ICD-10 Code E10.22 – Type 1 diabetes mellitus with diabetic chronic kidney disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.22 – Type 1 diabetes mellitus with diabetic chronic kidney disease
What it is
E10.22 identifies type 1 diabetes mellitus complicated by chronic kidney disease. Use it when the record links the kidney disease to diabetes, not when CKD has another documented cause.
Clinical signs
Clinical features vary; refer to documentation. Patients may show evidence of chronic kidney impairment, and the chart should support both type 1 diabetes and diabetic kidney involvement.
When to use this code
Use E10.22 when the provider documents type 1 diabetes with diabetic chronic kidney disease, diabetic nephropathy, or similar wording. It is appropriate when CKD is clearly attributed to diabetes. If the stage of CKD is documented, code it separately as instructed.
Do not use for
Do not use this code for type 2 diabetes, gestational diabetes, or CKD not documented as diabetic. Check documentation if the kidney disease cause is unclear.
Coding tip
Look for an explicit diabetes-to-CKD link in the assessment or problem list before assigning E10.22.
