CPT® Code 69806

An endolymphatic sac operation is a surgical procedure aimed at addressing Meniere's disease, a condition characterized by episodes of vertigo, fluctuating hearing loss, tinnitus, and a sensation of fullness in the ear. This operation can be performed with or without the placement of a shunt. The procedure involves accessing the mastoid bone, which is located behind the ear, to reach the endolymphatic sac, a structure within the inner ear that plays a crucial role in maintaining balance and hearing. During the operation, the mastoid bone is surgically opened to allow for better visualization and access to the endolymphatic sac. In the context of CPT® Code 69806, the procedure specifically includes the insertion of a shunt. This shunt is designed to facilitate the drainage of excess fluid from the endolymphatic sac, thereby alleviating the pressure that contributes to the symptoms of Meniere's disease. The shunt is equipped with a one-way valve, which permits fluid to escape from the sac while preventing any backflow, thus helping to manage the fluid dynamics within the inner ear effectively.
