Primary Site/Histology (Pre-2007)/EOD Fields/Surgery of Primary Site--Abdomen, NOS: What codes are used to represent these fields for a case with a resection of the rectosigmoid and adjacent tumor mass that demonstrated no tumor in the rectosigmoid but extramural to the colon there was an endometrioid adenocarcinoma arising in association with an area of endometriosis (possibly within the pericolic soft tissue or in an ovarian remnant)?
First Course Treatment--All Sites: The patient has undergone part of the planned first course of treatment when a metastatic deposit is identified. If the patient continues with the planned first course of treatment, should the modalities of treatment given after the metastatic deposit is discovered be included in the coding of the first course of cancer-directed treatment fields?
Yes, those modalities should be counted as part of first course of cancer-directed treatment if the patient continues with the planned first course. For example, if patient has the originally planned type of surgery, radiation, or drug protocol, then code the given treatment as first course.
Caution: It is not a change in the treatment plan if the drugs are changed but the action of the drugs remains the same. This is still first course. However, if the treatment is changed from a chemotherapy drug to a hormonal drug following the discovery of the mets, do not code the hormonal therapy as first course.
Reportability/Terminology, NOS--Hematopoietic, NOS: Are the diagnoses "myelodysplastic syndrome," "myelodysplastic syndrome, thrombocytopenia" and "myelodysplastic syndrome, anemia" all reportable to SEER for diagnosis 2001 and later?
For cases diagnosed prior to 1/1/2010:"Myelodysplastic syndrome" (NOS) is reportable to SEER--ICD-O-3 code 9989/3. "Myelodysplastic syndrome, thrombocytopenia" is not reportable to SEER because "thrombocytopenia" is not reportable. "Myelodysplastic syndrome, anemia" is not reportable to SEER because "anemia" is 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.
Primary site: What primary site do I assign to a Squamous Cell Carcinoma of the parapharyngeal space when there is no other info available regarding a more definitive site within the parapharyngeal space? Each physician involved with the case states the primary site is the parapharyngeal space. This is a patient who was diagosed and treated elswhere and was seen at our hospital several months later for a radical neck dissection for suspected lymph node mets.
Assign C139 for a primary originating in the parapharyngeal space. This space contains part of the parotid gland, adipose tissue, lymph nodes, nerves, arteries and veins.
Multiple Primaries (Pre-2007)/Primary site/EOD-Extension--Head & Neck: How many primaries are represented by an invasive squamous cell carcinoma of the floor of mouth with in situ squamous cell carcinoma involvement of the frenulum?
For tumors diagnosed prior to 2007:
Code the Primary Site field to C04.9 [floor of mouth]. Because the cancer did not INVADE into a neighboring site (through wall, through soft tissue), it just spread along the mucosa (in situ) to involve the frenulum, this is one primary.
For cases diagnosed 1998-2003, in situ extension via mucosal spread to the frenulum is ignored for purposes of coding EOD-Extension.
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.
MP/H Rules/Histology--Prostate: What is the histology code for a prostate case whose histology reads “adenoca with mixed ductal and acinar variants?
Assign 8523/3.
The 2013 revision to ICD-O-3 has a new code for mixed acinar ductal carcinoma; however, this new code will not be implemented in the U.S. until 2018 or later. Page 7 of the Guidelines for ICD-O-3 Update Implementation document released by NAACCR 1/1/2014 instructs us to use 8523/3 in the meantime.
Histology (Pre-2007)--Breast: How is "invasive lobular carcinoma with signet ring cell features (95%) and ductal features (5%)" coded for a single tumor diagnosed prior to 2007?
For cases diagnosed 1/1/04-12/31/06, code histology to 8524 [Lobular mixed with other types of carcinoma]. Assuming there is no mention of in situ, Histology Coding Rule 3 applies: Use a mixed histology code if one exists
For cases diagnosed 2007-2014, 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--Hematopoietic, NOS: The Abstracting and Coding Guide for the Hematopoietic Diseases, page 47, states to determine whether the physician is using the term myelodysplasia to describe bone marrow marrow malfunction or a neoplasic syndrome in order to determine reportability. What do we do when there is no information one way or the other?
For cases diagnosed prior to 1/1/2010:Without further information, the term "myelodysplasia" alone is not reportable. If a more definitive diagnosis is made later, the case may become reportable.
For cases diagnosed 1/1/10 and later, 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/Behavior--Ovary: Is ovarian mucinous
borderline tumor with foci of multifocal intraepithelial carcinoma reportable?
Report ovarian mucinous borderline tumor with foci of
multifocal intraepithelial carcinoma. The foci of intraepithelial carcinoma
makes this reportable. See the list of synonyms for in situ in the SEER Manual,
Behavior Code data item.
