ICD-10 Code I70.739 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of unspecified site (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.739 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of unspecified site
What it is
This code identifies atherosclerotic disease in a nonautologous bypass graft in the right leg, with an associated ulcer but no specified ulcer site. Use it when the graft is affected by plaque buildup and the documentation links the ulcer to that condition.
Clinical signs
Findings may include diminished limb perfusion, graft-related ischemic changes, and a documented ulcer on the right leg. Clinical features vary; refer to documentation.
When to use this code
Use I70.739 when the record states atherosclerosis of another type of bypass graft in the right leg and notes an ulcer, but the ulcer location is not specified. The diagnosis should clearly connect the ulcer to the graft disease. If the chart does not identify the graft type or laterality, check documentation.
Do not use for
Do not use this code for native artery atherosclerosis, ulcers without documented graft disease, or bypass graft disease in a different limb. Check documentation if the ulcer site is specified elsewhere.
Coding tip
Verify laterality, graft type, and ulcer linkage before assigning I70.739.
