Exposure to X-rays, sequela

This code signifies a health condition or complication arising as a long-term consequence of past exposure to X-ray radiation. It is used when the acute effects of the exposure have resolved, but a chronic or delayed manifestation is now present. This could include conditions like radiation-induced malignancies, cataracts, or other organ damage that develops years after the initial X-ray exposure.

Apply this code when documenting a patient's current diagnosis that is directly attributed to a prior X-ray exposure, such as a radiation-induced cancer or a chronic skin condition. It is appropriate for conditions that have a clear causal link to the radiation, even if the exposure occurred many years ago. Do not use this code for acute radiation sickness or for the immediate effects of a recent X-ray.

• Always link this code to a specific manifestation code (e.g., a malignancy code, a cataract code) to fully describe the patient's condition.
• Ensure documentation clearly establishes the causal relationship between the X-ray exposure and the current sequela.
• The "S" in the seventh character indicates this is a sequela code, meaning it's used for complications or conditions that are the late effects of the initial injury or exposure.
