In simple words: This code represents exposure to natural radiation sources, excluding radon, other naturally occurring radiation, man-made radiation, and sunlight.
Exposure to natural radiation. Excludes1: contact with and (suspected) exposure to radon and other naturally occurring radiation (Z77.123) exposure to man-made radiation (W88-W90) exposure to sunlight (X32)
Example 1: A patient presents with symptoms consistent with radiation sickness after exploring a cave known for high levels of natural background radiation., A geologist working with radioactive minerals develops health issues due to prolonged occupational exposure to natural radiation., A researcher studying high-altitude environments experiences increased exposure to cosmic radiation and develops related symptoms.
Documentation should specify the type of natural radiation exposure, the circumstances of the exposure, the duration of the exposure, and any signs or symptoms related to the exposure.
** Reporting of ICD-10-CM external cause codes is generally not required unless mandated by state regulations or specific payers. However, voluntary reporting is encouraged for injury research and prevention.
