ICD-10 Code E08.29 – Diabetes mellitus due to underlying condition with other diabetic kidney complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E08.29 – Diabetes mellitus due to underlying condition with other diabetic kidney complication
What it is
This code identifies diabetes caused by another underlying condition, with a kidney complication that is not specifically classified elsewhere. Use it when the record links diabetes to a secondary cause and notes a diabetic renal problem.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of diabetic kidney involvement such as renal impairment, proteinuria, or nephropathy, but the chart should clearly connect the condition to diabetes.
When to use this code
Use E08.29 when the provider documents diabetes due to another condition and specifies an “other” diabetic kidney complication. It is appropriate when the kidney manifestation is documented but does not fit a more specific diabetic renal code. Code the underlying cause first when instructed by the record.
Do not use for
Do not use this code for diabetes without a documented kidney complication, or when the renal condition is not described as diabetic. Check documentation if the cause of diabetes or the kidney manifestation is unclear.
Coding tip
Verify both the secondary cause of diabetes and the renal complication in the note before assigning E08.29.
