What ICD-10 Codes Are Used for Atrial Fibrillation?

The categorization of Atrial Fibrillation, an irregular and often rapid heart rate, involves a variety of Atrial Fibrillation ICD codes. Here are some commonly used ones:

  • I48.0 - Paroxysmal atrial fibrillation: This code refers to AF that begins suddenly and ends spontaneously.
  • I48.1 - Persistent atrial fibrillation: This code is used for AF lasting more than seven days.
  • I48.2 - Chronic atrial fibrillation: This code describes continuous and ongoing AF over a long period.
  • I48.91 - Unspecified atrial fibrillation: This is used when the type of AF is not specified in the patient's medical record.

Which Atrial Fibrillation ICD Codes Are Billable?

A brief overview of the billable ICD-10 codes for Atrial Fibrillation are:

  • I48.0 - Yes, this code is billable. It applies to instances of paroxysmal atrial fibrillation.
  • I48.1 - Yes, this code is billable. It pertains to cases of persistent atrial fibrillation.
  • I48.2 - Yes, this code is billable. It is used in cases of chronic atrial fibrillation.
  • I48.91 - Yes, this code is billable. It is used when the atrial fibrillation type is not specified.

Clinical Information

Atrial fibrillation (AF) is the most common irregular heartbeat, causing a rapid and irregular rhythm. Below is some in-depth clinical information:

  • In AF, the heart's two upper chambers (the atria) beat chaotically and irregularly out of coordination with the two lower chambers (the ventricles). This can lead to blood clot formation, stroke, heart failure, and other heart-related complications.
  • Symptoms may include heart palpitations, shortness of breath, and weakness. However, some people diagnosed with atrial fibrillation have no symptoms and are unaware of their condition until it's discovered during a physical examination.
  • Treatment strategies for AF focus on resetting the heart's rhythm and preventing blood clots, which can reduce stroke risk. The best plan for you will depend on the duration of your atrial fibrillation, the severity of your symptoms, and the underlying cause of your atrial fibrillation.

Synonyms Include:

  • AF
  • Afib
  • Paroxysmal Atrial Fibrillation
  • Chronic Atrial Fibrillation
  • Persistent Atrial Fibrillation

Commonly asked questions

What is the leading cause of Atrial Fibrillation?

Numerous factors, such as high blood pressure, heart attack, coronary artery disease, abnormal heart valves, or any form of heart disease, can cause Atrial Fibrillation.

Can Atrial Fibrillation be cured?

While there's no guaranteed cure for AF, current treatments can help control symptoms and manage the condition effectively. This includes medication, medical procedures, and lifestyle changes.

Is Atrial Fibrillation life-threatening?

If not well-managed, Atrial Fibrillation can potentially lead to severe complications like stroke and heart failure. However, with appropriate treatment and lifestyle adjustments, individuals with AF can lead everyday, healthy lives.
