Oth disrd of middle ear and mastoid, bilateral

This code signifies a bilateral presentation of various non-otitis media, non-cholesteatoma, and non-perforation conditions affecting the middle ear and mastoid. These can include issues like tympanosclerosis, adhesive otitis, or other structural abnormalities not classified elsewhere. It indicates that both ears are affected by such a disorder.

Apply this code when documentation specifies a bilateral middle ear or mastoid disorder that doesn't fit more specific codes for otitis media, cholesteatoma, or tympanic membrane perforation. Examples include bilateral tympanosclerosis or bilateral adhesive otitis. Ensure the medical record clearly states the condition affects both ears.

• Do not use this code if a more specific bilateral code exists for the documented condition (e.g., bilateral acute otitis media).
• Always review documentation for laterality. If only one ear is affected, use the appropriate unilateral code (H74.8X1 or H74.8X2).
• Ensure the specific "other specified disorder" is clearly documented to support the use of this "other specified" category.
