ICD-10 Code E11.52 – Type 2 diabetes mellitus with diabetic peripheral angiopathy with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.52 – Type 2 diabetes mellitus with diabetic peripheral angiopathy with gangrene
What it is
This code identifies type 2 diabetes with peripheral blood vessel disease in the limbs, complicated by gangrene. Use it when diabetes is documented as the cause of poor circulation and tissue death in an extremity.
Clinical signs
Typical findings include ischemic skin changes, diminished pulses, pain or numbness in the affected limb, and black or dead tissue consistent with gangrene. Clinical features vary; refer to documentation.
When to use this code
Use E11.52 when the record clearly links type 2 diabetes to peripheral angiopathy and gangrene. The provider should document both the diabetic vascular complication and the gangrenous tissue involvement. If the chart only states diabetes with poor circulation, check documentation before coding.
Do not use for
Do not use this code for gangrene without documented diabetes-related peripheral angiopathy, or for diabetic foot ulcers alone. If the diabetes type or the vascular complication is unclear, check documentation.
Coding tip
Look for provider wording that connects diabetes, peripheral angiopathy, and gangrene in the same diagnosis statement.
