2022 ICD-10-CM Code I48

Atrial fibrillation and flutter

Version 2021

Not Valid for Submission

ICD-10:I48
Short Description:Atrial fibrillation and flutter
Long Description:Atrial fibrillation and flutter

Code Classification

  • Diseases of the circulatory system (I00–I99)
    • Other forms of heart disease (I30-I5A)
      • Atrial fibrillation and flutter (I48)

I48 is a non-specific and non-billable diagnosis code code, consider using a code with a higher level of specificity for a diagnosis of atrial fibrillation and flutter. The code is not specific and is NOT valid for the year 2022 for the submission of HIPAA-covered transactions. Category or Header define the heading of a category of codes that may be further subdivided by the use of 4th, 5th, 6th or 7th characters.

Specific Coding for Atrial fibrillation and flutter

Non-specific codes like I48 require more digits to indicate the appropriate level of specificity. Consider using any of the following ICD-10 codes with a higher level of specificity when coding for atrial fibrillation and flutter:

  • BILLABLE CODE - Use I48.0 for Paroxysmal atrial fibrillation
  • NON-BILLABLE CODE - I48.1 for Persistent atrial fibrillation
  • BILLABLE CODE - Use I48.11 for Longstanding persistent atrial fibrillation
  • BILLABLE CODE - Use I48.19 for Other persistent atrial fibrillation
  • NON-BILLABLE CODE - I48.2 for Chronic atrial fibrillation
  • BILLABLE CODE - Use I48.20 for Chronic atrial fibrillation, unspecified
  • BILLABLE CODE - Use I48.21 for Permanent atrial fibrillation
  • BILLABLE CODE - Use I48.3 for Typical atrial flutter
  • BILLABLE CODE - Use I48.4 for Atypical atrial flutter
  • NON-BILLABLE CODE - I48.9 for Unspecified atrial fibrillation and atrial flutter
  • BILLABLE CODE - Use I48.91 for Unspecified atrial fibrillation
  • BILLABLE CODE - Use I48.92 for Unspecified atrial flutter

Information for Patients


Arrhythmia

An arrhythmia is a problem with the rate or rhythm of your heartbeat. It means that your heart beats too quickly, too slowly, or with an irregular pattern. When the heart beats faster than normal, it is called tachycardia. When the heart beats too slowly, it is called bradycardia. The most common type of arrhythmia is atrial fibrillation, which causes an irregular and fast heart beat.

Many factors can affect your heart's rhythm, such as having had a heart attack, smoking, congenital heart defects, and stress. Some substances or medicines may also cause arrhythmias.

Symptoms of arrhythmias include

Your doctor can run tests to find out if you have an arrhythmia. Treatment to restore a normal heart rhythm may include medicines, an implantable cardioverter-defibrillator (ICD) or pacemaker, or sometimes surgery.

Atrial Fibrillation

An arrhythmia is a problem with the speed or rhythm of the heartbeat. Atrial fibrillation (AF) is the most common type of arrhythmia. The cause is a disorder in the heart's electrical system.

Often, people who have AF may not even feel symptoms. But you may feel

AF can lead to an increased risk of stroke. In many patients, it can also cause chest pain, heart attack, or heart failure.

Doctors diagnose AF using family and medical history, a physical exam, and a test called an electrocardiogram (EKG), which looks at the electrical waves your heart makes. Treatments include medicines and procedures to restore normal rhythm.

Familial atrial fibrillation

Familial atrial fibrillation is an inherited abnormality of the heart's normal rhythm. Atrial fibrillation is characterized by episodes of uncoordinated electrical activity (fibrillation) in the heart's upper chambers (the atria), which cause a fast and irregular heartbeat. If untreated, this abnormal heart rhythm (arrhythmia) can lead to dizziness, chest pain, a sensation of fluttering or pounding in the chest (palpitations), shortness of breath, or fainting (syncope). Atrial fibrillation also increases the risk of stroke and sudden death. Complications of atrial fibrillation can occur at any age, although some people with this heart condition never experience any health problems associated with the disorder.
