ICD-10 Code E09.3 – Drug or chemical induced diabetes mellitus with ophthalmic complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.3 – Drug or chemical induced diabetes mellitus with ophthalmic complications
What it is
This code identifies diabetes caused by a drug or chemical, with eye-related complications. Use it when documentation links the diabetes to an external substance and notes an ophthalmic condition.
Clinical signs
Clinical features vary; refer to documentation. Eye findings may include diabetic eye disease or other ophthalmic complications recorded by the clinician, along with evidence that the diabetes is medication- or chemical-induced.
When to use this code
Use E09.3 when the provider documents drug- or chemical-induced diabetes mellitus and specifies an ophthalmic complication. This is appropriate when the eye condition is clearly associated with the diabetes. If the cause or complication is not stated, check documentation before assigning the code.
Do not use for
Do not use this code for diabetes that is not caused by a drug or chemical. Also avoid it when the record does not identify an ophthalmic complication or when another diabetes category is documented.
Coding tip
Verify both elements in the note: the external cause of diabetes and the eye complication, before coding E09.3.
