ICD-10 Code E10.39 – Type 1 diabetes mellitus with other diabetic ophthalmic complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.39 – Type 1 diabetes mellitus with other diabetic ophthalmic complication
What it is
This code identifies type 1 diabetes with an eye complication that is not named by a more specific diabetic ophthalmic code. Use it when documentation confirms a diabetic eye disorder linked to type 1 diabetes.
Clinical signs
Clinical features vary; refer to documentation. The record may describe diabetic eye disease, visual disturbance, or an ophthalmic complication attributed to diabetes, but the exact eye condition should be specified when available.
When to use this code
Use E10.39 when the provider documents type 1 diabetes and a diabetic ophthalmic complication, but the eye condition does not fit a more specific code. It is appropriate when the note clearly links the eye disorder to diabetes. If the documentation names a specific retinal or other eye complication, select the more precise code instead.
Do not use for
Do not use this code for type 2 diabetes, unspecified diabetes, or eye disease without a documented diabetic link. Check documentation if the ophthalmic complication is more specifically identified.
Coding tip
Code the diabetes and the eye complication only as documented, and query for specificity when the ophthalmic diagnosis is vague.
