ICD-10 Code I70.738 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of other part of lower leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.738 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration of other part of lower leg
What it is
This code identifies atherosclerosis affecting a non-coronary bypass graft in the right leg, with an associated ulcer on another part of the lower leg. It reflects both the graft disease and the ulcer complication.
Clinical signs
Common findings include reduced limb perfusion, graft narrowing or occlusion, and a lower-leg ulcer that is documented as related to the vascular disease. Clinical features vary; refer to documentation.
When to use this code
Use this code when the record clearly states atherosclerosis in a right-leg bypass graft and an ulcer on another part of the lower leg. You should also confirm the ulcer location and that the graft type is not otherwise specified. If the documentation does not link the ulcer to the vascular condition, check documentation.
Do not use for
Do not use this code for native artery disease without a bypass graft, or for ulcers not documented as associated with the graft atherosclerosis. Check documentation if the graft side, ulcer site, or causal relationship is unclear.
Coding tip
Verify laterality, graft type, and ulcer site together before assigning I70.738.
