ICD-10 Code E08.52 – Diabetes mellitus due to underlying condition with diabetic peripheral angiopathy with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.52 – Diabetes mellitus due to underlying condition with diabetic peripheral angiopathy with gangrene
What it is
This code identifies diabetes caused by another underlying condition, complicated by peripheral angiopathy and gangrene. Use it when the record links the diabetes to poor blood flow in the extremities with tissue death.
Clinical signs
Typical findings include peripheral vascular disease in a patient with diabetes and documented gangrene of a foot, toe, or other extremity. Clinical features vary; refer to documentation.
When to use this code
Use this code when the provider documents diabetes due to an underlying condition and specifically states diabetic peripheral angiopathy with gangrene. It is appropriate when gangrene is part of the diabetic complication, not a separate unrelated problem. Check documentation if the causal relationship is unclear.
Do not use for
Do not use it for diabetes without gangrene, or for peripheral angiopathy not linked to diabetes due to an underlying condition. Do not assign it when the record does not support the diabetic complication.
Coding tip
Confirm both the underlying-condition diabetes and the gangrene documentation before coding E08.52.
