Someone asked me when would be a proper time for a Pathologist to use a V10.3 diagnosis code. We have a patient who had breast cancer. She came in much later and had a sentinal node removed. The sentinal node was negative for neoplasm, but we want to use the V10.3. There is a question as to how long after you've had breast cancer, can you start to use the V10.3 code. The question was is it 2 or 5 years? I can't find anything that says there is a time limit requirement to use the code. Anyone have any definitive information?????
