Histology/Date of Diagnosis--Hematopoietic, NOS: What code is used to represent histology for a June 2001 diagnosis of "myelodysplastic syndrome" followed by a September 2001 bone marrow biopsy diagnosis of "myelodysplasia evolving into an acute leukemic state"?
For cases diagnosed prior to 1/1/2010:
Code the Histology field to 9989/3 [myelodysplastic syndrome] and the Date of Diagnosis field to June 2001.
For cases diagnosed 2010 forward, refer to the Hematopoietic and Lymphoid Neoplasm Case Reportability and Coding Manual and the Hematopoietic Database (Hematopoietic DB) provided by SEER on its website to research your question. If those resources do not adequately address your issue, submit a new question to SINQ.
Reason for No Cancer-Directed Surgery--Lung: How do you code this field for a lung primary that presents with metastasis to the bone and brain in which the oncologist's treatment plan includes only radiation and chemotherapy?
Code the Reason for No Cancer-Directed Surgery field to 1 [Cancer-Directed Surgery Not Recommended].
Reportability/Ambiguous Terminology--Esophagus: Is a case with a biopsy diagnosis of "... focal areas suspicious for adenocarcinoma in situ change" reportable if the diagnosis on the partial esophagectomy specimen only includes the phrase "... with foci of high grade dysplasia; no invasive carcinoma identified"?
The case is not reportable.
The biopsy with a suspicious result (suspicious for adenocarcinoma) was disproven by the esophagectomy.
Scope of Regional Lymph Node Surgery/EOD-Number of Regional Nodes Examined: What codes is used to represent these fields when the surgeon states that a "lymph node dissection" was done, but no nodes are identified in the pathology report?
For cases diagnosed 1/1/2003 and after: Code the Scope of Regional Lymph Node Surgery field to 3 [Number of regional lymph nodes removed unknown or not stated; regional lymph nodes removed, NOS] and code the EOD-Number of Regional Nodes Examined field to 00 [No nodes examined].
The surgery fields reflect the procedures the physician performed. The EOD fields reflect the results of those procedures.
Reportability--Brain and CNS: Is Tuberculum sellae meningioma reportable? Is it same as sphenoidale meningioma?
Path: Brain tuberculum tumor resection: Meningioma, WHO grade I.
Revised answer based on ST rules
Yes, a Tuberculum sella meningioma is reportable if diagnosed 2004 or later. Code the primary site C700, cerebral meninges. It is a meningioma originating from the meninges of the Tuberculum sellae, which is part of the sphenoid bone.
MP/H Rules/Histology--Bladder: What is the correct histology code for a diagnosis of urothelial plasmacytoma carcinoma of the bladder per pathology report?
Assign code 8120/3, urothelial carcinoma, NOS, to urothelial plasmacytoma carcinoma of the bladder. The WHO classification describes plasmacytoid variants of urothelial carcinoma. There is no specific ICD-O-3 code for these variants; however, and 8120/3 must be used.
Primary Site--Heme & Lymphoid Neoplasms: How is the primary site coded for a B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma when a biopsy of the paraspinal muscle and epidural tissue is positive, but there is no indication of lymph node involvement in the chart?
Code the primary site to soft tissue of the back, NOS [C496] per Rule PH24 and the Abstractor Notes in the Heme DB for B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.
Code the primary site to the organ when lymphoma is present only in an organ. The lesion is described as epidural (tissue surrounding the dura) and involving paraspinal muscle, NOS. Both are connective or other soft tissues of the trunk, NOS [C496].
B-cell lymphoma intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma is a synonym for DLBCL 9680/3. When there is no primary site listed in the Heme DB, go to the Abstractor Notes. In the Abstractor Notes section it states that patients present with lymphadenopathy OR mass lesions in extranodal sites.

Histology: What is the histology code for a soft tissue thigh mass that was diagnosed as Ewing sarcoma/PNET, primitive neuroectodermal tumor?
The histologies stated for this case are Ewing sarcoma (9260) and PNET, primitive neuroectodermal tumor,(9364)*. Use the Other Site Rules, starting with H8. Stop at H17 and assign the higher histology code -- 9364/3 [Peripheral neuroectodermal tumor].
*The term "PNET" is used for two different tumors. One is primitive neuroectodermal tumor (9473) and pertains to brain tumors per ICD-O-3 review. The other is peripheral primitive neuroectodermal tumor (pNET or PPNET 9364) and pertains to bone or soft tissue tumors. This case is stated to be soft tissue and Ewing sarcoma, so it is 9364 rather than 9473.
Histology: Is there any guidance on using STRATA Oncology testing (molecular tumor profiling tests), such as StrataNGS and StrataEXP, to code SSDIs, histology, etc? I do not see anything in STR, SEER Program Manual, SINQ, or CAnswerForum. We are seeing the testing with our 2021 paths.
We recommend that you do not use information from these molecular tumor profiling tests until they become a standard diagnostic tool. If/when that happens, we will add information to the various manuals.
