If the patient is being managed and treated as a case of primary lung cancer, report the lung diagnosis as a separate primary.

For cases diagnosed 2007 or later:

Using the pre-2007 multiple primary rules, the PTCC of the bladder in 2000 and the invasive TCC of the right ureter in Nov. 2004 would have been abstracted as separate primaries.

Use the 2007 MP/H rules to evaluate the May 2007 diagnosis. Start with rule M3. Stop at rule M8. The May 2007 diagnosis is the same primary.

Rule M4 does not apply because of the 2000 bladder primary. A clarification will be added to M4 to stress that for the urinary rules, any urinary tumor up to the present point in time is counted when applying this rule.

For cases diagnosed prior to 1/1/2010:Primary site:

Code the primary site to C421 [bone marrow] per primary site coding instructions for leukemia in the 2007 SEER manual, page 70.

Surgery of other site:

Since all surgical procedures for hematopoietic diseases are coded in the data item Surgery of Other Site, assign code 1 [Nonprimary surgical procedure performed].

For cases diagnosed 1/1/10 and later, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.

For tumors diagnosed prior to 2007:

Code histology to 8020 [carcinoma, undifferentiated]. "Sinonasal" refers to anatomic location of primary site not histology.

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.

For tumors diagnosed prior to 2007:

The presence of numerous/multiple polyps is not necessarily adenomatous polyposis coli. Adenomatous polyposis is an extreme condition usually characterized by the presence of hundreds of polyps and should be identified as such either clinically or pathologically.

Look for the term "Familial adenomatous polyposis," FAP or one of its synonyms:

Adenomatosis of the colon and rectum [ACR]

Familial adenomatous colon polyposis

Familial colonic polyposis

Multiple familial polyposis

In the absence of these terms, the following probably indicate a diagnosis of FAP:

Hundreds of adenomatous polyps throughout large intestines, and at times, throughout the digestive system

Development of polyps as early as ten years of age, but more commonly at puberty

History of colectomy

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.

For cases diagnosed 1998-2003:

Code EOD-Lymph Nodes fields as follows for the examples given:

1) 9 [Unknown; not stated] for a "hilar mass"

2) 2 [Mediastinal] for a "mediastinal mass"

3) 2 [Mediastinal] for "enlarged" or "greater than 1 cm," if used to describe any of the named lymph nodes listed under code 2 in the EOD-Lymph Nodes field.

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.For tumors diagnosed 2004 only:

Code the CS Site Specific Factor 4 to 999 [Unknown or no information; Not documented in patient record]. If there is no report of a lab test in the health record, code as 999.

Code this field to 000 [Test not done] when there is a statement in the record that a test was not performed.

Tumors diagnosed 1/1/2005 forward no longer have PAP coded in the Site Specific Factor 4 field.
