Patient EducationClinical

Craniofacial Abnormalities

Craniofacial is a medical term that relates to the bones of the skull and face. Craniofacial abnormalities are birth defects of the face or head. Some, like cleft lip and palate, are among the most common of all birth defects. Others are very rare. Most of them affect how a person's face or head looks.

Questions About Q75.002Overview

What is the ICD-10 code for craniosynostosis, unspecified type, bilateral?

The ICD-10-CM code for craniosynostosis, unspecified type, bilateral is Q75.002 (sometimes written as Q75002). It is billable on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

Is Q75.002 (Craniosynostosis, unspecified) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report craniosynostosis, unspecified type, bilateral on HIPAA-covered claims from October 1, 2026 through September 30, 2027.

What MS-DRG does Q75.002 group to?

When craniosynostosis, unspecified type, bilateral is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 566, 565, with relative weights from 0.7374 to 1.4909 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q75.002 exempt from POA reporting?

Yes. CMS lists this code among those exempt from present on admission reporting, so hospitals do not assign a POA indicator for craniosynostosis, unspecified type, bilateral on inpatient claims. The code appears in the Congenital malformations and deformations of the musculoskeletal system (Q65-Q79) range of the CMS exempt list.

Can Q75.002 be reported with a code from Q18?

Not as a rule. The Excludes1 note at Q75, which applies to Q75.002, lists "congenital malformation of face NOS (Q18.-)". An Excludes1 note means the excluded code is never reported together with this one; the only exception is when the two conditions are unrelated to each other (Official Guidelines, Section I.A.12.a).
