Atrial fibrillation (AF) is a heart rhythm disorder that causes the heart to quiver and flutter. It’s a serious condition, and unless it’s treated, it can lead to stroke or death. To help healthcare professionals diagnose and treat AF, the International Classification of Diseases (ICD) 10 code was created in 1990. ICD 10 is a standard for diagnosis and classification of diseases, and it includes the code for AF and flutter. If you or someone you know has AF or flutter, be sure to ask your doctor about the ICD 10 code. Knowing this code can help ensure that the right treatment is available and that you receive the best care possible.

What is Atrial fibrillation and flutter?
Atrial fibrillation is a type of irregular heart rhythm that can be life-threatening. It is caused by an abnormal heart muscle rhythm. Flutter is a type of atrial fibrillation that is characterized by rapid, short contractions of the heart’s upper chambers (ventricles).

The ICD 10 Code For Atrial fibrillation and flutter is I48
I48.0 Paroxysmal atrial fibrillation
I48.1 Persistent atrial fibrillation
I48.2 Chronic atrial fibrillation
I48.3 Typical atrial flutter
Type I atrial flutter
I48.4 Atypical atrial flutter
Type II atrial flutter
I48.9 Atrial fibrillation and atrial flutter, unspecified
Causes of Atrial fibrillation and flutter
Atrial fibrillation (AF) and flutter are two types of irregular heartbeat. AF is caused by electrical disturbances in the heart’s upper chambers, the atria. Flutter is a type of AF that occurs when the heart muscle quivers rather than beats regularly. AF can be fatal if not treated promptly.
There are many things that can cause AF and flutter, but some of the most common include: genetic factors, age, environmental exposures (such as cigarette smoke), high blood pressure, heart disease, and other medical conditions. Some people also develop AF or flutter after taking certain medications, such as antibiotics or anti-inflammatory drugs.
The best way to prevent AF and flutter is to learn your risk factors and get screened for conditions that may lead to them. If you have symptoms suggestive of AF or flutter, see your doctor immediately for an evaluation. Treatment options include medication, surgery, or cardiac catheterization (PCI).

How to diagnose Atrial fibrillation and flutter
- What are the symptoms of Atrial fibrillation and flutter?
The most common symptom of Atrial fibrillation is shortness of breath. Other symptoms may include chest pain, feeling lightheaded, and fatigue. Flutter may cause palpitations (frequent, rapid heartbeats) or syncope (possible loss of consciousness).
- How is Atrial fibrillation diagnosed?
The most accurate way to diagnose Atrial fibrillation is with an electrocardiogram (EKG). However, if an EKG shows only minor irregularities, it may not be sufficient to determine the condition’s severity. A doctor may also perform a cardiac catheterization to examine the heart’s chambers and measure how well they are functioning. If either test indicates a high risk for heart failure, the doctor may recommend further diagnostic testing, such as an echocardiogram or coronary artery bypass graft surgery.
Treatment options for Atrial fibrillation and flutter
Atrial fibrillation and flutter are both heart conditions that can lead to serious health risks. Treatment options for these conditions vary depending on the severity of the condition. If atrial fibrillation is mild, lifestyle changes, such as a healthy diet and regular physical activity, may be enough to control it. However, if atrial fibrillation is more severe or recurring, medications or cardiac surgery may be necessary.
Medications that can be used to treat atrial fibrillation and flutter include beta blockers (such as propranolol), digoxin, flecainide, quinidine, amiodarone and procainamide. These medications work by blocking certain signals in the heart that lead to heart arrhythmias. Some people also benefit from cardioversion (a treatment that uses electrical current to convert an arrhythmia into a normal rhythm).
Cardiac surgery may be necessary if atrial fibrillation or flutter is severe or if it’s recurrent. Surgery may involve replacing one or more parts of the heart with a mechanical device (cardiopulmonary bypass) or using catheter-based techniques to open up narrow blood vessels in the heart and stop the arrhythmias from happening (shock therapy).
Conclusion
If you’ve been diagnosed with atrial fibrillation or flutter, your doctor will likely prescribe you medication to help control the condition. However, if you’d like to try a less-invasive approach, there is also a treatment available called electrical cardioversion. This involves using an electric current to shock the heart into a normal rhythm. If you’re interested in learning more about this treatment and whether it might be right for you, please consult with your doctor.
