ICD11DSM5

ICD11DSM5 is a term used to describe the relationship and alignment between the World Health Organization’s ICD-11 classification of diseases and the American Psychiatric Association’s DSM-5 diagnostic system in mental health care. It denotes efforts to map diagnoses and codes between these two widely used classification frameworks, to support communication, coding, and research across different health systems.

ICD-11, published by the WHO, provides a global system for coding diseases and health conditions, including mental disorders, with an emphasis on international comparability and public health statistics. DSM-5, developed by the APA, offers criteria-based diagnoses used primarily in clinical practice and research in the United States. Because the two systems have distinct structures, categories, and criteria, a direct one-to-one translation is not always possible. Mapping efforts aim to identify corresponding entities, create crosswalks, and facilitate data interpretation and interoperability.

Applications of ICD11DSM5 mappings include facilitating epidemiological studies, enabling more consistent medical record-keeping, supporting multi-system billing and reimbursement, and aiding international collaborations where both codes are used. They can also assist in education and training by clarifying how disorders are categorized across different frameworks. However, limitations are acknowledged: some DSM-5 disorders may correspond to multiple ICD-11 diagnoses, and some criteria distinctions may not align perfectly. Updates to either system require revision of crosswalks to maintain accuracy.
