ICD-10 Code E13.52 – Other specified diabetes mellitus with diabetic peripheral angiopathy with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.52 – Other specified diabetes mellitus with diabetic peripheral angiopathy with gangrene
What it is
This code identifies diabetes mellitus in the “other specified” category with peripheral angiopathy and gangrene. Use it when the diabetes-related vascular disease in the legs or feet has led to tissue death.
Clinical signs
Look for documented diabetes with peripheral circulatory disease plus gangrene, often affecting toes, feet, or lower extremities. Clinical features vary; refer to documentation.
When to use this code
Use E13.52 when the record clearly links the patient’s gangrene to diabetic peripheral angiopathy and the diabetes is not type 1 or type 2. It may appear in notes describing diabetic foot ischemia, necrosis, or dry gangrene with peripheral vascular involvement. Check documentation for the diabetes type and site.
Do not use for
Do not use this code for gangrene without a documented diabetic vascular cause, or for diabetic foot ulcers without gangrene. Do not assume it applies when the diabetes type is unspecified.
Coding tip
Assign the diabetes type and the gangrene code only when the provider explicitly documents the diabetic peripheral angiopathy with gangrene relationship.
