HCPCS 69633

Tympanoplasty without mastoidectomy (including canalplasty, atticotomy and/or middle ear surgery, initial or revision); with ossicular chain reconstruction and synthetic prosthesis (eg, partial ossicular replacement prosthesis [PORP], total ossicular replacement prosthesis [TORP])

AI EXPLANATION: This outpatient surgical procedure repairs a damaged or perforated eardrum while simultaneously reconstructing the tiny sound-transmitting bones in the middle ear. A surgeon repairs the eardrum membrane and uses an artificial, synthetic implant to replace or reconnect damaged or missing middle ear bones, helping restore the physical structure needed for sound transmission.
