DESCRIPTION

Code indicates the sequence of all reportable neoplasms during the patient's lifetime determined by the central registry. This data item differs from Sequence Number Hospital, because the definitions of reportable neoplasms often vary between hospital and a central registry. When two or more tumors are diagnosed simultaneously, the one with the worst prognosis is assigned the lowest sequence number.

CODES

0	One primary only in the patient’s lifetime.
01-59	Actual number of this primary.
99	Unspecified required sequence number or unknown.
State Registry Defined
60	Only one state registry-defined neoplasm.
61	First of two or more state registry-defined neoplasms.
62	Second of two or more state registry-defined neoplasms.
63-87	Actual number of state registry-defined neoplasms.
88	Unspecified number of state registry-defined neoplasms.

SOURCE

When a new tumor is created, attempt to generate Sequence Number—Central automatically according to NAACCR 2003, Implementation Work Group: Guidelines and Recommendations, as interpreted in UC 02.08.01.01 Consolidate Sequence Number – Central – UC. If system is unable to generate Sequence Number--Central for new the new tumor, system will leave field blank causing an edit error requiring manual resolution.

historical changes

03/26/03	New data item in the 2003 data item set.
03/03/04	Updated Source information to reflect the definition of this field to calculate the tumors for the patient’s lifetime.
08/15/06	Updated range of Allowable Values to 59.
10/10/07	Added IF #760.
2010	Data Item Changes: CCR name (Seq_No_Central) changed to NAACCR name.
07/2015	Revised SOURCE logic to reference UC 02.08.01.01 Consolidate Sequence Number – Central instead of Appendix 27. Appendix 27 was duplicate of UC and has been removed from Volume III. UPDATE logic revised to document that Manual Change is needed at Tumor Level.
