Q07Other congenital malformations of nervous system

Q07 is the ICD-10-CM diagnosis code for other congenital malformations of nervous system. It belongs to block Q00-Q07 (congenital malformations of the nervous system) and chapter 17 (congenital malformations, deformations, chromosomal abnormalities, and genetic disorders). It is a header code, so it can't be reported by itself; one of its 3 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q07.0 (syndrome), Q07.8 (system) and Q07.9 (unspecified).

The conditions in its Excludes2 note aren't part of Q07, but may be coded alongside it if the patient has both: congenital central alveolar hypoventilation syndrome (G47.35), familial dysautonomia [Riley-Day] (G90.1) and neurofibromatosis (nonmalignant) (Q85.0-).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015 and hasn't changed since.
