ICD-10 Code I70.441 – Atherosclerosis of autologous vein bypass graft(s) of the left leg with ulceration of thigh (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.441 – Atherosclerosis of autologous vein bypass graft(s) of the left leg with ulceration of thigh
What it is
This code identifies atherosclerotic narrowing in an autologous vein bypass graft in the left leg, with an ulcer located on the thigh. Use it when the graft disease and ulceration are both documented.
Clinical signs
Findings may include reduced graft patency, diminished distal perfusion, and a documented ulcer on the left thigh. Clinical features vary; refer to documentation.
When to use this code
Use I70.441 when the provider documents atherosclerosis affecting an autologous vein bypass graft in the left leg and specifies ulceration of the thigh. The record should clearly link the graft disease and ulcer site. If the ulcer location or graft type is unclear, check documentation.
Do not use for
Do not use this code for native artery atherosclerosis without a bypass graft, or for ulcers not associated with the documented graft disease. Check documentation if the graft is not autologous vein.
Coding tip
Verify the bypass graft type, laterality, and ulcer location before assigning I70.441.
