The Healthcare Cost and Utilization Project (HCUP) released a new database: 2016 National Inpatient Sample (NIS). The NIS is the largest publicly available all-payer inpatient care database in the United States. The 2016 NIS is an annual, calendar year file with diagnosis and procedure codes reported using only the ICD-10-CM/PCS coding system. The file structure of the 2016 NIS is similar to the file structure of the NIS in data years prior to 2015 with one exception, data elements derived from AHRQ software tools are not available in the 2016 NIS because the ICD-10-CM/PCS versions are still under development.
HCUP nationwide and State-level HCUP databases (including the 2016 NIS) are available for purchase through the HCUP Central Distributor. Applications are available at: www.hcup-us.ahrq.gov/tech_assist/centdist.jsp
