General Notes
 

Clinical Classifications Software (CCS), formerly known as Clinical Classifications for Health Policy Research (CCHPR), consists of 231 procedure categories. This system is based on ICD-9-CM codes. All procedure codes are classified.

PCCHPRn is coded as follows:

  • PCCHPRn ranges from 1 to 231 if the procedure code (PRn) is valid by the HCUP criteria, which allows a six-month window (three months before and three months after) around the official ICD-9-CM coding changes (usually October 1), for anticipation of or lags in response to official ICD-9-CM coding changes.
  • PCCHPRn is missing (.), if there is no procedure code (PRn = " ").
  • PCCHPRn is set to invalid (.A), if the procedure code (PRn) is invalid (PRVn = 1).
  • PCCHPRn is retained (values 1-231) when a valid procedure is flagged as inconsistent with age or sex (PRVn = .C). For best results, use PCCHPRn only when the procedure is valid and consistent (PRVn = 0).

Beginning in the 1998 data, this data element is called PRCCSn.

Labels

Labels for CCS, formerly known as CCHPR, categories are provided as an ASCII file in HCUP Tools: Labels and Formats.
