ICD-10 Code E08.351 – Diabetes mellitus due to underlying condition with proliferative diabetic retinopathy with macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.351 – Diabetes mellitus due to underlying condition with proliferative diabetic retinopathy with macular edema
What it is
This code identifies diabetes caused by another underlying condition, with eye damage showing proliferative diabetic retinopathy and macular edema. Use it when the record links the diabetes to a secondary cause and documents both retinal proliferation and macular swelling.
Clinical signs
Clinical features vary; refer to documentation. Typical findings include diabetic retinal neovascularization and evidence of macular edema on eye examination or imaging, with vision changes possible.
When to use this code
Use this code when the provider documents diabetes mellitus due to an underlying condition and specifically identifies proliferative diabetic retinopathy with macular edema. The eye condition must be tied to the diabetic disease process in the chart. If the cause of diabetes or the retinal stage is unclear, check documentation before coding.
Do not use for
Do not use this code for diabetes not caused by another condition, or for diabetic retinopathy without proliferative changes or macular edema. Check documentation if the eye findings are unspecified.
Coding tip
Verify both the secondary diabetes etiology and the exact retinopathy stage before assigning E08.351.
