Consistency Required

1. If RECTYPE D:
*a. Field is active if AA8a = 08.
b. Field is facility option if AA8a = 06 or 07.

2. For the RECTYPEs listed as facility option and for RECTYPE D with AA8a = 06 or 07, the field may be submitted under the optional submission provision given in the Section AB General Notes.

*3. If this date is present in the record (not blank), it must be earlier than or the same as all of following dates that are present in the record (not blank): P_REC_DT, AT6, AB11, A3a, A4a, R2b, R4, VB2, and VB4. If this date is present, then it must be earlier than or the same as the current date.

4. Additional sequential date relationships involving this date are given in the consistency requirements for the following other dates: AA3.

5. If (a) the record is an admission assessment (AA8a = 01) and (b) no discharge prior to completing the admission assessment (AA8a = 08) has intervened between AB1 and this admission assessment, then:
a. AB1 should not be more than 14 days earlier than R2b.
b. AB1 should not be more than 14 days earlier than VB2.
If either of these relationships is violated, then the MDS assessment process has not been completed in timely fashion and a warning message will be issued.

6. If the record is an admission assessment (AA8a = 01) and the AB1 (admission date) equals the AB1 (admission date) on a prior admission assessment record in the state database, then it appears that a repeat admission assessment has been submitted and a warning message will be issued.
