ICD-10 Code E13.29 – Other specified diabetes mellitus with other diabetic kidney complication (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.29 – Other specified diabetes mellitus with other diabetic kidney complication
What it is
This code identifies diabetes mellitus due to another specified cause, with a kidney complication that does not fit a more specific diabetic kidney code. Use it when documentation clearly supports both the diabetes type and a renal complication.
Clinical signs
Clinical features vary; refer to documentation. Commonly, records may note kidney involvement such as diabetic nephropathy, proteinuria, or chronic kidney disease linked to diabetes.
When to use this code
Use E13.29 when the provider documents other specified diabetes mellitus and a diabetic kidney complication, but the chart does not support a more specific code. It may apply when diabetes is secondary to another condition and renal disease is attributed to that diabetes. Check documentation for the exact kidney manifestation.
Do not use for
Do not use this code if the kidney condition is not documented as diabetic or if a more specific diabetic renal code is available. Do not assume diabetic nephropathy without provider support.
Coding tip
Sequence the diabetes and kidney complication exactly as documented, and query if the renal diagnosis is unclear.
