Use a child code to capture more detail.ICD Code H70 is a non-billable code.

The ICD code H70 is used to code Mastoiditis
Mastoiditis is the result of an infection that extends to the air cells of the skull behind the ear. Specifically, it is an inflammation of the mucosal lining of the mastoid antrum and mastoid air cell system inside the mastoid process. The mastoid process is the portion of the temporal bone of the skull that is behind the ear which contains open, air-containing spaces. Mastoiditis is usually caused by untreated acute otitis media (middle ear infection) and used to be a leading cause of child mortality. With the development of antibiotics, however, mastoiditis has become quite rare in developed countries where surgical treatment is now much less frequent and more conservative, unlike former times. Additionally, there is no evidence that the drop in antibiotic prescribing for otitis media has increased the incidence of mastoiditis. Untreated, the infection can spread to surrounding structures, including the brain, causing serious complications.
