Y85-Y89: Sequelae of external causes of morbidity and mortality

The term "Sequelae of external causes of morbidity and mortality" refers to the long-term effects or complications that follow a previous injury, poisoning, or other adverse event. These sequelae can occur any time after the incident, even years later, and they tend to vary widely based on the nature, severity, and location of the original event. They can affect any part of the body and can manifest in numerous ways. For instance, an individual who has suffered a severe head injury might later experience seizures or cognitive issues as a sequelae. Another person who has survived a serious poisoning event might later show signs of organ damage. Some common sequelae include pain, physical disabilities, cognitive impairments, and mental health conditions. How these sequelae present and progress can differ greatly from person to person. Typically, they are the result of residual damage from the original event that did not fully heal or that caused permanent changes to the affected area or system.
