ICD-10 Code E09.34 – Drug or chemical induced diabetes mellitus with severe nonproliferative diabetic retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.34 – Drug or chemical induced diabetes mellitus with severe nonproliferative diabetic retinopathy
What it is
This code identifies diabetes caused by a drug or chemical, with severe nonproliferative diabetic retinopathy affecting the eyes. Use it when the diabetes and retinal complication are both documented and linked to the same condition.
Clinical signs
Clinical features vary; refer to documentation. Severe nonproliferative diabetic retinopathy is typically documented by an eye specialist and may include retinal hemorrhages, venous changes, or other advanced retinal findings without proliferative disease.
When to use this code
Use this code when the record states diabetes is drug- or chemical-induced and also documents severe nonproliferative diabetic retinopathy. Confirm that the provider links the eye complication to the diabetes, not to another cause. Check documentation if the medication or chemical trigger is not specified.
Do not use for
Do not use this code for diabetes without a documented drug or chemical cause, or for milder retinopathy. Do not use it when proliferative retinopathy or other ocular complications are documented instead.
Coding tip
Verify both the diabetes cause and the exact retinopathy severity before assigning E09.34.
