ICD-10 Code E08.2 – Diabetes mellitus due to underlying condition with kidney complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.2 – Diabetes mellitus due to underlying condition with kidney complications
What it is
This code identifies diabetes that is caused by another underlying condition and is complicated by kidney involvement. Use it when the record links the diabetes to renal complications, not primary diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of diabetic kidney disease, such as nephropathy or other renal complications, documented by the provider.
When to use this code
Use E08.2 when the provider documents diabetes mellitus due to an underlying condition and specifically states kidney complications. Code the underlying condition as well, when required. Make sure the note clearly connects the diabetes to the renal complication.
Do not use for
Do not use this code for primary diabetes with kidney disease; that usually falls under a different diabetes category. Check documentation if the renal problem is present but not linked to the diabetes.
Coding tip
Verify both the cause of the diabetes and the kidney complication before assigning E08.2.
