ICD-10 Code I13 – Hypertensive heart and chronic kidney disease (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I13 – Hypertensive heart and chronic kidney disease
What it is
I13 identifies a combined condition where hypertension is associated with both heart disease and chronic kidney disease. Use it when the record links these disorders as part of the same hypertensive disease process.
Clinical signs
Clinical features vary; refer to documentation. Records may describe hypertensive heart disease, chronic kidney disease, and evidence that both are related to long-standing high blood pressure.
When to use this code
Use I13 when the provider documents hypertensive heart disease with chronic kidney disease, or hypertensive chronic kidney disease with heart involvement. You should code the specific type of heart disease and the CKD stage separately when documented.
If the chart does not clearly connect the heart and kidney conditions to hypertension, check documentation before assigning I13. Do not assume the relationship from isolated diagnoses alone.
Do not use for
Do not use I13 for uncomplicated hypertension, isolated heart disease, or CKD without documented hypertensive linkage. Check documentation if the record does not state that hypertension caused or contributed to both conditions.
Coding tip
Always confirm the provider’s wording and add the appropriate heart disease and CKD codes when the documentation supports them.
