Other disorders of ear in diseases classified elsewhere (H94)

The ICD-10 code H94 covers other ear disorders linked to diseases classified elsewhere, with specific codes addressing acoustic neuritis and other specified ear conditions based on the affected ear side.

This category is used to code ear problems that occur as part of other illnesses, rather than primary ear diseases. For example, H94.0 and its subcodes (H94.00, H94.01, H94.02, H94.03) specifically identify acoustic neuritis; an inflammation of the acoustic nerve; when caused by infections or parasitic diseases. These subcodes clarify if the condition affects the right ear, left ear, both ears, or is unspecified. The terms “acoustic neuritis due to infectious disease” or simply “acoustic neuritis” can help medical coders associate these symptoms directly with the ICD-10 code H94.0 series. Additionally, there are codes like H94.8 and its subcodes for other specified ear disorders related to systemic diseases, allowing precise documentation when the exact ear condition differs from acoustic neuritis but is still secondary to another underlying disease.
