CCS is based on the <em>International Classification of Diseases, 9th Revision, Clinical Modification</em> (ICD-9-CM), a uniform and standardized coding system. The ICD-9-CM's multitude of codes - over 14,000 diagnosis codes and 3,900 procedure codes - are collapsed into a smaller number of clinically meaningful categories that are sometimes more useful for presenting descriptive statistics than are individual ICD-9-CM codes. <br><br> For example, CCS can be used to identify populations for disease- or procedure-specific studies or to develop statistical reports providing information (such as charges and length of stay) about relatively specific conditions. CCS was formerly called the Clinical Classifications for Health Policy Research (CCHPR). <br><br> The CCS now includes categories from the Clinical Classifications Software for Mental Health and Substance Abuse (CCS-MHSA). These categories replace the original CCS categories for mental health and substance abuse. More specifically, the CCS single-level software includes the CCS-MHSA general categories, and the CCS multi-level software includes the CCS-MHSA specific categories. <br><br><strong> A special archival version of the single-level CCS for diagnoses is available for users doing longitudinal analysis involving past years. This version uses the original CCS format for mental health conditions (65-75), and applies it to the latest ICD-9-CM codes. The archival tool can be found in the ASCII program files download section below. </strong> <br><br> <strong>Empty Categories:</strong><br /> Please note that because of revisions to the CCS, single-level category 150 and multi-level categories 11.3.7.3 and 9.8.1 do not contain any diagnosis codes as of FY 2008. Also, single-level category 260 does not contain any E Codes as of FY 2005. <br><br> <strong>Suicide E codes: Mechanism of Injury:</strong><br /> Suicide E Codes (external cause of injury codes) are assigned to CCS category 662, "Suicide and Self–Inflicted Injury". However, for users who wish to assign these E codes to a mechanism of injury CCS, an optional CCS category has been provided in the single-level diagnosis tool ($dxref 2013.csv) for each code. These optional CCS categories follow the CDC’s classification of E codes into mechanism of injury categories such as firearm or poisoning, Interested users should simply reassign suicide codes from category 662 to the optional secondary CCS categories as detailed in column five of $dxref 2013.csv. The code below gives an example of the reassignment process. Similar code can be used to reassign the CCS label: <br><br> <em> Filename inraw "c:\tools\ccs\$DXREF 2013.csv" ;<br /> /*****************************************/<br /> /* Make a SAS format Using the Optional */<br /> /* Suicide Mechansism CCS Category. */<br /> /*****************************************/v data new;<br />       infile inraw dsd dlm=',' end = eof firstobs=3 missover;<br />          input start : $char5.<br />               Oldccs : $char4.<br />               Value1 : $char70.<br />               Value2 : $char70.<br />               Label : $char4.<br />               Value3 : $char70.<br />               ;<br />          retain hlo "   ";<br />       fmtname = "$ccs" ;<br />       type = "   " ;<br />       output;<br /> <br />       if eof then do ;<br />          start = "   " ;<br />          vlabel = "   " ;<br />          hlo = "o";<br />          output ;<br />       end ;<br /> run;<br /> proc format cntlin = new ;<br /> run;<br /> /*****************************************/<br /> /* Reassign CCS to the Optional CCS for */<br /> /* Suicide mechanism using SAS format. */<br /> /*****************************************/<br /> data test;<br />       Set ecodedata;<br />       Ccs = put(ecode,$ccs.)<br /> run;<br /> </em> <br><br> For more information on the CCS, select to access the <a href="ccsfactsheet.jsp">CCS Fact Sheet</a>. <br><br> For <a href="#download">downloading information</a>, select to access the CCS Software and User's guide (which can be viewed in Portable Document Format). <br><br> This documentation contains: <ul> <li>A brief description of the CCS categorization scheme</li> <li>Electronic files in ASCII format containing the translation of ICD-9-CM diagnosis and procedure codes into CCS categories. <strong>Note: There are no new diagnosis or procedure codes for FY 2015.</strong></li> </ul></div> </td></tr> <tr><td align="left" class="pagetext"><a href="#return">Return to Contents</a></td></tr> <tr><td> </td></tr> <tr><td> <div class="texttitle"><a name="tech">Technical Advice</a></div><div class="pagetext"> <br> The CCS documentation describes the electronic translation files, provides warnings about ICD-9-CM coding changes over time, and summarizes how to use the files.</div> <br> </td></tr> <tr><td align="left" class="pagetext"><a href="#return">Return to Contents</a></td></tr> <tr><td> </td></tr> <tr><td> <div class="texttitle"><a name="examples">Examples of CCS tool Usage</a></div><div class="pagetext"> <br> The HCUP CCS tool is used in the risk adjustment approach for CMS' readmission measures that are now part of the Hospital Readmissions Reduction Program (HRRP).</div> <br> </td></tr> <tr><td align="left" class="pagetext"><a href="#return">Return to Contents</a></td></tr> <tr><td> </td></tr> <tr><td> <div class="texttitle"><p><a name="download">Downloading Information for CCS Software and User's Guide</a></p></div> <div class="pagetext"> <p><strong>Note: : There are no new diagnosis or procedure codes for FY 2015.</strong></p> <p><strong>Shift-click from this Web page:</strong> Your browser may support loading the files for CCS and the Software and User's Guide from this Web page.
