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.

20031076 EOD-Size of Primary Tumor--Prostate: Is this field coded to the size of a hypoechoic mass identified on a TRUS when there is no tumor size from the prostatectomy specimen? For cases diagnosed 1998-2003: Ultrasound measurement of a malignancy can be used to code EOD-Size of Primary Tumor. Information on tumor size taken from imaging/radiographic techniques has low priority, just above physical examination. 2003

EOD-Size of Primary Tumor: Can the term "filling defect" be used to code tumor size? See Description.

Site: Bladder

CT abd/pelvis: 4 cm filling defect of the bladder encasing jetstream of distal ureter. 2-3 cm lesion may be extension to bladder. KUB: 3-4 cm filling defect within bladder.

Cystoscopy: large bladder tumor with small tumor extending out of the large tumor.

OP Findings: Large tumor on right of bladder extending from bladder neck lateral and posterior

Pathology: TURB: High grade TCC, Grade III with focal lamina propria invasion.

For tumors diagnosed 1998-2003:

Information on size from imaging/radiographic techniques can be used to code size when there is no more specific size information from a pathology or operative report, but it should be taken as low priority, just above a physical exam.

The term "filling defect" from a CT or KUB may be used to code tumor size for bladder in the absence of more reliable size information from path, operative or endoscopic reports.

20031113 Primary site/Surgery of Primary Site/Surgical Procedure of Other Site--Unknown & ill-defined site: How are these fields coded for this type of primary site when a tumor excision and lymph node dissection is performed? See Description. Patient had a left parotidectomy w/ neck dissection in 02/2003. Findings showed a 10x5cm neck mass over the angle of the mandible as well as a 1.5 cm level 4 mass. Path showed invasive mod diff squamous cell ca. with posterior soft tissue margin positive for tumor; small portion of salivary gland had no tumor. Metastatic SCCa in 5 of 34 lymph nodes of neck dissection; no tumor in parotid lymph nodes. Pathology report says this could be a parotid carcinoma because the bulk of the disease is in the parotid, but it could also be metastatic...correlate with clinical findings. Doctor calls this unknown primary of the head and neck. Is this C80.9 or C76.0?

For cases diagnosed 1998-2003: The data item "Surgery of Primary Site" is intended to record only surgeries of the primary site. If the primary site is unknown or ill-defined, it is impossible to determine whether or not a particular surgery was performed on the primary site. "Surgical Procedure of Other Site" collects much less specific information; however, this is the correct data item to record surgery performed when the primary site is unknown or ill-defined.

For the case example, code the primary site as C76.0 [Head, face or neck, NOS]. Code Surgery of Primary Site as 98 [All unknown and ill-defined disease sites, with or without surgical treatment]. Code Surgical Procedure of Other Site as 1 [Non-primary surgical procedure performed].

20031180 Histology (Pre-2007)--Breast: What code is used to represent the histology "ductal adenocarcinoma with medullary features?"

For tumors diagnosed prior to 2007:

Medullary is a subtype of duct and "with features of" is a term that indicates a majority of tumor. If this is an invasive adenocarcinoma with no in situ component, code to 8510/3 [Medullary adenocarcinoma]. If only one of the components is invasive, code that component.

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.

20031156 Histology (Pre-2007)--Ovary: Should the histology "endometroid adenocarcinoma arising in a serous fibroadenoma" be coded to 8380 [Endometroid adenocarcinoma, NOS] or 9014 [Malignant serous fibroadenoma]?

For tumors diagnosed prior to 2007:

The best code is 8381/3 [Endometroid adenofibroma, malignant]. According to our pathologist consultant: "Serous 'fibroadenoma' is not exactly standard terminology. I would guess the pathologist is looking at an adenofibroma with more fibro and less adeno and thus has changed the terminology around. The combination of the benign serous and malignant edometrioid is also a bit unusual. Each of the proposed codes is defendable, but I prefer endometrioid adenofibroma, 8381/3, because it puts the tumor in the adenofibroma category (less common) yet still identifies the malignant element (endometrioid), even though it does lose the serous. But anyone wanting to look at malignant adenofibromas would find the case, and we would carry it under the appropriate malignant component."

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.

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.

Reportability/Histology--Hematopoietic, NOS: What histology code is used for a patient diagnosed with "myelodysplasia" prior to 2001, if a bone marrow biopsy in 2002 is consistent with myelodysplastic syndrome with refractory anemia with bilineage dysplasia with excess blasts and the final impression is "myelodysplastic syndrome slowly evolving toward acute leukemia?"

Patient was admitted in July 15, 2002. Per the H&P, patient was diagnosed 5 years ago with myelodysplasia. Patient had bone marrow biopsy about 5 years ago and then again on 6-10-02. Patient has become transfusion dependent since mid-March. Bone marrow on 6-10-02 was consistent with myelodysplastic syndrome with refractory anemia with bilineage dysplasia with excessive blasts. Impression: Myelodysplastic syndrome slowly evolving toward acute leukemia. Plan: start chemo. 7-16-02 bone marrow biopsy showed acute myeloid leukemia.

Can we assume that the myelodysplasia diagnosed 5 years ago was refractory anemia and therefore, patient's first reportable diagnosis would be the AML? Or is the 6-10-02 bone marrow biopsy showing refractory anemia to be the first reportable diagnosis because the term "myelodysplasia" is non-specific?

For cases diagnosed prior to 1/1/2010:

Based on the information provided, the diagnosis date is June 2002. The diagnosis is 9895/3, acute myeloid leukemia with multilineage dysplasia (AML with prior myelodysplastic syndrome). According to the SEER table of hematopoietic diseases, refractory anemia and myelodysplastic syndrome followed by AML is one primary.

Prior to 2001, a diagnosis of myelodysplasia was not reportable.

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.

20031153 Laterality/Multiple Primaries (Pre-2007)--Ovary: Are ovarian primaries with bilateral involvement always coded to laterality 4 (bilateral)? See Description. Example: "Right ovary with mass replacing majority of ovarian tissue consistent with serous adenoca. Lt ovary with foci of adenoca." No specific statement of primary. Can we assume that the malignancy originated in the right ovary since it is more extensively involved or should laterality be coded 4 because both ovaries have tumor?

For tumors diagnosed prior to 2007:

If one ovary is listed as the primary site, code laterality to that ovary. The example above is one of those times when you would code to the single ovary. The issue of one or both ovaries being involved is handled in staging.

Abstract the example above as a single primary with code 1 [Right] for laterality.

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.

20031200 Reportability/Terminology, NOS--Hematopoietic, NOS: Is "smoldering" multiple myeloma reportable to SEER?

For cases diagnosed prior to 1/1/2010:Yes, "smoldering" multiple myeloma is reportable to SEER as multiple myeloma [9732/3].

According to our pathologist consultant, "smoldering" multiple myeloma would certainly refer to a diagnosed process. Smoldering means the process is progressing, but perhaps slowly, or even at a slower pace than might be expected.

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.
