Inquiry Details

2025 SEER Manual, 105-107. Sequence Number--Central
Question:
Sequence Number--Central/Reportability--Heme & Lymphoid Neoplasms: Is a hematolymphoid disease included in the sequencing if it was not reportable at the time of diagnosis?
Discussion:
Answer:
Do not include the disease in the sequencing if the original hematolymphoid disease was not reportable at time of diagnosis.
The 2025 SEER Manual Sequence Number--Central Coding Instruction 1.a advises: A ‘reportable’ primary refers to the site/histology/behavior of the tumor and the years when reporting was required. Review of the reportability requirements in effect during the diagnosis year will be needed.
