Multiple Primaries (Pre-2007)/Histology (Pre-2007)--Lung: How is histology coded for the tumor(s) that exist if a left upper lobe of lung resection final diagnosis states the patient has a moderately differentiated adenocarcinoma and the path indicates there are "multiple carcinoid tumorlets"?
For tumors diagnosed prior to 2007:
Histology is coded 8140/3 [adenocarcinoma]. This is one reportable tumor of the left lung. According to our pathologist consultant, the tumorlets are collections of cells which appear to be of neuroendocrine origin, but are not malignant.
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.
Primary site/Histology--Heme & Lymphoid Neoplasms: Should the primary site and histology codes be updated when a patient with a history in 2005 of a bone marrow diagnosis of chronic lymphocytic leukemia later presents in 2010 with lymph node biopsy diagnosis of small B-cell lymphocytic leukemia?
Per Rule M2, this is a single primary because there is a single histology. Code histology to 9823/3 [CLL/SLL]/
The distinction of CLL vs. SLL cannot be made on bone marrow biopsy in isolation. The pathologist cannot make a diagnosis of CLL vs SLL without having peripheral blood counts available for review. If the patient was treated for CLL in the past, that may alter the peripheral counts seen in 2010 (e.g., lymphocytosis). The distinguishing feature is peripheral lymphocytosis in CLL (not seen in SLL). The disease looks the same and both will often have bone marrow involvement and lymph node involvement. If the patient had true CLL in 2005, then any subsequent lymph node (or other) biopsy consistent with CLL/SLL remains consistent with the original diagnosis of CLL. I would not change the original CLL code.
I agree with the previous response. We have to assume the 2005 diagnosis included a peripheral blood supporting that diagnosis. Otherwise, CLL and SLL look the same in nodes and marrow. The interplay between the two "diseases" is expected. This is why they are considered a single disease.

Scope of Regional Lymph Node Surgery: If a named regional lymph node is aspirated should this field be coded to 1 [Regional lymph node removed, NOS], as is stated on page 127 of the SEER Program Code Manual, or should this field be coded to a more specific code when that is available (e.g. Lung primary code 3 [Ipsilateral mediastinal and/or subcarinal nodes])?
For cases diagnosed 1/1/2003 and after: A generic scheme was created for the Scope of Regional Lymph Node Surgery field. As a result, there no longer are codes available that represent specific named lymph node chains. Code aspiration of a lymph node to 1 [Biopsy or aspiration of regional lymph node, NOS].
Reportability/Diagnostic Confirmation: If a physician signs a case out as "precancerous melanosis of the face" (8741/2) and there is no microscopic confirmation of the disease, is thisĀ a reportable clinical diagnosis?
This case is reportable because the diagnosis of precancerous melanosis was stated by a recognized medical practitioner. Precancerous melanosis meets the reportable diagnosis criteria (See 2007 SEER Manual page 1).
CS Lymph Nodes: Are positive right superficial inguinal lymph nodes coded to 30 (which is the case for anal canal primaries) or 31 (which is the case for anus primaries) if the primary is stated to be in the "cloacogenic zone" or is an anorectal primary?
This answer was provided in the context of CSv1 coding guidelines. The response may not be used after your registry database has been converted to CSv2.Assign code 30 for positive unilateral superficial inguinal lymph nodes for cloacogenic primaries. The cloacogenic zone is part of the anal canal.
Histology--Heme & Lymphoid Neoplasms: Should all cases of precursor B acute lymphoblastic leukemia diagnosed 1/1/10 and later with histology coded to 9836/3 have the values changed to 9811/3 per the Heme DB Abstractor Notes section or should they remain coded 9836/3.
For cases diagnosed 2010 and forward, code histology to 9811/3 [B lymphoblastic leukemia/lymphoma, NOS] which is the new classification for pre-BALL. The histology code 9836/3 is obsolete as of 2010 and should not be used for cases with diagnosis date after 12/31/2009.

EOD 2018/Primary tumor--Melanoma: The code and level translations in the Note 4 of Extent of Disease (EOD) Primary Tumor for Melanoma Skin seem incorrect. Please advise.
* Code 000: In situ
* Code 100: Level I (should be level II) (< 0.75 mm Breslow's Depth)
* Code 200: Level II (should be level III) (0.76 mm to 1.50 mm Breslow's Depth)
* Code 300: Level III (should be level IV) (> 1.50 mm Breslow's Depth)
Please see the corrected levels below for the note. Note 4: If a Breslow's depth is given in the pathology report and there is no other indication of involvement, the following guidelines may be used (Note: If a physician documents a different Clark's Level than provided by these guidelines, go with the physician's Clark Level)
Code 000: Level I (In situ)
Code 100: Level II (< 0.75 mm Breslow's Depth)
Code 200: Level III (0.76 mm to 1.50 mm Breslow's Depth)
Primary Site/Histology--Lymphoma: How are these fields coded when the final diagnosis per the pathology report is, "Soft tissue and skeletal muscle, left thigh--Large B cell lymphoma with polyclonal and mature t-cells, involving the soft tissue"?
For cases diagnosed prior to 1/1/2010:Site: C492 [Soft tissue thigh]
Histology: 9680/36 [T-cell rich large B-cell lymphoma]
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.
Histology (Pre-2007)/Diagnostic Confirmation: What code is used to represent the histology that initially presents on uterine curettage as a hydatidiform mole and after pulmonary metastases develop a month later, the clinical diagnosis is "metastatic gestational trophoblastic disease"?
For tumors diagnosed prior to 2007:
Code the Histology field to 9100/3 [Choriocarcinoma]. Gestational trophoblastic neoplasia includes the diagnosis of choriocarcinoma.
Code the Diagnostic Confirmation field to 8 [Clinical diagnosis only] based on the information above. However, if imaging, direct visualization, or another method identified the pulmonary metastases, then code the Diagnostic Confirmation accordingly.
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.
Immunotherapy/Radiation Therapy: Is I-131 labeled immunoglobulin coded as immunotherapy or radiation therapy?
Code treatment with I-131 labeled immunoglobulin as radiotherapy. The primary action is radiotherapeutic. Radioimmunotherapy (RIT) uses antibodies to deliver the radiotherapy to the site of the tumor.
