The term "coagulable state" is not reportable. This is not a a neoplasm. The term means capable of coagulating or capable of becoming thick. There are neoplasms, such as polycythemia vera, in which the blood becomes thick; however, you must have an actual reportable diagnosis in order to accession the case.

Code the primary site to C421 [bone marrow] and the histology to 9680/3 [diffuse large B-cell lymphoma] per Rule PH26. B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is listed under Alternative Names section of the Heme BD for DLBCL [9680/3]. This patient has bone marrow involvement only. The Note for Rule PH26 instructs one to code the primary site to the bone marrow when all physical exams or work-up were negative for lymph node, tissue, or organ involvement OR no other work-up was done.

The histology is not coded 9684/3 [malignant lymphoma, large B-cell, diffuse, immunoblastic, NOS]. This histology code became obsolete in 1/1/2010. Diffuse large B-cell lymphoma, immunoblastic variant is also listed under Alternative Names section of the Heme BD for DLBCL.

Code the primary site to C774 [inguinal lymph nodes] per Rule PH18. Code the primary site to inguinal lymph nodes [C774] when the site of lymphoma is described only as an inguinal mass. Groin lymph nodes are inguinal lymph nodes.

The diffuse large B-cell lymphoma diagnosed by right tibia biopsy is not a new primary per rule M7 because the histology of the history only case would be coded as 9590/3 [lymphoma, NOS]. No more specific histology is known for the initial diagnosis. Accession a single primary when a more specific histology [DLBCL] is diagnosed after the NOS ONLY histology when the Heme DB Multiple Primaries Calculator confirms the NOS and the more specific histology are the same primary. The right tibial involvement is not used to code the primary site because the patient had chemotherapy for this groin lymphoma prior to diagnosis of DLBCL.

Per Appendix F, plasma cell neoplasm is not a synonym for multiple myeloma. Plasma cell neoplasm is a disorder that has an abnormal number of plasma cells. MGUS is such a disorder, but it is not reportable.

According to WHO, 'Plasma cell neoplasms' is the umbrella term that includes MGUS, plasma cell myeloma, solitary plasmacytoma of bone, immunoglobulin deposition diseases, extraosseous plasmacytoma, and osteosclerotic myeloma. Of these, only plasma cell myeloma, solitary plasmacytoma of bone, and extraosseous plasmacytoma are reportable.

Note: This terminology was added to the 2012 Hematopoietic Manual and Database for 1/1/2012. This should not have been added. If the only diagnosis is "plasma cell neoplasm," this is not reportable. If the diagnosis is "plasma cell neoplasm c/w multiple myeloma (or another reportable disease)," then it would be a reportable disease.

Hemangioma, NOS (9120/0) and cavernous hemangioma (9121/0) arising in the dura and parenchyma of the brain/CNS are reportable.

Venous angiomas (9122/0) are not reportable wherever they arise. The primary site for venous hemangioma arising in the brain is blood vessel (C490). The combination of 9122/0 and C490 is not reportable. This is a venous abnormality. Previously called venous angiomas, these are currently referred to as a developmental venous anomalies (DVA).

There has been a change in coding practice based on a change in clinical classification of leukemia/lymphomas. In the past, we did, indeed, default to lymphoma when both tissue and bone marrow were involved. The problem was that when only bone marrow was involved, the case was coded to leukemia with a primary site of bone marrow. When lymphoma symptoms developed later, there was a lot of inconsistency in how registries handled these cases. Some coded a new primary "lymphoma;" while others ignored the lymphoma calling it progression.

The clinical world, including the hematopoietic experts in the World Health Organization and the Inter-Lymph Consortium, agreed that for certain neoplasms (CLL/SLL being one of them) it was not useful or practical to code the leukemia and lymphoma separately OR to capture only one of the neoplasms (because these neoplasms almost always progress to lymphoma); so new codes for the leukemia/lymphoma were developed. According to the experts, 9823/3 most accurately portrays the neoplastic process for the neoplasms assigned to a lymphoma/leukemia code.

Accession two primaries, adenocarcinoma [8140/3] of the prostate [C619], followed by small cell (neuroendocrine) carcinoma [8041/3] of the prostate [C619] for each of the examples given per Rule M10.

In each case, the second histology (because it is not adenocarcinoma) is a new prostate primary. Small cell carcinoma and small cell neuroendocrine carcinoma are not adenocarcinomas. As a result they are not covered by Rule M3.

This case is not reportable. Neither plasma cell dyscrasia nor MGUS are reportable. Smoldering myeloma was given as a possible diagnosis, but never confirmed.

Code the histology to 9735/3 [plasmablastic lymphoma] and the primary site to C809 [unknown] per Rule PH27.

Code the histology specified when the only histology for the case is preceded by ambiguous terminology. For this case, code the histology to plasmablastic lymphoma because it is the only histology mentioned in the diagnosis.

Per the Heme DB Abstractor Notes section for plasmablastic lymphoma, most patients present with Stage III-IV disease. The positive pleural fluid is likely due to advanced disease. In the absence of any other information for this case, Rule PH27 applies, "Code primary site to unknown primary site C809 when there is no evidence of lymphoma in lymph nodes AND the physician documents in the medical record that he/she suspects that the lymphoma originates in an organ(s) OR multiple organ involvement without any nodal involvement."

For cases diagnosed 2007 or later, the correct histology code is 8244/3 [composite carcinoid]. The steps used to arrive at this decision 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 Colon Histology rules because site specific rules have been developed for this primary.

Step 2: Start at the SINGLE TUMOR module, rule H1. The rules are intended to be reviewed in consecutive order within a module. Stop at rule H9. Code the histology as 8244/3 [composite carcinoid] when the diagnosis is adenocarcinoma and carcinoid tumor.

Neuroendocrine tumor, grade 1 (G1) is synonymous with carcinoid tumor [8240/3] for the purpose of rule H9.
