Exposure to welding light (arc), subsequent encounter

This code signifies a follow-up encounter for an injury resulting from exposure to intense light produced by welding, commonly known as "welder's flash" or arc eye. The injury typically involves the cornea and conjunctiva, leading to symptoms like pain, photophobia, and blurred vision. This code is used when the patient is seen for continued care after the initial treatment.

Apply this code when a patient presents for a subsequent visit related to an injury caused by welding light exposure, such as for re-evaluation of symptoms, medication refills, or monitoring of healing. This includes appointments following an emergency room visit or an initial clinic consultation for the same condition.

• Ensure documentation clearly indicates this is not the initial encounter for the injury.
• Always sequence this code after the primary injury code, such as a corneal abrasion or conjunctivitis.
• Verify the encounter type is indeed "subsequent" and not an initial or sequela encounter.
