- Pathology
- Total Number of Pelvic Nodes Examined: 2
- Number of Pelvic Sentinel Nodes Examined: 2
- Total Number of Para-Aortic Nodes Examined: 0
- Number of Para-Aortic Sentinel Nodes Examined:0
Review how the following fields are coded in this scenario:
| Scope of Regional LN Surgery NAACCR #1292 | 2 Sentinel lymph node biopsy [only] | STORE/ SEER It doesn’t matter what the primary site is, if the operative report states that a SLN BX was performed, assigning the appropriate code(s) of 2, 6, or 7. |
| AJCC Path N Suffix NAACCR #1035 | (sn) | STORE It doesn’t matter what the primary site is, assign (sn) to denote a Sentinel node procedure is performed in the absence of complete dissection. |
| Regional Lymph Nodes Positive NAACCR #820 | 00 | STORE/SEER This field is used to record the exact number of regional lymph nodes examined by the pathologist and found to contain metastases. |
| Regional Lymph Nodes Examined NAACCR #830 | 02 | STORE/SEER This field records the total number of regional lymph nodes that were removed and examined by the pathologist. |
| Date Regional Lymph Node Dissection NAACCR #682 | BLANK | STORE/SEER Records the date of the non-sentinel regional node dissection was performed. This case, only sentinel lymph nodes removed, thus this field will be left BLANK. Leave Date of Regional Lymph Node Dissection blank when only a sentinel lymph node biopsy is performed. |
| Sentinel Lymph Nodes Positive NAACCR #835 | BLANK | STORE/SEER This field is used to record the number of SLN positive for for breast and cutaneous melanoma cases only. For all other sites, leave this field BLANK. |
| Sentinel Lymph Nodes Examined NAACCR #834 | BLANK | STORE/SEER This field is used to record the number of SLN examined for for breast and cutaneous melanoma cases only. For all other sites, leave this field BLANK. |
| Date of Sentinel Lymph Node Biopsy NAACCR# 832 | BLANK | STORE/SEER This field is used to record the date of SLN biopsy for for breast and cutaneous melanoma cases only. For all other sites, leave this field BLANK. |
