ICD10 code of Beckwith-Wiedemann Syndrome and ICD9 code

The ICD-10-CM code for Beckwith-Wiedemann syndrome is Q87.3, while the older ICD-9-CM classification is 759.89. These codes are essential for medical billing, insurance authorization, and identifying clinical records for patients living with this overgrowth disorder.

What exactly is Beckwith-Wiedemann syndrome?

Beckwith-Wiedemann syndrome (BWS) is a congenital overgrowth disorder characterized by an increased risk of childhood tumors and distinctive physical features. It is a complex genetic condition often described as an imprinting disorder, meaning it involves the abnormal expression of genes on chromosome 11p15.5. At DiseaseMaps.org, we currently support a community of 241 individuals who are navigating the unique clinical journey associated with Beckwith-Wiedemann syndrome, sharing valuable insights into daily management and long-term care.

How is Beckwith-Wiedemann syndrome diagnosed and classified?

Diagnosis of Beckwith-Wiedemann syndrome is primarily clinical, often utilizing a scoring system based on specific features like macroglossia (enlarged tongue), abdominal wall defects (such as omphalocele), and hemihyperplasia (overgrowth of one side of the body). Because Beckwith-Wiedemann syndrome is a spectrum disorder, the molecular diagnosis is confirmed through genetic testing that looks for epigenetic changes or DNA methylation defects. The ICD-10 code Q87.3 is used to categorize this condition formally in the healthcare system, ensuring that clinicians can track the necessity for specialized screening protocols.

Why are medical coding and documentation important for this condition?

Accurate coding is more than just an administrative task; it is a vital step in ensuring that patients with Beckwith-Wiedemann syndrome receive the intensive surveillance they require. Because of the elevated risk of embryonal tumors—such as Wilms tumor and hepatoblastoma—early and precise diagnosis via the correct ICD codes helps facilitate:

• Regular abdominal ultrasounds, typically performed every 3 months until at least age 8.


• Serum alpha-fetoprotein (AFP) screening to monitor for liver-related malignancies.


• Coordinated care between pediatric oncologists, geneticists, and endocrinologists.


• Insurance approval for necessary surgeries related to macroglossia or abdominal wall closure.

Is Beckwith-Wiedemann syndrome hereditary?

In the vast majority of cases (approximately 85-90%), Beckwith-Wiedemann syndrome occurs sporadically, meaning it is not inherited from the parents. However, in a small percentage of families, there is a genetic predisposition that can be passed down. A clinical geneticist can help families understand the underlying cause of their specific case, whether it involves paternal uniparental disomy, loss of methylation, or a mutation in the CDKN1C gene. Understanding the genetic mechanism is crucial not only for the patient but also for family planning and genetic counseling.

Next steps

• Consult a clinical geneticist to confirm the molecular subtype of Beckwith-Wiedemann syndrome, as this influences tumor screening protocols.


• Establish a long-term relationship with a pediatric oncology center that specializes in overgrowth syndromes for consistent surveillance.


• Connect with the 241 members of the DiseaseMaps community to share experiences and find emotional support from families facing similar diagnostic and care challenges.


• Maintain a comprehensive "medical passport" that lists the patient’s specific molecular findings and recommended screening schedule.
