This is a reportable diagnosis and should be accessioned with the histology coded to 9975/3 [myelodysplastic/myeloproliferative neoplasm, unclassifiable].

The term is a reportable ambiguous term per the Hematopoietic Coding Manual (Case Reportability Instructions, Rule 4). Also, the patient was treated for a myeloproliferative disorder, making this a reportable clinical diagnosis per the SEER Manual (Reportability, Pg 4, Exception 1).

Myeloproliferative disorder is synonymous with myeloproliferative disease. Myeloproliferative disease is listed as an alternate name for myelodysplastic/myeloproliferative neoplasm, unclassifiable.

Per Rule M15, accession two primaries. According to Rule M15, use the multiple primaries calculator to determine the number of primaries for all cases that do not meet the criteria of M1-M14. Per the calculator, this scenario represents two primaries.

Assuming the only area of involvement is the large intestine, code the histology to 9680/3 [diffuse Large B-Cell Lymphoma] and per Rule PH24 code the primary site to C189 [colon, NOS]. According to PH24, one is to code the primary site to the organ when lymphoma is present only in an organ.

Rule PH26 applies to the second primary. Assuming the only area of involvement is the bone marrow, code the histology to 9702/3 [peripheral T-cell lymphoma] and code the primary site to C421 [bone marrow]. According to PH26, one is to code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow.

Rule M4 does not apply for this case. Rule M4 applied when you have two or more types of non-Hodgkin lymphoma in the same anatomic location. That is not the case in this scenario.

Based on the information provided, this case of adult granulosa cell tumor is malignant and reportable. According to our expert pathologist consultant, "though granulosa cell tumor NOS/ adult NOS is 8620/1, the presence of peritoneal implants or metastases, and/or lymph node metastases indicates the tumor is malignant, and it should be coded /3."

Note that the presence of implants or metastases does not indicate malignancy in the case of low malignant potential ovarian epithelial tumors. Our path expert explains "in contrast, by convention the behavior of borderline/LMP ovarian epithelial tumors is determined by the ovarian primary, and is /1, even though there may be peritoneal implants/metastases, or metastatic disease in lymph nodes. The treatment may vary in these circumstances, but to my knowledge the decision as to the tumor designation remains based on the primary tumor."

Assign code 8502/3 [secretory carcinoma of breast].

Acinar carcinoma [8550/3] describes a very typical type of salivary gland tumor only. This histology code does not adequately capture the histology in this case which describes a secretory carcinoma that is similar to mammary cancer. Both of these elements are reflected in the histology code 8502/3 [secretory carcinoma of breast].

No. Per Appendix F, erythrocytosis of an unknown cause is not reportable.

The diagnosis must state "erythrocytosis megalosplenic" to be reportable (9950/3).

Code the Systemic/Surgery Sequence to 7 [surgery both before and after systemic therapy] for this case.

The answers to SINQ 20091055 and 20071102 do not apply to a case diagnosed in 2013. These answers were posted prior to code 7 becoming effective in 2012.

This case is reportable if the patient was treated for plasmacytoma. When the physician calls the case plasmacytoma and treats the patient accordingly, report the case.

See Case Reportability Instructions #6: Report the case when there is a clinical diagnosis (physician's statement) of a reportable hematopoietic or lymphoid neoplasm.

Note 1: The clinical diagnosis may be a final diagnosis found within the medical record or recorded on a scan (CT, MRI for example)

Note 2: Report the case even if the diagnostic tests are equivocal. A number of hematopoietic neoplasms are "diagnoses of exclusion" in which the diagnostic tests are equivocal and the physician makes the clinical diagnosis based on the equivocal tests and the clinical picture. See the Heme DB for definitive diagnostic methods for the specific neoplasm being abstracted.

Code the grade to 6 [B-cell] for all cases of 9811/3 [B lymphoblastic leukemia/lymphoma] per Rule G3 in the Heme Manual.

Acute lymphoblastic leukemia, NOS [9835/3] is an obsolete code and cannot be used for cases diagnosed 2010 and later. The Heme DB indicates the correct histology code is 9811/3 and grade 6 [B-cell] for cases diagnosed 2010 and later.

For cases of acute lymphoblastic lymphoma, NOS [9835/3] diagnosed prior to 2010, use the pathology report information to code the grade. Code the grade as 9 [unknown] if the pathology report does not specify the grade.

The following are not alternative names for any reportable disease process:

• Essential thrombocytopenia

The diagnosis of essential thrombocythemia is based on blood counts, but is usually a diagnosis made by excluding other myelodysplastic disorders. The following are reportable disease processes:

• Essential thrombocythemia (9962/3)

This is a reportable primary. Langerhans cell histiocytosis (LCH) [9751/3] is a reportable neoplasm.

The term "self-healing" means that the neoplasm regressed without treatment. This is a known phenomenon.
