Exposure to oth man-made visible and ultraviolet light, init

This code signifies an initial exposure to artificial light sources, other than welding arcs, that emit visible or ultraviolet radiation. This includes various industrial, commercial, or recreational light sources that can potentially cause adverse health effects. The exposure is the primary reason for the patient's encounter.

Apply this code when a patient presents for the first time due to symptoms or concerns directly related to exposure to man-made visible or ultraviolet light. Examples include eye irritation from prolonged exposure to high-intensity stage lighting, skin erythema from tanning bed use, or other acute effects from non-welding artificial light sources.

• Always use an external cause code (V00-Y99) in conjunction with this code to specify the circumstances of the exposure.
• Do not use for exposures to natural sunlight (use codes from L55.-) or welding arcs (use W89.0XXA).
• Ensure the encounter is documented as the "initial encounter" for the specific exposure event.
