Williams Syndrome ICD10 code: Q93.8
Williams Syndrome ICD9 code: 759.89
Williams syndrome is a genetic disorder characterized by distinct facial features, cardiovascular problems, developmental delays, and intellectual disabilities. In the International Classification of Diseases, 10th Revision (ICD-10), Williams syndrome is assigned the code Q93.8. This code falls under the category of "Other specified chromosome abnormalities" in the chapter on "Congenital malformations, deformations, and chromosomal abnormalities."
In the previous version, the 9th Revision of the ICD (ICD-9), Williams syndrome was classified under code 758.1. This code was used for "Other conditions due to autosomal anomalies" in the section on "Congenital anomalies of the circulatory system."
It is important to note that ICD-10 codes provide more specificity and detail compared to ICD-9 codes, allowing for better classification and tracking of medical conditions. The transition from ICD-9 to ICD-10 was made to enhance accuracy and improve healthcare data analysis and reporting.
