ICD-10 Code I13.10 – Hypertensive Heart and Chronic Kidney Disease Without Heart Failure, With Stage 1 Through Stage 4 Chronic Kidney Disease, or Unspecified Chronic Kidney Disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I13.10 – Hypertensive heart and chronic kidney disease without heart failure, with stage 1 through stage 4 chronic kidney disease, or unspecified chronic kidney disease
What it is
This code identifies a patient with both hypertensive heart disease and chronic kidney disease, but no heart failure is documented. It applies when the kidney disease is stage 1 through stage 4, or when the stage is not specified.
Clinical signs
Clinical features vary; refer to documentation. You should expect evidence of chronic kidney disease alongside hypertensive heart disease, with no mention of heart failure in the record.
When to use this code
Use this code when the provider documents hypertensive heart disease and chronic kidney disease together, and specifically states that heart failure is absent. It also fits when CKD is documented as stage 1 to stage 4, or as unspecified. Check documentation if the stage or heart failure status is unclear.
Do not use for
Do not use this code if heart failure is documented, because a different hypertensive heart and kidney disease code applies. Do not use it when chronic kidney disease is absent or when the record does not support both conditions.
Coding tip
Verify both the hypertension-related heart disease and CKD documentation, and confirm that heart failure is explicitly excluded before assigning I13.10.
