ICD-10 Code E10.29 – Type 1 diabetes mellitus with other diabetic kidney complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.29 – Type 1 diabetes mellitus with other diabetic kidney complication
What it is
This code identifies type 1 diabetes mellitus with a kidney complication not otherwise specified by a more exact diabetic kidney code. Use it when the record links the renal problem to diabetes, but the documentation does not name diabetic nephropathy or another specific renal manifestation.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of diabetic kidney involvement such as persistent proteinuria, reduced kidney function, or other renal findings attributed to diabetes by the treating clinician.
When to use this code
Use E10.29 when the provider documents type 1 diabetes with a diabetic kidney complication and does not specify a more precise code. It can support encounters where the renal condition is clearly described as diabetes-related, but the exact kidney diagnosis is not stated. If the chart names a different diabetic renal manifestation, code that specific condition instead.
Do not use for
Do not use this code for type 2 diabetes, gestational diabetes, or kidney disease that is not documented as diabetic. Do not assign it when the record supports a more specific diabetic kidney code.
Coding tip
Check the provider’s wording carefully; the kidney complication must be linked to type 1 diabetes, not simply present in the same patient.
