The ACoS sequence number represents the order of all primary reportable tumors diagnosed during a patient's lifetime. It counts the occurrence of independent, malignant primaries that are required to be reported to the ACoS for approved cancer programs.

The sequence number 00 indicates that this patient has one primary cancer. The sequence 01 indicates that the case is the first of multiple primaries.

Sequence numbers in the range of 60-88 have a special meaning to ACoS. They are reserved for conditions that are collected by the registry but are not required by ACoS. These include diagnoses required by KCR but not ACoS (such as VIN III, VAIN III, and AIN III, as well as invasive recurrences abstracted after an in-situ cancer.) Pre-invasive carcinomas of the cervix that were diagnosed in 1996 and 1997 will be sequenced in this range also, because they were required by KCR at the time, but not ACoS.

As of January 1, 2004, benign and borderline intracranial tumors became reportable to ACoS as well as KCR. These are sequenced in the 60-88 series.
