Open bite of right ear, sequela

This code signifies a long-term complication or late effect resulting from an open bite injury to the right ear. It indicates that the initial acute injury has healed, but residual issues, such as scarring, disfigurement, chronic pain, or functional impairment, are still present and being treated.

Apply this code when documentation clearly indicates a patient is presenting for treatment of a residual condition directly attributable to a past open bite of the right ear. The medical record should specify the nature of the sequela (e.g., hypertrophic scar, keloid, nerve damage, chronic infection) and its causal link to the previous injury.

• Ensure the documentation explicitly states the condition is a "sequela" or "late effect" of a previous open bite, not an acute injury.
• Always code the specific nature of the sequela first, followed by this external cause code to indicate the origin.
• Do not use this code for initial treatment of an acute open bite; refer to acute injury codes for that scenario.
