ICD-10 Code I70.292 – Other atherosclerosis of native arteries of extremities, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.292 – Other atherosclerosis of native arteries of extremities, left leg
What it is
This code identifies atherosclerosis in the native arteries of the left leg when the condition is not described by a more specific lower-extremity atherosclerosis code. It reflects plaque-related narrowing or blockage in the leg’s own arteries.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include leg pain with walking, diminished pulses, coldness, or other signs of reduced blood flow in the left lower extremity.
When to use this code
Use I70.292 when the provider documents other atherosclerosis affecting the native arteries of the left leg and no more specific code applies. It is appropriate when the record clearly identifies laterality and native-vessel disease. Check documentation if the note only says peripheral arterial disease or generalized atherosclerosis.
Do not use for
Do not use this code for atherosclerosis of bypass grafts, stents, or unspecified limb vessels. If the documentation does not identify the left leg or the native arteries, check documentation.
Coding tip
Always confirm laterality and that the affected vessel is native, not graft or prosthetic, before assigning I70.292.
