Code Description

ICD-10 H66.2 is a billable code used to indicate a diagnosis of chronic atticoantral suppurative otitis media.

Key Diagnostic Point:

Chronic atticoantral suppurative otitis media is a persistent inflammatory condition of the middle ear characterized by the presence of pus and the involvement of the attic and antrum regions of the temporal bone. This condition often arises from recurrent acute otitis media or can be a result of eustachian tube dysfunction, leading to chronic infection and inflammation. Patients typically present with symptoms such as ear pain, hearing loss, and discharge from the ear, which may be foul-smelling. The condition can lead to complications such as cholesteatoma, mastoiditis, and hearing impairment if left untreated. Diagnosis is primarily clinical, supported by otoscopic examination revealing perforation of the tympanic membrane and purulent discharge. Imaging studies, such as CT scans, may be utilized to assess the extent of disease and rule out complications. Management often involves medical treatment with antibiotics and, in many cases, surgical intervention such as tympanomastoid surgery to remove infected tissue and restore hearing.
