CPT® Code 69801

The procedure described by CPT® Code 69801 is known as labyrinthotomy with perfusion of vestibuloactive drug(s) via a transcanal approach. This surgical intervention is primarily indicated for the treatment of Meniere's disease, a condition characterized by episodes of vertigo, tinnitus, and hearing loss due to abnormal fluid accumulation in the inner ear. The inner ear, or labyrinth, is a complex structure composed of both bony and membranous components, which play crucial roles in balance and hearing. The bony labyrinth provides a protective outer layer, while the membranous labyrinth contains the sensory organs responsible for these functions. Accessing the inner ear is achieved through a transcanal approach, which involves making an incision in the posterior aspect of the ear canal to elevate a tympanomeatal flap. This allows the surgeon to reach the middle ear and subsequently the labyrinth. The procedure involves meticulous dissection using an operating microscope and specialized surgical instruments to navigate through the delicate structures of the ear. Once the labyrinth is accessed, a needle or catheter is introduced into the inner ear, allowing for the direct instillation of vestibuloactive drugs aimed at alleviating the debilitating symptoms associated with Meniere's disease.
