Other specified hearing loss, left ear

This code signifies a type of hearing impairment affecting the left ear that does not fit into more specific categories of hearing loss, such as conductive, sensorineural, or mixed, but is clearly identified as something other than normal hearing. It indicates a documented hearing deficit in the left ear with a known, but less common or precisely defined, etiology.

Use this code when medical record documentation specifies a hearing loss in the left ear that is not otherwise classifiable by a more specific ICD-10-CM code. This applies to cases where audiometric testing confirms a left-sided hearing deficit, and the physician's diagnosis indicates a "specified" but "other" type of hearing loss.

• Ensure documentation clearly specifies the left ear. If bilateral or unspecified, a different code is required.
• Avoid using this code if a more specific type of hearing loss (e.g., conductive, sensorineural, mixed) is documented for the left ear.
• Always sequence this code after any underlying cause of the hearing loss, if known and documented.
