About Q75.0

Q75.0 is the ICD-10-CM diagnosis code for craniosynostosis. It belongs to category Q75 (other congenital malformations of skull and face bones), 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 7 subcodes must be used instead.

Within Q75 (other congenital malformations of skull and face bones), Q75.0 is specifically for craniosynostosis. Related codes cover craniofacial dysostosis (Q75.1), Hypertelorism (Q75.2), Macrocephaly (Q75.3), Mandibulofacial dysostosis (Q75.4), Oculomandibular dysostosis (Q75.5), other specified congenital malformations of skull and face bones (Q75.8) and congenital malformation of skull and face bones, unspecified (Q75.9).

To report this condition, pick the subcode that matches the documentation: Q75.00 (unspecified), Q75.01 (craniosynostosis), Q75.02 (craniosynostosis), Q75.03 (craniosynostosis), Q75.04 (craniosynostosis), Q75.05 (craniosynostosis) and Q75.08 (craniosynostosis).

It has been part of ICD-10-CM since the code set took effect on October 1, 2015, and changed in FY2024 (expanded into subcodes).

Before ICD-10, this condition was coded in ICD-9-CM as 756.0 (anomalies of skull and face bones).
