When should I use I11.0?

Cardiology visit for patient with documented hypertensive heart disease and reduced EF with symptoms. Hospital admission for acute decompensated heart failure in patient with known hypertensive cardiomyopathy. Heart failure clinic follow-up for patient with HFpEF attributed to longstanding hypertension. Emergency department visit for acute pulmonary edema in hypertensive patient. Primary care documentation of 'CHF due to hypertensive heart disease'. Titration of heart failure medications in patient with hypertensive etiology

ICD-10 Code: I11.0

Hypertensive Heart Disease with Heart Failure

Hypertensive heart disease with heart failure represents cardiac dysfunction (systolic, diastolic, or combined) directly caused by longstanding systemic hypertension, with clinical manifestations of heart failure present during the encounter.

Clinical Information

Hypertensive heart disease with heart failure occurs when chronic elevated blood pressure leads to pathologic cardiac remodeling and eventual pump failure. Prolonged hypertension causes left ventricular hypertrophy (LVH) as an adaptive response to increased afterload. Over time, this compensatory mechanism becomes maladaptive, leading to diastolic dysfunction (impaired relaxation), and eventually systolic dysfunction (reduced contractility). The progression typically follows this sequence: hypertension → LVH → diastolic dysfunction (heart failure with preserved EF, HFpEF) → mixed dysfunction → systolic dysfunction (heart failure with reduced EF, HFrEF). Approximately 75% of patients with heart failure have a history of hypertension, and hypertension is the most common cause of HFpEF. Clinical presentation includes classic heart failure symptoms: dyspnea on exertion, orthopnea, paroxysmal nocturnal dyspnea, peripheral edema, reduced exercise tolerance, and fatigue. Physical exam may reveal S3 or S4 gallop, pulmonary rales, jugular venous distension, and peripheral edema. Diagnosis requires echocardiographic evidence of structural heart disease (LVH, chamber dilation) and/or reduced ejection fraction, plus clinical heart failure symptoms or elevated natriuretic peptides (BNP/NT-proBNP).

Coding Guidelines

1Use I11.0 when patient has both hypertension and heart failure, and provider documents causal relationship
2Must use additional code to identify type of heart failure: I50.x (systolic, diastolic, combined, or unspecified)
3ICD-10-CM assumes causality between hypertension and heart disease when both are documented
4Do not code I10 (essential hypertension) separately—I11.0 includes the hypertension
5If patient also has chronic kidney disease, use I13.0 or I13.2 instead (hypertensive heart and CKD)
6For hypertensive heart disease WITHOUT heart failure, use I11.9 instead

Common Uses

Cardiology visit for patient with documented hypertensive heart disease and reduced EF with symptoms
Hospital admission for acute decompensated heart failure in patient with known hypertensive cardiomyopathy
Heart failure clinic follow-up for patient with HFpEF attributed to longstanding hypertension
Emergency department visit for acute pulmonary edema in hypertensive patient
Primary care documentation of 'CHF due to hypertensive heart disease'
Titration of heart failure medications in patient with hypertensive etiology

Documentation Requirements

Provider must document both hypertension and heart failure with causal link: 'hypertensive heart disease with heart failure,' 'CHF due to HTN'
Specify type of heart failure: systolic (HFrEF), diastolic (HFpEF), combined, or unspecified
Document LVEF from echocardiogram: <40% (HFrEF), ≥50% (HFpEF), 40-49% (borderline)
Include heart failure class: NYHA Class I-IV or ACC/AHA Stage A-D
Document structural heart changes: LVH, left atrial enlargement, chamber dilation
Note absence of chronic kidney disease (if CKD present, use I13.x instead)

Real-World Coding Examples

65-year-old with 20-year history of hypertension presents with progressive dyspnea and leg swelling. Echocardiogram shows EF 32%, severe LVH, dilated left ventricle. BNP 1200. Physician documents: 'Hypertensive heart disease with systolic heart failure, NYHA class III.' Diagnosis: Hypertensive heart disease with heart failure (I11.0), Chronic systolic heart failure (I50.22).

Patient admitted for acute pulmonary edema. History of poorly controlled hypertension. Echocardiogram shows EF 60% with severe concentric LVH and grade 3 diastolic dysfunction. Cardiologist documents: 'Acute diastolic heart failure due to hypertensive heart disease.' Diagnosis: I11.0, I50.31.

Heart failure clinic visit. Patient with known 'hypertensive cardiomyopathy' stable on carvedilol, lisinopril, and furosemide. Recent echo: EF 45%, mild LVH. Assessment: chronic systolic/diastolic heart failure, compensated. Diagnosis: I11.0, I50.42.
