ICD-10 Code I70.291 – Other atherosclerosis of native arteries of extremities, right leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.291 – Other atherosclerosis of native arteries of extremities, right leg
What it is
I70.291 identifies atherosclerosis in the native arteries of the right leg when the documentation specifies another form of atherosclerosis, not a more specific subtype. It reflects plaque-related narrowing or hardening in the leg’s own arteries.
Clinical signs
Typical findings include reduced leg blood flow, diminished pulses, leg pain with walking, or signs of peripheral arterial disease. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents other atherosclerosis affecting native arteries in the right leg and does not name a more specific category. Apply it when the right-sided location is clear in the record. If laterality or vessel type is unclear, check documentation.
Do not use for
Do not use this code for atherosclerosis in bypass grafts, stents, or other non-native vessels. Do not use it when the documentation identifies a more specific atherosclerotic condition.
Coding tip
Confirm that the record supports right leg laterality and native artery involvement before assigning I70.291.
