Discontinuity and dislocation of right ear ossicles

This code signifies a structural disruption in the small bones (malleus, incus, stapes) of the right middle ear, leading to their separation or displacement. This discontinuity impairs the normal transmission of sound vibrations from the eardrum to the inner ear, typically resulting in conductive hearing loss.

Apply this code when documentation explicitly states a discontinuity or dislocation of the ossicles in the right ear. This often occurs due to trauma, chronic otitis media, or cholesteatoma. Supporting documentation should include operative reports detailing ossicular chain disruption or imaging findings confirming the dislocation.

• Specify laterality: Ensure the documentation clearly indicates the right ear. If left or bilateral, a different code is required.
• Distinguish from other ossicular disorders: Do not confuse with fixation (H74.22-) or partial destruction (H74.23-).
• Sequence appropriately: If an underlying cause (e.g., trauma, chronic otitis media) is identified, code it as the primary diagnosis if it led to the ossicular discontinuity.
