XIX: Injury, poisoning and certain other consequences of external causes
T66-T78: Other and unspecified effects of external causes
The group of conditions classified under 'Other and unspecified effects of external causes' refers to a wide spectrum of medical issues and behavioral responses that are a direct result of external factors. These factors can include radiation, extreme temperatures, changes in air pressure, exposure to harmful substances, and mechanical forces among others. Symptoms can vary greatly based on the nature of the external cause and the individual's response to it, but common signs may include skin problems, breathing difficulties, nausea, dizziness, fatigue, altered mental states, or physical injuries. These conditions can affect various systems in the body, like the respiratory, circulatory, or nervous systems. The progression of these conditions can range from acute episodes to chronic health issues, depending on the cause, the individual's health status, and the presence of continued exposure.
