Cholesteatoma of right external ear

This code describes a non-cancerous, cyst-like growth of skin cells and keratin debris located within the right external auditory canal. This condition can lead to local bone erosion, infection, and hearing loss if left untreated.

Assign this code when documentation specifies a cholesteatoma confined to the external ear canal on the right side. This diagnosis is typically made upon otoscopic examination revealing a pearly mass or keratin debris within the canal, often accompanied by symptoms like otorrhea, otalgia, or hearing impairment.

• Differentiate from middle ear cholesteatoma (H71.-), which is a distinct and more serious condition.
• Ensure laterality is clearly documented (right, left, or bilateral) to select the most specific code.
• Look for documentation of associated complications, such as infection or bone erosion, which may require additional codes.
