Female patient was diagnosed with a RUO quadrant breast cancer (C50.411) who received chemo-radiation.
A year later she was diagnosed with breast cancer on the left central breast. Will the left central breast cancer be coded also as primary c50.112 or C79.81?
If the documentation stated recurrent left central breast cancer with history of right breast cancer, will C79.81 be the code for the left central breast cancer?
We don’t have pathology report available as this is for radiology department visit. I am quite confused as to when the C79.81 be used.
Per ICD guideline when patient had a lumpectomy due to breast cancer and the cancer appeared on another quadrant this new cancer will still be coded as primary cancer.
Any clarification will be greatly appreciated.
