1. Interdisciplinary team members should select the ARD
based on the reason for the assessment and compliance with
all timing and scheduling requirements outlined in
Chapter 2.

Coding Instructions


Enter the appropriate date on the lines provided. Do not
leave any spaces blank. If the month or day contains
only a single digit, enter a “0” in the first space. Use
four digits for the year. For example, October 2, 2010,
should be entered as: 10-02-2010.

For detailed information on the timing of the
assessments, see Chapter 2 on assessment schedules.

For discharge assessments, the discharge date item
(A2000) and the ARD item (A2300) must contain the
same date.

Coding Tips

and Special Populations

When the resident dies or is discharged prior to the end
of the observation period for a required assessment, the
ARD must be adjusted to equal the discharge date.

The observation period may not be extended simply because a resident was out of the
nursing home during part of the observation period (e.g., a home visit, therapeutic leave,
or hospital observation stay less than 24 hours when resident is not admitted). For
example, if the ARD is set at day 13 and there is a 2-day temporary leave during the
observation period, the 2 leave days are still considered part of the observation period.

When collecting assessment information, data from the time period of the leave of
absence is captured as long as the particular MDS item permits. For example, if the
family takes the resident to their home for a holiday and the resident falls, the assessor
will capture the fall in J1900: Number of Falls Since Admission/Entry or Reentry or
Prior Assessment (OBRA or Scheduled PPS), whichever is more recent. This
requirement applies to all assessments, regardless of whether they are being completed
for clinical or payment purposes.
DEFINITION
ASSESSMENT
REFERENCE DATE
(ARD)
The specific end-point for the
observation periods in the
MDS assessment process.
Almost all MDS items refer to
the resident’s status over a
designated time period
referring back in time from
the Assessment Reference
Date (ARD). Most frequently,
this observation period, also
called the look-back or
assessment period, is a 7-
day period ending on the
ARD. Observation periods
may cover the 7 days ending
on this date, 14 days ending
on this date, etc.
