ICD-10 Code E08.319 – Diabetes mellitus due to underlying condition with unspecified diabetic retinopathy without macular edema (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.319 – Diabetes mellitus due to underlying condition with unspecified diabetic retinopathy without macular edema
What it is
This code identifies diabetes caused by another underlying condition, with diabetic retinopathy present but no macular edema specified. Use it when the record links the diabetes to a secondary cause and documents retinopathy.
Clinical signs
Findings usually include retinal changes consistent with diabetic retinopathy, such as microvascular damage seen on eye examination. Clinical features vary; refer to documentation.
When to use this code
Use E08.319 when the provider documents diabetes due to an underlying condition and also notes unspecified diabetic retinopathy without macular edema. The diagnosis should clearly connect the diabetes to the underlying condition. If the record does not specify the retinopathy type or edema status, check documentation.
Do not use for
Do not use this code for diabetes not caused by another condition, or when macular edema is documented. Also avoid it if retinopathy is absent or the chart does not support the underlying-condition relationship.
Coding tip
Confirm both the secondary diabetes cause and the exact eye complication before assigning E08.319.
