For cases diagnosed prior to 1/1/2010:Because there is no cell indicator information, code 9 [cell type not determined] in the grade/cell indicator field. Do not code grade for lymphoma. For lymphoma and leukemia this field is the cell indicator.

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 cases diagnosed prior to 1/1/2010:The 2008 diagnosis is not a new primary according to the Definitions of Single and Subsequent Primaries for Hematologic Malignancies (the tri-fold heme table) using the pathology report diagnosis from the facility where the procedure was performed (Hospital A). Since Hospital A disagreed with the slide review and did not amend their diagnosis based on the slide review, do not use the slide review diagnosis in this case.

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 cases diagnosed prior to 1/1/2010:Accession this case as plasmacytoma diagnosed in Feb. 2003. Each of the subsequent diagnoses are not abstracted as new primaries. They are the "same," one primary only, according to the Definition of Single and Subsequent Primaries for Hematologic Malignancies (the tri-fold heme table).

The 2003 diagnosis is a classic example of extraosseous plasmacytoma (9734/3).

Plasmacytoma and multiple myeloma would be two primaries in the new hematopoietic rules taking effect in 2010.

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 cases diagnosed 2007 or later:

Use the 2007 MP/H rules for urinary sites to assess tumors diagnosed in 2007 or later.

For the example above, use the 2007 rules to determine whether or not the bladder tumor diagnosed in 2007 is a new primary. Use the Multiple Tumors module when comparing a 2007 or later diagnosis to an earlier diagnosis. Start with rule M3. Stop at rule M8. The 2007 bladder urothelial tumor is not a new primary since there is an existing 2006 renal pelvis urothelial primary.

For cases diagnosed 2007 or later:

MP/H Rule H17 for Other Sites applies. Code the histology 8140 [adenocarcinoma].

The ICD-O-3 code for large cell neuroendocrine carcinoma is 8013 and the code for adenocarcinoma is 8140.

The histology code for basal cell carcinoma with skin appendage differentiation is 8098/3. Basal cell carcinomas (8090-8110) are not reportable to SEER. Skin appendage tumors are not reportable to SEER unless stated to be carcinoma or stated to be malignant.

According to our pathologist consultant, basal cell carcinoma with focal skin appendage differentiation is basal cell carcinoma which exhibits adnexal (appendage) features, but it is still basal cell carcinoma.

The case example above is not reportable to SEER.

For cases diagnosed 2007 or later:

Assign code 8310 [Clear cell adenocarcinoma] according to rule H13. Ignore "cyst" when determining the histologic type for ovarian malignancies. For this case, the only histology is clear cell.

The histologies for the common ovarian epithelial malignancies are serous, mucinous, endometrioid, clear cell, and transitional cell/Brenner. This clarification will be added to the rules in the next revision.

For cases diagnosed 2007 or later:

When the final diagnosis indicates that the microscopic section contains the detailed diagnosis, use the microscopic description to code the histology.

Otherwise, code from the final diagnosis only and not from the microscopic description. The final diagnosis is usually the pathologist's conclusion after consideration of the various choices listed in the microscopic description. The histology code should represent the pathologist's final conclusion.
