Notes

**Note 1**: This item reflects the validity of the classification of the item CS Mets at DX only according to the diagnostic methods employed. **Note 2**: If a specific subcategory of M1 will be derived from CS Mets at DX, then determine if there was any pathological evidence for the highest subcategory. If so, select an Eval code that will derive a "p" staging basis. If there was only clinical evidence of the highest subcategory, select an Eval code that will derive a "c" staging basis. See also CS Mets Eval in Part 1.
