Proposed Framework for Presenting Injury Data Using the International Classification of Diseases, Tenth Revision, Clinical Modification (ICD-10-CM) Diagnosis Codes.
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.
