For tumors diagnosed prior to 2007:

No. SEER determines its reportable list from the ICD-O-3. The above terms are listed as tumor-like lesions and conditions, but are not in situ or malignant.

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 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.

This is a single primary per Rule M2 which indicates to abstract a single primary when there is a single histology. Code the histology to 9590/3 [lymphoma] and the primary site to C629 [testes. Unless your software has edits that prevent coding laterality for lymphomas, code the laterality as bilateral. Up to half of extranodal lymphomas occur in multiple sites, particularly in paired sites.

SEER*Educate provides training on how to use the Heme Manual and DB. If you are unsure how to arrive at the answer in this SINQ question, refer to SEER*Educate to practice coding hematopoietic and lymphoid neoplasms. Review the step-by-step instructions provided for each case scenario to learn how to use the application and manual to arrive at the answer provided. https://educate.fhcrc.org/LandingPage.aspx.

For cases diagnosed prior to 1/1/2010:Do not change the histology to small lymphocytic lymphoma (9670/3). The chronic lymphocytic leukemia has advanced/progressed and disseminated into other tissues from the blood during the last six months. If the patient presents with disease in the blood and/or bone marrow only, code to CLL. If a lymph node or other solid tissue is involved initially, code to SLL. For the case cited, the tissue involvement occurred six months after the initial diagnosis and the histology code is not changed to reflect the progression of disease.

For cases diagnosed 2010 forward, 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 cases diagnosed 1998-2003:

Yes. Use the scheme on page 180 for MALT lymphoma. The ICD-O-2 morphology code 9715 was omitted in error. It should have been added when the EOD was printed in 1998.

For cases diagnosed 1998-2003:

Evaluate each case carefully.

1. Code the EOD-Extension field to 12 [Myometrium-inner half] because the pathology report indicates involvement of the myometrium "to the level of." However, if you feel that you cannot make that determination with certainty and you cannot ask a pathologist for clarification, then code the EOD-Extension field to 14 [Myometrium, NOS].

2. Code the EOD-Extension field to 12 [Myometrium-inner half] for cases with "superficial" myometrial invasion.

For cases diagnosed 1998-2003:

Ignore these terms when coding extension to 10 or 30. These terms do not verify involvement by pancreatic cancer of the organs mentioned. Other non-malignant circumstances could cause these conditions.

For tumors diagnosed prior to 2007:

Code the Histology field to 8522/3 [infiltrating duct and lobular carcinoma] per rule 1 of the Coding Complex Morphologic Diagnoses, because the tumor is both lobular and ductal.

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 prior to 1/1/2010:The patient does not have two different malignancies. Code the Histology field to 9700/3 [mycosis fungoides], the specific type of cutaneous T cell lymphoma. Mycosis fungoides is one of several types of cutaneous T cell lymphoma. Physicians often refer to mycosis fungoides by the "umbrella term" cutaneous T cell lymphoma.

The table indicates that the broad category of "T/NK-cell NHL" (which includes CTCL) and mycosis fungoides are presumably separate primaries because several entities are included in that broad category. In the specific case cited above, one entity (CTCL) within the broad category (T/NK-cell NHL) and mycosis fungoides are not separate primaries.

For cases diagnosed 2010 forward, 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.

Code the Radiation field to 2 [Radioactive implants]. Codes for radiation are based on HOW the radiation is delivered, rather than the particular type of radioactive material used.

Radioactive eye-plaques contain rice-sized iodine-125 or palladium-103 seeds which emit low energy photons. They are sewn or glued into the eye. The plaque remains for 5 to 7 days and is then removed.

For cases diagnosed prior to 1/1/2010:

Code the Histology field to 9989/3 [myelodysplastic syndrome] and the Date of Diagnosis field to June 2001.

For cases diagnosed 2010 forward, 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.
