Swimmer's ear, right ear

This code represents an infection of the external auditory canal, specifically in the right ear, often associated with water exposure. It is characterized by inflammation, pain, itching, and sometimes discharge, commonly known as otitis externa.

Use this code when documentation clearly indicates a diagnosis of otitis externa affecting the right ear, with the etiology specified as "swimmer's ear" or related to water exposure. Supporting documentation should include physician notes detailing the patient's symptoms, physical examination findings (e.g., canal erythema, edema, discharge), and the confirmed diagnosis.

• Ensure laterality is explicitly documented as "right ear" to support this specific code.
• Distinguish from other forms of otitis externa (e.g., fungal, eczematous) if the etiology is not water-related.
• Do not use if the infection is bilateral or affects only the left ear; separate codes exist for those scenarios.
