-3677 Format Fatal Values of Date Items:
This item must contain either (a) a valid date in YYYYMMDD format, or (b) one of the special values (if any) that are listed in the "Item Values" table of the Detailed Data Specifications Report.

Note that if a date in YYYYMMDD format is submitted, it must be 8 characters in length and each of the 8 characters must contain the digits 0 (zero) through 9. YYYY, MM, and DD must be zero filled, where necessary. For example, January 1, 2011 must be submitted as "20110101".
-3658 Consistency Fatal Coding of A0410 depends upon the resident's status on the target date for the assessment. The target date is defined as follows:

a) If A0310F is equal to [01], then the target date is equal to A1600 (entry date).
b) If A0310F is equal to [10,11,12], then the target date is equal to A2000 (discharge date).
c) If A0310F is equal to [99], then the target date is equal to A2300 (assessment reference date)..

Given the target date, the following rules apply:

a) If the resident is on a Medicare/Medicaid certified unit on the target date for the assessment, then A0410 must be equal to [3] (federal required submission).

b) If the resident is on a unit that is not Medicare/Medicaid certified on the target date and if the State requires MDS submission for individuals on the resident's unit, then A0410 must be equal to [2] (state but not federal required submission).

c) If the facility is completing the assessment for another purpose (other than to satisfy Federal or State requirements), then A0410 must be equal to [1] (neither federal nor state required submission).

If A0410 is equal to [2,3], then the assessment MUST be submitted to the MDS Submission System. If A0410 is equal to [1], then the assessment MUST NOT be submitted to the MDS Submission System.

NOTE: It is a violation of a resident's right to privacy to submit data to CMS's data systems when the data are not required.
-3668 Consistency Fatal a) If A2300 (assessment reference date) minus A1600 (entry date) is greater than or equal to 14 days, then the following items in Column 1 must be equal to [^]: O0100A1, O0100B1, O0100C1, O0100D1, O0100E1, O0100F1, O0100G1, O0100H1, O0100I1, O0100J1, O0100K1, O0100M1, O0100Z1.

b) If A2300 (assessment reference date) minus A1600 (entry date) is less than or equal to 13 days, then the following items in Column 1 must be equal to [0,1,-]: O0100A1, O0100B1, O0100C1, O0100D1, O0100E1, O0100F1, O0100G1, O0100H1, O0100I1, O0100J1, O0100K1, O0100M1, O0100Z1.
-3749 Consistency Warning Date Span Requirements
The following rules describe allowable spans between pairs of dates. Each rule applies if both date items in the pair are active and contain valid dates (not dashes or other special values). Violation of these rules will result in warnings.

a) Z0500B (completion date) - A2300 (assessment reference date) <= 14 days.

b) If A0310A is equal to [03,04,05], then V0200B2 (CAA process signature date) - A2300 (assessment reference date) <= 14 days.

c) V0200C2 (CAA care plan signature date) - V0200B2 (CAA process signature date) <= 7 days.

d) If A0310A is equal to [01], then Z0500B (completion date) - A1600 (entry date) <= 13 days.

e) If A0310A is equal to [01], then V0200B2 (CAA process signature date) - A1600 (entry date) <= 13 days.
-3762 Consistency Warning ***NOTE: THIS EDIT HAS BEEN SUSPENDED AND WILL NOT BE APPLIED TO SUBMITTED RECORDS UNTIL FURTHER NOTICE.

If O0250B is active and contains a valid date (is not equal to [-,^]), then it should contain a date that is in the appropriate date range, as defined below. Determination of the appropriate date range depends upon the target date for the assessment. The target date is defined as follows:

a) If A0310F is equal to [01], then the target date is equal to A1600 (entry date).
b) If A0310F is equal to [10,11,12], then the target date is equal to A2000 (discharge date).
c) If A0310F is equal to [99], then the target date is equal to A2300 (assessment reference date).

Given the target date, the following rules apply:

a) If the target date falls within an ongoing influenza season, then the value of O0250B should be greater than or equal to the starting date of the current influenza season and less than or equal to the target date.

b) If the target date falls outside of an ongoing influenza season, then the edit described above in (a) will be suspended and no warning will be issued based upon the value of O0250B.

Note that the dates that define the "current influenza season" will be defined each year by CMS and will be published in updates to the MDS user's manual. Note also that violation of the consistency rule described in this edit will result in a warning.
-3778 Consistency Fatal Completion of A1550A through A1550Z.

a) If A0310A is equal to [02,06,99], then A1550A through A1550Z must equal [^].
b) If the resident's age is 22 years of age or older and A0310A is equal to [01], then A1550A through A1550Z must not equal [^].
c) If the resident's age is 22 years of age or older and A0310A is not equal to [01], then A1550A through A1550Z must equal [^].
d) If the resident's age is 21 years of age or younger and A0310A is equal to [01,03,04,05], then A1550A through A1550Z must not equal [^].

For the rules above, age should be computed in the following way using A0900 (birth date) and A2300 (assessment reference date):

a) If only the year is submitted in A0900, then replace the month and day with "0702" (July 2, the midpoint of the year) for the purpose of calculating age.
b) If only the year and month are submitted in A0900, replace the day with "15", (the midpoint of the month) for the purpose of calculating age.
c) Provisionally compute age (in years) by subtracting the year in A0900 (as modified above, if necessary) from the year in A2300.
d) If the month in A2300 is less than the month in A0900, then subtract 1 from the provisional age computed in (c) above.
e) If the month in A2300 is equal to the month in A0900 and if the day in A2300 is less than the day in A0900, then subtract 1 from the provisional age
computed in (c) above.
-3819 Consistency Fatal a) If A2300 (assessment reference date) minus A1600 (entry date) is greater than or equal to 7 days, then the following items in Column 1 must be equal to [^]: K0510A1, K0510B1, K0510C1, K0510D1, K0510Z1.
b) If A2300 (assessment reference date) minus A1600 (entry date) is less than or equal to 6 days, then the following rules apply:
---b1) If the following items in Column 1 are active, they must not equal [^]: K0510A1 and K0510B1.
---b2) If A0310G=[2] and A0310A=[99] and A0310B=[99], then if the following items in Column 1 are active, they must equal [^]: K0510C1, K0510D1 and K0510Z1.
---b3) If A0310G=[2] and (A0310A=[01,02,03,04,05,06] or A0310B=[01,02,03,04,05,06,07]), then if the following items in Column 1 are active, they must not equal [^]: K0510C1, K0510D1 and K0510Z1.
---b4) If A0310G=[1,^], then if the following items in Column 1 are active, they must not equal [^]: K0510C1, K0510D1 and K0510Z1.
-3851 Consistency Fatal Date Item Consistency Rules
Date items fall into four groups, designated Group A, B, C, and D below. Each group has its own consistency rules.

------------------------------------------

GROUP A RULES (Edit 3851a)
Group A items are listed below. Each active item in this list that contains a valid date (not blank or dashes) must be in the specified order:

A0900 (birthdate) <=
A1900 (admission date) <=
A1600 (entry date) <=
A2300 (assessment reference date) = A2000 (discharge date) <=
Z0500B (date RN signed assessment as complete) <=
V0200B2 (CAT assessment process signature date) <=
V0200C2 (CAT care planning signature date) <=
X1100E (correction: attestation date) <=
current date

------------------------------------------

GROUP B (Edit 3851b)

Group B items are listed below. Each active item in this list that contains a valid date (not blank or dashes) must obey all of the following rules:

1. Each Group B date must be greater than or equal to A0900 (birthdate).
2. Each Group B date must be less than or equal to A2300 (assessment reference date) if A2300 is active.
3. If A0310F is equal to [10,11,12] (if A2000 discharge date is completed), then each Group B date must be less than or equal to A2000.
4. For start/end date pairs shown below, the start date must be less than or equal to the end date.
5. Otherwise, the Group B dates may be in any order.

The following is a list of Group B dates:
A2400B <= A2400C (Medicare stay start/end)
M0300B3 (date of oldest Stage 2 pressure ulcer)
O0250B (date influenza vaccine received)
O0400A5 <= O0400A6 (speech-language audiology therapy start/end)
O0400B5 <= O0400B6 (occupational therapy start/end)
O0400C5 <= O0400C6 (physical therapy start/end)
V0100C (prior assessment reference date)

------------------------------------------

GROUP C RULES
The Group C rules only apply to records where A0310A = [05, 06] (significant correction to prior comprehensive or quarterly).

RULE C1 (Edit 3851c1)
If A0310A = [05, 06] and A1700=[1] (admission), then Rule C1 applies:
A1600 (entry date) <=
A2200 (previous ARD for significant correction)<=
A2300 (assessment reference date)

RULE C2: (Edit -3851c2)
If A0310A = [05, 06] and A1700=[2] (reentry), then Rule C2 applies:
A0900 (birthdate) <=
A2200 (previous ARD for significant correction) <=
A2300 (assessment reference date)

------------------------------------------

GROUP D (Edit 3851d)

The Group D items include the following:

O0400A5, O0400B5, and O0400C5 (therapy start dates)
O0400A6, O0400B6, and O0400C6 (therapy end dates)

If any of these 6 items contains a valid date (not [-,^,--------]), then each of those dates must be greater than or equal to A1600 (entry date).
