ICD-10 Code E10.3 – Type 1 diabetes mellitus with ophthalmic complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.3 – Type 1 diabetes mellitus with ophthalmic complications
What it is
This code identifies type 1 diabetes with eye-related complications. Use it when the record links diabetic eye disease to type 1 diabetes, such as retinopathy or other ophthalmic involvement.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include diabetic retinopathy, visual disturbance, or other documented eye complications associated with diabetes.
When to use this code
Use E10.3 when the provider documents type 1 diabetes and an ophthalmic complication in the same encounter. The eye condition must be described as diabetic or clearly linked to diabetes. If the record is nonspecific, check documentation before coding.
Do not use for
Do not use this code for type 2 diabetes, gestational diabetes, or eye disease without a documented diabetic link. If the ophthalmic problem is unrelated to diabetes, code the eye condition instead.
Coding tip
Verify the exact eye complication in the note, because E10.3 requires a documented diabetic ophthalmic manifestation.
