CPT® Code 69802

The procedure described by CPT® Code 69802 is known as labyrinthotomy with perfusion of vestibuloactive drug(s) and is performed in conjunction with a mastoidectomy. This surgical intervention is primarily indicated for the treatment of Meniere's disease, a condition characterized by episodes of vertigo, hearing loss, tinnitus, and a sensation of fullness in the ear. The labyrinth, which is the inner ear structure, consists of a complex system of canals and cavities that play a crucial role in balance and hearing. It is divided into two main components: the bony labyrinth, which provides structural support, and the membranous labyrinth, which contains the sensory organs. In this procedure, the surgeon accesses the inner ear through a transmastoid approach, which involves making an incision behind the ear to expose the mastoid bone. The mastoidectomy entails the removal of the air cell system within the mastoid bone, allowing for direct access to the inner ear structures. Once the labyrinth is accessed, it is opened and examined for any abnormalities. Subsequently, a needle or catheter is introduced into the inner ear, through which vestibuloactive drugs are instilled. These medications aim to alleviate the debilitating symptoms associated with Meniere's disease by targeting the vestibular system. The meticulous nature of this procedure requires the use of an operating microscope and specialized surgical instruments to ensure precision and minimize complications.
