Congenital malformations of the nervous system (Q00-Q07)
Browse all the diagnosis codes used for congenital malformations of the nervous system (q00-q07). For easy navigation, the diagnosis codes are sorted in alphabetical order and grouped by sections. Each section is clearly marked with its description, and the corresponding three-digit code range.
