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 4 more specific codes instead:

  • Q03.0 Malformations of aqueduct of Sylvius
  • Q03.1 Atresia of foramina of Magendie and Luschka
  • Q03.8 Other congenital hydrocephalus
  • Q03.9 Congenital hydrocephalus, 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 Congenital hydrocephalus
