Wiki Oncology DX question

[jennifervybiral]

I have a patient that we treated her lung CA with Radation therapy and now we are going to do Prophylactic cranial irradiation to try and prevent brain Mets. We wouldn't code this as a brain Mets becuase she does not have Brain Mets yet. How would you code this??

Thanks

you will code as the lung cancer.
