Cholesteatoma of attic, bilateral

This code describes a non-cancerous, cyst-like growth of skin cells that develops in the attic (epitympanum) of both middle ears. This condition can erode surrounding bone and lead to hearing loss, dizziness, and chronic ear infections. It is an acquired form of cholesteatoma, distinct from congenital types.

Use this code when documentation clearly indicates a diagnosis of cholesteatoma located specifically in the attic region of both ears. This diagnosis is typically made by an otolaryngologist based on otoscopic examination, imaging studies (e.g., CT scan), and sometimes surgical findings.

• Differentiate from cholesteatoma of other ear regions (e.g., mastoid, middle ear) and unilateral involvement.
• Ensure the documentation specifies "attic" and "bilateral" for accurate code assignment.
• Consider sequencing with codes for associated complications like conductive hearing loss (H90.0) or chronic otitis media (H66.9-).
