HCPCS 69632

Tympanoplasty without mastoidectomy (including canalplasty, atticotomy and/or middle ear surgery, initial or revision); with ossicular chain reconstruction (eg, postfenestration)

AI EXPLANATION: This outpatient surgical procedure repairs a hole or tear in the eardrum while simultaneously reconstructing the chain of tiny bones in the middle ear. During the operation, a surgeon uses a graft of tissue to patch the eardrum and realigns, repairs, or replaces the hearing bones—known as the ossicles—to restore the natural pathway for sound vibrations. The surgeon may also widen or reshape portions of the ear canal and middle ear space to clear disease and improve healing.
