T15-T19: Effects of foreign body entering through natural orifice

The conditions classified between T15-T19 refer to the effects of a foreign body entering the body through a natural orifice. These conditions occur when an object from outside the body makes its way into the body through an opening such as the mouth, nose, or ears, or less commonly, other orifices. The foreign bodies can be a variety of substances or items such as food, small toys, insects, or even chemicals. Common symptoms can include pain, swelling, and signs of infection like fever or redness. In some instances, a foreign body may cause no symptoms at all but may still lead to complications over time. Symptoms can vary based on the place the foreign body entered and the nature of the foreign object. Disease progression can range from minor discomfort to serious conditions if the foreign body obstructs a passage or causes damage. Many body systems can be affected, including the respiratory system or the gastrointestinal tract, based on the entry point of the foreign body.
