ICD-10 Code E11.3 – Type 2 diabetes mellitus with ophthalmic complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.3 – Type 2 diabetes mellitus with ophthalmic complications
What it is
This code identifies type 2 diabetes mellitus with eye-related complications. Use it when diabetes is documented as affecting the eye, such as diabetic retinopathy or other ophthalmic involvement.
Clinical signs
Clinical features vary; refer to documentation. Common findings may include diabetic retinal changes, visual disturbance, or ophthalmology notes describing diabetes-related eye disease.
When to use this code
Use E11.3 when the provider links type 2 diabetes to an ophthalmic complication in the assessment or problem list. It is appropriate for encounters focused on diabetic eye disease, including follow-up visits and specialist evaluations. Confirm the specific eye condition is documented if you need a more detailed code.
Do not use for
Do not use this code for type 2 diabetes without eye involvement. Also avoid it when the record describes a non-diabetic eye disorder or when documentation does not clearly connect the eye finding to diabetes.
Coding tip
Check the ophthalmology note for the exact diabetic eye diagnosis, because E11.3 is a category code and may require a more specific fourth or fifth character.
