Multiple primaries (Pre-2007)/EOD-Extension--Fallopian Tube: How many primaries are coded when endometrioid adenocarcinoma involves bilateral fallopian tubes? See Discussion.
The pathologist states "because of the intimate association with the luminal line of the fallopian tube it is felt that this represents synchronous primaries rather than mets." The SEER Code Manual only lists ovary, retinoblastomas, and Wilms Tumors under the bilateral code stated to be a single primary.
For tumors diagnosed prior to 2007:
Complete two abstracts, one for left fallopian tube and one for right fallopian tube. This case has been determined to be two primaries by the pathologist. Bilateral involvement of paired sites (other than ovary, retinoblastoma and Wilms tumor) with the same histology within two months requires a determination of whether there are one or two primaries. The pathologist in the case above has made this determination.
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--Head of Pancreas: What code is used to represent extension to the superior mesenteric artery? See Discussion.
In the CS coding scheme for Head of Pancreas, superior mesenteric artery is listed under both code 54 (T3) and 60 (T4).
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.
Assign code 60 for a primary in the head of the pancreas extending to the superior mesenteric artery. CS Extension code 54 should be Superior mesenteric VEIN and code 60 should be Superior mesenteric ARTERY. An errata will be issued by CS. In addition, extension 54 indicates resectable disease and code 60 is not resectable.
Primary Site/Sarcoma--Breast: Is the primary site coded to C504 [upper-outer quadrant of breast] or C493 [ Connective, subcutaneous and other soft tissue of thorax ] for a tumor described as a "high grade soft tissue sarcoma present in the upper outer quadrant of breast"?
If the sarcoma is primary in the breast, code the primary site to C504 [upper-outer quadrant of breast]. C500 - C509 includes soft tissue of breast.
CS Tumor Size--Breast: When the diagnosis is inflammatory carcinoma of the breast, must the CS tumor size always be 998? See Discussion.
I have no specific example of a situation; I am writing an edit check and wondering if there would be any exceptions to this rule.
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. For inflammatory carcinoma, code the size of the tumor in CS tumor size. Use code 998 [diffuse] when the tumor is stated to be "diffuse."
Page 27 in Part I of the CS manual will be corrected to define code 998 for breast as only "diffuse." The errata should be distributed in July 2004.
Histology (Pre-2007)--Lung: Should "moderately differentiated adenocarcinoma of scar type, intermixed with bronchiolo-alveolar carcinoma" be coded to 8250 [bronchiolo-alveolar adenocarcinoma, NOS] or 8255 [adenocarcinoma of mixed subtypes]?
For tumors diagnosed prior to 2007:
Code Histology to 8255 [Adenocarcinoma with mixed subtypes]. This is a single tumor containing both a scar carcinoma and a bronchiolo-alveolar carcinoma--use 8255. The synonym for 8255 is adenocarcinoma combined with other types of carcinoma (not just subtypes).
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 Tumor Size: Can we take the size of a "polypoid" mass? See Discussion.
3/04 Colonoscopy: 4 cm semi-circumferential friable mass in sigmoid colon. Path: Tubulovillous adenoma indeterminate for malignancy. 4/04 Sigmoid Colectomy: 5 x 4 polypoid mass: WD Adenocarcinoma arising in a tubulovillous adenoma.
Define "Polypoid". Size of "polypoid" mass. Would the size be coded to 050 or 999?
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.If the pathology report confirms that the entire polyp is malignant, code the size of the polyp/polypoid mass. If the pathology report does not confirm that the entire polyp is malignant, code 999.
Code tumor size as 999 [Unknown] for the example above. Do not code the size of the polypoid mass in this example. The size given above is the size of the polypoid mass, not the size of the malignancy.
Histology (Pre-2007)--Colon: Must a case be specifically labeled "familial adenomatous polyposis" or is the mere presence of numerous/multiple polyps sufficient for coding the histology to FAP?
For tumors diagnosed prior to 2007:
The presence of numerous/multiple polyps is not necessarily adenomatous polyposis coli. Adenomatous polyposis is an extreme condition usually characterized by the presence of hundreds of polyps and should be identified as such either clinically or pathologically.
Look for the term "Familial adenomatous polyposis," FAP or one of its synonyms:
Adenomatosis of the colon and rectum [ACR]
Familial adenomatous colon polyposis
Familial colonic polyposis
Multiple familial polyposis
In the absence of these terms, the following probably indicate a diagnosis of FAP:
Hundreds of adenomatous polyps throughout large intestines, and at times, throughout the digestive system
Development of polyps as early as ten years of age, but more commonly at puberty
History of colectomy
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.
Date of Diagnosis: When a 4/04 clinical impression indicates the appearance of a carcinoma that is contradicted by a negative 4/04 biopsy but is confirmed by a 5/04 resection, should the diagnosis date be coded to April or May? See Discussion.
4/04 colonscopy: irregular fungating mass that has appearance of carcinoma. 4/04 Bx: high grade dysplasia. 5/04: LAR. 5/04 Path: 3.2 X 2.5 cm mass wd adenoca with invasion of muscularis propria.
Should the diagnosis date be 4/04 based on the clinical impression during the colonoscopy OR 5/04 since the path for the bx was negative?
The date of diagnosis for the example above is 05/04 -- the date of the pathology report confirming malignacy. The biopsy in 04/04 negated the 04/04 clinical statement.
Primary Site--Head & Neck: How is this field coded for a tongue primary described as "located on the lateral" or "left oral" tongue? See Discussion.
Case 1. Patient with squamous cell carcinoma, left oral tongue.
Case 2. Squamous cell carcinoma, left lateral tongue.
Case 3. Patient status post biopsy of lesion on tongue. Exam: healing left lateral tongue incision with sutures in place in underside of tongue.
Code Primary Site for cases 1 and 2 above to C023 [Anterior 2/3 of tongue, NOS]. Code lateral tongue without mention of dorsal or ventral surface to C023 [Anterior 2/3 of tongue, NOS].
Code Primary Site for case 3 to C022 [Ventral surface of tongue]. The underside of the tongue is specified as the site of the biopsy in case 3.
CS Tumor Size--Ovary: The size of a cyst is not coded in this field. However, can the size of a "cystic mass" be coded in this field? See Discussion.
The specimen consists of a cystic mass which weighs 1520 grams and measures 23 x 17 x 10 cm.
If the tumor is described as a "cystic mass" and only the size of the entire mass is given, code the size of the entire mass, because the cysts are part of the tumor itself.
Please note: Ovarian cancer stage is not based on tumor size.
