First Course Treatment/Surgery of Primary Site--Breast: How is "Goldilocks," also referred to as oncoplastic reconstruction, in the surgery section for breast cancer patients coded?
Code Goldilocks mastectomy in Surgery of Primary Site. Breast surgery code 30 seems to be the best available choice for "Goldilocks" mastectomy. It is essentially a skin-sparing mastectomy with breast reconstruction. The choice between code 30 and codes in the 40-49 range depends on the extent of the breast removal. Review the operative report carefully and assign the code the best reflects the extent of the breast removal.
Reportability--Brain and CNS: Is Langerhans cell histiocytosis [9751/1] of the meninges [C709] reportable?
For cases diagnosed prior to 1/1/2010:Yes. The criteria for reportable benign/borderline CNS tumors is based on location (site) and behavior (benign/borderline). There is no caveat for histologic type. Therefore, this would be reportable as these tumors have been reported arising from the meninges or choroid plexus.
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)--Melanoma: How is histology coded for a final pathology diagnosis of "malignant melanoma, NOS" that is clinically described as a nevus?
For tumors diagnosed prior to 2007:
Code 8720 [malignant melanoma]. Assign the histology code based on the histology stated in the final diagnosis on the pathology report. The pathology report must say melanoma arising in junctional nevus to use the code 8740/3 [Malignant melanoma in junctional nevus].
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.
Grade, Differentiation--All Sites: If the grade given for the primary site is from a provisional diagnosis and the grade given for a metastatic site is from a final diagnosis, should we follow the SEER rule that says to code the grade as stated in the final diagnosis (e.g., Provisional diagnosis: High grade papillary serous carcinoma of ovary. Final dx: poorly differentiated adenocarcinoma in a caval lymph node)?
Code the Grade, Differentiation field to 4 [High grade] from the examination of the ovary (primary site). Do not code grade from a metastatic site.
EOD-Extension/EOD-Lymph Nodes--Bladder: Are "perivesical nodules" coded in the EOD-Lymph Nodes field or are they discontinuous extension and coded in the EOD-Extension field?
For cases diagnosed 1998-2003:
Code "perivesical nodules" in the EOD-Lymph Nodes field as involvement of regional lymph nodes. Each gross nodule of metastatic carcinoma in the fat surrounding an organ is counted as one positive regional lymph node.
EOD-Extension--Pancreas: How do you code extension when a mass is described on exploratory laparotomy as compressing the duodenum, arising in the head of the pancreas, "extending around" the superior mesenteric vein and artery, and "encasing" the portahepatis?
For cases diagnosed 1998-2003:
Code the EOD-Extension field to 40 [extension to peripancreatic tissue, NOS]. Neither of the terms "extending around" nor "encasing" are interpreted as involvement with tumor by SEER.
MP/H Rules/Histology--Kidney, renal pelvis: How would you code this histology: Renal cell carcinoma, clear and eosinophilic cell type?
Kidney rule H5 applies, code the more specific histology which is clear cell renal cell carcinoma (8310/3). Per the WHO Tumors of the Urinary System, clear cell renal cell carcinoma contains both clear and eosinophilic cytoplasm. Eosinophilic is not a type or variant of renal cell carcinoma.
Multiple primaries--Heme & Lymphoid Neoplasms: Is this 2 primaries? In 2011, a patient had a spinal mass biopsied positive for DLBCL and follicular lymphoma. The heme rules make this one primary coded as DLBCL. Patient had 2 rounds of chemo, but in 2014, he had a recurrent tumor in the same location. The 2014 biopsy was follicular lymphoma. Is this a new primary -- conversion of acute to chronic after treatment? Or is it the same, since FL was diagnosed in the original specimen?
Rule M13 applies, abstract as two primaries. Since both DLBCL and FL were present in 2011, rule M2 does not fit -- not a single histology. Rule M13 reflects the situation in this case much better: an acute neoplasm which was treated and a chronic neoplasm diagnosed later.
Reportability--Brain and CNS: Are hemangioma, NOS (9120/0), cavernous hemangioma (9121/0) or venous hemangioma (9122/0) reportable when they arise in the brain or CNS?
Hemangioma, NOS (9120/0) and cavernous hemangioma (9121/0) arising in the dura and parenchyma of the brain/CNS are reportable.
Venous angiomas (9122/0) are not reportable wherever they arise. The primary site for venous hemangioma arising in the brain is blood vessel (C490). The combination of 9122/0 and C490 is not reportable. This is a venous abnormality. Previously called venous angiomas, these are currently referred to as a developmental venous anomalies (DVA).
