    External causes of morbidity

    • This chapter permits the classification of environmental events and circumstances as the cause of injury, and other adverse effects. Where a code from this section is applicable, it is intended that it shall be used secondary to a code from another chapter of the Classification indicating the nature of the condition. Most often, the condition will be classifiable to Chapter 19, Injury, poisoning and certain other consequences of external causes (S00-T88). Other conditions that may be stated to be due to external causes are classified in Chapters I to XVIII. For these conditions, codes from Chapter 20 should be used to provide additional information as to the cause of the condition.

Clinical Information
  • A fall can change your life. If you're elderly, it can lead to disability and a loss of independence. If your bones are fragile from osteoporosis, you could break a bone, often a hip. But aging alone doesn't make people fall. Diabetes and heart disease affect balance. So do problems with circulation, thyroid or nervous systems. Some medicines make people dizzy. Eye problems or alcohol can be factors. Any of these things can make a fall more likely. Babies and young children are also at risk of falling - off of furniture and down stairs, for example.falls and accidents seldom "just happen." taking care of your health by exercising and getting regular eye exams and physicals may help reduce your chance of falling. Getting rid of tripping hazards in your home and wearing nonskid shoes may also help. To reduce the chances of breaking a bone if you do fall, make sure that you get enough calcium and vitamin d. nih: national institute on aging
