ICD-10 Code I70.791 – Other atherosclerosis of other type of bypass graft(s) of the extremities, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.791 – Other atherosclerosis of other type of bypass graft(s) of the extremities, right leg
What it is
This code identifies atherosclerotic narrowing or blockage affecting a bypass graft in the right leg. It applies when the graft is not a vein or synthetic graft category specified elsewhere.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include reduced leg blood flow, exertional pain, rest pain, coolness, or diminished pulses when the graft is compromised.
When to use this code
Use this code when the record documents atherosclerosis involving an other-type bypass graft in the right lower extremity. The provider should identify the right leg site and the graft type as not otherwise classified. Check documentation if the graft material or laterality is unclear.
Do not use for
Do not use this code for native artery atherosclerosis without graft involvement. Also avoid it when the graft is in another extremity, the left leg, or when a more specific bypass-graft code is documented.
Coding tip
Verify both laterality and graft type in the operative or vascular note before assigning I70.791.
