Ongoing analyses are being conducted now that ICD-10-PCS-coded data is available. Preliminary findings suggest some unexpected discontinuities between the tools based on ICD-9-CM procedures and the beta version of tools based on ICD-10-PCS. In 2013, reverse mapping validation of 100 percent of the ICD-10-PCS procedure CCS assignments was conducted to verify the accuracy of mapping of the beta version of the CCS. The accuracy of the initial assessment was verified by reviewing a 20 percent sample of the coding assignments. Initial maps were completed in September 2011. When the coders did not initially map a code to the same CCS category, the team reviewed the discrepancies and came to consensus for the CCS assignment, with the help of a third coder if necessary. Two coders each made a CCS assignment for each code based on the GEMs. These initial GEMs were reviewed by credentialed coders trained in both ICD-9-CM and ICD-10-PCS to ensure the validity of the map for use in formulating the CCS categories. The translation was based on forward and backward mapping using the GEMs. No dually coded data were available at the time the CCS categories were translated to ICD-10-PCS. The initial mapping was completed by linking ICD-10-PCS codes to the CCS for ICD-9-CM classification assignments via the General Equivalence Mappings (GEMs) available from the Centers for Medicare & Medicaid Services (CMS) website (see for more information on GEMS). In preparation for the October 2015 implementation of ICD-10-PCS, the procedure CCS tool from HCUP were converted to the new coding system. It can be a useful way to categorize procedures when exploring data and can serve as a tool for reporting statistical information on hospitalizations.ĭevelopment History of the CCS for ICD-10-PCS Procedures (beta version) The CCS can be used to identify populations for procedure-specific studies or to develop statistical reports about relatively specific procedures.
It is based on the CCS for ICD-9-CM procedures and attempts to map ICD-10-PCS codes into the same categories. The ICD-10-PCS's multitude of codes-more than 77,000 procedure codes-are collapsed into a manageable number of clinically meaningful categories that are sometimes more useful for presenting descriptive statistics than are individual ICD-10-PCS codes. CCS is based on the International Classification of Diseases, 10th Revision, Procedure Coding System (ICD-10-PCS), a uniform and standardized coding system for procedures. The Clinical Classifications Software (CCS) for ICD-10-PCS (beta version) is a procedure categorization scheme that can be employed in many types of projects analyzing data on procedures.
