Exposure to laser radiation, initial encounter

This code signifies an injury or adverse health effect resulting from direct exposure to laser radiation. This exposure can lead to various tissue damages, including burns, ocular injuries, or other localized effects depending on the laser type and duration of exposure.

Apply this code when a patient presents for initial treatment of an injury directly caused by laser radiation. This includes accidental exposures in occupational settings, during medical procedures (e.g., cosmetic laser treatments gone awry), or recreational incidents.

• Always assign an external cause code (e.g., W89.XXXA for exposure to other man-made radiation) to provide more detail about the circumstances of the exposure.
• Code any specific injuries (e.g., T20-T25 for burns, H50-H59 for disorders of the eye and adnexa) in addition to this code.
• Ensure the "A" for initial encounter is used only for the first time the patient is seen for this specific exposure.
