Open bite of unspecified eyelid and periocular area, sequela

This code signifies a long-term complication or late effect resulting from an open bite injury to an unspecified eyelid and/or the surrounding periocular tissues. It indicates that the initial injury has healed, but residual issues, such as scarring, functional impairment, or cosmetic deformity, are present. The "unspecified" nature means the specific eyelid (upper or lower) or precise periocular area is not documented.

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 eyelid or periocular region. This applies when the acute phase of the injury has passed, and the current treatment addresses the sequela. Documentation should clearly link the current problem to the prior open bite and indicate the chronic nature of the condition.

• Always sequence this sequela code after the code for the specific nature of the sequela (e.g., scar, ectropion).
• Ensure documentation specifies "sequela" or "late effect" to justify using the 7th character 'S'.
• Avoid using this code for acute open bite injuries; those require codes from the initial encounter or subsequent encounter categories.
