ICD-10-CM Code I49.1
Atrial premature depolarization
Billable CodeBillable codes are sufficient justification for admission to an acute care hospital when used a principal diagnosis.
I49.1 is a billable ICD code used to specify a diagnosis of atrial premature depolarization. A 'billable code' is detailed enough to be used to specify a medical diagnosis.
The ICD code I491 is used to code Premature atrial contraction
Premature atrial contractions (PACs), also known as atrial premature complexes (APC) or atrial premature beats (APB), are a common cardiac dysrhythmia characterized by premature heartbeats originating in the atria. While the sinoatrial node typically regulates the heartbeat during normal sinus rhythm, PACs occur when another region of the atria depolarizes before the sinoatrial node and thus triggers a premature heartbeat.The exact cause of PACs is unclear; while several predisposing conditions exist, PACs commonly occur in healthy young and elderly people without heart disease, and by themselves are not considered an abnormal finding. PACs are often completely asymptomatic and may be noted only with Holter monitoring, but occasionally they can be perceived as a skipped beat or a jolt in the chest. In most cases, no treatment other than reassurance is needed for PACs, although medications such as beta blockers can reduce the frequency of symptomatic PACs.

Equivalent ICD-9 Code GENERAL EQUIVALENCE MAPPINGS (GEM)
This is the official exact match mapping between ICD9 and ICD10, as provided by the General Equivalency mapping crosswalk. This means that in all cases where the ICD9 code 427.61 was previously used, I49.1 is the appropriate modern ICD10 code.
