This data field applies only to cancers diagnosed before 2003. Collection of this data item was discontinued as of 1/1/2003 with FORDS implementation.
Record the number of regional lymph nodes microscopically examined in the pathology report DURING THIS SURGICAL PROCEDURE ONLY. DO NOT add numbers of nodes removed at different surgical events.
If no regional lymph nodes are identified in the pathology report, code 00 even if the surgical procedure includes a lymph node dissection (i.e., modified radical mastectomy) or even if the operative report documents removal of nodes.
Because this field is not cumulative and not affected by timing, it does not necessarily replace or duplicate the field "Regional Lymph Node Examined." Use the Surgical Codes in Appendix G to identify the regional lymph nodes for each site.
Code | Description |
|---|---|
00 | No regional lymph nodes removed |
01 | One regional lymph node removed |
02 | Two regional lymph nodes removed |
-- | |
90 | Ninety or more regional lymph nodes removed |
95 | No regional lymph node(s) removed but aspiration of regional lymph node(s) was performed. |
96 | Regional lymph node removal documented as a sampling and number of lymph nodes unknown/not stated. |
97 | Regional lymph node removal documented as dissection and number of lymph nodes unknown/not stated. |
98 | Regional lymph nodes surgically removed but number of lymph nodes unknown/not stated and not documented as sampling or dissection. |
99 | Unknown; not stated; death certificate ONLY |
Use code 95 for a lymph node aspiration when the cytology or histology is positive for malignant cells.
Use code 99 if information about regional lymph nodes is unknown, or if the field is not applicable for that site or histology, i.e., unknown primaries (C80.9).
