CPT® Code 69662

The procedure described by CPT® Code 69662 refers to the revision of a stapedectomy or stapedotomy, which are surgical interventions aimed at addressing issues related to the stapes bone in the middle ear. The stapes, one of the three ossicles, plays a crucial role in the auditory system by transmitting sound vibrations from the outer ear to the inner ear. In cases where the stapes becomes fixed due to a condition known as otosclerosis, patients experience conductive hearing loss. This fixation occurs when abnormal bone growth affects the stapes, preventing it from vibrating freely. The revision procedure is necessary when a previous stapedectomy or stapedotomy has not yielded the desired results or when complications arise, such as a broken or dislodged prosthesis. During the surgery, the surgeon makes an incision in the posterior ear canal wall to access the middle ear, elevating a tympanomeatal flap to expose the ossicles. The surgeon then assesses the condition of the stapes and determines the appropriate course of action, which may involve replacing a faulty prosthesis or removing part of the stapes to insert a complete prosthesis. The procedure concludes with the repair of any defects in the oval window and the closure of the incision, ensuring that the auditory pathway is restored for optimal hearing function.
