CS Site Specific Factor--Prostate: Are the EOD guidelines developed for coding apex involvement still in effect for determining the code for apical involvement in SSF 4? See Discussion.
How do the old prostate codes 31, 33, and 34 correspond to the new SSF 4 field? Because "arising in" or "extending into" apex is rarely, if ever, stated, previous SEER guidelines instructed us to use code 33 for "apex only" involvement, and code 34 for "apex and any other area of prostate". Code 31 [into/arising, NOS] was to be avoided.
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, the EOD guidelines for coding apex involvement are not in effect for coding SSF4.
The codes for CS site specific factor 4 include code 2 [into prostatic apex/arising in prostatic apex, NOS]. When it cannot be determined if apical involvement is arising in, or extending to, the apex, use code 2.
Primary Site/Priorities--Breast: When there are conflicting references to subsite in different reports, which report has priority? See Discussion.
The clinical site of the palpable mass is outer quadrant. The pathologist states inflammatory breast cancer located in the central breast. Should the site be coded to C501 for central breast, C509 for inflammatory breast ca, or C508 for outer quadrant?
Code the breast subsite from the pathology report (C501, central).
The priority order for coding subsite from conflicting reports is
1. Pathology report
2. Operative report
3. Physical examination
4. Mammogram, ultrasound
The primary site of inflammatory breast carcinoma is coded to C509 when there is no palpable tumor.
CS Lymph Nodes: Are lymphatic channels/vessels within an organ coded as regional lymph nodes?
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.Lymphatic channels/vessels carry lymph fluid throughout the organs and tissues of the body. Lymph channels/vessels within an organ are not nodes. Lymph channels/vessels outside an organ are not nodes.
CS Lymph Nodes/CS Site Specific Factor 3--Breast: How are positive intramammary lymph nodes reflected in these fields? See Discussion.
Patient with breast cancer underwent mastectomy. No axillary lymph nodes were positive, but 1 out of 2 intramammary lymph nodes were positive for mets (greater than 2 mm). CS Lymph node codes describe axillary and internal mammary nodes, but do not describe intramammary lymph nodes.
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.
Intramammary lymph nodes are coded as axillary lymph nodes for staging purposes. Intramammary node are nodes within the breast tissue. Both staging and treatment suggest these are equivalent to axillary nodes.
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].
CS Lymph Nodes--Breast: How is this field to be coded if the pathologist staged the case pN1a and the lymph node is stated to be negative on H&E, is .3 cm on IHC stain for pancytokeratin but on review of smears shows no malignant cells?
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 CS Lymph Nodes as negative [00]. The positive stain for pancytokeratin is contradicted by the statement "malignant cells are not identified." See also sinq 20010055.
Surgery of Primary Site--Skin: What surgery code is used to reflect the amputation of a finger for subungual melanoma?
47 [Wide excision or reexcision of lesion or minor (local) amputation with margins greater than 2cm] is the correct surgery code for amputation of a finger for melanoma.
CS Extension/CS Mets at Dx--Colon: How is a small focus of metastatic disease in the submucosa coded for a sigmoid primary? See Discussion.
Path final diagnosis states: "No lymph node metastases identified. One submucosal met in a block taken from a surgical margin section." Path micro states: "Microscopic involvement of the border between the serosa and muscularis propria. Sections of proximal & distal surgical margins reveal no tumor in one, and a small focus of metastatic disease in the submucosa of the other. This focus of tumor exists in a small vascular channel and is complete in and of itself; ie, it has not been cut thru by excision of the specimen from the patient."
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.
This submucosal metastasis does not affect CS extension. It is not part of CS or TNM staging.
According to the TNM supplement, "Multiple tumour foci in the mucosa or submucosa ("skip metastasis") are not part of the TNM classification and should not be classified as distant metastasis.
2004 SEER Manual Errata/Surgery of Primary Site--Lymphoma: Item 9.a on page 178 is incorrect. Do not assign surgery code 98 to lymphoma, primary in lymph nodes. See Appendix C, page C-707 for Lymphoma (primary in lymph nodes) surgery codes.
Delete item 9. a. i. ii. and iii. on page 178 of the 2004 SEER Manual. This correction will be included in the next errata.
CS Lymph Nodes--Prostate: How is this field coded when no scan, scope or surgical evaluation of regional lymph nodes is performed for a case with localized disease in the primary site? See Discussion.
Prior to initiation of collaborative stage, SEER prostate guidelines instructed us to code lymph node involvement as negative when clinical or pathologic extension was coded 10-34 and there was no lymph node information. Is this guideline still in effect, or do we follow the collaborative stage rules which require lymph node information or, in absence of node info, usual treatment for localized disease?
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.For prostate and other "inaccessible sites" with localized disease, code the regional lymph nodes as clinically negative when not mentioned on imaging or exploratory surgery.
