U49.9: Emergency use of U49.9

The ICD-10 code U49.9 pertains to a situation where provisional use of new medical conditions or disorders are in effect. These new diseases or conditions may still be under investigation, and their symptoms, causes, and progression may not be fully understood. While they do not have a specific designated code under the standard International Classification of Diseases (ICD) system, these conditions are registered under this code for the purpose of data collection, investigation, and research. As these conditions can widely vary, it is not possible to provide a uniform description of symptoms or disease progression. Their identification and categorization under this code is due to a global health need or emergency where response cannot wait for the next ICD-10 update.
