Exposure to X-rays, initial encounter

This code signifies an individual's initial exposure to X-rays, typically in a non-diagnostic or accidental context, leading to potential health effects. It is used when the patient presents for the first time due to this specific exposure event. This code does not apply to routine diagnostic X-ray procedures.

This code is appropriate for documenting the initial encounter for a patient who has been exposed to X-rays due to an occupational accident, equipment malfunction, or other non-medical imaging circumstances. It would be used when the patient first seeks medical attention for symptoms or concerns related to this exposure.

• Ensure this code is only used for the initial encounter related to the X-ray exposure. Subsequent encounters would use the appropriate seventh character.
• Always code the specific effects or symptoms of the radiation exposure in addition to this external cause code.
• Do not use this code for diagnostic X-ray procedures performed as part of patient care.
