Cholesteatoma of tympanum, right ear

This code signifies the presence of a cholesteatoma, which is an abnormal, non-cancerous skin growth that develops behind the eardrum, specifically located within the tympanic membrane of the right ear. This growth can erode surrounding bone and soft tissue, leading to complications like hearing loss, dizziness, and infection.

Use this code when documentation clearly states a cholesteatoma is present within the tympanum of the right ear. This diagnosis is typically made by an otolaryngologist based on otoscopic examination, imaging studies (e.g., CT scan), and patient history. It is often associated with chronic otitis media or a history of ear surgery.

• Differentiate from cholesteatoma of the attic (H71.2-) or mastoid (H71.3-).
• Ensure laterality is explicitly documented as right ear; otherwise, an unspecified laterality code may be more appropriate.
• Code any associated complications, such as conductive hearing loss (H90.0-), separately.
