ICD-10 Code I70.262 – Atherosclerosis of native arteries of extremities with gangrene, left leg (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.262 – Atherosclerosis of native arteries of extremities with gangrene, left leg
What it is
This code identifies hardening and narrowing of the native arteries in the left leg, complicated by gangrene. Use it when the record shows arterial disease causing tissue death in that limb.
Clinical signs
Findings may include ischemic pain, poor pulses, cold skin, or nonhealing wounds in the left leg. Gangrene indicates tissue necrosis; clinical features vary, so refer to documentation.
When to use this code
Use I70.262 when the provider documents atherosclerosis of native arteries in the left lower extremity and specifically notes gangrene. The left-sided location must be clear in the record. If the chart only describes peripheral arterial disease or ischemia without gangrene, check documentation before assigning this code.
Do not use for
Do not use this code for gangrene without documented atherosclerosis, or for disease limited to grafts, bypasses, or unspecified limbs. Check documentation if the side or vessel type is unclear.
Coding tip
Match the laterality and the word “gangrene” exactly as documented before coding I70.262.
