Since the designation of in situ is very specific and almost always requires microscopic confirmation, ordinarily specific information should also be available regarding the primary site. Conversely, if inadequate information is available to determine a specific primary site, it is unlikely that information about a cancer being in situ is reliable.

  • If a specific in situ diagnosis is provided, try to obtain a more specific primary site. A primary site within an organ system can sometimes be identified based on the diagnostic procedure or treatment given or on the histologic type. If a more specific site cannot be determined, it is usually preferable to code a behavior code of 3. In the exceedingly rare situation in which it is certain that the behavior is in situ and no more specific-site code is applicable, set Override Site/Behavior to 1.

Instructions for Coding

  • Leave blank if the EDITS program does not generate an error message for the edit Primary Site, Behavior Code (CoC) and/or the edit Primary Site, Behavior Code ICD-O-3 (CoC).

  • Leave blank and correct any errors for the case if an item is discovered to be incorrect.

  • Code 1 if review of all items in the error or warning message confirms that all are correct.
