Chronic atticoantral suppurative otitis media, bilateral

This code signifies a persistent, purulent infection affecting both the attic (epitympanum) and antrum of the middle ear. It is characterized by chronic inflammation, often with cholesteatoma formation, and involves both ears.

Use this code when documentation explicitly states bilateral chronic atticoantral suppurative otitis media. This diagnosis is typically supported by otoscopic findings, audiometry, and imaging (e.g., CT scan) demonstrating chronic inflammation and/or cholesteatoma in both middle ears.

• Ensure documentation specifies "bilateral" involvement; otherwise, use the appropriate unilateral code.
• Distinguish from chronic tubotympanic suppurative otitis media, which involves a different part of the middle ear.
• Look for associated conditions like cholesteatoma, which may require additional coding.
