Conduct disorders

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 6 more specific codes instead:

  • F91.0 Conduct disorder confined to family context
  • F91.1 Conduct disorder, childhood-onset type
  • F91.2 Conduct disorder, adolescent-onset type
  • F91.3 Oppositional defiant disorder
  • F91.8 Other conduct disorders
  • F91.9 Conduct disorder, 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.

  1. FY2012 Added to the draft code set draft Conduct disorders
