Q23

Congenital malformations of aortic and mitral valves

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 7 more specific codes instead:

  • Q23.0 Congenital stenosis of aortic valve
  • Q23.1 Congenital insufficiency of aortic valve
  • Q23.2 Congenital mitral stenosis
  • Q23.3 Congenital mitral insufficiency
  • Q23.4 Hypoplastic left heart syndrome
  • Q23.8 Other congenital malformations of aortic and mitral valves (also a header)
  • Q23.9 Congenital malformation of aortic and mitral valves, 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.
