Report Question ID Question Discussion Answer Year
20071029 CS Lymph Nodes--Kidney, renal pelvis: Under what circumstances would code 80 [Lymph nodes, NOS] be used to document the presence of positive lymph nodes? See Discussion. The CS Schema for Kidney (Renal Parenchyma) states to use code 70 for Regional Lymph Nodes, NOS. The schema for for Renal Pelvis states to use code 50 for Regional Lymph Nodes, NOS. Both schemas have a Code 80, for Lymph Nodes, NOS that maps to N1 in both schemas.

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 80 can be used for positive lymph nodes when you are unable to determine if they are regional or distant. CS Lymph Nodes code 80 is provided for this situation in accordance with the downstaging rule.

Code 80 should be used very infrequently and only when there is no indication whether the involved lymph nodes are regional or distant.

20071115 CS Tumor Size/CS Site Specific Factor--Breast: How do you code the CS Tumor size and SSF6 fields for a breast cancer described as "Paget disease with underlying intraductal carcinoma (4cm x 3.2cm)"?

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.CS Tumor Size: Assign code 040 for tumor size and code SSF6 as 050 [Invasive and in situ components present, size of entire tumor coded in CS TS]. The size of the invasive component is not stated AND proportions of in situ and invasive are not known.

20091077 CS Site Specific Factor--Head & Neck: Can SSF 1-6 be coded using clinical information only, or does the source of information for lymph nodes need to be pathological?

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.CS Site Specific Factors 1 through 6 for head and neck sites may be coded using either clinical or pathologic information.

20051063 Primary Site/CS Tumor Size/CS Extension--Lung: How are these fields coded when a chest CT for lung cancer documents multiple masses in different lobes of the lung? See Discussion.

Example

Chest CT: "Almost complete consolidation of RUL and superior segment of RLL, highly suspicious for malignancy and represents primary bronchogenic carcinoma until proven otherwise. Multiple pulmonary masses bilaterally consistent with metastatic disease."

The physician describes multiple masses throughout RLL and LLL of lung suspicious for met disease, particularly lesion in LLL measuring 2.5 cm. The 2 cm mass in right lung abuts pleura, another mass in RLL measures 2.5 cm, smaller nodules in RLL and another 1 cm lesion abuts the pleura. Bx of a rt supraclavicular LN is positive for met carcinoma c/w lung primary.

Would primary site be coded to RLL because the scan states that the lesions on the right side represent primary bronchogenic carcinoma until proven otherwise and the 2.5 cm lesion in the RLL is the location of the largest tumor on the right? Or should site be coded to right lung, NOS and size to unknown because there is no clear statement as to which lesion on the right represents the primary tumor? If the site is lung, NOS, would CS Extension be coded to 65 to describe the multiple nodules in the RLL?

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.Based on the information provided:

Code primary site C349 [Lung]. Code laterality 1 [Right]. Code CS Tumor Size 999 [Unknown]. Code CS Extension 65 [Separate tumor nodules, same lobe]. Code CS Mets at Dx 39 [Separate tumor nodule in contralateral lung].

20051117 CS Tumor Size--Bladder: Is tumor size coded to 080 when the bladder mass is described as "greater than 8 cm in diameter"?

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.Based on the information provided above, code CS tumor size 080 [8 cm]. Code the information that is avaliable. Since size of tumor is not used to stage bladder cancer, an approximation is adequate.

 2005
20051119 CS Eval--Colon: When the surgical resection occurs after radiation or chemo, how is the tumor size/extension evaluation field coded when there is no mention of the tumor size or extension in the surgical resection pathology report? See Discussion. 6/30/04 CT Scan abd/pelvis: 7.5x7.2 cm large rectal mass with l cm nodular densities in perirectal region probably adenopathy; irregularity of perirectal soft tissue which could be due to tumor infiltration. 7/26/04 Patient has radiation therapy and 5FU. 10/19/04 LAR: MD Adenoca rectum with regional node mets (3/8).

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.Based on the information provided above, code CS Tumor Size and Extension from CT scan. Code CS TS/Ext eval 5 [Surgical resection performed with pre-surgical treatment...size based on clinical evidence].

Code CS lymph nodes using information from resection. Code CS Reg Nodes eval 6 [Regional LN removed...with pre-surgical treatment...based on pathologic evidence].

 2005
20051068 CS Extension--Retinoblastoma: When the degree of extension differs between the retinas, how is extension coded for simultaneous bilateral retinoblastoma?

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 the CS extension code that corresponds to the greatest level of extension seen in either eye, excluding information from enucleation.

Record extension based on enucleation in Site Specific Factor 1.

Record bilateral disease under laterality. For retinoblastomas, bilaterality is not a component or consideration for staging.

20081136 CS Extension--Corpus uteri: Can a suspicious cytology be used to code extension? See Discussion.

Endometrial primary confirmed by biopsy on 10/26/06. Pelvic washing on 11/14/06 was 'suspicious for malignancy.' Resection path the same day stated the primary tumor invades the inner 1/3 of the myometrium.

Can we use the pelvic washing cytology & code CS extension 61 or should CS extension be coded 12?

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 extension code 61 [cancer cells in peritoneal washings] for the case described above.

"Suspicious" is listed as a term indicating involvement. There is no exception noted for cytology reports. See page 122 of the 2007 SEER manual.

20071017 CS Extension--Prostate: Can the phrase "hard, fixed prostate" be interpreted as clinical extracapsular extension and coded to 50 [extension or fixation to other structures]? See Discussion.

Patient had a "hard, fixed prostate" with needle core bx positive for Gleason grade 4+5=9 adenocarcinoma extensively involving gland. PSA was 87.5. Lymphadenectomy showed 3 positive pelvic/obturator lymph nodes. No prostatectomy was done and no physician TNM staging documented.

Do we need a specific clinical description of other organs to which the prostate is fixed in order to code CS Clinical Extension 50, or does the statement "hard, fixed prostate" qualify? If not, how would we code extension for this seemingly advanced cancer?

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 extension code 50 [extension or fixation to adjacent structures] based on the term "fixed." Fixation to a particular structure(s) does not have to be specified in order to use code 50.

Do not use the statement "hard" to determine CS extension.

20071119 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.
