Total perforations of tympanic membrane, bilateral

This code signifies the complete absence or destruction of the eardrum in both ears. It indicates a significant and widespread defect affecting the entire tympanic membrane bilaterally, often leading to severe hearing impairment.

Use this code when documentation clearly states "total perforation" or "complete perforation" of the tympanic membrane in both the right and left ears. This diagnosis is typically made upon otoscopic examination revealing the extensive defect.

• Differentiate from partial perforations, which are coded differently based on laterality and specific location.
• Ensure documentation specifies "total" or "complete" for both ears; otherwise, a less specific code may be more appropriate.
• Consider any associated hearing loss (e.g., conductive hearing loss) and code it as a secondary diagnosis.
