Beginning in Fiscal Year 2008, the Clinical Classifications Software for Mental Health and Substance Abuse tool (CCS-MHSA) was permanently integrated into the Clinical Classifications Software tool for diagnoses (CCS). The CCS-MHSA software is no longer updated as a stand-alone tool. To use the MHSA CCS categories, please use the CCS software at the following link: http://www.hcup-us.ahrq.gov/toolssoftware/ccs/ccs.jsp
