Inquiry Details
References:
2025 SEER Manual, 123-125. Behavior Code
Question:
Reportability/Behavior: Our registry collects some borderline (behavior /1) cases that are not reportable to SEER or any other standard setters. Can we assign a behavior code of /2 to these cases?
Discussion:
Answer:
Do not assign a behavior code of /2 to these cases unless you have a way to flag them so that they are not reported to the standard setters as in situ cases. Work with your state central registry to ensure that these cases are not unintentionally included in state case submission.
