Question:
Tumor Size--Pathologic/EOD 2018: How is Tumor Size--Pathologic coded when Extent of Disease (EOD) Primary Tumor is 800 (No evidence of primary tumor) and there has been no surgery to the primary site? See Discussion.
Discussion:
The SEER Manual states to assign Tumor Size--Pathological code 000 when EOD Primary Tumor is coded to 800 (No evidence of primary tumor) for any schema. However, the definition of Tumor Size--Pathologic states that it records the size of a solid primary tumor that has been resected.
If the primary site has not been resected (does not meet the pathologic staging criteria), then it seems that Tumor Size Pathologic should be 999 when EOD Primary Tumor is coded as 800.
Answer:
Assign code 999 for Tumor Size--Pathologic when there is no surgery of the primary site. Code 999 includes "No excisional biopsy or tumor resection done."
