Cholesteatoma of attic, left ear

This code represents a cholesteatoma, which is an abnormal, noncancerous skin growth that develops in the middle ear behind the eardrum. Specifically, this code indicates the cholesteatoma is located in the attic (epitympanum) of the left ear. This growth can erode surrounding bone and lead to hearing loss and other complications.

Use this code when documentation clearly identifies a cholesteatoma located in the attic of the left ear. This diagnosis is typically made by an otolaryngologist based on otoscopic examination, imaging studies (e.g., CT scan), and sometimes surgical findings. Supporting documentation should specify the ear affected and the precise location within the middle ear.

• Always specify laterality (left, right, bilateral) when documented.
• Differentiate from other types of cholesteatoma based on location (e.g., mastoid, middle ear without further specification).
• Ensure the documentation explicitly states "attic" or "epitympanum" for accurate coding to this specific subcategory.
