ICD-10 Code E11.2 – Type 2 diabetes mellitus with kidney complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E11.2 – Type 2 diabetes mellitus with kidney complications
What it is
This code identifies type 2 diabetes with kidney involvement. Use it when the record links diabetes to a renal complication, such as diabetic kidney disease or diabetic nephropathy.
Clinical signs
Clinical features vary; refer to documentation. Commonly, the chart shows chronic kidney disease or other renal impairment attributed to diabetes, with provider documentation connecting both conditions.
When to use this code
Use E11.2 when the provider documents type 2 diabetes and a kidney complication in the same encounter. It is appropriate when the renal condition is described as diabetic kidney disease, diabetic nephropathy, or another diabetes-related kidney disorder.
Make sure the record clearly supports the causal link. If the kidney condition is present but not documented as diabetic, check documentation before coding this combination.
Do not use for
Do not use this code for type 1 diabetes, gestational diabetes, or kidney disease without a documented diabetes connection. Check documentation if the renal disorder is unrelated to diabetes.
Coding tip
Confirm that the provider explicitly links the kidney condition to type 2 diabetes before assigning E11.2.
