Arimidex has not been approved to treat endometrial cancer. It is not prescribed for pre-menopausal women. Clarify with the physician why the drug was being used. If the physician states Arimidex was given to reduce tumor burden, code as hormone therapy.

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.

For cases diagnosed 2007 or later, accession two primaries, serous carcinoma of the right ovary and serous tubal intraepithelial carcinoma of the left fallopian tube based on the information provided.

The steps used to arrive at this decision are:

Open the Multiple Primary and Histology Coding Rules Manual. Choose one of the three formats (i.e., flowchart, matrix or text) and go to the Other Sites MP rules because neither the ovary nor fallopian tube have site specific rules developed.

Start at the MULTIPLE TUMORS module, Rule M3. The rules are intended to be reviewed in consecutive order within a module. The patient has multiple tumors with ICD-O-3 topography codes that are different at the third character (Cxx) and therefore this case should be accessioned as a multiple primary.

It could be helpful to know the extent of involvement noted prior to neoadjuvant therapy and debulking surgery. For example, if the patient had widely metastatic disease throughout the entire pelvis prior to the initiation of treatment, the answer may have been different.

Per Rule M14, accession this is a single primary. Per PH27, code the primary site to C809 [unknown} and per PH1, code the histology to 9680/3 [diffuse large B-cell lymphoma].

Per Rule M14, abstract as a single primary when post-transplant lymphoproliferative disorder is diagnosed simultaneously with any B-cell lymphoma, T-cell lymphoma, Hodgkin lymphoma or plasmacytoma/myeloma.

Per PH1, code the histology of the accompanying lymphoma or plasmacytoma/myeloma when the diagnoses of post-transplant lymphoproliferative disorder and any B-cell lymphoma, T-cell lymphoma, Hodgkin lymphoma, or plasmacytoma/myeloma occur simultaneously.

Per PH27, code the primary site to C809 [unknown primary site] because there is no lymph node involvement, but there is involvement of two extranodal sites.

Secondary polycythemia vera is not reportable. See Appendix F.

Primary polycythemia vera is a condition in which there is an overproduction of blood cells due to a neoplastic process. Secondary polycythemia vera is an over production of red blood cells caused by a co-morbidity, in this case, volume depletion.

This case should be accessioned as two primaries per Rule M11. Code the histology of one primary to 9680/3 [diffuse large B-cell lymphoma], the acute neoplasm. Code the histology for the second primary to 9823/3 [chronic lymphocytic leukemia/small lymphocytic lymphoma], the chronic neoplasm.

Per Rule M11, abstract as multiple primaries when both a chronic and acute neoplasm are diagnosed simultaneously or less than or equal to 21 days apart AND there is documentation of two pathology specimens, one confirming the chronic neoplasm (bone marrow biopsy) and one confirming the acute neoplasm (stomach biopsy).

Per Rule PH30, use the Heme DB to determine the primary site and histology when rules PH1-PH29 do not apply. Code the primary site to C419 [bone, NOS], assuming there are multiple bones involved in this case. If only one bone is involved, code the primary site to the specified bone.

In the Abstractor Notes section in the Heme DB, it indicates the primary site may differ for LCH in the solitary disease and multisystem disease. This patient has multisystem disease with involvement of the bone, liver, spleen and retroperitoneum. The most common sites for multisystem involvement include three of the four above sites (bone, liver, and spleen).

Determine the primary site based on the knowledge of the usual sites of involvement for this disease, the actual sites of involvement for the case presented, and identifying which sites of involvement are likely metastatic and which are the potential primary sites. There are two potential primary sites of involvement: the bone and the retroperitoneum. Bone is a common site of involvement for LCH while the retroperitoneum is not. Code the primary site to C419 [bone, NOS] because multiple bones are involved for this patient and bone is the most common site for LCH based on the documentation in the Abstractor Notes.

The spleen and liver are typically not primary sites for this disease process. They become involved when there is multisystem involvement because they filter the blood. They are typically sites of metastatic involvement. This information will be added to the ABSTRACTOR NOTE section.

Per Rule PH25, code the primary site of the diffuse large B-cell lymphoma to C649 (kidneys) and laterality to 4 (bilateral). Per PH25, code the primary site to the organ when a lymphoma is present in an and that . This patient had involvement of an organ (bilateral kidneys) as well as regional lymph nodes for that organ. The retroperitoneal lymph nodes are regional for the kidney.

The diffuse large B-cell lymphoma is an acute transformation of the chronic lymphocytic leukemia. Because the DLBCL occurred more than 21 days after the CLL, it is a new primary per Rule M10.

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.

Per Appendix F, monoclonal B-lymphocytosis of uncertain significance (MLUS) is not reportable.

Some papers point out that a lymphocyte count less than five thousand is equivalent to monoclonal B-lymphocytosis of uncertain significance (MLUS) or monoclonal B-cell lymphocytosis (MBL). A lymphocyte count of five to thirty thousand could be smoldering chronic lymphocytic leukemia (CLL). The diagnosis of MLUS is a benign process that does not meet the criteria for CLL.
