I49

Other cardiac arrhythmias

Not billableICD-10-CM diagnosis code.

This code exists but cannot be submitted on its own. It groups the more specific codes beneath it.

A category header for its whole life, FY2016 onwards. It has never been valid for submission on its own.

Submit one of these 8 more specific codes instead:

  • I49.0 Ventricular fibrillation and flutter (also a header)
  • I49.1 Atrial premature depolarization
  • I49.2 Junctional premature depolarization
  • I49.3 Ventricular premature depolarization
  • I49.4 Other and unspecified premature depolarization (also a header)
  • I49.5 Sick sinus syndrome
  • I49.8 Other specified cardiac arrhythmias (also a header)
  • I49.9 Cardiac arrhythmia, unspecified

What has happened to this code

Every change the publisher made, from 2012 to now. Entries marked draft are from the pre-implementation releases: ICD-10 took effect on 1 October 2015, so nothing before FY2016 was ever valid on a claim.

Official coding rules

Published by CDC for FY2027. A rule attached to a category binds every code beneath it, so the rules inherited from this code's ancestors are shown with the code they come from.
