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.

This is a single primary. The diagnosis date is coded to 2003 and the histology is mucinous cystadenocarcinoma [8470/3]. The bone, abdominal tissue and omentum are metastatic sites. The MP/H Rules do not apply to metastases.

This is a case where an invasive or microinvasive element was missed in the original pathology. Because the entire tumor was not sectioned and placed on slides, the pathologist used their expertise when sectioning and selecting tissue to be examined. It is not a matter of poor judgment, just a fact that it is impossible to review the tissue from the entire tumor. The behavior must be changed to malignant [/3].

There is no time limit set to update histology to a more specific disease process if a patient has an initial NOS histology identified. Unlike solid tumors, hematopoietic and lymphoid neoplasms may take a year or more to manifest the specific disease. This is simply a part of the "disease characteristics."

Abstract a single primary per M2, a single histology represents a single primary. Code the histology to 9983/3 [MDS/RAEB-2.]

The Heme DB guidelines were interpreted correctly. MDS/RAEB can transform to AML and would be two separate primaries there had also been a reportable diagnosis of AML. The 7/2/2010 peripheral blood showed MDS and a clonal abnormality that was "compatible with MDS/AML." The 10/7/2010 bone marrow biopsy showed only RAEB-2 with "evolution towards AML with myelodysplasia related changes." Ambiguous terminology is only used to help determine reportability; it not used to code a more specific histology. In this case, there was only ambiguous terminology used to describe the AML.

It is important to understand the implication of incorrectly assigning histology codes for hematopoietic and lymphoid neoplasm using ambiguous terminology. Using this case as an example, the patient was not treated until three months after the 7/2/2010 peripheral blood diagnosis of MDS compatible with MDS/AML. The medical literature indicates that AML, if left untreated, is usually fatal within 1-3 months. The treatment given 10/6/2010, 3 months after the "compatible with" diagnosis, was a drug used to treat MDS and not AML.

The other issue with this case is that the bone marrow examination, which is more reliable than peripheral blood, showed only "evolution towards AML." This means that the bone marrow is exhibiting the changes seen in the final stages of MDS prior to progression to AML. Wait for a definitive diagnosis of AML and/or treatment for AML before abstracting the second primary.

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.

Do not accession the 2011 diagnosis of Langerhans cell histiocytosis. In the Abstractor Notes section of the Heme DB is indicates this is reportable for cases diagnosed 2010 and later. However, this patient was initially diagnosed prior to 2010 when it was not a reportable disease process.

The histology code for Langerhans cell histiocytosis has not changed over time. The histology code for cases of Langerhans cell histiocytosis diagnosed prior to 2010 was also 9751 per the ICD-O-3. The only change since 2010 was in the behavior code for this disease. It changed from borderline [/1] to malignant [/3]. The current disease represents a recurrence of the previous Langerhans cell histiocytosis. Per the Multiple Primary rules, Rule M2, a single histology is a single primary. The original diagnosis was made before the disease was reportable; do not report the disease recurrence or progression as a new primary.

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.

Code the diagnostic confirmation to 8 [clinical diagnosis only] in this case.

Per the Heme DB, JAK-2 is only positive in about 50% of essential thrombocythemia (ET) patients. In addition, a positive JAK-2 test does not identify the type of myeloproliferative disease (MPN) the patient has, only the presence or absence of the JAK-2 mutation.

The WHO guidelines for diagnosing ET are: elevated platelet count over months and the elimination of other causes for an elevated platelet count (such as polycythemia vera (PV), chronic myelogenous leukemia (CML), idiopathic myelofibrosis, or myelodysplastic syndrome (MDS)); the absence of Philadelphia chromosome, BCR/ABL fusion gene; and del(5q), t(3;3)(q21;26),inv(3)(q21q26)).

Subsequently, the physician rules out any underlying causes of thrombocytosis such as an inflammation or infection, other neoplasms, and prior splenectomy.

Ultimately, there is a diagnosis of exclusion. In other words, all other causes for the elevated platelet count have been excluded. The physician assembles the information from the blood counts, bone marrow and JAK-2 testing along with the information that excludes all other diseases and makes a clinical diagnosis of ET.

Amyloidosis, NOS is not reportable. It is listed in Appendix F of the Heme Manual on the Non-Reportable List for Hematopoietic Diseases.

Amyloidosis (AL) is term that refers to a group of conditions that include benign conditions (e.g., found in the pancreas of type II diabetes patients and in the brain lesions of Alzheimer patients) as well as in malignant diseases (e.g., AL found in multiple myeloma and ACal (calcitonin) found in medullary carcinoma of the thyroid). Amyliodosis, NOS is not a term that equates to a malignant diagnosis.

Check the medical record to see if this disease process is designated as either AL or ACal. There should be a malignant diagnosis such as multiple myeloma or medullary carcinoma of the thyroid in such cases rather than simply a diagnosis of amyloidosis. The malignancy needs to be coded, not the symptoms of the disease process.

This is a reportable case. Code the histology as malignant gastrinoma [8153/3].

Gastrinomas are usually malignant. This one is apparently present in a metastatic site (periportal lymph node) which confirms the malignancy.

Code the histology to duct and lobular carcinoma in situ [8522/2].

For cases diagnosed 2007 and later, the steps used to arrive at this decision are:

Go to the Breast MP rules found in the Multiple Primary and Histology Coding Rules Manual. Start at the MULTIPLE TUMORS Module Rule M4 because the patient had multiple foci of DCIS and a separate, single focus of LCIS. The rules are intended to be reviewed in consecutive order within the applicable Module. Tumors that are lobular and duct are a single primary.

Go to the Breast Histology rules found in the Multiple Primary and Histology Coding Rules Manual. Start at the MULTIPLE TUMORS ABSTRACTED AS A SINGLE PRIMARY Module Rule H20 because the patient has multiple foci of DCIS and LCIS. Code the histology as 8522/2 [duct and lobular carcinoma in situ] when there is any combination of lobular [8520] and duct carcinoma.

The DCIS and LCIS are separate tumors. The DCIS was removed by the lumpectomy and the LCIS by the mastectomy. The most representative specimen for the DCIS is the lumpectomy. The most representative specimen for the LCIS is the mastectomy. Both pathology reports must be used in this case to determine the histology.
