SEER Inquiry System - Question 20041040 Details

This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Code the CS Tumor Size field to 999 [Unknown; size not stated; not stated in patient record] when the primary site is unknown.

There is a discrepancy in Part I of the CS Manual on page 27, rule 5g, which says that primary site C80.9 should be coded as 888 not applicable. The CS Steering Committee has decided that the last line about unknown and ill-defined sites should be deleted from rule 5g. This issue will be addressed in a CS errata to be distributed in July 2004.
