T90-T98: Sequelae of injuries, of poisoning and of other consequences of external causes
T98: Sequelae of other and unspecified effects of external causes
Sequelae of other and unspecified effects of external causes, also known as aftermath or late effects, relate to conditions that occur as a direct result of an injury, accident, or other trauma that has occurred in the past. These can develop days, months, or even years after the initial event. This group of conditions covers a vast array of symptoms and complications that are not immediate but still connected to a prior incident. The effects can appear in any system of the body and vary widely depending on the specific circumstances of each individual. They do not have a uniform progression and may evolve over time. Some examples might include chronic pain following a healed physical injury, cognitive issues after a traumatic brain injury, or psychological problems such as post-traumatic stress disorder after a severe accident. The causes, symptoms, and overall impact of these sequelae can vary greatly, making each individual's experience unique.
