Note 1 This SSDI is effective for diagnosis years 2021+
Note 2 Physician statement of Ki-67 (MIB-1), also referred to as the “Proliferative Index” can be used to code this data item.
Note 3 Ki-67 is a marker of cell proliferation. A high value indicates a tumor that is proliferating more rapidly.
Note 4 Ki-67 results are reported as the percentage cell nuclei that stain positive. As of early 2017, there are no established standards for interpretation of results or for cutoffs for positive and negative.
Note 5 If neoadjuvant therapy is given, record the assay from tumor specimens prior to neoadjuvant therapy.
Note 6 A specific value (0.0-100.0) takes priority over XXX.4, XXX.5 or XXX.6. Only use these values when that is the only information available.
