Williams Syndrome
Code Q93.82 was created to identify Williams Syndrome (WS). WS, also known as Williams Beuren syndrome (WBS), is a multi-system, neurodevelopmental genetic disorder caused by a “micro-deletion” on the long arm of chromosome 7 (7q11.23) associated with the loss of 26-28 contiguous genes. Both medical and cognitive problems are present throughout the lifespan of those with WS. The most common medical problems include cardiovascular abnormalities, various endocrine abnormalities, gastrointestinal issues and musculoskeletal problems. Neurodevelopmental aspects of WS include mild to moderate intellectual disability and learning disabilities. Anxiety and other behavioral/emotional issues are also typical in WS...

Article Overview
This premium article provides a coding-focused overview of Williams syndrome, a multisystem genetic condition with medical, neurodevelopmental, and characteristic physical features. It is intended for coders, clinicians, and researchers who need to understand why a dedicated diagnosis code was created and what broad clinical domains are associated with the disorder. The article also discusses the role of the Williams Syndrome Association and the research and surveillance value of more specific identification.
Why This Topic Matters
Accurate identification of Williams syndrome affects diagnosis tracking, research, surveillance, and the organization of clinical and coding data for a rare genetic disorder.
