Other congenital malformations of circulatory system

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 6 more specific codes instead:

  • Q28.0 Arteriovenous malformation of precerebral vessels
  • Q28.1 Other malformations of precerebral vessels
  • Q28.2 Arteriovenous malformation of cerebral vessels
  • Q28.3 Other malformations of cerebral vessels
  • Q28.8 Other specified congenital malformations of circulatory system
  • Q28.9 Congenital malformation of circulatory system, 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.
