Inquiry Details
References:
2021 SEER Manual, 186. Reason for No Surgery of Primary Site
Question:
First Course Treatment/Reason for No Surgery of Primary Site: How should we be coding Reason For No Surgery of Primary Site for cases where surgery was planned but ultimately cancelled due to progression? See Discussion.
Discussion:
There is a discrepancy in the SEER and STORE manual definition of code 2 for Reason for No Surgery of Primary Site. STORE includes progression of tumor prior to planned surgery as part of the definition for code 2, but the SEER Manual does not. The progression statement is included in the SEER Manual (2018 and 2021) for Reason for No Radiation, but not for Reason for No Surgery.
Answer:
Assign code 2 for cases where surgery was planned but ultimately cancelled due to progression in the data item Reason For No Surgery of Primary Site. Code 2 description contains examples and is not exhaustive of reasons for no surgery.
We will add the example for consistency in the next version of the SEER manual.
