H66.20
ICD-10-CMChronic atticoantral suppurative otitis media, unspecified ear
This code signifies a persistent, purulent infection of the middle ear involving the attic (epitympanum) and antrum, characterized by chronic inflammation and often bone erosion. It represents a long-standing inflammatory process within these specific middle ear structures, typically associated with cholesteatoma formation.
Apply this code when documentation explicitly states "chronic atticoantral suppurative otitis media" without specifying laterality. This diagnosis is often made based on otoscopic findings, imaging (e.g., CT scan showing bone erosion or cholesteatoma), and a history of recurrent ear discharge.
