Code Classification

  • Diseases of the circulatory system
    (I00–I99)
    • Other forms of heart disease
      (I30-I5A)
      • Other cardiac arrhythmias
        (I49)

I49.49 is a billable diagnosis code used to specify a medical diagnosis of other premature depolarization. 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 cardiac arrhythmias (other).

Approximate Synonyms

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

  • Atrial parasystole
  • ECG: ectopic beats
  • ECG: extrasystole
  • Ectopic beats
  • Extrasystoles, short stature, hyperpigmentation, microcephaly syndrome
  • Multifocal premature beats
  • Parasystole

Clinical Classification

Clinical Information

  • Parasystole

    a cardiac arrhythmia that is caused by interaction of two independently initiated cardiac impulses of different rates from two separate foci. generally one focus is the sinoatrial node, the normal pacemaker. the ectopic focus is usually in the heart ventricle but can be in the heart atrium or the atrioventricular node. modulation of the parasystolic rhythm by the sinus rhythm depends on the completeness of entrance block surrounding the parasystolic focus.
