Multiplicity Counter: Are in situ tumors diagnosed more than 60 days after invasive tumors of the same site and histology included in the Multiplicity Counter?
Multiplicity Counter: Is there a time frame for the Multiplicity Counter or is it related to the duration for counting new tumors (i.e. 5 years for breast, etc) to capture the number of "local recurrences"?
Neoadjuvant Treatment/Date Therapy Initiated--Breast: If Tamoxifen has been used since 2000 for the treatment of hyperplasia, should it be coded as neoadjuvant treatment for a 2004 diagnosis of breast cancer?
Other Cancer-Directed Therapy--Hematopoietic, NOS: Is there a hierarchy for selecting which code to use when a patient receives more than one type of "other treatment"? See Description.
Other Therapy: Can herbal therapy be coded when used as a single therapy or when used in combination with conventional therapy as a complimentary treatment? See Discussion.
