Contusion of unspecified ear, sequela

This code signifies a bruise to an unspecified ear, representing the long-term effects or complications of a previous injury. It indicates that the initial contusion has resolved, but residual issues related to that injury persist.

Apply this code when documenting a patient presenting with a current condition that is a direct consequence of a past contusion to the ear, and the specific ear (left or right) is not documented. This is appropriate for follow-up encounters addressing chronic pain, deformity, or other lasting sequelae from the original injury.

• Requires a seventh character "S" to indicate sequela, meaning the initial injury has healed but residual effects remain.
• Do not use for initial or subsequent encounters for an active contusion; those would use S00.43-A or S00.43-D respectively.
• Ensure documentation clearly links the current condition to a previous ear contusion and specifies the "unspecified" ear if laterality is not noted.
