Sudden hearing loss, unspecified

This code signifies an acute, rapid onset of hearing impairment in one or both ears, where the underlying cause has not yet been determined or specified. It represents a sudden sensorineural hearing loss (SSNHL) without further diagnostic clarity regarding its etiology.

Apply this code when documentation indicates a patient presents with sudden hearing loss, and the physician's assessment does not specify the type (e.g., conductive, sensorineural) or the underlying cause. It is appropriate for initial encounters where the diagnosis is still pending further investigation.

• Avoid using this code if the documentation specifies the type or cause of sudden hearing loss; instead, select a more specific code.
• This code is often temporary, used until a definitive diagnosis can be established through further testing or specialist consultation.
• Ensure the medical record clearly states "sudden" or "acute" onset of hearing loss to support this code.
