Insect bite of left eyelid and periocular area, subs

This code signifies a nonvenomous insect bite affecting the left eyelid or the surrounding periocular region, indicating that the patient is receiving follow-up care for an injury that occurred previously. It describes a superficial skin injury caused by an insect, excluding bites from venomous species like spiders or scorpions.

Apply this code for encounters where a patient is returning for ongoing management, monitoring, or treatment of a nonvenomous insect bite on their left eyelid or periocular area. Documentation should clearly state "subsequent encounter" or similar language indicating follow-up care for the initial injury. This code is appropriate for scenarios such as wound checks, dressing changes, or evaluation of healing progress.

• Ensure documentation explicitly states "subsequent encounter" for the insect bite; otherwise, an initial encounter code (S00.262A) should be used.
• Verify the laterality (left eyelid/periocular area) is clearly documented.
• Distinguish from venomous bites (e.g., T63.4- for venomous insect bite) which are coded differently.
