Record the removal, biopsy, or aspiration of regional lymph node(s) at the time of surgery of the primary site or during a separate surgical event.
- The scope of regional lymph node surgery is collected for each surgical event even if surgery of the primary site was not performed.
- Record surgical procedures which aspirate, biopsy, or remove regional lymph nodes in an effort to diagnose or stage disease in this data item.
- Codes 0-7 are hierarchical. If only one procedure can be recorded, code the procedure that is numerically higher.
- For primaries of the meninges, brain, spinal cord, cranial nerves, and other parts of the central nervous system (C70.0-C70.9, C71.0-C71.9, C72.0-C72.9), code 9.
- For lymphomas (M-9590-9596, 9650-9719, 9727-9729) with a lymph node primary site (C77.0-C77.9), code 9.
- For an unknown or ill-defined primary (C76.0-C76.8, C80.9) or for hematopoietic, reticuloendothelial, immunoproliferative disease (C42.0, C42.1, C42.3, C42.4 or M-9750, 9760-9764, 9800-9820, 9826, 9831-9920, 9931-9964, 9980-9989), code 9.
- Do not code distant lymph nodes removed during surgery to the primary site for this data item. Distant nodes are coded in the data field Surgical Procedure/Other Site.
- Refer to the current AJCC Cancer Staging Manual for site-specific identification of regional lymph nodes.
- If the operative report lists a lymph node dissection, but no nodes were found by the pathologist, code this field 0 (no lymph nodes removed).
- If the patient has two primaries with common regional lymph nodes, code the removal of regional nodes for both primaries.
- If a sentinel lymph node biopsy is attempted and fails to map this should be coded as 2 in the absence of an axillary lymph node dissection.
- If sentinel lymph node biopsy is attempted and fails to map and the patient does have an axillary lymph node dissection, then the correct code would be 6.
Code | Label | Description |
---|---|---|
0 | None | No regional lymph node surgery. No lymph nodes found in the pathologic specimen. Diagnosed at autopsy |
1 | Biopsy or aspiration of regional lymph node, NOS | Biopsy or aspiration of regional lymph node(s) regardless of the extent of involvement of disease. |
2 | Sentinel lymph node biospy | Biopsy of the first lymph node or nodes that drain a defined area of tissue within the body. Sentinel node(s) are identified by the injection of a dye or radio label at the site of the primary tumor. |
3 | Number of regional nodes removed unknown or not stated; regional lymph nodes removed, NOS | Sampling or dissection of regional lymph node(s) and the number of nodes removed is unknown or not states. The procedure is not specified as sentinel nodes node biopsy. |
4 | 1-3 regional lymph nodes removed | Sampling or dissection of regional lymph node(s) with fewer than four lymph nodes found in the specimen. The procedure is not specified as sentinel node biopsy. |
5 | 4 or more regional lymph nodes removed | Sampling or dissection of regional lymph nodes with at least four lymph nodes found in the specimen. The procedure is not specified as sentinel node biopsy. |
6 | Sentinel node biopsy and code 3, 4, or 5, at same time, or timing not stated | Code 2 was performed in a single surgical event with code 3, 4, or 5. Or, code 2 and 3, 4, or 5 were performed, but timing was not stated in patient record. |
7 | Sentinel node biopsy and code 3, 4, or 5 at different times | Code 2 was followed in a subsequent surgical event by procedures coded 3, 4, or 5. |
9 | Unknown or not applicable | It is unknown whether regional lymph node surgery was performed; death certificate-only; for lymphomas with a lymph node primary site; an unknown or ill-defined primary; or for hematopoietic, reticuloendothelial, immunoproliferative, or myeloproliferative disease. |
