ICD10 code of Crouzon syndrome and ICD9 code

Crouzon syndrome is classified under the ICD-10-CM code Q75.0 (Craniosynostosis) and the ICD-9-CM code 756.0 (Anomalies of skull and face bones). These billing codes are essential for healthcare providers to document the condition, though they represent the broader category of craniosynostosis syndromes rather than a unique code exclusive to Crouzon syndrome.

What is the clinical classification of Crouzon syndrome?

Crouzon syndrome is a rare genetic disorder characterized by the premature fusion of certain skull bones (craniosynostosis), which prevents the skull from growing normally and affects the shape of the head and face. Because the condition is a form of craniosynostosis, medical coding often utilizes the ICD-10 code Q75.0. Clinically, Crouzon syndrome is identified by its distinct craniofacial features, including widely spaced eyes (hypertelorism), shallow eye sockets (proptosis), and an underdeveloped upper jaw. Within the DiseaseMaps.org community, 91 individuals have shared their experiences, highlighting the diverse ways this diagnosis impacts daily life and long-term health management.

How is Crouzon syndrome diagnosed and coded?

Diagnosis of Crouzon syndrome is typically made through a combination of clinical evaluation and genetic testing. Physicians often look for the hallmark signs of craniosynostosis shortly after birth. When billing for services related to Crouzon syndrome, medical professionals use ICD-10-CM Q75.0, which encompasses various syndromes involving the premature closure of cranial sutures. In older medical records, the ICD-9-CM code 756.0 was used to describe these specific anomalies of the skull and face bones. It is common for patients to have multiple secondary codes in their records to account for related complications, such as obstructive sleep apnea or visual impairments.

Is Crouzon syndrome hereditary?

Crouzon syndrome is an autosomal dominant condition, meaning that an affected parent has a 50% chance of passing the mutated FGFR2 gene to each child. However, it is important to note that many cases occur as a "de novo" or spontaneous mutation in an individual with no previous family history of the condition. Genetic counseling is highly recommended for families navigating a new diagnosis of Crouzon syndrome to understand the recurrence risks and the molecular basis of the disorder.

What are the common clinical features managed in Crouzon syndrome?

Management of Crouzon syndrome requires a multidisciplinary approach involving pediatric neurosurgeons, craniofacial surgeons, ophthalmologists, and geneticists. The following list details common clinical areas that may require ongoing monitoring:

• Craniosynostosis: Monitoring of intracranial pressure and potential surgical intervention to allow for brain growth.


• Ophthalmological care: Regular screenings for exposure keratopathy and optic nerve health due to shallow orbits.


• Respiratory function: Assessment for obstructive sleep apnea, which is prevalent due to midface hypoplasia.


• Dental/Orthodontic health: Management of dental crowding and malocclusion, often requiring staged surgical procedures.


• Audiology: Evaluation for conductive hearing loss, which is frequently associated with the condition.

Next steps

• Consult a craniofacial team at a specialized pediatric hospital to establish a comprehensive care plan.


• Connect with the 91 members of the DiseaseMaps.org community who share lived experiences with Crouzon syndrome to find peer support.


• Request a referral to a clinical geneticist for formal testing and family planning guidance.


• Maintain a consolidated file of your ICD-10 documentation to ensure coordination between specialists.
