Extrinsic cartilagenous obst of eustach tube, right ear

This code signifies a blockage of the right Eustachian tube caused by external cartilage pressing on it, rather than an internal issue within the tube itself. This obstruction can lead to symptoms such as ear fullness, hearing loss, or recurrent ear infections due to impaired middle ear ventilation.

Apply this code when documentation clearly indicates an extrinsic cartilaginous cause for Eustachian tube dysfunction affecting the right ear. This is typically diagnosed by an otolaryngologist based on otoscopic findings, tympanometry, and patient history. The physician's notes should specify the laterality and the external cartilaginous nature of the obstruction.

• Ensure the documentation explicitly states "right ear" and specifies an "extrinsic cartilaginous" cause.
• Do not confuse with intrinsic obstructions (e.g., H68.03- series) or other types of Eustachian tube dysfunction without a specified obstruction.
• Consider co-reporting with codes for associated symptoms (e.g., conductive hearing loss, otitis media) if documented.
