Diplacusis, left ear

This code signifies a condition where the left ear perceives a single sound as two distinct pitches or tones. It represents a form of auditory distortion, specifically a pitch-related dysacusis, affecting only the left ear.

Apply this code when documentation clearly indicates diplacusis localized to the patient's left ear. This diagnosis is typically made by an audiologist or otolaryngologist based on patient report and audiological testing confirming the perception of different pitches for the same sound in the left ear.

• Ensure documentation specifies "left ear" to differentiate from bilateral or right ear involvement.
• Do not confuse with tinnitus, which is the perception of sound without an external source, or hyperacusis, which is an increased sensitivity to sound.
• Consider sequencing with underlying conditions contributing to the diplacusis, such as Meniere's disease or sudden sensorineural hearing loss, if documented.
