20031001 EOD-Extension/EOD-Lymph Nodes--Cervix: How do you code these fields when the cancer extended to the pelvic wall and there are periaortic LN metastases?

For cases diagnosed 1998-2003:

Assign extension code 65 for contiguous (direct) extension of tumor from the cervix to the pelvic wall. Assign extension code 85 only if the pelvic wall is involved with discontinuous extension from the cervix; i.e., the cervical tumor spread indirectly (through lymph or vascular channels) to the pelvic wall. Code the pelvic wall involvement in the Extension field and the periaortic lymph node involvement in the Lymph Node field. When the computer does the algorithm, it will look at the periaortic lymph nodes and report the summary stage as distant and the TNM stage group as IV because periarotic nodes are M1. Do not code the periaortic lymph nodes in both fields. This is stage IV, distant disease, due to the periaortic lymph node involvement (EOD lymph nodes code 6).

Multiple Primaries (Pre-2007)--Trachea/Lung: Would synchronous lesions, of the same histology, diagnosed in the right upper lobe of the lung and trachea be a single primary when the physician feels they are two separate primaries?

For tumors diagnosed prior to 2007:

According to SEER rules, abstract as one primary because although these sites have separate topography codes in ICD-O-3, they were coded to the same three-digit topography code in the first edition of ICD-O (SEER Program Code Manual, 3rd Edition, page 8, Exception B). Simultaneous lesions of the same histology in trachea and lung are one primary. Code the primary site to C399 [Ill-defined sites within respiratory system].

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.

 2003
20031145 EOD-Extension--Head & Neck: Is this field coded 10 [Invasive tumor confined to one of the following subsites: interior wall, one lateral wall, posterior wall] or 30 [Localized, NOS] for tonsillar primary when there is no mention of involvement of surrounding structures? See Description. Site is stated to be "left tonsil" and was coded to site C099. "The lesion is admixed in tonsillar tissue." No surrounding structures are stated to be involved. Is it logical to assume that since code C099 includes the palantine tonsils and the palatine tonsils are on the lateral wall and since no other areas are stated to be involved that extension code 10 [confined to one lateral wall] would be more appropriate than code 30 [localized NOS]? For cases diagnosed 1998-2003: Code EOD-extension for the case example to 10 [Invasive tumor confined to one of the following subsites: anterior wall, one lateral wall, posterior wall]. The tonsil lies in a pocket on the wall (tonsillar fossa), so you know it is confined to the wall. 2003
20031172 Hormone Therapy--Breast: Should hormonal therapy be coded as administered, when the physician states "Tamioxifen was given as a prescription?" Yes, based on the prescription for Tamoxifen, code Hormone Therapy as administered. 2003

EOD-Extension--Kaposi Sarcoma: Is a "markedly enlarged spleen" involvement for cases of Kaposi Sarcoma?

For cases diagnosed 1998-2003: No. Splenomegaly is not synonymous with "extension to" or "involvement of" the spleen in Kaposi's sarcoma. Look for a definite statement of Kaposi's lesion(s) involving the spleen.

 2003
20031051 Histology (Pre-2007)/Sarcoma: What code is used to represent the histology "Ewing's Sarcoma/Primitive Neuroectodermal Tumor (PNET)"? See Description. A comment on one path report states "some authors consider both Ewing's & PNET to be the same biologic entity given that they share the same translocation between chromosomes 11 & 22." The pathologists at our children's hospital agree with this statement and contend that the two should have the same histologic code.

For tumors diagnosed prior to 2007:

Code histology as 9260/3, Ewing sarcoma. Ewing sarcoma is a specific histology on the continuum of primitive neuroectodermal tumors. Code Ewing sarcoma as it is more specific than PNET, NOS.

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.

20031167 Primary Site/Histology--CLL/SLL: How should these fields be coded when the pathological diagnosis of chronic lymphocytic leukemia/small lymphocytic lymphoma is made on bone marrow biopsy only but scans show lymphadenopathy? See Description.

What histology would we give these two examples?

1. Bone marrow bx: CLL/SLL. CT chest/abdomen: Mediastinal and retroperitoneal adenopathy.

2. Bone marrow bx: CLL/SLL. CT chest/abdomen: Mediastinal and retroperitoneal adenopathy suspicious for lymphoma.

For cases diagnosed prior to 1/1/2010:If a lymph node or other solid tissue is involved initially, code to SLL. For lymphoma, any mention of lymph nodes is indicative of involvement. Involvement does not have to be proven pathologically in order to code to Small Lymphocytic Lymphoma (SLL). Code both of the examples to SLL.

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.

EOD-Lymph Nodes--Head & Neck: If a pre-treatment description of a chain of lymph nodes doesn't meet the criteria for involvement but the post-treatment description of the same chain of lymph nodes does, should those nodes be counted as involved in coding EOD? See Description.

(Primary site = larynx)

9/12/02 CT neck showed right cervical chain adenopathy. After chemotherapy, an 11/18/02 CT soft tissue of neck showed decrease in size by 50% of what was probably necrotic metastatic node to right mandibular angle.

The term "lymphadenopathy" should be ignored when determining involvement of lymph nodes per SEER. In this case, a probable necrotic metastatic node is mentioned in a subsequent CT taken after treatment.

Should lymph node involvement be coded to 9 based on the 9/12/02 CT or coded to 4 because of the mention of a decrease in size of what was probably a metatastic node on the 11/18/03 CT?

For cases diagnosed 1998-2003, code EOD using the best information available. In this example, the post-treatment description of lymph nodes. A post-treatment description of lymph nodes can be used to code lymph node involvement in the absence of disease progression. Pre-operative treatment does not affect lymph node involvement.

Case example: Code lymph nodes as involved (codes 1-4 depending on size and number) based on the later CT report.

 2003
20031179 EOD-Extension--Stomach: How is this field coded for a stomach primary that has metastases to "Sister Mary Joseph's Nodes?"

For cases diagnosed 1998-2003: For a stomach primary, code extension to 70 [Abdominal wall]. Sister Mary Joseph's nodule is a cutaneous umbilical metastasis most commonly from an intra-abdominal primary.

This rare form of cutaneous umbilical metastasis results from spread of tumor within the falciform ligament. The umbilicus is part of the abdominal wall.

Histology--Hematopoietic, NOS: Because histology 9895/3 [Acute myeloid leukemia with multilineage dysplasia] was recognized as a distinct entity by WHO with too few cases of the subtypes [with or without prior MDS] to warrant separate histology codes for each, should the wording for the non-bold definitions in ICD-O-3 be changed to the following in both the alpha and numeric sections? See Description.

AML with multilineage dysplasia and prior MDS

AML with multilineage dysplasia and without prior MDS

How do we code histology for the following case of AML?

Patient was admitted for profound anemia and thrombocytopenia with

no immediate explanation. Path final diagnosis on bone marrow biopsy: acute myelogenous leukemia (AML). Per micro description: findings are

characteristic of AML that appears to be arising within the context of a myelodysplastic syndrome. The discharge diagnosis (2 days after bone marrow biopsy) read: myelodysplastic syndrome with profound anemia and

thrombocytopenia.

Do we code the histology per the final path diagnosis (code 9861/3)?

Using the current version of ICD-O-3, we could arrive at a histology code of 9895/3 based on the micro findings of AML with prior myelodysplastic syndrome. However, per the above-mentioned SEER e-mail, we would not because there was no mention of multilineage dysplasia.

For cases diagnosed prior to 1/1/2010:To assign code 9895, it is important that the diagnosis includes "multilineage dysplasia." Use code 9895 when the diagnosis is with or without prior (not concurrent) myelodysplastic syndrome AND multilineage dysplasia. Acute myeloid leukemia without prior myelodysplastic syndrome and without multilineage dysplasia is coded 9861 [Acute myeloid leukemia, NOS].

Although the wording of 9895 cannot be changed, coders can make a note that the synonyms are intended to include:

-Acute myeloid leukemia WITH multilineage dysplasia with prior myelodysplastic syndrome

and

-Acute myeloid leukemia WITH multilineage dysplasia without prior myelodysplastic syndrome.

The histology code for the case example is 9861/3 [Acute myeloid leukemia, NOS].

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.
