ICD-10 Code I70.722 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.722 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, left leg
What it is
This code identifies atherosclerotic disease affecting a bypass graft in an extremity, specifically the left leg, with rest pain. It indicates reduced blood flow through the graft causing ischemic pain even when the patient is not active.
Clinical signs
Typical findings include ischemic pain at rest in the affected left leg, often worse at night or when the limb is elevated. Clinical features vary; refer to documentation for graft type, laterality, and evidence of peripheral arterial disease.
When to use this code
Use this code when the provider documents atherosclerosis involving an “other” bypass graft in the left lower extremity and specifically states rest pain. You should also confirm that the bypass graft is the source of the arterial disease, not the native vessel. If laterality or rest pain is not documented, check documentation before assigning this code.
Do not use for
Do not use this code for atherosclerosis of native arteries, other bypass graft locations, or right-sided disease. Do not assign it if the record does not clearly document rest pain or the left leg.
Coding tip
Verify both the graft type and laterality in the operative or vascular note before coding.
