ICD-10 Code I70.293 – Other atherosclerosis of native arteries of extremities, bilateral legs (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.293 – Other atherosclerosis of native arteries of extremities, bilateral legs
What it is
This code identifies atherosclerosis in the native arteries of both lower extremities when the documentation does not specify a more exact subtype. It refers to plaque-related narrowing or hardening affecting the legs.
Clinical signs
Common findings include leg pain with walking, diminished pulses, cool skin, or other signs of poor blood flow. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents other atherosclerosis involving native arteries in both legs and does not name a more specific peripheral arterial disease code. You should confirm bilateral involvement and that the condition affects native, not bypassed or grafted, vessels. Check documentation if laterality is unclear.
Do not use for
Do not use it for atherosclerosis limited to one leg, unspecified laterality, or disease of bypass grafts or other non-native vessels. Check documentation for a more specific code when the record identifies the exact artery or complication.
Coding tip
Verify bilateral leg involvement in the assessment, problem list, or vascular study before assigning I70.293.
