Personal history of irradiation

📋Clinical Description

This code indicates a patient's past exposure to therapeutic radiation, such as for cancer treatment, which is no longer ongoing. It signifies a historical event that may have long-term health implications, even if the primary condition for which radiation was given is resolved. This history is crucial for assessing future health risks and potential late effects.

🎯When to Use

Apply this code when documenting a patient's medical history that includes prior therapeutic radiation, regardless of the original reason for treatment. This is relevant for follow-up care, risk assessment for secondary malignancies, or when evaluating symptoms that could be related to past radiation exposure. It should be used even if the patient is not currently undergoing radiation therapy.

💡Coding Tips

This is a history code, indicating a past event, not current treatment.
Do not use for environmental or occupational radiation exposure; refer to the Excludes1 notes for appropriate codes.
Always code the primary condition or reason for the current encounter in addition to this history code.
