Abn results of function studies of ear and oth sp senses

This code signifies abnormal findings from various functional tests related to the ear and other special senses, excluding those specifically covered by other codes in the R94.1x series. It indicates that objective diagnostic studies have revealed a deviation from normal function in these sensory systems, but without a definitive diagnosis yet established.

Use this code when diagnostic tests such as electrocochleography (ECoG), otoacoustic emissions (OAEs), or other specialized sensory function studies (e.g., taste, smell) show abnormal results, and a more specific diagnosis is not yet determined. Documentation should clearly state the abnormal findings from the specific functional study performed.

• Do not use this code if a definitive diagnosis for the abnormal finding has been established; instead, code the specific condition.
• Ensure the medical record explicitly documents the abnormal results of a functional study of the ear or other special senses.
• This code is often used as a primary diagnosis when further investigation is warranted based on initial abnormal test results.
