This web page summarizes key issues for researchers using HCUP and other administrative databases that include International Classification of Diseases, 10th Revision, Clinical Modification/Procedure Coding System (ICD-10-CM/PCS) coding. The page documents key differences in the structure of HCUP databases, provides general guidance to users analyzing outcomes that may be affected by the transition to the ICD-10-CM/PCS coding system, and lists other related resources.
In October 2015, the United States transitioned to the ICD-10-CM diagnosis coding system for most inpatient and outpatient medical encounters and the ICD-10-PCS procedure coding system for inpatient hospital procedures. This transition had a direct impact on the reporting of medical services and health services research.
