Open bite of unspecified part of head, sequela

This code describes the long-term effects or complications arising from an open bite injury to an unspecified part of the head. It indicates that the initial injury has healed, but residual issues, such as scarring, nerve damage, or functional impairment, persist.

Use this code when documenting a patient presenting with a current condition that is a direct consequence of a previously sustained open bite to the head. The medical record should clearly link the current sequela to the past open bite injury, even if the original injury site is not specified.

• Requires a seventh character "S" to indicate sequela, meaning the patient is seen for complications or residual effects of the original injury.
• Do not use for initial encounters or subsequent encounters for active treatment of the original open bite.
• Always code the specific nature of the sequela first, followed by this code to indicate the cause.
