Complications and ill-defined descriptions of heart disease

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 9 more specific codes instead:

  • I51.0 Cardiac septal defect, acquired
  • I51.1 Rupture of chordae tendineae, not elsewhere classified
  • I51.2 Rupture of papillary muscle, not elsewhere classified
  • I51.3 Intracardiac thrombosis, not elsewhere classified
  • I51.4 Myocarditis, unspecified
  • I51.5 Myocardial degeneration
  • I51.7 Cardiomegaly
  • I51.8 Other ill-defined heart diseases (also a header)
  • I51.9 Heart disease, 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.
