Polyp of middle ear, bilateral

This code signifies the presence of a benign, often inflammatory, growth originating from the mucosal lining of the middle ear cavity in both ears. These polyps can obstruct the Eustachian tube or fill the middle ear space, potentially leading to conductive hearing loss or recurrent otitis media.

Apply this code when documentation explicitly states "bilateral middle ear polyp" or "polyp of middle ear, both ears." This diagnosis is typically made via otoscopy, tympanometry, or surgical exploration (e.g., myringotomy with middle ear exploration).

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code (H74.41 or H74.42).
• Do not confuse with polyps of the external ear canal (H61.0-) or nasal polyps (J33.-).
• If the polyp is a sequela of chronic otitis media, consider sequencing the chronic otitis media code first, if appropriate per coding guidelines.
