Exposure to excessive heat of man-made origin, subs encntr

This code signifies a patient's follow-up encounter for health issues resulting from overexposure to man-made heat sources. This includes conditions like heatstroke, heat exhaustion, or burns, where the initial injury or illness was caused by artificial heat, such as industrial equipment, fires, or heated objects.

Apply this code when a patient presents for ongoing treatment, evaluation, or management of a condition previously diagnosed as being caused by excessive heat of man-made origin. This would include subsequent visits for wound care after a burn from a hot stove or follow-up for persistent symptoms after heat exhaustion from working near a furnace.

• Always sequence this code after the primary diagnosis describing the specific heat-related condition (e.g., T67.0XXA for heatstroke).
• Ensure the documentation clearly indicates the heat source was man-made and that this is a subsequent encounter.
• Distinguish from natural heat exposure (e.g., sun) and initial encounters for the same injury.
