Final answer:
In ICD-10, injuries related to poisonings are categorized in Chapter 20 under codes for external causes of morbidity and mortality, specifically under categories such as accidental poisonings (codes X40–X49).
Step-by-step explanation:
In the International Classification of Diseases (ICD-10), Chapter 20 covers External Causes of Morbidity and Mortality, which includes external factors that contribute to injuries or health conditions, such as poisonings and accidents. The options given in the question (E codes and V codes) correspond to the older ICD-9 system, in which 'E' codes were used for external causes of injury and 'V' codes represented supplementary factors influencing health status. In ICD-10, these have been restructured, with poisoning, for example, found in various chapters depending on the context, but external causes are now categorized in Chapter 20 under the letter 'V' for transport accidents, 'W' for other accidents, 'X' for accidents caused by natural and environmental factors, and 'Y' for other external causes. Injuries related to poisonings would indeed be found within these external cause codes of ICD-10, specifically under categories like accidental poisonings (codes X40–X49).
