Update to Current Manual/Race: How is Race coded when stated as Hispanic and there is no other information? See Discussion.
There appears to be discrepant information in the 2024 (and prior) SEER manual regarding race coding when the patient is described only as Hispanic/Latina. Page 78 tells us to Code as 01 (White) when: b. There is a statement that the patient is Hispanic or Latino(a) and no further information is available
A person of Spanish origin may be any race; however, for coding race when there is no further information other than “Hispanic” or “Latino(a),” assign race as White as a last resort instead of coding unknown.
However, in Appendix D, under "Other Race descriptions", there is a statement that "If no further information is available, code as 99 Unknown." The list includes "Hispanic."
Assign code 01 (White) for Hispanic when there is no additional information. It is listed in the 2024 SEER Manual, Race Coding Instruction 6.b.i. and in Appendix D for code 01. We will remove Hispanic from the list in Appendix D under code 99 in the next version of the manual.
EOD 2018/EOD Primary Tumor/Tumor Size--Clinical--Prostate: How is Tumor Size--Clinical coded when there is an incidental finding of prostate cancer on prostatectomy for another reason? See Discussion.
SEER*RSA states EOD Primary Tumor should be coded to 800 for an incidental finding of prostate cancer on prostatectomy for other reasons.
The SEER Manual states to assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded to 800; however, the definition for Tumor Size--Clinical indicates clinical classification is composed only of diagnostic workup prior to treatment.
If there is no clinical workup for an incidental finding of prostate cancer, code 000 does not seem appropriate (does not meet criteria for clinical classification). Code 999 seems more appropriate for incidental findings during surgery for other reasons. The SEER Manual does not provide this exception in the current instruction.
Assign code 000 for Tumor Size--Clinical when EOD Primary Tumor is coded 800 (No evidence of primary tumor). Code 000 indicates no tumor was found since there was no clinical workup to identify this incidentally found cancer. This is a special instruction for cases coded 800 in EOD Primary Tumor. Text fields can be used to record details.
First Course Treatment/Neoadjuvant Therapy--Melanoma: How are the three Neoadjuvant Therapy data items (Neoadjuvant Therapy, Neoadjuvant Therapy--Clinical Response, Neoadjuvant Therapy--Treatment Effect) coded when a patient is diagnosed with melanoma in the lymph nodes with no primary skin site identified? The physician gives immunotherapy as neoadjuvant therapy with planned and carried out surgical resection of involved lymph nodes following completion of immunotherapy. There is no "planned definitive surgical resection of the primary site" as no primary site was found,
Assign code 0 to each of the three Neoadjuvant Therapy data items in this situation.
We will add an example to the coding instructions for these data items in the next release of the manual.
Primary site--Breast: Patient was diagnosed with invasive ductal carcinoma of the left breast. Site of mass is 2:00 to 3:00. What is the correct site code, C504 upper outer quadrant (UOQ) or C50.8 (overlapping)?
Primary site--Heme & Lymphoid Neoplasms: Does Rule PH27 apply meaning that primary site is coded to C809 or would it be more appropriate to code to C269 GI Tract NOS since all disease involves the GI tract and this is more specific?
Extranodal lymphoma first diagnosed in the stomach (fundus and antrum) which upon further investigation also involved the small bowel (MALT Lymphoma) in the absence of lymph node findings. MD staged this IIE. Initial thought was Gastric, but PET/CT indicated abnormal uptake involving loop of distended small bowel in the pelvis.
Assign C269 for Gastrointestinal tract, NOS. Apply Rule PH24, code to the organ when only an organ is involved. This rule can be used for NOS sites such as GI tract, NOS.
Based on the information provided, this lymphoma is confined to the GI tract -- stomach and small bowel.
Primary site/Biliary tract--Ampulla of Vater: What is the correct primary site code for intra-ampullary and periampullary adenocarcinoma, C241 (8144/3) or C249? See Discussion.
Ampulla, biopsy: High grade dysplasia with focal intramucosal carcinoma in a background of ulceration with acute and chronic inflammation.
Surgery pathology: Head of pancreas, duodenum, and distal stomach, pancreaticoduodenectomy-Ampulla, Adenocarcinoma, intestinal type, intra-ampullary and peri-ampullary (mixed type). Grade moderately differentiated, 1.5cm. Tumor invades into duodenal submucosa. Lymphovascular Invasion: Foci suspicious for lymphovascular invasion identified. Perineural Invasion: Present.
Synoptic report: Tumor Site Intra-ampullary and peri-ampullary (mixed type). Histologic Type Adenocarcinoma, intestinal type.
There is not enough information regarding site in radiology reports or operative report. CT-A/P/C:The patient's known ampullary mass is not well visualized on this exam. No significant intrahepatic or extrahepatic biliary ductal dilation is identified. The pancreatic duct is normal caliber.
Assign C241. Ampulla (C241) includes both periampullary and intra-ampullary.
Primary Site/Histology--Intrahepatic Duct: How are primary site and histology coded for cholangiocarcinoma cases when the pathology only shows a liver tumor and other involvement. See Discussion.
A common scenario is a patient has a positive CT of the abdomen/pelvis for liver mass only. Biopsy of the liver mass is positive for cholangiocarcinoma. The physician is also calling the liver tumor the primary site with histology of cholangiocarcinoma. There is no evidence of intrahepatic bile duct (C221) or gallbladder (C240) involvement which are sites specific to this histology. The hematology/oncology consult stages this as Stage IIIA, T3N0M0 intrahepatic cholangiocarcinoma. Can we code cholangiocarcinoma with site code C220 (liver) or should we assume that C221 (intrahepatic bile ducts) would be a better code to reflect this histology?
Assign C221 (intrahepatic bile duct) as the primary site for cholangiocarcinoma (8160/3). Our expert GI pathologist confirms that even when intrahepatic bile ducts are not specifically mentioned, intrahepatic cholangiocarcinoma originates in the intrahepatic bile ducts.
Primary site--Anus/Anal Canal: What site do you code squamous cell carcinoma of the anal verge?
Assign C211 for anal verge. Anal verge is defined as the lower (distal) end of the anal canal, junction between the skin of the anal canal and the perianal skin, http://www.seer.cancer.gov/manuals/2015/AppendixC/rectosigmoid/coding_guidelines.pdf
