Tympanoplasty (August 2008)
August 2008 pages 4-6 Coding Brief:Tympanoplasty Sound transmission for proper hearing begins with the tympanic membrane (commonly known as the eardrum). Surgical treatment(s) may be required for patients with conductive hearing loss. Conductive hearing loss may be the result of ossicular erosion or fixation from chronic ear disease; blunt or penetrating trauma; congenital, neoplastic, or inflammatory causes; cerumen impactions; stenosis or atresia of the external auditory canal; middle ear effusion; tympanosclerosis; or a perforation of the tympanic membrane. Hearing loss may be due to abnormality of the tympanic membrane or the ossicles (malleus, incus, and stapes) or due to...

Article Overview
This premium article explains tympanoplasty coding in CPT and outlines the major procedure families, related surgical anatomy, and terminology used in coding ear repair and reconstruction procedures. It is aimed at coding professionals, auditors, and clinicians who need to distinguish among tympanoplasty variations, related ear procedures, and supporting definitions in an otolaryngology context.
Why This Topic Matters
Correctly identifying the tympanoplasty family and related ear surgery terminology is important for accurate CPT reporting, especially when procedures involve the tympanic membrane, middle ear, ossicles, mastoid work, grafting, or revision surgery.
