First course of treatment/Radiation therapy--Kidney: Patient has a CT-guided biopsy of a right renal mass with procedure details under the Interventional Radiology Procedure Note stating "Gelfoam tract embolization." Is this particular embolization treatment?
Gelfoam tract embolization for a CT-guided renal biopsy is not treatment. It is a method to plug the biopsy track to reduce the risk of hemorrhage.
Primary site: Is there a physician priority list for coding primary site? For example, the surgeon states during a pancreatectomy that the primary is in body while the pathologist states in their synopitc report that primary is neck; neither is in agreement, or neither is available for confirmation.
As a general rule, the surgeon is usually in a better position to determine the site of origin compared to the pathologist. The surgeon sees the tumor in its anatomic location, while the pathologist is often using information given to him/her by the surgeon and looking at a specimen removed from the anatomic landmarks. However, when a pathologist is looking at an entire organ, such as the pancreas, he/she may be able to pinpoint the site of origin within that organ.
In the case of pancreas body vs. neck, the neck is a thin section of the pancreas located between the head and the body. It may be a matter of opinion whether a tumor is located in the "body" vs. the "neck." In the situation you describe, we would give preference to the surgeon and assign the code for body of pancreas, C251.
Histology (Pre-2007): What code is used to represent the histology "PD infiltrating duct ca with focal sarcomatoid pleomorphic features?"
For tumors diagnosed prior to 2007:
Code histology as 8500/33 [Infiltrating duct carcinoma, poorly differentiated]. "Features" is a term from the list indicating a majority of the tumor, however; in this case "features" is modified by "focal" which does not indicate a majority of the tumor.
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 tubular adenoma reportable if the final diagnosis is "high grade atypia" and the diagnosis comment is "atypia limited to muscularis mucosa areas of pseudostratification [formerly qualifying for carcinoma in situ]"?
This case is not reportable.
The pathologist would need to include "carcinoma in situ" as part of the final diagnosis in order for this case to be reportable.
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.
Histology (Pre-2007)/Flag--Pancreas: How is histology coded given that 8046 [non-small cell carcinoma] of the pancreas is not on the SEER Site/Type validation listing?
For tumors diagnosed prior to 2007:
Assign 8046 [non-small cell carcinoma] for "non-small cell carcinoma" of the pancreas. If necessary, override any site/type edits.
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 (Pre-2007)--Pancreas: Is a "composite mucinous adenocarcinoma and squamous cell carcinoma" coded to 8560 [adenosquamous carcinoma] or should 8480 [mucinous adenocarcinoma] be coded rather than 8070 [squamous carcinoma] because mucinous adenocarcinoma is a higher histology code than squamous carcinoma?
For tumors diagnosed prior to 2007:
Assign code 8560 [adenosquamous carcinoma]. According to our pathologist consultant, the mix of adenocarcinoma and squamous carcinoma is adenosquamous carcinoma. Adenosquamous tumors are rare, but known, representing 3-4% of pancreatic carcinomas.
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.
CS Extension--Prostate: Does the term "activity" in a Prostascint report indicate a clinically apparent tumor, tumor extension or tumor involvement for this primary site? (http://www.rtrurology.com/prostascint.htm)
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.
No, the term "activity" alone does not indicate clinically apparent tumor or involvement.
MP/H Rules/Histology--Breast: Which report and diagnosis should be used to code the histology if an excisional biopsy that removes the majority of the tumor has a diagnosis of "carcinoma," and the subsequent lumpectomy diagnosis is "microscopic residual disease consistent with infiltrating duct carcinoma"?
For cases diagnosed 2007 or later, code histology for this case to 8010 [carcinoma]. The histology is coded from the pathology report with the most representative specimen (the most tumor tissue) even when the most representative specimen has a less specific histology.
