ICD-10 Code E13.3 – Other specified diabetes mellitus with ophthalmic complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.3 – Other specified diabetes mellitus with ophthalmic complications
What it is
This code identifies diabetes mellitus from another specified cause that has eye-related complications. Use it when the record links the diabetes to an ophthalmic condition, but the diabetes type is not one of the standard categories.
Clinical signs
Clinical features vary; refer to documentation. Eye findings may include diabetic retinopathy, macular edema, cataract, or other ophthalmic complications documented as related to diabetes.
When to use this code
Use E13.3 when the provider documents a specified nonstandard diabetes and an associated eye complication. The ophthalmic condition should be clearly tied to the diabetes in the note. If the record does not specify the diabetes type or the eye complication, check documentation before coding.
Do not use for
Do not use this code for type 1, type 2, or gestational diabetes with eye complications. Also avoid it when the eye disorder is present but not documented as diabetic or diabetes-related.
Coding tip
Confirm both the diabetes category and the eye complication in the provider documentation before assigning E13.3.
