Beginning in Fiscal Year 2008, the Mental Health Substance Abuse Clinical Classifications Software 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 The CCS-MHSA software is no longer updated as a stand-alone tool, however archival versions of the software are available. For more information on the integration, please see the 2010 CCS Software and User’s Guide at the link below: http://www.hcup-us.ahrq.gov/toolssoftware/ccs/ccs.jsp

These versions of the tool should be employed by users who want the prior categorization scheme.
