ICD-10 Code E09.33 – Drug or chemical induced diabetes mellitus with moderate nonproliferative diabetic retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.33 – Drug or chemical induced diabetes mellitus with moderate nonproliferative diabetic retinopathy
What it is
This code identifies diabetes caused by a drug or chemical, along with moderate nonproliferative diabetic retinopathy. Use it when the record links the diabetes to an external substance and documents this retinal complication.
Clinical signs
Findings usually reflect diabetic retinopathy with retinal microvascular damage, such as hemorrhages, microaneurysms, or other nonproliferative changes. Clinical features vary; refer to documentation.
When to use this code
Use E09.33 when the provider documents drug- or chemical-induced diabetes and specifically states moderate nonproliferative diabetic retinopathy. The causal agent should be identified or clearly implied in the chart. Check documentation if the retinopathy grade is not explicit.
Do not use for
Do not use this code for diabetes not caused by a drug or chemical, or when retinopathy is absent or coded to a different severity. Check documentation if the eye finding is unspecified.
Coding tip
Assign the code only when both the drug-induced diabetes and the moderate nonproliferative retinopathy are documented together.
