Osseous obstruction of Eustachian tube, unspecified ear

This code signifies a blockage of the Eustachian tube caused by abnormal bone growth or formation, affecting an unspecified ear. This obstruction can lead to impaired middle ear ventilation and drainage, potentially resulting in conductive hearing loss, otitis media, or aural fullness.

Assign this code when medical record documentation clearly indicates an osseous (bony) obstruction of the Eustachian tube, and the specific ear affected (left or right) is not documented. Supporting documentation would include imaging reports (e.g., CT scan) or surgical findings detailing the bony nature of the obstruction.

• Ensure the documentation explicitly states "osseous" or "bony" obstruction; do not assume based on other types of obstruction.
• If the affected ear is specified (left or right), use the more specific codes H68.111 or H68.112.
• This code is for the obstruction itself, not the resulting conditions like otitis media, which would be coded separately.
