ICD-O-3 Hematopoietic Primaries Table (PDF) - 3/15/2001
The hematopoietic primaries table indicates whether two hematopoietic diseases (such as a lymphoma and a leukemia) diagnosed separately and coded in ICD-O-3 should be considered the same primary (S) or different primaries (D). The table is based on current medical understanding of these diseases as they are listed in ICD-O-3. This table replaces pages 15-37 in the SEER Program Code Manual (3rd edition, 1998) (PDF) for cases diagnosed on or after January 1, 2001. This table replaces Appendix B of the Commission on Cancer's ROADS manual for cases diagnosed on or after January 1, 2001.
