Open bite of left eyelid and periocular area, sequela

This code signifies a healed injury, specifically an open bite wound affecting the left eyelid and the surrounding periocular tissues, where the residual effects or complications of that original injury are now being treated. These sequelae could include scarring, nerve damage, chronic pain, or functional impairment resulting from the initial bite.

Apply this code when a patient presents for treatment of long-term complications or residual conditions directly attributable to a past open bite injury of the left eyelid and periocular area. Documentation should clearly indicate that the current condition is a sequela of a previously sustained bite wound, rather than an acute injury.

• Always sequence this sequela code first, followed by a code describing the specific nature of the sequela (e.g., scar, nerve damage).
• Ensure the medical record explicitly states the current condition is a "sequela" or "late effect" of a past bite injury.
• Distinguish carefully from acute open bite injuries, which would use codes from the acute injury section without the "S" seventh character.
