Question:
CS Reg LN Pos/Exam: Are lymph nodes coded as positive or negative when the pathology report for a lymph node dissection performed after radiation and chemo reveals that the nodes are negative but they demonstrated previous involvement by cancer? See Discussion.
Discussion:
Scenario: The patient was treated with radiation and chemotherapy prior to resection for esophageal cancer. The pathology report stated, "1/3 nodes c/w treated previous ca."
Answer:
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.Record lymph nodes that are pathologically confirmed as positive in Regional Nodes Positive. Evidence of previous involvement by cancer is not recorded in this data item.
In the above scenario, the lymph nodes are negative according to pathology.
Clinically positive lymph nodes are coded in CS Lymph Nodes.
