type is not specified, this code still applies.
Do not use for
Do not use this code for ulcers without documented atherosclerosis, or for disease in the left leg or another site. Check documentation if the ulcer location or vascular cause is unclear.
Coding tip
Verify that the ulcer site is heel and midfoot and that the bypass graft is on the right leg before assigning this code.
