About the condition

Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.

Adenoids

Adenoids are a patch of tissue that is high up in the throat, just behind the nose. They, along with the tonsils, are part of the lymphatic system. The lymphatic system clears away infection and keeps body fluids in balance. The adenoids and tonsils work by trapping germs coming in through the mouth and nose.

Code history
