This total charge data can be converted into cost estimates using the CCR Files, which include hospital-wide values of the all-payer inpatient cost-to-charge ratio for nearly every hospital in the participating NIS, KID, NRD, and SID. The CCR Files are updated annually and available for the HCUP inpatient databases beginning with 2001 data.
