ICD-10 Code E10.52 – Type 1 diabetes mellitus with diabetic peripheral angiopathy with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.52 – Type 1 diabetes mellitus with diabetic peripheral angiopathy with gangrene
What it is
This code identifies type 1 diabetes complicated by peripheral vascular disease in the limbs, with gangrene present. Use it when documentation links the gangrene to diabetic peripheral angiopathy.
Clinical signs
Typical findings include poor limb perfusion, ischemic skin changes, and tissue necrosis or gangrene in an extremity. Clinical features vary; refer to documentation.
When to use this code
Use E10.52 when the record states type 1 diabetes and specifically documents diabetic peripheral angiopathy with gangrene. It fits cases where the provider connects the gangrene to diabetic vascular disease, not to trauma or another cause.
If the chart only notes diabetes with peripheral vascular disease, or gangrene without a documented diabetic vascular link, check documentation before assigning this code.
Do not use for
Do not use this code for type 2 diabetes, diabetic foot ulcer without gangrene, or gangrene unrelated to diabetes. Check documentation.
Coding tip
Confirm that both the type 1 diabetes and the peripheral angiopathy with gangrene are clearly documented before coding E10.52.
