Abnormal auditory function study

This code indicates an abnormal result from an auditory function study, such as an audiogram, otoacoustic emissions (OAEs), or auditory brainstem response (ABR) test. It signifies that the patient's hearing or auditory pathway function deviates from normal parameters, requiring further investigation or management.

Use this code when the documentation explicitly states an abnormal finding from any objective or subjective test designed to assess auditory function. This typically applies when a patient presents with hearing concerns, and diagnostic testing reveals a non-specific abnormality without a definitive diagnosis yet established.

• Do not use this code as a primary diagnosis if a more specific diagnosis for the hearing abnormality (e.g., sensorineural hearing loss, conductive hearing loss) is known and documented.
• This code is often used as a secondary diagnosis when the underlying cause of the abnormal study is being investigated.
• Ensure the medical record clearly specifies which auditory function study was performed and that its results were indeed abnormal.
