The previous SEER Program Coding and Staging Manual included Appendix C that has Coding Guidelines for some sites. The breast guidelines specifically instructed one to code the subsite with the invasive tumor when the pathology report identifies invasive tumor in one subsite and in situ tumor in a different subsite or subsites. The current Breast Solid Tumor Rules Table 1: Primary Site Codes refers one back to the SEER Manual and COC Manual for a source document priority list but does not make mention of invasive vs. in situ on that final version of the source document.

In addition, the Colon Solid Tumor Rules currently contains no Site Coding Section/Table. However, the Lung Solid Tumor Rules do and also refer one to the SEER/COC Manuals for document priority lists. The Urinary Solid Tumor Rules has both the Primary Site Codes Table and an additional section called Priority for Coding Primary Site, which does not reference a document priority list or other manuals. Unfortunately, there is additional information in Appendix C Bladder Coding Guidelines that may have been used in the past regarding site source priority.

Could the remaining applicable Appendix C information be consolidated into the Solid Tumor Rules consistently among all the sites to lessen the need for additional manual referencing? Also, is there a reason one site includes the Priority Site Coding instructions and others do not?

Will histology code 8050 [papillary carcinoma, NOS] be used for cases diagnosed 2007 and later? The MP/H Rule H4 for urinary primaries states to code papillary carcinoma to code 8130, but Rule M6 includes tumors coded to 8050.

The IARC publication Pathology and Genetics of Tumours of the Urinary System and Male Genital Organs uses code 8130 only for papillary carcinoma.

The final diagnosis on the pathology report, "Omentum: mixed epithelial borderline tumor with multiple foci of intraepithelial carcinoma. Peritoneal fluid for cytology: neoplastic cells present; low grade serous neoplasm. Lymph nodes, right pelvic: one lymph node harboring implants of serous borderline tumor and endosalpingiosis within the subcapsular sinus. Bilateral fallopian tubes and ovaries: mixed epithelial borderline tumor with multiple foci of intraepithelial carcinoma involving ovarian surface and serosal surface of the tube. Detached fragment of borderline tumor within the tubal lumen. Uterus, cervix, and segment of colon: mixed epithelial borderline tumor with multiple foci of intraepithelial carcinoma involving parametrial and paracervical tissue, cul de sac, uterine and colonic serosa. Nine pericolonic lymph nodes negative for tumor. Stage III.

I&R # 45622 asked if a mucinous borderline tumor with intraepithelial carcinoma and focal microinvasion is reportable. The answer given on that site was that the case is not reportable. According to MPH, FORDS, and Collaborative Stage, intraepithelial carcinoma is in situ, behavior code 2, and is reportable. Has this changed?

According to this article, PRRT treatment lutetium Lu 177 dotatate was approved earlier this year by the United States Food and Drug Administration for adult use. PRRT is a nuclear medicine therapy that travels throughout the body looking for a certain receptor within neuroendocrine tumors. These include pancreatic and small neuroendocrine tumors in the gastrointestinal tract. Once absorbed into the tumor, the radioactive material starts to break down tumor cells, killing them. It is the first radioactive drug approved for the targeted treatment of gastroenteropancreatic neuroendocrine tumors.

We previously downloaded the 8/22/2018 ICD-O-3 histology update tables which included the note, not reportable for 2018, for both of these terms (with an updated histology 8071/2). SINQ 20180020 confirms differentiated penile and vulvar intraepithelial neoplasia are NOT reportable for 2018 (as does 20160069). However, when looking at the 8/22/2018 ICD-O-3 histology update table today, the not reportable for 2018 comment has been removed and it appears these two terms are reportable. Which is correct?

The patient underwent a PTA biopsy of a lytic mass showing metastatic adenocarcinoma. Imaging revealed a large hepatic mass consistent with cholangiocarcinoma. The physician's impression on a physical exam note was the PTA biopsy was most consistent with intrahepatic cholangiocarcinoma. However, the PTA pathology report was reviewed at this facility and the final diagnosis was not stated to be cholangiocarcinoma, only adenocarcinoma, NOS.

The priority order for coding histology rules in the MP/H Manual indicates pathology has priority over documentation in the medical record. Following the rules in the MP/H Manual, the histology would be coded as 8140 [Adenocarcinoma, NOS]. While this may be technically correct, it seems that intrahepatic cholangiocarcinoma is often diagnosed as adenocarcinoma on biopsy, but further stated to be cholangiocarcinoma by the physician once other primary sites have been excluded. By applying the rules in the MP/H Manual, cases that seem better characterized as cholangiocarcinomas are being collected as adenocarcinoma, NOS. Should the histology be adenocarcinoma [8140/3] or cholangiocarcinoma [8160/3] for these cases?

Washington State added to birth certificates, which allows people to have their certificates changed to this non-binary gender designation. Gender X is defined as a gender that is not exclusively male or female, including, but not limited to: intersex, agender, amalgagender, androgynous, bigender, demigender, female-to-male, genderfluid, genderqueer, male-to-female, neutrois, nonbinary, pangender, third sex, transgender, transsexual, Two Spirit, and unspecified.
