I49.8

Other specified 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.

Billable FY2016 to FY2026, and a category header from FY2027.

Submit one of these 3 more specific codes instead:

  • I49.81 Brugada syndrome
  • I49.82 Ventricular bigeminy
  • I49.89 Other specified cardiac arrhythmias not elsewhere classified

Use instead:

  • G90.A Postural orthostatic tachycardia syndrome [POTS] stated for FY2022

What has happened to this code

Every change the publisher made, from 2007 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.

  1. FY2007 Added to the draft code set draft Other specified cardiac arrhythmias
  2. FY2027 Stopped being billable

Official coding rules
