CS Eval/Surgery of Primary Site--Colon: When the only procedure performed is a polypectomy, if there is NO tumor at the margins, should CS TS/EXT-Eval be coded as 3 and the surgery coded as a polypectomy?
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 eval code 3. A polypectomy with no tumor at the margin meets the criteria for pathologic staging.
Code polypectomy in Surgery of Primary site in this case.
Reportability--Brain and CNS: Does a neurofibroma actually arise in peripheral nerve roots like a schwannoma even if it is referred to as a "C6-T1 intradural spinal cord tumor" and is therefore not reportable?
Schwannomas and neurofibromas of the peripheral nerves are not reportable. Schwannomas of the nerve root or spinal dura are reportable.
Reporting Source: If the only patient record available for a physician office biopsy is the pathology report identified from a freestanding laboratory, is reporting source coded to 3 [Laboratory Only (hospital-affiliated or independent)] or 4 [Physicians office/Private Medical Practitioner (LMD)]? See Discussion.
A case was identified through a pathology report from a freestanding lab. The doctor who submitted the specimen left the state. His records cannot be located. Because the patient had the specimen removed at a physician's office, not at a path lab, is Type of Reporting Source field coded to the physicians office?
Reporting Source is the source that provided the best information used to abstract the case.
For this case, assign code 3 [Laboratory Only (hospital-affiliated or independent)]. Reporting source should reflect the lab where this case was identified. The MD office added nothing to the case, not even a confirmation of malignancy.
Systemic/Surgery Sequence--Breast: How is this field coded for a breast cancer patient treated with a lumpectomy followed by chemotherapy and then a mastectomy?
Assign code 2 [Systemic therapy before surgery]. The code in Systemic Treatment/Surgery Sequence is related to the surgery coded in Surgery of Primary Site. For SEER, the mastectomy will be coded in the surgery field. The chemotherapy occurred before the mastectomy.
Multiple Primaries (Pre-2007)--Breast: How many primaries are to be abstracted when each of multiple breast "re-excisions" performed more than two months apart in 2006 demonstrate intraductal carcinoma and there is no mention of "recurrence"? See Discussion.
Right Breast
06/27/2002 exc bx, DCIS. Margins involved.
09/24/2002 re-exc, several foci of intraductal ca. Margins involved.
10/15/2002 re-exc, microfocus of DCIS
Radiation treatment started 11/18/2002.
Is this 1, possibly 2, or maybe 3 breast primaries because of the 2 month rule and no statement of "recurrence"? Based on SINQ #20000478, this would be at least 2, but possible 3 primaries. Based on SINQ #20021143, this would be 1 primary if the case were diagnosed from 1998-2003. The excisions appear to represent wider excisions of the same tumor.
For cases diagnosed prior to 2013:
For tumors diagnosed prior to 2007, this is one primary, assuming these are wider excisions of the same 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.
First Course Treatment--Liver: Given that agents can be used that are not chemotherapy drugs, how should treatment be coded for a procedure called a "chemoembolization" when the agent used is not documented?
This issue was discussed among the national standard setters and per the SEER website this issue has been resolved as follows: When "chemoembolization" is done but the agents used are not chemotherapy drugs, then treatment should be coded as "Other Therapy." See http://seer.cancer.gov/tools/codingmanuals/embolization.html
CS Tumor Size/CS Extension--Prostate: Because prostatectomy results are excluded from the CS Extension field for prostate, is code 95 [No evidence of primary tumor] accurate to reflect bilateral lobe involvement of prostate cancer when it is incidentally found following a radical cystectomy for a bladder primary? Why must tumor size be 000 when the CS Extension code is 95?
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.Code prostate CS Extension to 99 [Extension unknown] and code CS Tumor Size according to the information available from the surgery.
CS Extension code 95 [No evidence of primary tumor] should be used only in that rare situation when the only evidence of disease is distant mets or lymph node involvement, no primary tumor found. That is why CS tumor Size must be 000 when CS Extension code 95 is used.
MP/H Rules/Multiple Primaries--Bladder/Renal Pelvis: Is a non-invasive papillary transitional cell carcinoma of the bladder diagnosed one year after the occurrence of an invasive papillary transitional cell carcinoma of the renal pelvis reported as one or two primaries?
For cases diagnosed 2007 or later:
This is a single primary with renal pelvis as primary site.
Use the 2007 MP/H rules to determine if the 2007 diagnosis is a new primary. Use the Urinary rules, multiple tumors module. Start with rule M3. Follow the rules down to Rule M8 and stop. This is an example of implantation effect.
MP/H Rules/Histology--Colon: Regarding histology rule H21, is there a hierarchy or do you code the higher histology if there is an adenocarcinoma arising in a polyp and an adenocarcinoma in a villous adenoma?
For cases diagnosed 2007 or later:
If you arrive at H21 and have an additional decision to make regarding the use of 8210, 8261 or 8263, you must make another pass through the histology rules. The second pass will determine which of the two or three histology codes to assign. The answer will vary depending of the specifics of the case.
Example:
Transverse colon: Adenocarcinoma in an adenomatous polyp involving muscularis propria and adenocarcinoma in a villous adenoma involving subserosa of transverse colon. Start with rule H15 because there are multiple tumors. Stop at H21 -- code either 8210 or 8261. To decide between 8210 and 8261, make a second pass through the histology rules, starting again with H15. Stop at H20. Code the histology of the most invasive tumor, 8210 [Adenocarcinoma in adenomatous polyp].
