    Coding mechanisms for diagnosis timing in the International Classification of Diseases, Version 11
    (2022-09-16) Sundararajan, Vijaya; Le Pogam, Marie-Annick; Southern, Danielle A.; Pincus, Harold A.; Ghali, William A.
    Abstract Background Diagnoses that arise after admission are of interest because they can represent complications of health care, acute conditions arising de novo, or acute decompensation of a chronic comorbidity occurring during the hospital stay. Three countries in the world have adopted diagnosis timing codes for a number of years. Their experience demonstrates the feasibility and utility of associating an International Classification of Diseases, Version 9 or International Classification of Diseases, Version 10 diagnostic code with information on diagnosis timing, either as part of a diagnostic field or as a separate field. However, diagnosis timing is not an integrated feature of these two classifications as it will be for International Classification of Diseases, Version 11. Methods We examine the different types of diagnosis timing that can be used to describe complex patients and present examples of how the new International Classification of Diseases, Version 11 codes may be used. Results Extension codes are one of the important new features of International Classification of Diseases, Version 11 and allow more specificity in diagnosis timing. Conclusion Imbedded and standardized diagnosis timing information is possible within the International Classification of Diseases, Version 11 classification system.

    The three-part model for coding causes and mechanisms of healthcare-related adverse events
    (2022-02-24) Southern, Danielle A.; Harrison, James E.; Romano, Patrick S.; Le Pogam, Marie-Annick; Pincus, Harold A.; Ghali, William A.
    Abstract ICD-11 provides a promising new way to capture healthcare-related harm or injury. In this paper, we elaborate on the framework for describing healthcare-related events where there is a presumed causal link between an event and underlying healthcare-related factors. The three-part model for describing healthcare-related harm or injury in ICD-11 consists of (1) a healthcare-related activity that is the cause of injury or other harm (selected from Chapter 23 of ICD-11); (2) a mode or mechanism of injury or harm, related to the underlying cause (also from Chapter 23 of ICD-11); and (3) the harmful consequences of the event to the patient, selected from any of Chapters 1 through 22 of ICD-11 (most importantly, the injury or harm experienced by the patient). Concepts from these three elements are linked/clustered through postcoordination to reflect the three-part model in a single coded expression. ICD-11 contains many novel features, and the three-part model described here for healthcare-related adverse events is a notable example.
