Combining PPS Assessments and OBRA Assessments7
SNF providers are required to meet two assessment standards in a Medicare certified nursing facility:
The OBRA standards are designated by the reason selected in item A0310A, Federal OBRA Reason for Assessment, and item A0130F, Entry/Discharge Reporting and are required for all residents.
The PPS standards are designated by the reason selected in item A0310B, PPS Assessment and item A0310H, Is this a SNF Part A PPS Discharge Assessment?
When the OBRA and PPS assessment time frames coincide (except the IPA), one assessment may be used to satisfy both requirements. PPS and OBRA assessments (except

the IPA) may be combined when the ARD windows overlap allowing for a common assessment reference date. When combining the OBRA and PPS assessments, the most stringent requirements for ARD, item set, and CAA completion requirements must be met. For example, the skilled nursing facility staff must be very careful in selecting the ARD for an OBRA Admission assessment combined with a 5-Day assessment. For the OBRA Admission, the ARD must be set between days 1 and 14 counting the date of admission as day 1. For the 5-Day, the ARD must be set for days 1 through 8. However, when combining a 5-Day assessment with the OBRA Admission assessment, the use of the latter end of the OBRA Admission ARD window would cause the 5-Day assessment to be considered late. To assure the assessment meets both standards, an ARD of a day between Day 1 and 8 would have to be chosen in this situation. In addition, the completion standards must be met. While a PPS assessment can be completed within 14 days after the ARD when it is not combined with an OBRA assessment, the CAA completion date for the OBRA Admission assessment (item V0200B2) must be day 14 or earlier. With the combined OBRA Admission/ 5-Day assessment, completion by day 14 would be required. Finally, when combining a PPS assessment with an OBRA assessment, the SNF staff must ensure that all required items are completed.
Some states require providers to complete additional state-specific items (Section S) for selected assessments. States may also add comprehensive items to the Quarterly and/or PPS item sets.
Providers must ensure that they follow their state requirements in addition to any OBRA and/or PPS requirements.
The following tables provide the item set for each type of assessment or tracking record. When two or more assessments are combined, then the appropriate item set contains all items that would be necessary if each of the combined assessments were being completed individually.

Factors Impacting SNF PPS Assessment Scheduling8
Resident Expires Before or On the Eighth Day of SNF Stay
If the beneficiary dies in the SNF or while on a leave of absence before or on the eighth day of the covered SNF stay, the provider should prepare a 5-Day assessment as completely as possible and submit the assessment as required. If there is not a PPS assessment in iQIES, the provider must bill the default rate for any Medicare days. The provider must also complete a Death in Facility Tracking Record (see Section 2.6 for greater detail).
Resident Transfers or Is Discharged Before or On the Eighth Day of SNF Stay
If the beneficiary is discharged from the SNF or the Medicare Part A stay ends (e.g., transferred to another payer source) before or on the eighth day of the covered SNF stay, the provider should prepare a 5-Day assessment as completely as possible and submit the assessment as required. If there is not a PPS assessment in iQIES, the provider must bill the default rate for any Medicare days.
When the Medicare Part A stay ends on or before the eighth day of the covered SNF stay, and the beneficiary remains in the facility, a Part A PPS Discharge assessment is required.
When the beneficiary is discharged from the SNF, the provider must also complete an OBRA Discharge assessment, but if the Medicare Part A stay ends on or before the eighth day of the covered SNF stay and the beneficiary is physically discharged from the facility the day of or the day after the Part A stay ends, the Part A PPS and OBRA Discharge assessments must be combined. (See Sections 2.10 and 2.11 for details on combining a PPS assessment with a Discharge assessment.)
Resident Is Admitted to an Acute Care Facility and Returns
If a Medicare Part A resident is admitted to an acute care facility and later returns to the SNF to resume Part A coverage, the resident requires a new 5-Day assessment, unless it is an instance of an interrupted stay. If it is a case of an interrupted stay (i.e., the resident returns to the SNF and resumes Part A services in the same SNF within the 3-day interruption window), then no PPS assessment is required upon reentry, only an Entry tracking form. An IPA may be completed, if deemed appropriate.
Resident Is Sent to Acute Care Facility, Not in SNF over Midnight, and Is Not Admitted to Acute Care Facility
If a resident is out of the facility over a midnight, but for less than 24 hours, and is not admitted to an acute care facility, a new 5-Day PPS assessment is not required, though an IPA may be completed, if deemed appropriate. However, there are payment implications: the day preceding the midnight on which the resident was absent from the nursing home is not a covered Part A day. This is known as the “midnight rule.” For example, if the resident goes to the emergency room at 10 p.m. Wednesday, day 22 of their Part A stay, and returns at 3 a.m. the next day, Wednesday is not billable to Part A. As a result, the day of their return to the SNF, Thursday,

becomes day 22 of their Part A stay. This means that this day is skipped for purposes of the variable per diem adjustment, described in Chapter 6.
Resident Takes a Leave of Absence from the SNF
If a resident is out of the facility for a Leave of Absence (LOA) as defined on page 2-13 in this chapter, there may be payment implications. For example, if a resident leaves a SNF at 6:00 p.m. on Wednesday, which is Day 27 of the resident’s stay and returns to the SNF on Thursday at 9:00 a.m., then Wednesday becomes a non-billable day and Thursday becomes Day 27 of the resident’s stay.
If the beneficiary experiences a leave of absence during part of the assessment observation period, the facility may include services furnished during the beneficiary’s temporary absence (when permitted under MDS coding guidelines; see Chapter 3).
Resident Discharged from Part A Skilled Services and from the Facility and Returns to SNF Part A Skilled Level Services
In the situation when a beneficiary is discharged from Medicare Part A and is physically discharged from the facility, but returns to resume SNF Part A skilled services after the interruption window has closed, the OBRA Discharge and Part A PPS Discharge must be completed and can be combined (see Part A PPS Discharge in Section 2.5).
On return to the facility, this is considered a new Part A stay (as long as resumption of Part A occurs within the 30-day window allowed by Medicare), and a new 5-Day and Entry Tracking record must be completed. If the resident was discharged return anticipated, no OBRA assessment is required. However, if the resident was discharged return not anticipated, the facility must complete a new OBRA Admission assessment. See Chapter 6, Section 6.7 for greater detail to determine whether or not the resident is eligible for Part A SNF coverage.
However, in the case of an interrupted stay, that is, if a resident leaves the facility and resumes Part A within the 3-day interruption window, only an OBRA Discharge is required. An Entry Tracking record is required on reentry, but no 5-Day is required. If the resident was discharged return anticipated, no OBRA assessment is required. However, if the resident was discharged return not anticipated, the facility must complete a new OBRA Admission assessment.
The beneficiary should be assessed to determine if there was a significant change in status.
Resident Discharged from Part A Skilled Services Is Not Physically Discharged from the Skilled Nursing Facility
In the situation when a resident’s Medicare Part A stay ends, but the resident is not physically discharged from the facility, remaining in a Medicare and/or Medicaid certified bed with another payer source, the facility must continue with the OBRA schedule from the beneficiary’s original date of admission (item A1900) and must also complete a Part A PPS Discharge assessment.
If Part A benefits resume, there is no reason to change the OBRA schedule; the PPS schedule would start again with a 5-Day assessment, MDS item A0310B = 01, unless it is a case of an
interrupted stay—that is, if the resident is discharged from Part A, remains in the facility, and resumes Part A within the 3-day interruption window, no Part A PPS Discharge is completed, nor is a 5-Day required when Part A resumes.
Delay in Requiring and Receiving Skilled Services
There are instances when the beneficiary does not require SNF level of care services when initially admitted to the SNF. See Chapter 6, Section 6.7.
Non-Compliance with the PPS Assessment Schedule
According to Part 42 Code of Federal Regulation (CFR) Section 413.343, an assessment that does not have its ARD within the prescribed ARD window will be paid at the default rate for the number of days the ARD is out of compliance. Frequent late assessment scheduling practices or missed assessments may result in additional review. The default rate takes the place of the otherwise applicable Federal rate. It is equal to the rate paid for the Health Insurance Prospective Payment System (HIPPS) code reflecting the lowest acuity level for each PDPM component and would generally be lower than the Medicare rate payable if the SNF had submitted an assessment in accordance with the prescribed assessment schedule.
Late PPS Assessment
If the SNF fails to set the ARD within the defined ARD window for a 5-Day assessment, and the resident is still on Part A, the SNF must complete a late assessment. The ARD can be no earlier than the day the error was identified.
The SNF will bill the default rate for the number of days that the assessment is out of compliance. This is equal to the number of days between the day following the last day of the available ARD window and the late ARD (including the late ARD). The SNF would then bill the HIPPS code established by the late assessment for the remainder of the SNF stay, unless the SNF chooses to complete an IPA. For example, a 5-Day assessment with an ARD of Day 11 is out of compliance for 3 days and therefore would be paid at the default rate for Days 1 through 3 of the Part A stay and the HIPPS code from the late 5-Day assessment for the remainder of the Part A stay, unless an IPA is completed.
Missed PPS Assessment
If the SNF fails to set the ARD of a 5-Day assessment prior to the end of the last day of the ARD window, and the resident was already discharged from Medicare Part A when this error is discovered, the provider cannot complete an assessment for SNF PPS purposes and the days cannot be billed to Part A.
Errors on a PPS Assessment
To correct an error on an MDS that has been submitted to iQIES, the SNF must follow the normal MDS correction procedures (see Chapter 5).
