ICD Code I49.49

ICD code I49.49 is other types of premature heartbeats or irregular heart rhythms that start in the heart but are not specifically classified elsewhere.

1. Presence of premature cardiac depolarizations not classified under more specific arrhythmia codes

2. Documented episodes of premature contractions originating from atrial, junctional, or ventricular sites, excluding those with a defined etiology

3. Electrocardiogram (ECG) evidence of early depolarization events that do not meet criteria for common arrhythmias such as atrial fibrillation, atrial flutter, or specific types of premature beats

4. Patient may experience palpitations, irregular heartbeat, or skipped beats

5. Absence of structural heart disease or other underlying cardiac conditions that would explain the premature depolarizations

6. Symptoms may include dizziness, lightheadedness, or chest discomfort associated with the premature beats

7. Exclusion of reversible causes such as electrolyte imbalances, medication effects, or acute illness
