H75: Other disorders of middle ear and mastoid in diseases classified elsewhere

The H75 category of the ICD-10 WHO 2016 classification represents specific disorders associated with the middle ear and mastoid, where these disorders are secondary, i.e. occurring as a consequence of other diseases classified elsewhere. The middle ear and mastoid are parts of the ear important for hearing and balance. Disorders in these regions could involve various problems such as inflammation, discharge, pain, hearing loss, or balance issues. The exact symptoms and progression of these disorders can differ, largely depending on the underlying disease causing the disorder. A wide array of diseases – from respiratory tract infections to systemic diseases like diabetes - can potentially affect these parts of the ear, resulting in these secondary middle ear and mastoid disorders. These conditions are not contagious, since they result from the individual's primary disease or condition.
