Acustc neuritis in infec/parastc dis classd elswhr, r ear

This code signifies inflammation of the auditory nerve (acoustic neuritis) affecting the right ear, specifically when it arises as a manifestation or complication of an underlying infectious or parasitic disease. This condition typically presents with sudden or progressive hearing loss, tinnitus, and/or vertigo. The "classified elsewhere" designation indicates that the primary infectious or parasitic disease should be coded first.

Apply this code when documentation clearly states acoustic neuritis of the right ear is secondary to an infection or parasitic infestation, such as Lyme disease, syphilis, mumps, or HIV. The medical record must explicitly link the acoustic neuritis to the infectious or parasitic etiology.

• Always sequence the underlying infectious or parasitic disease code first, followed by this code.
• Ensure documentation specifies "right ear" to support laterality.
• Do not use this code for acoustic neuritis of unknown etiology or due to non-infectious causes.
