General Notes
 

Clinical Classifications Software (CCS) for services and procedures coded by CPT consists of 244 categories. This system is clinically based with all procedure codes classified.

CPTCCSn is coded as follows:

  • 1 to 244 if the procedure code (CPTn) is valid by the HCUP criteria. The HCUP criteria for procedure validation allows a year window (six months before and six months after) around the official CPT coding changes, for anticipation of or lags in response to official CPT coding changes.
  • CPTCCSn is missing (.), if there is no procedure code (CPTn = " ").
  • CPTCCSn is set to invalid (.A), if the procedure code (CPTRn) is invalid by the HCUP criteria (ECPT01).
  • CPTCCSn is set to inconsistent (.C), if the procedure code (CPTn) is inconsistent with age (ECPT02) or sex of the patient (ECPT03).

More information on the CCS for CPT services and procedures is available under the HCUP Tools and Software page on HCUP-US.
