ICD-10 Code I70.92 – Chronic total occlusion of artery of the extremities (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I70.92 – Chronic total occlusion of artery of the extremities
What it is
This code identifies a chronic, complete blockage of an artery supplying an arm or leg. It means blood flow is persistently obstructed in an extremity artery, usually from long-standing peripheral arterial disease.
Clinical signs
Clinical features vary; refer to documentation. Common findings include diminished pulses, limb pain with exertion, rest pain, or poor wound healing in the affected extremity. Imaging or vascular studies may confirm the occlusion.
When to use this code
Use I70.92 when the record clearly documents a chronic total occlusion in an artery of the extremities. It is appropriate when the provider identifies the condition as chronic and complete, not merely stenosis or general atherosclerosis. Check documentation for the specific vessel and laterality if available.
Do not use for
Do not use this code for acute arterial occlusion, embolism, or nonspecific peripheral vascular disease. If the record only says “arterial disease” without a chronic total occlusion, check documentation.
Coding tip
Assign this code only when the provider explicitly documents chronic total occlusion; do not infer it from imaging alone.
