Multiple Primaries (Pre-2007): How many primaries? See Discussion.
5/05 perianal skin bx, 6/05 mapping bx perianal skin, 9/05 punch bx perianal skin: all positive for extramammary Paget Disease. 9/05 Perianal Excision of Paget w/V-Y flap repair. Path: Perianal and anal skin: Extramammary Paget disease associated with: Invasive adenoca of anal canal. Anal margins positive for invasive adenoca. Comment: invasive adenoca with local mucinous features involving the anal margin/end of specimen. This adenoca is in continuity with (associated with) extensively diffuse extramammary Paget disease. Unclear whether the adenoca represents a rectal primary with spread to perianal area, anal gland adenoca or mets. 12/05 AP resection-no residual Paget or invasive neoplasm.
For tumors diagnosed prior to 2007:
There is one primary.
Code the histology to 8542 [Paget disease, extramammary]. Code the primary site C210 [anus]. Histology rule 7 on page 87 of the 2004 SPCM applies in this case.
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: How is an "advanced MDS (RAEB-T)/emerging AML" coded when discovered on a bone marrow biopsy?
For cases diagnosed prior to 1/1/2010:Code histology to 9984/3 [RAEB-T]. This particular MDS is refractory anemia with excess blasts in transformation. It has not yet progressed to acute myeloid leukemia.
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.
CS Site Specific Factor--Head & Neck: If a lymph node dissection of the neck reveals that 1/24 lymph nodes is positive and the positive 5.6 cm lymph node extends throughout levels II-IV, how are the SSF 3 (status of levels I-III lymph nodes) and SSF4 (status of levels IV-V lymph nodes) fields coded?
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.According to the CS Steering Committee, code 999 for SSF 3 and SSF 4. In this case, do not make assumptions about which level of lymph nodes were involved.
Laterality--Breast: Should laterality be coded to 9 [Paired site but no information concerning laterality] or to the side with the positive lymph nodes for a case in which no breast mass is found but positive axillary lymph nodes are found on only one side?
Code laterality of the primary site to the side with the positive nodes when there are unilateral positive nodes and the laterality of the primary site is otherwise unknown.
Reportability--Hematopoietic, NOS: Is a "refractory cytopenia with excess blasts" discovered on a bone marrow biopsy reportable?
For cases diagnosed prior to 1/1/2010:
Refractory cytopenia with excess blasts (RCEB) is reportable. RCEB is the same disease process as refractory anemia with excess blasts, except there is more than one type of blood cell that is low (red, white, platelets).
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--Colon: Is a pathologically confirmed "tubulovillous adenoma with high grade dysplasia" reportable if clinical diagnosis at the time of the subsequent re-biopsy states "follow-up for colon polyps with ca in situ"? See Discussion.
SINQ 20000245 states that high grade dysplasia is not synonymous with behavior code 2 (in situ). However, the 2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case."
A pathologic diagnosis has priority over a clinical diagnosis. According to the pathologist, this case is not reportable. A re-biopsy is not treatment.
Histology (Pre-2007)--Melanoma: How is a "plaque-like nodular spitzoid malignant melanoma" coded?
For tumors diagnosed prior to 2007:
Code histology to 8721 [nodular melanoma]. Essentially, "plaque-like nodular spitzoid malignant melanoma" is nodular melanoma. Code 8721 is the most specific ICD-O-3 histology code available for this diagnosis.
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.
Reportability: Is a tumor reported as "neoplasm" or "neoplasia" per the pathology report, which is subsequently clinically referred to as "carcinoma" reportable? See Discussion.
Example 1: Lung-Wedge resection and subsequent left lower lobe lobectomy showed papillary epithelial neoplasia. Tumor board and subsequent reports state "nonsmall cell carcinoma of lung."
Example 2: Kidney-Partial nephrectomy showed epithelial neoplasm, clear cells with low grade cytology. Subsequent urology clinic notes state that path revealed clear cell renal carcinoma.
2004 SEER manual states that "cases clinically diagnosed are reportable. If the physician treats a patient for cancer in spite of the negative biopsy, accession the case." Do we also accession the case if primary site has been resected? Would diagnostic confirmation be coded 8 (clinical diagnosis only)?
Accession the case and code Diagnostic Confirmation as 8 [clinical diagnosis only]. Accession a case with negative pathology when the clinician is aware of the negative pathology and continues to refer to the case as malignant.
CS Lymph Nodes--Lung: Do modifying terms such as "borderline" affect whether lymph nodes are coded as involved when they are used in conjunction with the descriptors listed in Note 2 (i.e., mass, adenopathy or enlargement) for lung primaries? See Discussion.
Lung primary: CT states "borderline" enlarged hilar lymph nodes. Note 2 in the Lung schema under CS Lymph Nodes does not address qualifiers.
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.
Do not code the hilar lymph nodes as involved in this case. "Borderline" enlarged hilar lymph nodes do not meet the clinical criteria for enlargement.
CS Extension--Head & Neck: If a 2 cm left tonsil primary extends to the lateral aspect of the soft palate, should extension be coded to 40 [Soft palate, inferior surface including uvula or soft palate NOS] or 42 [Soft palate, superior (nasopharyngeal) surface] for a tonsil 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.
Extension code 40 is for extension from the tonsil to the back (lower) part of the soft palate, or soft palate, NOS. Code 42 is for extension to the front (higher, nasopharyngeal surface) part of the soft palate.
Inferior soft palate is the back (lower) part of the soft palate (C051). Superior soft palate is the front, (nasopharyngeal surface) of the soft palate (C113).
