ICD10 code of Nager Syndrome and ICD9 code

Nager syndrome, a rare form of acrofacial dysostosis, does not have a unique, dedicated ICD-10 or ICD-9 code. Clinicians typically use broader classification codes such as ICD-10 Q87.0 (Congenital malformation syndromes predominantly affecting facial appearance) or ICD-9 759.89 (Other specified congenital anomalies) to document the condition in medical records.

What is the clinical classification of Nager syndrome?

Because Nager syndrome is a rare genetic condition, it is categorized under broader clinical umbrella terms in international coding systems. While there is no specific code for Nager syndrome itself, medical professionals use the aforementioned ICD-10 and ICD-9 codes to capture the craniofacial and limb abnormalities characteristic of the diagnosis. Accurate coding is essential for insurance authorization of the multidisciplinary care required for Nager syndrome patients.

What are the primary characteristics of Nager syndrome?

Nager syndrome is primarily defined by the combination of severe mandibular hypoplasia (underdeveloped jaw) and preaxial limb defects. Patients with Nager syndrome often face complex medical challenges throughout their lives. Key clinical features include:

• Down-slanting palpebral fissures and coloboma of the lower eyelids.


• Severe micrognathia, which may cause significant airway obstruction.


• Limb abnormalities, most commonly affecting the thumbs (hypoplasia or aplasia) and the radius bone of the forearm.


• Hearing loss, frequently conductive in nature due to malformed middle ear structures.


• Feeding and speech difficulties resulting from the unique craniofacial structure of Nager syndrome.

How is Nager syndrome managed?

Management of Nager syndrome requires a dedicated team of specialists, including craniofacial surgeons, otolaryngologists, geneticists, and speech therapists. At DiseaseMaps.org, we have observed that 16 members within our community are currently navigating the complexities of Nager syndrome, emphasizing the importance of shared experiences in managing this rare condition.

Next steps

• Consult with a clinical geneticist to confirm the diagnosis and discuss the inheritance patterns associated with Nager syndrome.


• Connect with the 16 members of the DiseaseMaps.org community who are living with Nager syndrome to share resources and support.


• Schedule evaluations with a multidisciplinary craniofacial team to address airway, feeding, and orthopedic needs.
