ICD-10-CM Transition 

Effective October 1, 2015, the U.S. Department of Health and Human Services required health care organizations and providers covered by the Health Insurance Portability and Accountability Act (HIPAA), to use ICD‐10‐CM to report medical encounters when submitting electronic claims for administrative and financial transactions. Prior to October 1, 2015, the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD‐9‐CM) was used for coding medical encounters in the hospital setting, including hospitalizations, ED visits, or outpatient offices. The major transition from ICD‐9‐CM to ICD‐10‐CM has affected local, state, and national activities that use electronic claims files from hospitalizations and ED visits to conduct injury and violence surveillance. It is important that jurisdictions consider the impact that this transition in coding will have on any trend analyses that span this time period. Given the significant changes in ICD-9-CM and ICD-10-CM, it is recommended to include a break in data when presenting trend analysis that spans this transitional time.
