Code Classification

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

I48.92 is a billable diagnosis code used to specify a medical diagnosis of unspecified atrial flutter. The code is valid during the current fiscal year for the submission of HIPAA-covered transactions from October 01, 2023 through September 30, 2024.

The code is commonly used in cardiology medical specialties to specify clinical concepts such as atrial fibrillation and flutter.

Unspecified diagnosis codes like I48.92 are acceptable when clinical information is unknown or not available about a particular condition. Although a more specific code is preferable, unspecified codes should be used when such codes most accurately reflect what is known about a patient's condition. Specific diagnosis codes should not be used if not supported by the patient's medical record.

Approximate Synonyms

The following clinical terms are approximate synonyms or lay terms that might be used to identify the correct diagnosis code:

  • Atrial fibrillation and flutter
  • Atrial flutter
  • Atrial flutter
  • Chronic atrial flutter
  • EKG: atrial flutter
  • Idiopathic neonatal atrial flutter
  • Neonatal dysrhythmia
  • Paroxysmal atrial flutter

Clinical Classification

Clinical Information

  • Atrial Flutter

    rapid, irregular atrial contractions caused by a block of electrical impulse conduction in the right atrium and a reentrant wave front traveling up the inter-atrial septum and down the right atrial free wall or vice versa. unlike atrial fibrillation which is caused by abnormal impulse generation, typical atrial flutter is caused by abnormal impulse conduction. as in atrial fibrillation, patients with atrial flutter cannot effectively pump blood into the lower chambers of the heart (heart ventricles).

Index to Diseases and Injuries References

The following annotation back-references for this diagnosis code are found in the injuries and diseases index. The Index to Diseases and Injuries is an alphabetical listing of medical terms, with each term mapped to one or more ICD-10-CM code(s).

Convert I48.92 to ICD-9-CM

  • ICD-9-CM Code: 427.32 - Atrial flutter
    Approximate Flag - The approximate mapping means there is not an exact match between the ICD-10 and ICD-9 codes and the mapped code is not a precise representation of the original code.

Patient Education


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:

  • Fast or slow heart beat
  • Skipping beats
  • Lightheadedness or dizziness
  • Chest pain
  • Shortness of breath
  • Sweating

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.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
