Record the appropriate code(s) for up to five sites of distant metastases present at the time of initial diagnosis. Include a distant site here if it is considered metastatic by the AJCC Manual for Staging of Cancer. See Appendix E for General Sites Codes.

The following systemic diseases should not have sites of metastases recorded: leukemia, Letterer-Siwe disease, multiple myeloma, reticuloendotheliosis, Hodgkin's and Non-Hodgkin's lymphomas, and unknown primaries.

When you are abstracting an unknown primary, you may not code site(s) of metastases here, because you cannot be sure they are distant sites.

Precede any single digit codes with a zero.
