Personal history of irradiation, presenting hazards to health

This code indicates a patient's past exposure to radiation, which is now considered a potential risk factor for future health issues. This history is significant even if the patient is not currently experiencing symptoms directly related to the irradiation.

Assign this code when a patient's medical record documents a history of therapeutic or accidental radiation exposure that necessitates ongoing monitoring or influences current treatment decisions. This is particularly relevant for patients with a history of cancer treatment involving radiation, or those with occupational or environmental radiation exposure.

• This is a history code and should be used as a secondary diagnosis to indicate a risk factor, not a current condition.
• Do not use this code for current radiation sickness or acute effects of radiation; those have specific codes.
• Ensure the documentation clearly states a history of irradiation and that it poses a hazard to health.
