Psych ICD10 makes the conversion from ICD9 mental health codes to ICD10 easy. It has only the mental health codes, so you dont have to navigate through irrelevant codes to find what you want. Touch an ICD9 code and see the corresponding ICD10 code. The DSM-V takes effect in October 2015. This app will help psychiatrists, psychiatric nurse practitioners, psychologists, and other mental health specialists during the transition.
