Reportability--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.
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.
MP/H Rules/Histology--Thyroid: How is histology coded for a thyroid tumor described as "predominantly papillary carcinoma, tall cell variant, follicular type"?
For cases diagnosed 2007 or later, assign code 8340 [Papillary carcinoma, follicular variant] according to rule H15 for Other Sites.
"Predominantly" and "type" indicate specific histologies. "Variant" does not. See rule H13. The histology in this case is papillary and follicular. Tall cell variant is ignored.
MP/H Rules/Histology--Fallopian Tube: What is the histology code of serous tubal intraepithelial (in situ) carcinoma (STIC), bilateral fallopian tubes?
Assign 8441/2. This is based on the WHO classification for female reproductive system tumors.
EOD/Summary Stage--Eye: How is stage coded for a patient with extranodal non-Hodgkin lymphoma involving bilateral choroids (single focus, both sites) and no lymph node involvement? Since the eyes are a paired site, is this two separate extranodal sites? If so, there are no Summary Stage or EOD tumor codes that best fit this scenario.
Assign as Stage IV as recommended by our expert hematological oncologist. This is a rare occurrence and this type of presentation does not fit the definition of intraocular extension. Stage IV is probably the best stage for this type of presentation, since there are two extranodal organs involved, even though they involve a bilateral site.
Histology--Heme & Lymphoid Neoplasms: How is histology to be coded for acute lymphoblastic leukemia (ALL) and/or precursor B acute lymphoblastic leukemia (Pre-B ALL) for cases diagnosed 2010 and later? The Heme Database has two histology codes for this disease, both 9811/3 and 9836/3, which is the correct histology code?
Code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS].
See the Abstractor Notes section in the Heme DB, when determining how to code histology for a case. It indicates the code 9811/3 is effective for cases diagnosed 2010 and forward. The 9836/3 is listed as obsolete and refers you to code 9811/3. Make sure to check for a specific subtype of B lymphoblastic leukemia/lymphoma [9812/3 - 9818/3] before assigning the NOS code [9811/3].

CS Lymph Nodes/Reg LN Pos/Exam: Is a final pathologic diagnosis of "Level 8 lymph node: Fibroadipose tissue containing a minute lymphoid aggregate, negative for malignancy" a lymph node for the purpose of coding these fields?
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.
Yes. "Fibroadipose tissue containing minute lymphoid aggregate" qualifies as a lymph node. Include in count as one lymph node examined in the example above assuming this is regional to the primary site.
Primary Site--Head & Neck (Middle ear): How do you code site for a skull based tumor consistent with a low grade papillary adenocarcinoma of "endolymphatic sac origin"?
Code Primary Site to C30.1 [Middle ear]. The endolymphatic sac is part of the inner ear labyrinth located with in the petrous portion of the temporal bone.
Reportability/Histology--Tongue: Is high grade squamous dysplasia of the tongue reportable; and is it the same as carcinoma in situ (CIS), code 8077/2?
High grade squamous dysplasia of the tongue is reportable as of 2021 and later as 8077/2.
First Course Treatment/Immunotherapy--Colon: Can "Sandostatin" be coded for treatment of carcinoid tumors of the colon because it flushes tumor cells from the colon in addition to controlling diarrhea?
Do not code Sandostatin (Ocreotide Acetate) as treatment. This is an ancillary drug used to treat symptoms of diarrhea. SEER Book 8 is undergoing revision and will include this change.
Multiple Primaries (Pre-2007): Would osteosarcoma of the right arm diagnosed four years after malignant fibrous histiocytoma, also in the right arm, be a second primary when the physician states, "the patient's disease progressed to sarcoma after radiation was administered?"
For tumors diagnosed prior to 2007:
The osteosarcoma is a second primary. The first three digits of the histology codes are different: 8830 [Malignant fibrous histiocytoma] and 918_ or 919_ [Osteosarcoma]. In addition, the diagnoses are four years apart. According to SEER rules, these are separate primaries.
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.
