H60.552 Acute reactive otitis externa, left ear

Name of the Condition

• Acute reactive otitis externa, left ear

Summary

Acute reactive otitis externa, left ear, is an inflammation of the external ear canal on the left side resulting from a reactive process. It typically causes localized discomfort and may involve skin changes in the ear canal.

Causes

The condition is primarily caused by noninfectious reactions to external factors, such as irritants, allergens, or mechanical trauma. Common triggers include exposure to chemicals, foreign objects, or environmental substances that provoke an inflammatory response in the ear canal.

Risk Factors

• Exposure to irritants (e.g., soaps, shampoos, or ear drops)
• Allergic reactions to substances like jewelry or hearing aid materials
• Trauma from inserting objects into the ear
• Prolonged use of earbuds or hearing aids
• Environmental irritants (e.g., dust, smoke)

Symptoms

• Itching or irritation in the ear canal
• Pain or discomfort, often worsening with movement
• Redness and swelling of the ear canal
• Possible flaking or scaling of the skin
• Sensation of fullness in the ear

Diagnosis

Diagnosis is typically made through a physical examination of the ear canal using an otoscope. A healthcare provider may assess for redness, swelling, or signs of irritation. Cultures are usually not performed unless infection is suspected.

Treatment Options

• Avoidance of known irritants or allergens
• Topical corticosteroids to reduce inflammation
• Pain management with over-the-counter analgesics
• Ear canal cleaning (if debris is present)
• Referral to an otolaryngologist for severe or persistent cases

Prognosis and Follow-Up

Most cases resolve with appropriate treatment and avoidance of triggers. Follow-up may be recommended to ensure symptoms improve and to address any underlying causes. Recurrence is possible if irritants or allergens are not avoided.

Complications

• Chronic otitis externa if triggers persist
• Secondary infection if the skin barrier is compromised
• Hearing impairment due to swelling or debris blocking the ear canal

Lifestyle & Prevention

• Avoid inserting objects into the ear
• Use hypoallergenic ear products
• Protect the ear from water during bathing or swimming
• Limit exposure to known irritants or allergens
• Maintain good ear hygiene without overcleaning

When to Seek Professional Help

Seek care if symptoms worsen, persist beyond a few days, or are accompanied by fever, severe pain, or discharge. Prompt evaluation is important if hearing changes or signs of infection develop.

Tips for Medical Coders

Document the laterality (left ear) and confirm the condition is acute and reactive (noninfective) to support accurate coding. Ensure clinical documentation specifies the affected ear and the reactive nature of the otitis externa to align with the code H60.552.
