Osseous obstruction of Eustachian tube, bilateral

This code describes a condition where the Eustachian tubes in both ears are blocked due to an abnormal growth or formation of bone. This osseous obstruction prevents proper ventilation and drainage of the middle ear, leading to symptoms such as hearing loss, ear fullness, and recurrent ear infections.

This code is appropriate when documentation specifies a bilateral osseous obstruction of the Eustachian tube. This diagnosis is typically made based on imaging studies (e.g., CT scan) that visualize bone growth within or around the Eustachian tube, often in conjunction with clinical findings of Eustachian tube dysfunction.

• Ensure documentation explicitly states "osseous" obstruction and "bilateral" involvement.
• Distinguish from other forms of Eustachian tube obstruction, such as cartilaginous or inflammatory, which would be coded differently.
• Consider co-occurring conditions like otitis media or hearing loss, and code them separately if present and clinically significant.
