Primary site--Bladder: What is the primary site for bladder tumor biopsy: invasive adenocarcinoma, enteric type favor urachal origin, stage III
Based on the information provided, code the primary site to urachus (C677). Primary adenocarcinoma of the bladder accounts for less than 1% of all bladder malignancies. Of these, 20–39% are urachal in origin.
Surgery of Primary Site--Skin: What surgery code is used to reflect the amputation of a finger for subungual melanoma?
47 [Wide excision or reexcision of lesion or minor (local) amputation with margins greater than 2cm] is the correct surgery code for amputation of a finger for melanoma.
Reportability--Lung: One of our facilities has a case they are not really sure how to report.
This patient came in for a double lung transplant due to COPD which occurred on 1/27/14. At time of transplant, the team found out the donor hospital had identified a small nodule in the right lower lobe donor lung, which they biopsied and deemed negative. However, the slides were reviewed and felt to represent adenocarcinoma. The team performed a right lower lobe lobectomy of the donor lung before transplanting into the patient.
So, we are not really sure how to handle this case. The adenocarcinoma actually belongs to the donor patient from another hospital, however, they actually didn’t identify it at that facility as their pathology was negative for a malignancy.
This very interesting case is not reportable to either facility. Since the right lower lobe nodule was resected prior to transplantation, the case does not belong to your patient. Ideally, the cancer should be assigned to the donor; however, donor information is confidential.
Surgery of Primary Site--Ovary: How should this field be coded for an ovarian primary when there is a BSO and only the fundus of uterus is removed (not a full hysterectomy)?
Assign surgery code 52 [Bilateral (salpingo-) oophorectomy; WITH hysterectomy]. Code 52 does not exclude a partial hysterectomy.
Histology/Primary site--Heme & Lymphoid Neoplasms: How are these fields coded if a bone marrow biopsy demonstrates diffuse infiltration by B-cell lymphoma/leukemia which consists of medium-sized cells with Burkitt morphology and the flow cytometry has no evidence of leukemia or lymphoma?
This case should be accessioned as one primary. Per Rule PH26, code the primary site to bone marrow (C421) when lymphoma is present only in the bone marrow. (We assumed all available physical exams, scans, and other work-up were negative for lymph node, tissue, or organ involvement.) Histology is coded to 9680/3 [Diffuse large B-cell lymphoma (DLBCL)]. Under the Alternate Names section of the Heme DB, a synonym for DLBCL is B-cell lymphoma, unclassifiable, with features intermediate between diffuse large B-cell lymphoma and Burkitt lymphoma.
SEER*Educate provides training on how to use the Heme Manual and DB.

Multiple Primaries--Lymphoma: How many primaries should be reported when a left tonsil biopsy is diagnosed with marginal zone lymphoma (9699) and a cervical lymph node biopsy is diagnosed with marginal zone lymphoma and grade 3 follicular lymphoma (9699 and 9698)?
For cases diagnosed prior to 1/1/2010:
Abstract two primaries: The first is a marginal zone lymphoma of tonsil and the second is a follicular lymphoma of cervical lymph node. According to the Single versus Subsequent Primaries of Lymphatic and Hematopoietic Diseases (the tri-fold chart), marginal zone lymphoma (9699) and follicular lymphoma (9698) are different primaries.
For cases diagnosed 1/1/10 and later, 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.
Date of Diagnosis: When doing follow-back at nursing homes on DCO cases, we find it difficult to code diagnosis date because the nursing home records are often vague or incomplete. Should the diagnosis date be coded as unknown (excluded from SEER database), the date of death, or the approximate date of diagnosis as reported on the death certificate?
If the nursing home record indicates that the patient had cancer, use the best approximation for date of diagnosis.
If the record says the patient had cancer when admitted, but it does not provide a date of diagnosis, use the date of admission as the date of diagnosis.
If there is no mention of cancer in the nursing home record and/or all work-up in the record is negative, assume the cancer was discovered at autopsy. Use the date of death as the date of diagnosis, and leave as a Death Certificate Only case.
Terminology/Terms of involvement: When the terms "lytic" or "lysis" are used in an imaging study, are they to be interpreted as synonymous with metastasis, or can these terms be used to describe a non-malignant condition?
Although the term "lytic lesion" is often used to describe bone lesions and "tumor lysis" develops in response to systemic therapy, the words are not a part of the SEER list of terms used to describe involvement. Do not code distant metastasis based only on these words.
Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Brain and CNS: How many primaries should be abstracted and should the histology field(s) be coded to 9530/1 [Meningiomatosis, NOS] or 9530/0 [Meningioma, NOS] to represent a case that presents with MRI confirmed multiple meningiomas (e.g., left dura, right parasagittal region, and left frontal lobe)?
For tumors diagnosed prior to 2007:
Abstract this case as two primaries, right and left cerebral meninges. Code the histology for both primaries to 9530/0 [Meningioma, NOS]. Use code 9530/1 [Meningiomatosis, NOS] only when the diagnosis is stated to be meningiomatosis, or multiple meningiomas.
For tumors diagnosed 2007 or later, refer to the MP/H rules. If there are still questions about how this type of tumor should be coded, submit a new question to SINQ and include the difficulties you are encountering in applying the MP/H rules.
