The ICD-10 is a medical classification system used for the diagnosis and treatment of various diseases. In this blog, we will focus on the different types of heart failure codes available in the ICD-10.
What are the different types of heart failure codes available in the ICD-10?
Answer: There are several types of heart failure codes available in ICD-10, such as left ventricular failure,
unspecified (I50.1),
Unspecified systolic (congestive) heart failure (I50.20),
Acute systolic (congestive) heart failure (I50.21)
Chronic systolic (congestive) heart failure (I50.22)
Acute or chronic systolic (congestive) heart failure (I50.23)
Diastolic (congestive) heart failure, unspecified (I50.30)

Acute right heart failure (I50.811),
Chronic right heart failure (I50.812),
Acute or chronic right heart failure (I50.813),
right heart failure due to left heart failure (I50.814),
Biventricular heart failure (I50.82),
High output heart failure (I50.83),
End-stage heart failure (I50.84),
and Heart failure, unspecified (I50.89).
What is the importance of proper heart failure coding in ICD-10?
Answer: Proper coding of heart failure in ICD-10 is essential for accurate diagnosis, treatment, and reimbursement. It allows healthcare providers to monitor and track the prevalence and incidence of heart failure, which can aid in research, public health planning, and resource allocation. Additionally, proper coding ensures that patients receive the proper care and treatment, which can improve their overall quality of life and reduce healthcare costs.
What are the common causes of heart failure?
Answer: Common causes of heart failure include hypertension, coronary artery disease, heart valve disease, cardiomyopathy, congenital heart disease, and arrhythmias. Other risk factors such as obesity, diabetes, and smoking can also contribute to the development of heart failure.
In conclusion, heart failure is a serious medical condition that can have a significant impact on the lives of patients. Proper coding in ICD-10 is essential for accurate diagnosis, treatment, and follow-up of heart failure. By understanding the different types of heart failure codes available in ICD-10 and the common causes of heart failure, healthcare providers can improve patient care and outcomes. Diastolic and systolic dysfunction are two types of heart failure. Diastolic dysfunction is the underlying cause of ventricular failure and produces the symptoms and signs of heart failure. Systolic dysfunction is associated with left ventricular failure in the presence of marked cardiomegaly. If these conditions are present with hypertension, then they should not be coded further, as they are included in codes I11 and I13.
Heart failure occurs when the heart is unable to pump (systolic) or fill (diastolic) properly due to certain conditions, such as coronary artery disease or high blood pressure. Symptoms include shortness of breath, fatigue, swollen legs, and a rapid heartbeat. However, these symptoms should not be coded.
When coding heart failure, it is important to determine the type. If there is more than one type, all types must be encoded. Acute systolic (congestive) heart failure is not an essential modifier, and acute should be coded before chronic. If one type of heart failure is acute and another type is chronic, such as acute systolic heart failure and chronic diastolic heart failure, code the conditions separately and not as acute on chronic.
Heart failure terms under I50 include diagnostic terms such as systolic (congestive) heart failure, diastolic (congestive) heart failure, and combined systolic and diastolic (congestive) heart failure. End-stage heart failure should also be coded, if applicable.
The staging of heart failure includes stage A, which is the presence of heart failure risk factors but no heart disease or symptoms, and should not be coded as heart failure but as Z91.89. Stage B is where heart disease is present but there are no symptoms, while stage C involves structural heart disease with symptoms. Stage D is end-stage heart failure (I50.84).
here are some example scenarios for each of the ICD-10 codes:
I50.1 Left ventricular failure:
A patient with a history of hypertension and coronary artery disease presents to the emergency department with shortness of breath and fatigue. An echocardiogram shows reduced left ventricular function. The patient is diagnosed with left ventricular failure and is treated with diuretics and ACE inhibitors.
I50.2 Systolic (congestive) heart failure
An elderly patient with a history of myocardial infarction and diabetes mellitus presents to the primary care office with worsening dyspnea and edema. A chest x-ray shows pulmonary congestion, and an echocardiogram reveals a reduced ejection fraction. The patient is diagnosed with systolic heart failure and beta-blockers and diuretics are prescribed.
I50.3 Diastolic (congestive) heart failure
A patient with a history of hypertension and obesity presents with dyspnea on exertion and peripheral edema. An echocardiogram shows a normal ejection fraction but increased left atrial volume and abnormal diastolic function. The patient is diagnosed with diastolic heart failure and treated with diuretics and calcium channel blockers.
I50.4 Combined systolic (congestive) and diastolic (congestive) heart failure:
An elderly patient with a history of hypertension, coronary artery disease, and chronic kidney disease presents to the emergency department with worsening dyspnea, orthopnea, and paroxysmal nocturnal dyspnea. An echocardiogram reveals reduced ejection fraction and increased left atrial volume with abnormal diastolic function. The patient is diagnosed with combined systolic and diastolic heart failure and is treated with diuretics, beta-blockers, and ACE inhibitors.
I50.9 Heart failure, unspecified
A patient with a history of diabetes mellitus and obesity presents to the primary care office with fatigue and shortness of breath. The patient's medical history and physical examination are inconclusive for a specific type of heart failure. The patient is diagnosed with unspecified heart failure and is referred for further testing.
I11.0 Hypertensive heart disease with heart failure:
A patient with a history of poorly controlled hypertension presents to the emergency department with dyspnea and chest pain. An ECG shows evidence of left ventricular hypertrophy, and an echocardiogram reveals reduced ejection fraction. The patient is diagnosed with hypertensive heart disease with heart failure and is treated with diuretics, ACE inhibitors, and beta-blockers.
I11.9 Hypertensive heart disease without heart failure:
A patient with a history of hypertension presents to the primary care clinic for a routine checkup. The patient has no current symptoms of heart failure, but an ECG shows evidence of left ventricular hypertrophy. The patient is diagnosed with hypertensive heart disease without heart failure and is prescribed antihypertensive medication.
I13.0 Hypertensive heart and CKD with heart failure and CKD stage 1-stage 4, or CKD unspecified:
A patient with a history of poorly controlled hypertension and stage 3 chronic kidney disease presents to the emergency department with dyspnea and edema. An echocardiogram shows a reduced ejection fraction, and the patient is diagnosed with a hypertensive heart and CKD with heart failure and stage 3 CKD. The patient is treated with diuretics, ACE inhibitors, and referred to a nephrologist.
I13.10 Hypertensive heart and CKD without heart failure, with stage 1 - stage 4 CKD or CKD unspecified:
A patient with a history of hypertension and stage 2 chronic kidney disease presents to the primary care office for routine monitoring.
Here are some code scenarios with ejection fraction included. The ejection fraction is only assumed to not be 100 percent correct.
Combined systolic (congestive) and diastolic (congestive) chronic heart failure (I50.42) with an ejection fraction of 40%. This could be a patient with a history of heart disease and ongoing symptoms of heart failure, with a documented ejection fraction indicating that both the heart's ability to pump blood (systolic function) and fill with blood (diastolic function) are impaired.
Acute or chronic combined systolic (congestive) and diastolic (congestive) heart failure (I50.43) with an ejection fraction 25%. This could be a patient with a history of heart failure experiencing a sudden worsening of symptoms, with a documented ejection fraction indicating severely impaired systolic and diastolic function.
Unspecified right heart failure (I50.810) with an ejection fraction of 50%. This could be a patient with symptoms of right-sided heart failure, such as swelling in the legs and abdomen, with a documented ejection fraction indicating that the right side of the heart is not working properly.
Acute right heart failure (I50.811) with an ejection fraction of 35%. This could be a patient with a sudden onset of symptoms of right heart failure, such as shortness of breath and fatigue, with a documented ejection fraction indicating impaired right ventricular function.
Chronic right heart failure (I50.812) with an ejection fraction of 45%. This could be a patient with a long history of right heart failure, with a documented ejection fraction indicating continued deterioration of right ventricular function.
Acute on chronic right heart failure (I50.813) with an ejection fraction of 20%. This could be a patient with a history of chronic right heart failure experiencing a sudden worsening of symptoms, with a documented ejection fraction indicating severe impairment of right ventricular function.
Right heart failure due to left heart failure (I50.814) with an ejection fraction 30%. This could be a patient with left-sided heart failure that has progressed to involve the right side of the heart as well, with a documented ejection fraction indicating impaired left and right ventricular function.
Biventricular heart failure (I50.82) with an ejection fraction of 40%. This could be a patient with symptoms of heart failure affecting both the left and right sides of the heart, with a documented ejection fraction indicating impaired function of both ventricles.
High-output heart failure (I50.83) with an ejection fraction of 55%. This could be a patient with a condition that causes abnormally high cardiac output, such as severe anemia or hyperthyroidism, with a documented ejection fraction indicating that the heart can pump blood efficiently despite the increased workload.
End-stage heart failure (I50.84) with an ejection fraction of 10%. This could be a patient with advanced heart failure who has not responded to treatment, with a documented ejection fraction indicating severely impaired ventricular function and a poor prognosis.
