Cntct w & expsr to radon and other naturally occur radiation

This code indicates a patient's documented contact with or suspected exposure to radon gas or other forms of naturally occurring radiation. It is used when the exposure itself is the focus of the encounter, rather than a resulting medical condition. This could involve environmental exposure in a home or workplace.

Apply this code when a patient presents for evaluation due to concerns about radon exposure, such as after a positive home radon test, or when a healthcare provider suspects exposure based on environmental factors. It is appropriate for screening, monitoring, or counseling related to such exposures before any definitive health effects are diagnosed.

• Do not use this code if a specific condition caused by radiation exposure has already been diagnosed; instead, code the specific condition and the appropriate external cause code (W88-W90, X39.0-).
• This code is for naturally occurring radiation; differentiate from man-made radiation exposures.
• Consider additional codes for symptoms or signs if present, but this code captures the exposure itself.
