Illinois Discharge Data
Data Elements, Forms and Pricing


This page is designed to allow individuals and entities interested in obtaining Illinois discharge data for a variety of purposes the means to start the data acquisition process. This site contains information on both inpatient and outpatient data available for a wide range of uses including but not limited to research, commercial health care operations, graduate thesis preparation and support for grant development.

The data available varies by service type and discharge year, with historical discharge data consisting of inpatient data from January of 1987 and outpatient surgical data starting with discharges occurring in January of 2002. These data are based on the national standard Uniform Bill (UB) with the associated periodic enhancements.

Starting in 1987 with the UB82, the collection system was updated in 1993 with additional elements from the UB92. Data beginning with discharges occurring in October of 2007, elements from the UB04 were incorporated and remain the basis of current data collection efforts. Beginning with 2009 data, additional data elements and outpatient emergency department and observation care data are now available along with outpatient surgical data from acute care hospitals and ambulatory surgical treatment centers (ASTCs).

Release of data requires application approval, signed data use agreement and payment of the necessary fee based on data usage and entity category. Contacts for data request/application vary with the type of applicant and intended usage. Representatives of the Media should contact the IDPH Public Information Office, while all other requestors/applicants should contact the program data steward.
