Contusion of left eyelid and periocular area, init encntr

This code signifies a bruise or blunt trauma to the left eyelid and the surrounding tissues of the eye socket. It indicates damage to the soft tissues without a laceration or open wound, occurring during the initial phase of treatment for the injury.

Apply this code for patients presenting with ecchymosis, swelling, or tenderness of the left eyelid and periorbital region due to impact, such as from a fall, sports injury, or assault. Documentation should clearly state "contusion," "bruise," or "black eye" affecting the left side, and confirm it's the first time the patient is being seen for this specific injury.

• Ensure laterality is correctly identified as "left"; use S00.11XA for the right side.
• Distinguish from open wounds (lacerations) of the eyelid, which use codes from the S01.1- series.
• The "A" suffix indicates an initial encounter; use "D" for subsequent encounters and "S" for sequela.
