ICD 9 and Diagnostic and Statistical Manual of Mental Disorders (DSM) is the standard used by mental health professionals for diagnosing disorders. This simple application is a list of diagnostic codes that can be sorted by code or alphabetically by name. It has a search feature that allows the user to search codes and names by partial character string. When the user clicks on a list item a detail view of diagnostic criteria for the disorder clicked opens. I also added the Global Assessment of Functioning (GAF) score chart and an overview of a five axis diagnosis.
