ICD-10 Code E10.2 – Type 1 diabetes mellitus with kidney complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E10.2 – Type 1 diabetes mellitus with kidney complications
What it is
This code identifies type 1 diabetes mellitus when kidney complications are documented. Use it when the record shows diabetes affecting renal function or a diabetic kidney disorder linked to type 1 diabetes.
Clinical signs
Clinical features vary; refer to documentation. You may see evidence of diabetic kidney disease, such as renal impairment or nephropathy, when the provider links the condition to type 1 diabetes.
When to use this code
Use E10.2 when the clinician documents type 1 diabetes with kidney involvement and does not specify a more detailed subcode. It may apply to diabetic nephropathy, diabetic kidney disease, or other renal complications attributed to type 1 diabetes. Check documentation for the exact renal diagnosis and linkage.
Do not use for
Do not use this code for kidney disease without a documented relationship to type 1 diabetes. It is also not correct for type 2 diabetes or for diabetes with only eye, nerve, or other non-renal complications.
Coding tip
Confirm that the provider explicitly connects the kidney condition to type 1 diabetes before assigning E10.2.
