ICD10 code of Axenfeld-Rieger Syndrome and ICD9 code

Axenfeld-Rieger Syndrome is classified under ICD-10 code Q15.8 (Other specified congenital malformations of eye) and historically under ICD-9 code 743.49 (Other specified anomalies of anterior segment of eye). These codes are used for medical billing and tracking, as there is no single, unique code dedicated exclusively to Axenfeld-Rieger Syndrome.

What exactly is Axenfeld-Rieger Syndrome?

Axenfeld-Rieger Syndrome is a rare genetic disorder characterized by developmental abnormalities of the anterior segment of the eye, which can lead to glaucoma in approximately 50% of affected individuals. Beyond the eyes, Axenfeld-Rieger Syndrome often involves systemic features, including dental hypodontia (missing teeth), redundant periumbilical skin, and mild craniofacial dysmorphism.

How is Axenfeld-Rieger Syndrome diagnosed?

Diagnosis is primarily clinical, based on a comprehensive examination by an ophthalmologist and a geneticist. Because Axenfeld-Rieger Syndrome is caused by mutations in genes like PITX2 or FOXC1, molecular genetic testing is often used to confirm the diagnosis and provide clarity for family planning.

Is Axenfeld-Rieger Syndrome hereditary?

Yes, Axenfeld-Rieger Syndrome typically follows an autosomal dominant inheritance pattern. This means that an affected individual has a 50% chance of passing the causative gene mutation to each of their children. Genetic counseling is vital for families navigating the implications of Axenfeld-Rieger Syndrome.

What are the common clinical features?

• Posterior embryotoxon (a prominent Schwalbe's line in the eye).


• Iris hypoplasia or corectopia (displacement of the pupil).


• Microdontia or hypodontia (small or missing teeth).


• Midface hypoplasia (a flattened appearance of the middle of the face).


• Increased risk of early-onset glaucoma.

Next steps

• Schedule a baseline evaluation with a specialist ophthalmologist experienced in pediatric glaucoma.


• Consult with a clinical geneticist to discuss potential genetic testing for Axenfeld-Rieger Syndrome.
