ICD-10 Code I70.335 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of other part of foot (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.335 – Atherosclerosis of unspecified type of bypass graft(s) of the right leg with ulceration of other part of foot
What it is
This code describes atherosclerotic narrowing or blockage in an unspecified bypass graft in the right leg, with an ulcer on another part of the foot. Use it when the record links the graft disease and the foot ulcer.
Clinical signs
Typical findings include reduced blood flow to the right lower extremity, poor wound healing, and a foot ulcer in a non-heel area. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents atherosclerosis affecting a bypass graft in the right leg and specifies an ulcer of another part of the foot. The ulcer and vascular disease should both be documented as related. Check documentation if the graft type is unclear or the ulcer site is not specified.
Do not use for
Do not use this code for atherosclerosis without a documented foot ulcer, or for ulcers unrelated to arterial disease. Do not use when the bypass graft is in a different limb or the ulcer location is not “other part of foot.”
Coding tip
Verify laterality, graft type, and ulcer location in the note before assigning I70.335.
