ICD-10 Code I11.0 – Hypertensive heart disease with heart failure (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code I11.0 – Hypertensive heart disease with heart failure
What it is
This code identifies heart disease caused by long-standing high blood pressure when heart failure is also present. Use it when the record links hypertensive heart disease to heart failure.
Clinical signs
Clinical features may include dyspnea, fatigue, edema, and other findings of heart failure. Documentation should show both hypertensive heart disease and heart failure; clinical features vary, so refer to documentation.
When to use this code
Use I11.0 when the provider documents hypertensive heart disease with heart failure, or clearly states that hypertension has caused the cardiac condition. It is appropriate for inpatient and outpatient records when heart failure is part of the diagnosis. Check documentation for the specific type of heart failure if recorded.
Do not use for
Do not use this code for hypertension without heart involvement or for heart failure not linked to hypertension. If the record does not clearly connect the conditions, check documentation.
Coding tip
Code the hypertensive heart disease first, and add the heart failure code when the documentation supports both conditions.
