Cholesteatoma of attic, right ear

This diagnosis code signifies the presence of a cholesteatoma, which is an abnormal, noncancerous skin growth, specifically located in the attic (epitympanum) of the right middle ear. This growth can erode surrounding bone and lead to complications like hearing loss, infection, and dizziness.

Apply this code when documentation clearly indicates a cholesteatoma confined to the attic region of the right ear. This is typically diagnosed via otoscopy, imaging (CT scan), and confirmed during surgical exploration. Supporting documentation should specify the ear affected and the exact location within the middle ear.

• Ensure documentation specifies "attic" or "epitympanum" to differentiate from other cholesteatoma locations.
• Verify laterality (right ear) is clearly stated in the physician's notes.
• Do not use this code for congenital cholesteatomas or cholesteatomas of the mastoid or other middle ear sites.
