Polyp of left middle ear

This code signifies the presence of an abnormal growth, specifically a polyp, located within the left middle ear cavity. These benign lesions can arise from chronic inflammation or infection within the middle ear.

Use this code when documentation clearly indicates a polyp originating in the left middle ear. This diagnosis is typically made via otoscopy, imaging (CT scan), or during surgical exploration. Supporting documentation should specify the laterality and location of the polyp.

• Ensure laterality (left ear) is explicitly documented; do not assume.
• Distinguish from polyps of the external ear canal or nasal polyps which have different codes.
• Code any underlying conditions, such as chronic otitis media, as additional diagnoses.
