Central perforation of tympanic membrane, bilateral

This code signifies a hole in the central part of the eardrum affecting both ears. This perforation is typically due to trauma, infection, or chronic inflammation, and it can lead to hearing loss and recurrent ear infections.

Assign this code when documentation explicitly states a central perforation of the tympanic membrane in both the left and right ears. This diagnosis is often made via otoscopy, where a visible defect in the eardrum is observed.

• Ensure documentation specifies "central" perforation; other types (e.g., marginal, attic) have different codes.
• Confirm laterality is explicitly stated as "bilateral" or both "right" and "left" ears are affected.
• Do not use if the perforation is described as total or massive, as those have distinct codes.
