ICD10 code of Bardet-Biedl Syndrome and ICD9 code

The medical classification for Bardet-Biedl Syndrome is primarily identified by the ICD-10 code Q87.89, which covers "other specified congenital malformation syndromes." Under the older ICD-9-CM classification system, Bardet-Biedl Syndrome was historically coded as 759.89.

What is the clinical significance of classifying Bardet-Biedl Syndrome?

Accurate coding for Bardet-Biedl Syndrome is essential for medical billing, insurance authorization, and public health tracking. Because Bardet-Biedl Syndrome is a complex, multi-system ciliopathy, physicians often use these codes in conjunction with secondary codes to document specific manifestations, such as retinitis pigmentosa, polydactyly, or renal abnormalities. Proper documentation ensures that the multi-disciplinary care required by patients is appropriately recognized by healthcare systems and payers.

What are the primary diagnostic criteria for Bardet-Biedl Syndrome?

Diagnosis of Bardet-Biedl Syndrome is typically based on the presence of primary and secondary clinical features as defined by Beales et al. Clinical diagnosis often involves genetic testing to confirm mutations in one of the more than 20 genes identified as causes of Bardet-Biedl Syndrome. The primary features that lead clinicians to investigate this diagnosis include:

• Rod-cone dystrophy: Progressive vision loss usually starting in childhood.


• Postaxial polydactyly: Extra digits on the hands or feet present at birth.


• Obesity: Often presenting in early childhood and involving truncal fat distribution.


• Renal anomalies: Structural or functional kidney impairment, which is a major factor in the long-term prognosis of Bardet-Biedl Syndrome.


• Learning disabilities: Cognitive impairment ranging from mild to moderate.


• Hypogonadism: Delayed or incomplete sexual development.

Is Bardet-Biedl Syndrome hereditary?

Yes, Bardet-Biedl Syndrome is an autosomal recessive genetic condition. This means that an individual must inherit two mutated copies of a causative gene—one from each parent—to manifest the disorder. Parents of a child with Bardet-Biedl Syndrome are typically asymptomatic carriers, each carrying one copy of the mutated gene. Genetic counseling is strongly recommended for families to understand the 25% recurrence risk for each subsequent pregnancy.

How does the community support those with Bardet-Biedl Syndrome?

Living with a rare, multi-systemic condition can be isolating. At DiseaseMaps.org, 121 people with Bardet-Biedl Syndrome have joined the community to share their experiences, symptom management strategies, and emotional support. Connecting with others who navigate the same medical challenges can provide invaluable insights into day-to-day life, navigating specialized care, and finding localized resources.

Next steps

• Consult with a clinical geneticist to confirm a diagnosis through molecular genetic testing.


• Establish a care team including an ophthalmologist, nephrologist, endocrinologist, and genetic counselor.


• Connect with the DiseaseMaps.org community to share experiences with others living with the condition.


• Monitor the NIH Genetic and Rare Diseases (GARD) Information Center for updates on clinical trials and research.
