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 Q75.2Overview

Is Q75.2 (Other congenital malformations of skull and face bones) a billable code?

Yes. This is a billable ICD-10-CM code, specific enough to report hypertelorism on HIPAA-covered claims from October 1, 2025 through September 30, 2026.

What MS-DRG does Q75.2 group to?

When hypertelorism is the principal diagnosis on an inpatient stay, it groups to MS-DRG 564, 565, 566, with relative weights from 0.7493 to 1.5436 depending on complications. Higher weights mean higher Medicare reimbursement.

Is Q75.2 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 hypertelorism on inpatient claims.

What is the ICD-9 equivalent of Q75.2?

Under the General Equivalence Mappings, hypertelorism converts to ICD-9-CM 756.0 (anomal skull/face bones). The mapping is approximate, so confirm the match fits the documentation.

Footnotes

[1] Not chronic - A diagnosis code that does not fit the criteria for chronic condition (duration, ongoing medical treatment, and limitations) is considered not chronic. Some codes designated as not chronic are acute conditions. Other diagnosis codes that indicate a possible chronic condition, but for which the duration of the illness is not specified in the code description (i.e., we do not know the condition has lasted 12 months or longer) also are considered not chronic.
