ICD-10 Code I70.622 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with rest pain, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.622 – Atherosclerosis of nonbiological bypass graft(s) of the extremities with rest pain, left leg
What it is
This code identifies atherosclerotic narrowing in a nonbiological bypass graft in the left leg, with ischemic pain present at rest. Use it when documentation specifies both the graft type and the left-sided rest pain.
Clinical signs
Typical findings include persistent foot or leg pain at rest, often worse when the limb is elevated and relieved by dependency. Clinical features vary; refer to documentation.
When to use this code
Use I70.622 when the provider documents atherosclerosis affecting a nonbiological bypass graft in the left lower extremity and notes rest pain. The record should clearly support the graft location, laterality, and ischemic rest pain. Check documentation if the graft material or side is unclear.
Do not use for
Do not use this code for native artery atherosclerosis, graft occlusion without atherosclerosis, or unspecified limb laterality. If documentation does not confirm rest pain, choose the more accurate code. Check documentation.
Coding tip
Verify that “nonbiological bypass graft” and “left leg” are both documented before assigning I70.622.
