2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
EOD-Extension/EOD-Lymph Nodes: Can the AJCC TNM/Stage be used to help code these fields when there is limited text information in the medical record that describes the tumor involvement?
For cases diagnosed 1998-2003:
Yes, this staging information can be used to help code the SEER EOD fields but only if a physician does the TNM/Stage at the time of diagnosis and there is limited text information that describes tumor involvement.
Multiplicity Counter: Is there a time frame for the Multiplicity Counter or is it related to the duration for counting new tumors (i.e. 5 years for breast, etc) to capture the number of "local recurrences"?
Record the number of tumors counted as a single primary at the time the case is abstracted. Later, if additional tumors are determined to be the same primary, update this field once. Do not update the multiplicity counter more than once.
EOD-Extension--Head & Neck: How do you code extension for a supraglottic larynx primary with "pre-epigolottic space" invasion?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 65 [Pre-epiglottic tissues]. Extension to "pre-epiglottic space" is equivalent to extension to "pre-epiglottic tissue."
Date of Conclusive Terminology: Is there an applicable timeframe when coding this field?
There is no strict timeframe for Date of Conclusive Terminology. The diagnosis using conclusive terminology could be made any time following the diagnostic work-up.
The date of conclusive terminology is related to code 2 [ambiguous term followed by conclusive term] in the data item "Ambiguous terminology." Assign code 2 when a conclusive diagnosis is made 60 days or more after a diagnosis using ambiguous terminology. Record the date of the conclusive diagnosis in "Date of Conclusive Terminology."
Histology (Pre-2007)--Lung: What code is used to represent the histology "mucin-producing bronchoalveolar carcinoma?" Is mucin-producing synonymous with mucinous?
For tumors diagnosed prior to 2007:
Code histology as 8253 [Bronchiolo-alveolar carcinoma, mucinous]. Mucin-producing bronchoalveolar carcinoma is best classified in ICD-O-3 as Bronchiolo-alveolar carcinoma, mucinous.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
EOD-Extension--Stomach: How is this field coded for a stomach primary that has metastases to "Sister Mary Joseph's Nodes?"
For cases diagnosed 1998-2003: For a stomach primary, code extension to 70 [Abdominal wall]. Sister Mary Joseph's nodule is a cutaneous umbilical metastasis most commonly from an intra-abdominal primary.
This rare form of cutaneous umbilical metastasis results from spread of tumor within the falciform ligament. The umbilicus is part of the abdominal wall.
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?
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.
