T28.419A
ICD-10-CMThis code signifies a thermal injury to the tympanic membrane, where the specific ear (left or right) is not documented. It indicates damage to the eardrum caused by heat, chemicals, or radiation, without further specification of the affected side.
Apply this code when a patient presents with a burn to the eardrum, and the medical record does not specify whether it's the right or left ear. This is appropriate for the initial treatment of such an injury, before definitive care or follow-up.
