About Q75

Q75 is the ICD-10-CM diagnosis code for other congenital malformations of skull and face bones. It belongs to block Q65-Q79 (congenital malformations and deformations of the musculoskeletal 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 8 subcodes must be used instead.

To report this condition, pick the subcode that matches the documentation: Q75.0 (craniosynostosis), Q75.1 (dysostosis), Q75.2 (Hypertelorism), Q75.3 (Macrocephaly), Q75.4 (dysostosis), Q75.5 (dysostosis), Q75.8 (bones) and Q75.9 (unspecified).

Don't report Q75 together with the conditions in its Excludes1 note: congenital malformation of face NOS (Q18.-), congenital malformation syndromes classified to Q87.-, dentofacial anomalies [including malocclusion] (M26.-), musculoskeletal deformities of head and face (Q67.0-Q67.4) and 4 more.

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