Anytime you visit either a WS Clinic or your local physicians please tell them about the new ICD-10 diagnostic code for Williams syndrome, and ask them to put it in their records of use on all procedure reports.  ICD-10 codes are used primarily by insurance providers but they are also extremely important to the research community.  Your physicians use of the ICD-10 code specific to Williams syndrome can truly make a difference for future research on Williams syndrome.
