Traumatic rupture of unspecified ear drum, initial encounter

This code signifies a tear or perforation of the eardrum (tympanic membrane) resulting from an external force or injury, where the specific ear (left or right) is not documented. This traumatic event disrupts the normal function of the eardrum, potentially leading to hearing loss or increased susceptibility to middle ear infections.

Use this code when documentation clearly indicates a traumatic rupture of the tympanic membrane, but the laterality (left or right ear) is not specified. This code is appropriate for the initial treatment or active phase of care for the injury. Supporting documentation would include physician notes detailing the mechanism of injury and the diagnosis of a ruptured eardrum without laterality.

• Ensure the documentation explicitly states "unspecified" or lacks laterality for the ear drum rupture.
• Do not use this code if the laterality (left or right) is known; instead, select the more specific S09.21XA (right) or S09.22XA (left).
• Remember the "A" seventh character indicates an initial encounter for active treatment of the injury.
