CPT® Code 69667

The procedure described by CPT® Code 69667 involves the surgical repair of a round window fistula, which is an abnormal opening or communication between the middle ear and the inner ear. This condition can lead to various auditory and balance issues, as the integrity of the inner ear is compromised. The round window is one of two key membranes in the inner ear, and its proper function is essential for normal hearing and balance. During the procedure, the physician makes an incision in the posterior wall of the ear canal to access the affected area. A tympanomeatal flap, which is a section of the ear canal skin and underlying tissue, is carefully elevated to expose the round window. The repair is performed using a graft, typically derived from mesodermal or other soft tissue, to close the fistula and restore the normal anatomy of the ear. After the repair is completed, the tympanomeatal flap is repositioned, and the incision is sutured closed, ensuring that the ear is properly sealed and promoting healing.
