ICD-10 Code E13.22 – Other specified diabetes mellitus with diabetic chronic kidney disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code E13.22 – Other specified diabetes mellitus with diabetic chronic kidney disease
What it is
This code identifies diabetes mellitus that does not fit type 1 or type 2 categories, along with chronic kidney disease caused by or linked to the diabetes. Use it when the record clearly connects the diabetes to CKD.
Clinical signs
Clinical features vary; refer to documentation. Typical records may show diabetes plus documented chronic kidney disease, reduced kidney function, or diabetic nephropathy noted by the provider.
When to use this code
Use E13.22 when the provider documents other specified diabetes mellitus and states that chronic kidney disease is due to, associated with, or complicated by the diabetes. Code the CKD stage separately when documented. If the relationship is not stated, check documentation before assigning this code.
Do not use for
Do not use this code for type 1 or type 2 diabetes with CKD, or for CKD unrelated to diabetes. If the chart does not link the conditions, this code is not appropriate.
Coding tip
Always verify both the diabetes type and the documented diabetic kidney relationship before coding E13.22.
