Otitis externa is a condition that causes inflammation (redness and swelling) of the external ear canal, which is the tube between the outer ear and eardrum. Otitis externa is often referred to as "swimmer's ear" because repeated exposure to water can make the ear canal more vulnerable to inflammation.Jul 6, 2021
2022 ICD-10-CM Diagnosis Code H65. 93: Unspecified nonsuppurative otitis media, bilateral.
Unilateral otitis externa may suggest the presence of an underlying foreign body or neoplasia, although bilateral involvement with these causes is possible, and unilateral involvement can occur with symmetric disorders such as allergic dermatitis and ceruminous gland hyperplasia.
The condition of otitis externa, often called "Swimmers ear", differs from otitis media, although both may be present simultaneously.Mar 7, 2021
Other infective otitis externa, unspecified ear H60. 399 is a billable/specific ICD-10-CM code that can be used to indicate a diagnosis for reimbursement purposes.

Diagnosis. Acute otitis externa is diagnosed clinically based on signs and symptoms of canal inflammation (Table 24; Figures 1 and 2). Presentation can range from mild discomfort, itching, and minimal edema to severe pain, complete canal obstruction, and involvement of the pinna and surrounding skin.Dec 1, 2012
Bilateral acute otitis media (AOM) is considered more severe than unilateral AOM, and several guidelines recommend more active management of bilateral AOM. However, severity of symptoms and otoscopic signs of bilateral and unilateral AOM have previously not been comprehensively studied.Feb 1, 2013
Systemic diseases that may cause otitis externa include atopic dermatitis, psoriasis, seborrheic dermatitis, acne and lupus erythematosus. Lesions typically occur in the external auditory canal and elsewhere on the body, especially the head and neck.Mar 1, 2001
Otitis means inflammation of the ear. The inflammation is usually due to an infection. Otitis externa means that the inflammation is confined to the external part of the ear canal and does not go further than the eardrum. See separate leaflet called Ear Infection (Otitis Media), for an infection of the middle ear.Oct 19, 2016
Chronic otitis externa is caused by irritation from drainage through a perforated tympanic membrane. The underlying cause is chronic suppurative otitis media. Itching may be severe.
The position of the tympanic membrane is a key for differentiating acute otitis media and otitis media with effusion. In acute otitis media, the tympanic membrane is usually bulging. In otitis media with effusion, it is typically retracted or in the neutral position.Apr 1, 2000
