ICD-10 Code E09.39 – Drug or chemical induced diabetes mellitus with other diabetic ophthalmic complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E09.39 – Drug or chemical induced diabetes mellitus with other diabetic ophthalmic complication
What it is
This code identifies diabetes caused by a drug or chemical, when the patient also has a diabetic eye complication that is not otherwise specified. Use it when the record links the diabetes and the ophthalmic problem.
Clinical signs
Clinical features vary; refer to documentation. You may see vision changes or an eye disorder described as diabetic and related to medication- or chemical-induced diabetes.
When to use this code
Use E09.39 when the provider documents drug- or chemical-induced diabetes mellitus with an associated diabetic ophthalmic complication, but does not name a more specific eye manifestation. This is appropriate when the eye condition is clearly tied to the secondary diabetes. Check documentation if the cause of diabetes or the ocular finding is unclear.
Do not use for
Do not use this code for primary type 1 or type 2 diabetes, or for eye disease not documented as diabetic. If the ophthalmic complication is specified elsewhere, choose the more exact code.
Coding tip
Verify both the medication or chemical cause and the eye complication are documented before assigning E09.39.
