ICD-10 Code E08.32 – Diabetes mellitus due to underlying condition with mild nonproliferative diabetic retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.32 – Diabetes mellitus due to underlying condition with mild nonproliferative diabetic retinopathy
What it is
This code identifies diabetes caused by another underlying condition, along with mild nonproliferative diabetic retinopathy. Use it when the record links the diabetes to a secondary cause and documents this eye complication.
Clinical signs
Clinical features vary; refer to documentation. Mild nonproliferative diabetic retinopathy is usually documented by retinal microaneurysms and small hemorrhages, without proliferative changes.
When to use this code
Use this code when the provider states diabetes is due to an underlying condition and also documents mild nonproliferative diabetic retinopathy. The record should clearly connect both diagnoses. If the retinopathy severity or diabetes etiology is unclear, check documentation before coding.
Do not use for
Do not use this code for diabetes not caused by another condition, or for retinopathy without a documented diabetic relationship. Check documentation if the eye findings are more severe or the diagnosis is unspecified.
Coding tip
Verify that the underlying cause of diabetes and the retinopathy severity are both documented before assigning E08.32.
