when did dsm five start being used?
This means that you should already be using it to diagnose. DSM-5 lists both ICD-9 and ICD-10 codes - ICD-9 is listed first, and ICD-10 is listed second in parentheses: You should use ICD-9 codes (in this example, 305.00 for alcohol use disorder, mild) until 10/1/15. After 10/1/15, you should use ICD-10 codes (in this example, F10.10).
