H60.333 Swimmer's ear, bilateral

Name of the Condition

• Swimmer's ear, bilateral. This refers to an inflammation of the external ear canal affecting both ears, often caused by prolonged water exposure, leading to infection or irritation.

Summary

Swimmer's ear is an inflammation of the external ear canal, typically resulting from moisture retention or infection. It commonly causes localized discomfort, pain, and possible discharge. The condition is treatable with medical interventions targeting the underlying cause.

Causes

The condition is primarily caused by bacterial or fungal infections, which thrive in moist environments. Prolonged water exposure, such as from swimming, can trap water in the ear canal, creating a breeding ground for microbes. Trauma to the ear canal, like from inserting objects or aggressive cleaning, may disrupt the skin barrier and facilitate infection.

Risk Factors

• Spending extended periods in water (swimming).
• Excessive moisture in the ear from humidity or sweat.
• Aggressive cleaning of the ear canal with cotton swabs or foreign objects.
• Chronic skin conditions such as eczema or psoriasis.
• Wearing hearing aids or earbuds for prolonged periods.

Symptoms

• Itching in the ear canal.
• Redness inside the ear.
• Discomfort or pain, especially when pulling on the ear or chewing.
• Fluid drainage from the ear.
• Reduced hearing or a feeling of fullness in the ear.

Diagnosis

Diagnosis involves a physical examination of the ear canal, often using an otoscope to assess redness, swelling, or discharge. A healthcare provider may also inquire about recent water exposure or trauma. In some cases, a sample of ear discharge may be collected for laboratory testing to identify the causative organism.

Treatment Options

Treatment typically includes ear drops containing antibiotics or antifungals to address infection, along with measures to dry the ear canal. Pain relief medications may be recommended for discomfort. Severe cases or those with significant swelling might require a healthcare provider to clean the ear canal or place a wick to deliver medication.

Prognosis and Follow-Up

With appropriate treatment, most cases resolve within 1–2 weeks. Follow-up may be necessary to ensure the infection has cleared and to address any persistent symptoms. Recurrence is possible if risk factors, such as water exposure, are not managed.

Complications

Untreated or severe cases can lead to deeper tissue infection, temporary hearing loss, or cellulitis. Rarely, the infection may spread to surrounding structures, requiring more intensive treatment.

Lifestyle & Prevention

• Keep ears dry after swimming or bathing, using earplugs or a towel.
• Avoid inserting objects into the ear canal.
• Use over-the-counter drying ear drops after water exposure.
• Maintain good ear hygiene without aggressive cleaning.

When to Seek Professional Help

Seek care if symptoms worsen, persist beyond a few days, or include severe pain, fever, or discharge with a foul odor. These may indicate a more serious infection requiring prompt evaluation.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record, as this distinguishes it from unilateral swimmer's ear. Ensure the diagnosis aligns with clinical findings, such as bilateral ear canal inflammation or infection. Code H60.333 is specific to bilateral involvement and should be used when both ears are affected.
