Otitis Externa ICD-10-CM Codes

Otitis externa is often caused by water exposure, which can create a moist environment in the ear canal, making it susceptible to infection. It can also result from scratches or irritation of the ear canal, as well as the use of objects like cotton swabs that can damage the ear canal lining.

Otitis externa itself is not contagious, but the infection causing it can be spread if an infected person's ear drainage comes into contact with another person's ears. Practicing good hygiene and avoiding sharing personal items is essential to prevent transmission.

Otitis externa can often be prevented by keeping the ears dry, avoiding inserting objects into the ear canal, and practicing good ear hygiene. Using earplugs when swimming and promptly drying the ears after water exposure can also help reduce the risk.
