Venous angiomas (9122/0) are not reportable wherever they arise. The primary site for venous angioma arising in the cerebellum is C490.  The combination of 9122/0 and C490 is not reportable. Venous angioma is a venous abnormality, currently referred to as a developmental venous anomaly (DVA).

This case should be accessioned as two primaries per Rule M13. Code the histology for the 7/31/08 diagnosis to 9680/3 [diffuse large B-cell lymphoma] and the code the histology for the 10/14/2010 diagnosis to 9698/3 [follicular lymphoma, grade 3A of 3]. Rule M13 applies to this case because the neoplasm was originally diagnosed in the blast or acute phase (DLBCL) and reverted to a less aggressive or chronic phase (follicular lymphoma) after treatment.

Per the "Transformations to" section in the Heme DB for follicular lymphoma, grade 3 transforms to diffuse large B-cell lymphoma [9680/3]. This means that the follicular lymphoma is the chronic neoplasm and that DLBCL is the acute neoplasm. In this case, the chronic neoplasm was diagnosed after the acute neoplasm was diagnosed and treated (with chemotherapy).

Do not Stop at Rule M4 because diffuse large B-cell lymphoma and follicular lymphoma (both NHL's) were not present in the same node(s) AT THE SAME TIME.

Per PH Rule22, code the primary site to C779 [lymph nodes, NOS].

Rule PH22 is a default rule for lymphomas that is used when there is no other information regarding the primary site and the Heme DB does not indicate a primary site under its Primary Site(s) section. Rule PH27, code the primary site to unknown [C809], does not apply. Only use C809 [unknown] as the primary site when there is no evidence of lymphoma in lymph nodes AND the physician documents that the lymphoma originates in an organ(s).

Code the histology to 9732/3 [multiple myeloma].

Ambiguous terminology is used to accession cases (determine reportability) because it has been used for over 30 years to do so. Any deviation from using ambiguous terminology to determine case reportability would cause the reporting of incidence counts to vary. In this case, there was a reportable, ambiguous terminology diagnosis of multiple myeloma on the pathology report.

The instruction "Do not code histology based on ambiguous terminology" is intended to be used when there is a reportable and reportable stated in the diagnosis. Ambiguous terminology cannot be used to report the more specific diagnosis in cases of Heme & Lymphoid neoplasms. For example, if the pathology report final diagnosis was "Myeloproliferative neoplasm, probably Polycythemia Vera" the histology would be coded as myeloproliferative neoplasm, unclassifiable [9975/3]. The ambiguous terminology indicates that the genetic testing, immunophenotyping, etc., probably are not complete or are not diagnostic of the more specific disease. Wait to code the histology until there is a definite diagnosis given.

Per Appendix F, a secondary myelofibrosis is not a reportable case.

Secondary myelofibrosis is not listed as a synonym for primary myelofibrosis in the Heme DB. The term "secondary myelofibrosis" means that the myelofibrosis was caused by, in this case, the essential thrombocythemia.

The diagnosis "consistent with myeloproliferative disorder" is also not a new reportable diagnosis. "Myeloproliferative disorder" refers to a group of diseases (an NOS category) that includes essential thrombocythemia, which was originally diagnosed in 1998, prior to reportability for this disease type.

Urine cytology positive for malignancy is reportable. Code the primary site to C689 in the absence of any other information.

However, if a subsequent biopsy of a urinary site is negative, do not report the case.

For 2013 diagnoses and forward, report these cases when they are encountered. Do not implement new/additional casefinding methods to capture these cases.

As always, do not report cytology cases with ambiguous terminology.

Code the histology to 9591/3 [B-cell lymphoma, NOS].

After searching the Heme DB for the term , no B-cell leukemia/lymphoma NOS code is found. However, the diagnosis of B-cell lymphoblastic leukemia/lymphoma is found. This case scenario does not specify that this is a lymphoblastic leukemia/lymphoma; therefore, the histology code 9811/3 [B-cell lymphoblastic leukemia/lymphoma, NOS] cannot be applied.

A subsequent search of the Heme DB for the term returns "Non-Hodgkin lymphoma, NOS" [9591/3]. Under the Alternative Names section of the Heme DB, B-cell lymphoma, NOS, is a synonym for Non-Hodgkin lymphoma, NOS. Therefore, the B-cell lymphoma NOS code [9591/3] is the most appropriate histology code to use for this case.

This will be added to the next revision of the Heme DB and Manual.

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].

Code the histology to 9680/3 [diffuse large B-cell lymphoma (DLBCL)].

For CLL (and CLL/SLL), Richter's transformation represents when CLL changes into DLBCL. In this case, there was a biopsy that demonstrated a diagnosis of the chronic disease (CLL/SLL) transforming (Richter's transformation) into an acute disease DLBCL.

Per Rule M8, one is instructed to abstract the acute neoplasm as a single primary when both a chronic (CLL/SLL) and an acute neoplasm (diffuse large B-cell lymphoma (DLBCL)) are diagnosed simultaneously there is documentation of only one positive bone marrow biopsy, lymph node biopsy or tissue biopsy.
