SeqNo/DxConf Override (IF23)

This edit forces review of multiple primary cancers when one of the primaries is coded to a site other than ill-defined or unknown and is not microscopically confirmed or confirmed by a positive lab test/marker study. It is important to verify that the non-microscopically-confirmed case is indeed a separate primary from any others that may have been reported. If the suspect case is accurate as coded, and the number of primaries is correct, set the Override SeqNo/DxConf flag to 1 so that the case will not appear in future edits as an error. It is not necessary to set the override flag on the patient’s other primary cancers.

If it turns out that the non-microscopically-confirmed cancer is considered a manifestation of one of the patient’s other cancers, delete the non-microscopically-confirmed case. Check the sequence numbers of remaining cases, correcting them if necessary.

Instructions for Coding

• Leave blank if the EDITS program does not generate an error message for the edit Sequence Number/Diagnostic Confirmation.
• 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.
