ICD-10 Code E09.32 – Drug or chemical induced diabetes mellitus with mild nonproliferative diabetic retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.32 – Drug or chemical induced diabetes mellitus with mild nonproliferative diabetic retinopathy
What it is
This code identifies diabetes caused by a drug or chemical, along with mild nonproliferative diabetic retinopathy in the eye. Use it when documentation links the diabetes to an external substance and notes this retinopathy stage.
Clinical signs
Clinical features vary; refer to documentation. Mild nonproliferative diabetic retinopathy generally means early retinal vascular changes without proliferative disease, and the record should support both the diabetes type and the eye complication.
When to use this code
Use E09.32 when the provider documents drug- or chemical-induced diabetes and specifies mild nonproliferative diabetic retinopathy. It is appropriate for encounters focused on diabetic eye disease when the causal substance and retinopathy severity are both recorded. Check documentation if the cause or eye finding is unclear.
Do not use for
Do not use this code if diabetes is not documented as drug or chemical induced, or if the retinopathy type is different. Do not assign it when the eye complication is absent or not specified.
Coding tip
Verify the causal agent and the exact retinopathy severity in the note before assigning E09.32.
