In 1976, New Jersey’s Department of Health and Senior Services (Department) was among the first states to collect utilization data on hospital inpatients. Utilization data includes information on admission and discharge dates, the hospital and the services rendered, charges, and insurers. Since 1981, inpatient data has been collected through Uniform Bill-Patient Summaries (UB). Starting in 2004, the Department also collects outpatient data from hospital emergency departments (ED), on UB forms, in accordance with New Jersey laws and Department regulations.
Until 1992, UB data and hospital cost data produced Diagnosis Related Group rates (DRGs) for New Jersey hospitals. The repeal of DRGs with the Health Care Reform Act (Chapter 160, enacted on November 30, 1992) ended the DRG payments to hospitals. Since then, UB data supports Department and State public policy research, as well as the Department’s public health surveillance of asthma, diabetes, complications of pregnancy, and pediatric hospitalizations that could have been averted by timely outpatient care.
While the Department has always provided privacy-protected UB data to the public for purchase, the Department is not obligated to sort, filter, or analyze the data provided in response to these requests.
The Federal Health Insurance Portability and Accountability Act (HIPAA) assures the privacy and security of individuals’ identifiable health information. Therefore, the Department deletes the following confidential data from the UB files provided to the public:
An agreement for release of non-confidential data is required for UB files released to the public.
- Admission and discharge dates
- Patient control and medical record numbers (assigned by hospitals)
- Date of birth
- Patient name
- Patient address
- Insurance and other personal identification numbers
- Attending and other physician codes
- Procedure Dates
The Dept. of Health and Senior Services, Division of Health Care Quality Assessment provides hospital discharge data for the current and ten prior years.
- Statewide summary reports are available through the web. (See link to UB Data Documentation below.) These reports summarize UB data case counts, charges, length of stay and averages by payer and by Diagnosis Related Group using the most current and complete, calendar-year UB data. Statewide reports are available by year through the website, Inpatient Acute Care Hospital Statistics.
- Non-Confidential Patient-level data files are available on request. Requests for patient-level data files require the following:

Please be advised that the New Jersey discharge extract files are derived from hospital uniform billing information. The UB is used to electronically submit claims for health care provided in an institutional setting to payers and to exchange claim information between payers. Variables contained in these files that are not required for claim processing should be used with caution. This includes, but is not limited to, patient race, Hispanic ethnicity, marital status, primary language spoken and residence code. Users should verify conclusions with others data sources.
The Non-Confidential New Jersey hospital discharge data are also available through the Healthcare Cost and Utilization Project (HCUP), a joint federal and state partnership. Users may obtain different state’s discharge data in a standard format. Please see http://www.hcup-us.ahrq.gov .
