ICD-10 Code I12.0 – Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end stage renal disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I12.0 – Hypertensive chronic kidney disease with stage 5 chronic kidney disease or end stage renal disease
What it is
This code identifies chronic kidney disease caused by hypertension when kidney disease has reached stage 5 or end-stage renal disease. Use it when the record links the renal disease to hypertension.
Clinical signs
Clinical features vary; refer to documentation. You may see longstanding hypertension with advanced kidney failure, and the chart should clearly state stage 5 CKD or end-stage renal disease.
When to use this code
Use I12.0 when the provider documents hypertensive chronic kidney disease with stage 5 CKD or ESRD. It applies whether the patient is pre-dialysis or receiving renal replacement therapy, if the hypertension-CKD relationship is stated.
Code the associated CKD stage separately when instructed by ICD-10-CM guidelines. If the record does not clearly link hypertension and kidney disease, check documentation before assigning this code.
Do not use for
Do not use this code for hypertension without kidney involvement, or for CKD not documented as hypertensive. If the stage is not 5 or ESRD, choose the more specific hypertensive CKD code.
Coding tip
Always verify the provider’s wording for both the hypertensive cause and the CKD stage before coding.
