Tools for More Accurate Inpatient Cost Estimates with HCUP ...

Appendix D: ErrataThis report, The Methods Series Report #2011-04, Tools for More Accurate Inpatient CostEstimates with HCUP Databases, 2009, has an error in the appendix Table A1. Discharges withUB04 revenue codes 45x were incorrectly classified into the cost cluster OR (OperatingRoom).The correct cost cluster for UB04 revenue code 45x should have been OANC (All OtherAncillary).The All Other Ancillary tends to have a higher CCR due to the relatively greater share of costsfor labor. The Operating Room tends to have a lower CCR. In the Methods Series Report, Table2 shows that the All Other Ancillary has a CCR of 0.54 while the Operating Room has a CCR of0.41 in the 2009 data. Consequently, this incorrect classification caused the UB04 45x chargeswere assigned a lower CCR of 0.41 when they should actually be higher at 0.54. This affects3% of the total 281 million discharges.This will be corrected in the future Methods Series Report productions.We apologize for any inconvenience this may cause your organization.
