Exposure to infrared radiation, subsequent encounter

This code signifies a patient's follow-up care for injuries or conditions resulting from exposure to infrared radiation. It indicates that the initial treatment for the infrared radiation exposure has already occurred, and the current encounter is for ongoing management, healing, or complications.

Use this code for subsequent visits related to burns, ocular damage, or other adverse effects caused by infrared radiation. This includes encounters for wound care, monitoring of eye conditions, or rehabilitation following the initial injury.

• Always pair this external cause code with a primary diagnosis code describing the specific injury or condition.
• Ensure documentation clearly indicates that this is not the initial encounter for the infrared radiation exposure.
• Distinguish from initial encounters (W90.1XXA) and sequela (W90.1XXS) based on the patient's current stage of care.
