20120087 | MP/H Rules/Histology--Kidney: How is the histology coded and what rule(s) apply for "cyst associated renal cell carcinoma," "cystic renal cell carcinoma," and "cystic renal cell carcinoma, clear cell type"? See Discussion.
|
Per SINQ 20031008, these histologies were all coded as 8316/3 [cyst associated renal cell carcinoma]. What are the correct codes for these histologies using the 2007 MP/H Rules?
|
For cases diagnosed 2007 or later, the correct histology code for both cyst associated renal cell carcinoma and cystic renal cell carcinoma is 8316/3. The histology code for cystic renal cell carcinoma, clear cell type is 8255/3.
The steps used to arrive at these decisions are:
Step 1: Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text). Go to the Kidney Histology rules because site specific rules have been developed for this primary.
Step 2: For the first histology, cyst associated renal cell carcinoma, start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H5. According to this rule you are to use Table 1 if you have a renal cell carcinoma and mention of a more specific renal cell type. To locate Table 1, go to Kidney under the Terms & Definitions section. Per Table 1, titled Renal Cell Carcinomas and Specific Renal Cell Types, "cyst associated" is a specific type of renal cell carcinoma. Code the histology to 8316/3 [cyst associated renal cell carcinoma].
Step 3: For the second histology, cystic renal cell carcinoma start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H5. As in the previous example you are to use Table 1 if you have a renal cell carcinoma and mention of a more specific renal cell type. Per Table 1 "cystic" is a specific type of renal cell carcinoma. Code the histology to 8316/3 [cystic renal cell carcinoma].
Step 4: For the third histology, cystic renal cell carcinoma, clear cell type, start at the SINGLE TUMOR module, Rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at Rule H6 which states you are to code histology to 8255 (adenocarcinoma with mixed subtypes) when there are two or more specific renal cell carcinoma types. To determine whether "clear cell" and "cystic" are types of renal cell carcinoma use Table 1 again. According to Table 1, both cystic and clear cell are specific types of renal cell carcinoma. Code the histology as 8255/3 [adenocarcinoma with mixed subtypes].

20120040 | Reportability--Heme & Lymphoid Neoplasms: Is the term myelodysplastic disorder a reportable term? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Myelodysplastic disorder is a synonym for myelodysplastic syndrome (MDS). If no further workup is done or no additional information can be found, code the histology of myelodysplastic disorder to 9989/3 [MDS] for cases diagnosed 1/1/2010 and later.
Refer to the Abstractor Notes section in the Heme DB, Abstractor Notes for MDS. Myelodysplastic (disorder) syndrome is a NOS term. Usually when this diagnosis is made, the physician will conduct further tests to determine a more specific disease in the Myeloproliferative Neoplasms group. Other specific histologies include: refractory anemia with unilineage dysplasia, refractory anemia with ring sideroblasts, refractory cytopenia with multilineage dysplasia, refractory anemia with excess blasts, myelodysplastic syndrome with del(5q), childhood myelodysplastic syndrome. If a more specific disease is diagnosed, code to that specific neoplasm.

20120090 | First course treatment/Chemotherapy: Can a drug be coded as treatment for primary sites or histologies not listed for that drug in the SEER*Rx Database? See Discussion. | The patient was diagnosed with chronic myelogenous leukemia in 2008 followed by a diagnosis of chronic lymphocytic leukemia in 2011. Per the physician statement, the patient started nilotinib in 10/2011 for CML.
The SEER*Rx Database lists CML and GIST as the only primary site/histology combinations treated using nilotinib. Can nilotinib also be coded as treatment for the CLL primary? |
SEER*Rx lists the approved sites/histologies for each drug. However, if you have a physician statement that indicates the drug was given for another site/histology, code the agent as treatment for that site/histology. | 2012 |

20120041 | Primary site/Heme & Lymphoid Neoplasms: How is the primary site coded if the patient presents with diffuse B cell lymphoma involving the nasopharynx and right maxillary sinus with bilateral cervical, right supraclavicular and axillary lymph nodes? See Discussion. | There is one mass in the nasopharynx and right maxillary sinus and the site of origin cannot be determined for this diffuse B-cell lymphoma. The patient also has bilateral cervical, right supraclavicular and axillary lymph nodes.
Should the primary site be coded per Module 7 Rule PH25 because regional nodes are involved or Rule PH22 because both regional and distant nodes are involved? If rule PH22 is used, what is the primary site? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the primary site to C119 [nasopharynx] per Rule PH25.
Per our subject matter expert, use Module 7 Rule PH25 to code the primary site to an organ (nasopharynx and maxillary sinus) because an organ(s) and its regional lymph nodes are involved. The distant lymph nodes are simply part of the staging (the lymphoma has progressed to another lymph node region).
Diffuse large B cell lymphoma originating in the oral cavity and maxillofacial region is rare, but documented. The most common sites for this rare neoplasm are Waldeyer ring, tonsils, nasopharynx, base of tongue, and palatine tonsil. There are also rare cases of diffuse large B cell lymphoma originating in the maxillary sinus. The percentage of cases arising in the nasopharynx is greater than those originating in the maxillary sinus.

20120009 | Histology--Heme & Lymphoid Neoplasms: How is the histology coded when the pathology report states the morphologic features and immunophenotype of a low grade B-cell lymphoma are most compatible with lymphoplasmacytic lymphoma or marginal zone lymphoma? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
Code the histology to 9591/3 [B-cell lymphoma, NOS] per Rule PH28 which states that one is to code the histology when the diagnosis is
There is only one non-specific histology code mentioned, low grade B-cell lymphoma. This term is synonymous with B-cell lymphoma, NOS.
Per the Multiple Primaries Calculator, when comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9671/3 [lymphoplasmacytic lymphoma], it is the same primary. When comparing the histology 9591/3 [B-cell lymphoma, NOS] and 9699/3 [marginal zone lymphoma], it is the same primary.

20110116 | MP/H/Histology--Lung: What is the histology code for "heterologous biphasic sarcomatoid carcinoma of the lung with prominent rhabdomyoblastic and adenoca differentiation"? |
The expert pathologist recommends coding histology to 8980/3 [Carcinosarcoma] for this combination histology. Expert consultation: The designation "carcinosarcoma" is given when the pathology shows differentiation in both the sarcomatous (rhabdomyoblastic) and carcinomatous (adenoca) elements. This is emphasized in the path for this case with the term "biphasic." The term "heterologous" mean that the sarcomatous component is of a type not normal to lung. Rhabdomyoblastic means skeletal muscle differentiation. Because skeletal muscle is not normally found in lung it is heterologous. If it were smooth muscle, it would be homologous because smooth muscle is found in lung (as a part of the bronchi). |

20110060 | Reportability--Heme & Lymphoid Neoplasms: In the absence of any additional information regarding the disease process, is a diagnosis of "polycythemia" reportable if a patient is treated with phlebotomy? | For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph.
No. Polycythemia, NOS is not reportable.
Polycythemia (also known as polycythaemia or erythrocytosis) is a disease state in which the proportion of blood volume that is occupied by red blood cells increases. Blood volume proportions can be measured as hematocrit level. It can be due to an increase in the mass of red blood cells, "absolute polycythemia"; or to a decrease in the volume of plasma, "relative polycythemia".
The phlebotomy is a treatment for the excessive blood volume; therefore, a diagnosis of "polycythemia" without one of the modifying terms listed in the Heme DB under Alternative Names is not reportable.

20110109 | Multiple primaries--Heme & Lymphoid Neoplasms: How many primaries are to be abstracted when a patient is simultaneously diagnosed with multiple myeloma/plasma cell myeloma, plasmacytoma and plasma cell leukemia? |
For cases diagnosed 2010 and forward, access the Hematopoietic Database at http://seer.cancer.gov/seertools/hemelymph. This is accessioned as one primary and the histology is coded to 9732/3 [multiple myeloma]. To arrive at this answer, it is important to first try to determine how many different unique neoplasms there are to correctly identify the number of primaries to report. Per the Heme DB, plasma cell leukemia is an obsolete term. The current term and histology code for this diagnosis is 9732/3 [plasma cell myeloma]. Plasma cell myeloma and multiple myeloma are synonyms per the Heme DB. Therefore, per Rule M2 a single primary exists when there is a single histology. That takes care of the multiple myeloma/plasma cell myeloma and plasma cell leukemia, but not the plasmacytoma. In checking the Heme DB, the terms plasma cell myeloma and multiple myeloma are not synonyms for plasmacytoma. Therefore, we are left to determine whether the multiple myeloma/plasma cell myeloma vs the plasmacytoma represents one or two primaries. Under the Transformation section of the Heme DB, it indicates that plasmacytoma (a chronic disease process) transforms to multiple myeloma (an acute disease process). Per Rule M9, abstract a single primary and code the acute histology when both a chronic and an acute neoplasm are diagnosed simultaneously. The histology is coded to the acute neoplasm when there is no information on the biopsy regarding which is the "later" histology. This update will be added to the Heme Manual.

20110054 | First course treatment/Other therapy--Heme & Lymphoid Neoplasms: Is a transfusion coded as first course treatment for multiple myeloma? See Discussion. | Per the SEER Manual, First Course for Leukemia and Hematopoietic Diseases definitions, Other Hematopoietic states that transfusions are coded as "other" in the Other Treatment fields. Does this mean that a transfusion for chemotherapy-related anemia is coded as treatment for patients with multiple myeloma? | Do not code transfusions as treatment. According to hematopoietic specialty physicians, transfusions are given for such a variety of reasons (anemia, etc.) and should not be coded as other treatment. | 2011 |

20110110 | MP/H Rules/Multiple primaries--Head & Neck: If a 1991 neuroesthesioblastoma [9522/3] of the nasal cavity has subsequent recurrences of the same histology but later "recurs" in 2008 with "sarcoma, NOS, high grade" on a biopsy and a "high grade fibrosarcomatous transformation of esthesioneuroblastoma" [8810/3] on resection, should the subsequent tumor be reported as a new primary if the clinician continues to refer to the tumor as a "recurrence"? See Discussion. |
Are histologic transformations always recurrences of the original tumor? |
Assuming the same primary site for the 2008 lesion, according to the current MP/H rules the high grade fibrosarcoma [8810/3] is a new primary per Head & Neck MPH rule 11 because it is a different histology. The revised MP/H rules will include tables to define tumors that de-differentiate (transform) and recur with what is seemingly a different histology. Although the rules will be changed in the future, we must use the rules in place at this time for this case. |
