ICD-10 Code E13.2 – Other specified diabetes mellitus with kidney complications (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.2 – Other specified diabetes mellitus with kidney complications
What it is
This code identifies diabetes mellitus from another specified cause, with kidney involvement. Use it when the record documents diabetes and a renal complication, but the diabetes type does not fit the usual categories.
Clinical signs
Clinical features vary; refer to documentation. Kidney complications may include diabetic kidney disease, proteinuria, or chronic renal impairment noted by the clinician.
When to use this code
Use E13.2 when the provider links a specified diabetes diagnosis to a kidney complication in the chart. It is appropriate when the diabetes is not type 1, type 2, or gestational, and the renal condition is clearly documented as related.
Code the documented renal complication as directed by the record and sequencing rules. If the note does not clearly connect the diabetes and kidney condition, check documentation before assigning this code.
Do not use for
Do not use this code for type 1 or type 2 diabetes with kidney complications. Do not use it when kidney disease is present but the diabetes-cause relationship is not documented.
Coding tip
Confirm both the diabetes category and the kidney complication are explicitly documented before coding E13.2.
