Acsn/Class/Seq Override

The edit, Accession Number, Class of Case, Seq Number (CoC), checks the following:

• If the case is the only case or the first of multiple cases diagnosed at the facility (ACoS Sequence Number = 00, 01, 60 or 61, and Class of Case = 0, 1, or 6), then the first 4 characters of the Accession Number must equal the year of the Date of First Contact.

• If the case is first diagnosed at autopsy (Class of Case = 5), and the case is the only case or the first of multiple cases for a patient (ACoS Sequence Number = 00, 01, 60, or 61), then the first 4 characters of the Accession Number must equal the year of the Date of Last Contact or Death AND must equal the year of the Date of First Contact.

• If the case is first diagnosed at autopsy (Class of Case = 5), and the case is the second or more case for a patient (ACoS Sequence Number greater than 01 or greater than 61), then the year of the Date of First Contact must equal the year of Date of Last Contact or Death.

There are some exceptions to the above rules. Override Acsn/Class/Seq may be used to override the edit when the circumstances fit the following situation or one similar to it:

• The case may be the only or the first of multiple malignant cases for a patient (ACoS Sequence Number = 00 or 01), but there is an earlier benign case (with an earlier year of the Date of First Contact) for which the Accession Number applies.

Instructions for Coding

• Leave blank if the EDITS program does not generate an error message for the edit Accession Number, Class of Case, Sequence Number (CoC).

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

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