ICD 10 For Atrial Fibrillation – I48

The ICD 10 is a code used to diagnose and describe diseases. The ICD 10 for Atrial Fibrillation (AFib) is a code given to people who have this heart condition. Atrial fibrillation is a heart condition that can cause symptoms like heart palpitations, shortness of breath, and chest pain.

While it’s not usually life-threatening, it can be serious and even lead to stroke. If you have atrial fibrillation, your doctor will likely give you a specific ICD 10 code for it. This code will be used to track your diagnosis, treatment, and progress.

What is ICD 10?

The International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) is a system used by physicians and other healthcare providers to classify and code all diagnoses, symptoms and procedures recorded in conjunction with patient care in the United States. The ICD-10-CM is based on the World Health Organization’s ICD-10 and is released every year on October 1st by the Centers for Medicare and Medicaid Services (CMS).

ICD 10 Code For Atrial Fibrillation

The ICD 10 For Atrial Fibrillation is I48.

ICD-10-CM consists of two types of codes:

1) Procedure codes – used to describe medical, surgical or diagnostic procedures performed on patients. These codes are three to seven characters long and are alphanumeric.

2) Diagnosis codes – used to describe signs, symptoms, conditions and illnesses. These codes are three to seven characters long and are numeric.

What is Atrial Fibrillation?

Atrial fibrillation is an irregular heartbeat that can lead to blood clots, strokes, and other heart problems.

When the heart beats, it squeezes blood through the chambers and into the arteries. This is how blood circulates throughout the body. In atrial fibrillation, the heart’s upper chambers (the atria) quiver or twitch instead of contracting normally. This means that blood isn’t moving as efficiently through the heart as it should be.

Blood can pool in the atria and form clots. If a clot breaks off and travels to the brain, it can cause a stroke. Atrial fibrillation is a leading cause of strokes.

People with atrial fibrillation may feel heart palpitations, shortness of breath, or chest pain. But many people with atrial fibrillation don’t have any symptoms. That’s why it’s important to see your doctor for regular checkups, so they can check your heart health and look for signs of atrial fibrillation.

The Different Types of Atrial Fibrillation

There are four main types of atrial fibrillation: paroxysmal, persistent, permanent, and lone atrial fibrillation.

Paroxysmal atrial fibrillation is the most common type, and it usually starts and ends suddenly. It may happen sporadically or in short bursts lasting for a few minutes to a few hours. Some people with this type of atrial fibrillation may not even realize they have it because the episodes are so brief.

Persistent atrial fibrillation is less common than paroxysmal atrial fibrillation. It typically lasts for more than seven days but less than one year. People with persistent atrial fibrillation may have symptoms that come and go, or they may have symptoms all the time.

Permanent atrial fibrillation is the least common type. It occurs when episodes of atrial fibrillation last for more than one year. This type is also known as chronic atrial fibrillation. People with permanent atrial fibrillation often have symptom that are constant and may get worse over time.

Lone atrial fibrillation is a rare form of the condition that usually affects young, healthy people who have no other heart problems.

Causes of Atrial Fibrillation

Atrial fibrillation (A-fib) is the most common type of heart arrhythmia, or irregular heartbeat. A-fib occurs when the electrical signals that control your heart’s pumping action become out of sync, causing the atria (upper chambers of the heart) to beat erratically and faster than normal. This can lead to blood pooling in the atria and an increased risk for clot formation.

There are many factors that can contribute to A-fib, including:

• High blood pressure
• Coronary artery disease
• Sleep apnea
• Excessive alcohol consumption
• Thyroid problems
• Stress
• Other heart conditions such as mitral valve prolapse

Symptoms of Atrial Fibrillation

Atrial fibrillation (AF) is the most common type of irregular heartbeat. An irregular heartbeat means that the heart is beating too fast, too slow, or with an irregular rhythm. AF can cause symptoms like:

-Heart palpitations (a sensation that your heart is pounding or racing)
-Shortness of breath
-Chest pain or discomfort
-Dizziness or lightheadedness

If you have any of these symptoms, it’s important to see a doctor right away. While AF itself isn’t usually life-threatening, it can lead to other serious problems like stroke.

Diagnosis of Atrial Fibrillation

The first step in diagnosing atrial fibrillation is to obtain a thorough medical history from the patient. This will help the doctor to rule out other potential causes of the symptoms. A physical examination will also be conducted. The doctor may order tests, such as an electrocardiogram (ECG) or echocardiogram, to confirm the diagnosis.

Once atrial fibrillation has been diagnosed, the doctor will work with the patient to determine the best course of treatment. This may involve medications, electrical cardioversion, or surgery.

Treatment of Atrial Fibrillation

There are a variety of treatments available for atrial fibrillation (AFib), and the best treatment option for you will depend on your individual circumstances. Some common treatments include:

-Antiarrhythmic medications: These drugs can help to control your heart rate and rhythm.

-Catheter ablation: This procedure uses heat or cold energy to destroy the abnormal tissue in your heart that is causing AFib.

-Cardioversion: This procedure uses electrical shocks to convert your heart back to its normal rhythm.

-Implantable cardioverter defibrillator (ICD): This device is implanted under your skin and monitors your heart for abnormal rhythms. If an abnormal rhythm is detected, the ICD will deliver a shock to your heart to restore a normal rhythm.

Prevention of Atrial Fibrillation

The best way to prevent atrial fibrillation is to manage any underlying conditions that may be contributing to your risk. This may include managing high blood pressure, heart disease, diabetes, or thyroid problems. If you have had a previous heart attack or stroke, your doctor may also recommend taking blood thinners to help prevent another event. In some cases, lifestyle changes such as eating a healthy diet, exercising regularly, and avoiding alcohol and caffeine may also help reduce your risk of atrial fibrillation.


If you have been diagnosed with atrial fibrillation, your doctor will likely use the ICD 10 code to categorize and track your condition. The ICD 10 is a comprehensive system used by medical professionals to diagnose and treat diseases, and it can be incredibly helpful in providing information about your treatment options and prognosis. If you have any questions about your diagnosis or treatment, be sure to ask your doctor for more information on the ICD 10 and how it applies to your individual case.
