Proposed Framework for Presenting Injury Data Using the International Classification of Diseases, Tenth Revision,...

Frameworks based on the International Classification of Diseases (ICD) provide injury researchers and epidemiologists with standard approaches for presenting and analyzing injury-related mortality and morbidity data. Injury diagnosis frameworks, such as the Barell Matrix for the ICD Ninth Revision, Clinical Modification (ICD-9-CM) and the Injury Mortality Diagnosis Matrix for the ICD Tenth Revision (ICD-10), categorize ICD codes into major body region (e.g., head, chest, abdomen, or extremity) by nature-of-injury (e.g., fracture, laceration, organ injury, or vascular injury) categories. In the United States, morbidity coding transitioned from ICD-9- CM to ICD-10-CM on October 1, 2015. In preparation for the use of ICD-10-CMcoded morbidity data for injury surveillance and data analysis, the National Center for Health Statistics and the National Center for Injury Prevention and Control propose an ICD-10-CM Injury Diagnosis Matrix to provide a standard approach for categorizing injuries by body region and nature of injury. This report provides a brief description of the differences between ICD-9-CM and ICD-10-CM injury diagnosis codes, introduces the proposed framework and the methods used to create it, and provides a list of additional considerations for review and comment by researchers and subjectmatter experts in injury data and surveillance.
