ICD-10 Code E13.32 – Other specified diabetes mellitus with mild nonproliferative diabetic retinopathy (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.32 – Other specified diabetes mellitus with mild nonproliferative diabetic retinopathy
What it is
This code identifies diabetes mellitus classified as “other specified,” together with mild nonproliferative diabetic retinopathy. It signals early diabetic retinal damage without proliferative changes.
Clinical signs
Clinical features vary; refer to documentation. Mild nonproliferative diabetic retinopathy may be documented by retinal microaneurysms or small retinal hemorrhages, with no evidence of proliferative disease.
When to use this code
Use this code when the provider documents diabetes in the “other specified” category and also documents mild nonproliferative diabetic retinopathy. Apply it when the eye finding is linked to the diabetes in the record. If the type of diabetes or retinopathy severity is unclear, check documentation before assigning the code.
Do not use for
Do not use this code for diabetes without retinopathy, or when the retinopathy is not documented as mild nonproliferative. Do not assume this code if the diabetes type is unspecified or a different diabetic complication is recorded.
Coding tip
Verify both the diabetes category and the exact retinopathy severity in the provider note before coding.
