ICD-10 Code I70.723 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, bilateral legs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.723 – Atherosclerosis of other type of bypass graft(s) of the extremities with rest pain, bilateral legs
What it is
This code identifies atherosclerotic narrowing or blockage in other bypass grafts in the leg arteries, with ischemic rest pain affecting both legs. Use it when the graft is the documented site and the pain occurs without activity.
Clinical signs
Typical findings include leg pain at rest, often worse when lying down, and signs of poor limb perfusion such as cool skin or diminished pulses. Clinical features vary; refer to documentation.
When to use this code
Use I70.723 when the record clearly states atherosclerosis involves an other type of bypass graft in the extremities and specifies rest pain in both legs. You should also confirm the bilateral nature in the provider note or vascular report.
Choose this code when the documentation supports chronic ischemic pain at rest rather than exertional claudication. If the graft type, laterality, or symptom detail is unclear, check documentation before coding.
Do not use for
Do not use this code for native artery atherosclerosis, unilateral leg pain, or bypass graft disease without rest pain. Check documentation if the note describes gangrene or another complication instead.
Coding tip
Verify both the graft location and bilateral rest pain in the same encounter note before assigning I70.723.
