About the condition
Plain-language background from MedlinePlus (National Library of Medicine), not coding guidance.
Drowning
People drown when they get too much water in their lungs. You can drown in as little as an inch or two of water. Babies can drown in a sink or bathtub. Preschoolers are most likely to drown in a swimming pool. People who have seizure disorders are also at risk in the water. Drowning can happen quickly and silently.
