ICD-10 Code I70.73 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.73 – Atherosclerosis of other type of bypass graft(s) of the right leg with ulceration
What it is
This code identifies atherosclerosis affecting a non-autologous bypass graft in the right leg, with an associated ulcer. It is used when the graft has plaque-related narrowing or blockage and the ulcer is documented.
Clinical signs
Typical findings include reduced blood flow in the right leg graft and a documented ulcer on the same limb. Clinical features vary; refer to documentation for location, severity, and whether tissue loss is present.
When to use this code
Use this code when the provider documents atherosclerosis in an other type of bypass graft of the right leg and also documents ulceration. The ulcer must be linked to the graft disease in the record. If the note does not clearly identify the graft type or side, 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 another limb. Check documentation if the graft type or ulcer relationship is unclear.
Coding tip
Confirm both the right-leg graft location and the ulceration linkage before assigning I70.73.
