ICD-10 Code E09.52 – Drug or chemical induced diabetes mellitus with diabetic peripheral angiopathy with gangrene (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.52 – Drug or chemical induced diabetes mellitus with diabetic peripheral angiopathy with gangrene
What it is
This code identifies diabetes caused by a drug or chemical, with peripheral blood vessel disease affecting the limbs and resulting in gangrene. Use it when documentation links the diabetes to an external substance and confirms gangrene.
Clinical signs
Findings may include ischemic changes in the feet or toes, poor peripheral circulation, skin discoloration, ulceration, or tissue necrosis. Clinical features vary; refer to documentation.
When to use this code
Use E09.52 when the record states the diabetes is drug or chemical induced and the patient has diabetic peripheral angiopathy with gangrene. You should also ensure the causal substance is documented, such as a medication or chemical exposure. If the gangrene is present but the diabetes type is not specified, check documentation.
Do not use for
Do not use this code for diabetes without gangrene or without peripheral angiopathy. Do not assign it when the diabetes is not documented as drug or chemical induced.
Coding tip
Confirm both the cause of diabetes and the gangrene complication before coding E09.52.
