What is the ICD 10 Code for CHF? A Complete Guide

ICD 10 Code for CHF - ICD10-Coding


Congestive heart failure (CHF) is a severe condition that affects millions of people worldwide. It occurs when the heart cannot pump enough blood to meet the body’s needs, causing fluid to accumulate in the lungs and other tissues. This can lead to various symptoms, such as difficulty breathing, fatigue, swelling, and weight gain.

If you have CHF, you may wonder what the ICD 10 code for CHF is and why it matters. In this article, we will explain what the ICD 10 code for CHF is, how it is used, and what it means for your diagnosis and treatment.


What is the ICD 10 Code for CHF?

The ICD 10 code for CHF is I50. This is a general code that covers all types of heart failure, regardless of the cause or severity. The ICD 10 code for CHF is used to classify and document CHF in medical records and billing systems.

However, the ICD 10 code for CHF can be further specified by adding a fourth or fifth character to indicate the type of heart failure. For example:

I50.2 This indicates systolic heart failure, which means that the heart cannot contract strongly enough to pump blood effectively.
I50.3 This indicates diastolic heart failure, which means that the heart cannot relax properly to fill with blood.
I50.4 Indicates combined systolic and diastolic heart failure, which means that both functions of the heart are impaired.
I50.8 Indicates other types of heart failure, such as high-output heart failure or right-sided heart failure.
I50.9 Indicates unspecified heart failure, which means that the type of heart failure is not known or documented.


Additionally, some codes can be modified by adding a sixth character to indicate whether the heart failure is acute, chronic, or acute chronic. For example:

I50.21 Indicates acute systolic (congestive) heart failure.
I50.22 Indicates chronic systolic (congestive) heart failure.
I50.23 Indicates acute on chronic systolic (congestive) heart failure.

What are the Symptoms of CHF?

The symptoms of CHF can vary depending on the type and severity of heart failure, as well as other factors such as age, gender, and underlying conditions. However, some common symptoms of CHF include:

  • – Shortness of breath, especially when lying down or exerting yourself
  • – Fatigue and weakness
  • – Swelling in the legs, ankles, feet, or abdomen
  • – Coughing or wheezing
  • – Rapid or irregular heartbeat
  • – Weight gain or loss
  • – Loss of appetite or nausea

If you experience any of these symptoms, you should consult your doctor as soon as possible. CHF can worsen over time and lead to serious complications if left untreated.


How is CHF Diagnosed?

CHF is usually diagnosed based on medical history, physical examination, and symptoms. Your doctor may also order some tests to confirm the diagnosis and determine the cause and severity of your heart failure. These tests may include:

– An electrocardiogram (EKG), which measures the electrical activity of your heart and can detect any abnormalities or damage.

– A chest X-ray, which shows the size and shape of your heart and lungs and can reveal any fluid buildup or congestion.

– An echocardiogram, which uses sound waves to create a detailed image of your heart and can measure its function and structure.

– A blood test, which can check for any signs of infection, inflammation, anemia, kidney function, or other conditions that may affect your heart.

– A B-type natriuretic peptide (BNP) test, which measures a hormone that is released by your heart when it is under stress and can indicate how severe your heart failure is.


How is CHF Treated?

There is no cure for CHF, but it can be managed with medication, lifestyle changes, and surgery. The main goals of treatment are to relieve your symptoms, improve your quality of life, prevent further damage to your heart, and reduce your risk of complications.

The treatment for CHF may vary depending on the type and severity of your condition and your overall health and preferences. Some common treatment options include:

Medications that can help control your blood pressure, fluid levels, heart rate, and rhythm. These may include diuretics (water pills), beta-blockers, angiotensin-converting enzyme (ACE) inhibitors, angiotensin receptor blockers (ARBs), aldosterone antagonists (spironolactone), digoxin (Lanoxin), nitrates (nitroglycerin), hydralazine/isosorbide dinitrate (BiDil), sacubitril/valsartan (Entresto), ivabradine (Corlanor), or others.

Lifestyle changes that can help improve your health and well-being. These may include losing weight if you are overweight or obese; eating a low-salt diet; limiting alcohol intake; quitting smoking; exercising regularly; managing stress; getting enough sleep; monitoring your symptoms; weighing yourself daily; following up with your doctor regularly; and taking your medications as prescribed.

Surgery that can help repair or replace a damaged or diseased part of your heart or improve its function. These may include a coronary artery bypass graft (CABG), a valve repair or replacement (TAVR), pacemaker implantation (CRT), an implantable cardioverter-defibrillator (ICD), a ventricular assist device (VAD), a total artificial heart (TAH), or a heart transplant.


How Can I Prevent CHF?

There is no sure way to prevent CHF but there are some things you can do to reduce your risk factors and protect your heart health. These include:

– Controlling high blood pressure

– Controlling cholesterol levels

– Managing diabetes

– Quitting smoking

– Eating a healthy diet rich in fruits, vegetables, whole grains, lean protein, and low-fat dairy products and low in saturated fat, trans fat, sodium, and added sugars

– Exercising regularly for at least 150 minutes per week of moderate-intensity aerobic activity or 75 minutes per week of vigorous-intensity aerobic activity or a combination of both and doing muscle-strengthening exercises at least twice per week for all major muscle groups

– Maintaining a healthy weight by balancing your calorie intake with your physical activity level and avoiding excessive weight gain or loss

– Limiting alcohol intake to no more than one drink per day for women and two drinks per day for men and avoiding binge drinking which can damage your heart muscle and increase your risk of arrhythmias and sudden cardiac death


What are the Complications of CHF?

CHF can lead to serious complications if not treated properly. Some possible complications include:

Heart attack: A sudden blockage of blood flow to a part of the heart muscle that can cause permanent damage or death.

Stroke: A sudden interruption of blood flow to a part of the brain that can cause permanent damage or death.

Sudden cardiac death: A sudden stoppage of the heartbeat that can cause death within minutes without immediate medical attention.

Kidney failure: A loss of kidney function that can cause 

Liver failure: A loss of liver function that can cause 

  • jaundice,
  • bleeding,
  • infection,
  • and other problems.

If you have any signs or symptoms of these complications, such as 

  • severe chest pain,
  • shortness of breath,
  • dizziness,
  • fainting,
  • confusion,
  • weakness,
  • numbness,
  • vision changes,
  • or bleeding,

you should seek emergency medical care immediately.



CHF is a serious condition that requires ongoing medical care and lifestyle changes. It is important to work with your doctor to develop a treatment plan that suits your needs and goals. If you have any questions or concerns about CHF, please talk to your doctor.
