ICD-10-CM injury codes are multi-axial. ICD-10-CM injury diagnosis codes provide information on both the body region and the nature of injury. ICD-10-CM external cause codes provide information on both the mechanism and the intent of the injury.
Injury Reporting Frameworks, also sometimes referred to as matrices, have been developed to standardize the reporting of injuries by body region/nature of injury or by mechanism/intent of injury. In these Reporting Frameworks, each injury code is placed into one specific grouping or cell of the matrix. This placement is independent of case selection and analysis methods. The matrices define groupings of codes, serve as standardized reference points and are a foundation upon which case selection and injury analysis can be built.
CSTE Injury Policy Briefs endorsing these reports will be posted here as they are approved for publication.
