2202.4A - Comprehensive Assessment and OASIS Collection
(Rev. 125, Issued: 10-31-14, Effective: 10-31-14, Implementation: 10-31-14)
The comprehensive assessment regulations require a comprehensive assessment (that
includes certain OASIS data items) be conducted at specific time points during a patient’s
admission. Those specific times are:
1. SOC
After admission to the HHA, the SOC comprehensive assessment should be completed
in a timely manner consistent with the patient’s immediate needs but no later than 5
calendar days after the SOC.
2. ROC
The comprehensive assessment is completed within 48 hours of the patient’s return to
the place of residence or of the HHA’s knowledge of the patient’s return after an
inpatient admission of 24 hours or more for any reason other than diagnostic tests.
This applies when the patient was not discharged from the HHA during the inpatient
admission. If the physician’s order requests that the HHA resume care at a point later
than 48 hours or if the patient refuses a visit within this 48-hour period, a note to this
effect should be documented in the patient’s chart for future reference.
3. Follow-Up - The comprehensive assessment that is performed at the end of the
current 60-day period. This assessment must be performed within the last 5 days of
the current 60-day episode. For example:
Start of Care
Certification Period
Follow-Up Assessment Due
1/15/20xx
1/15/20xx - 3/14/20xx
3/10/20xx - 3/14/20xx
1/15/20xx
3/15/20xx - 5/13/20xx
5/09/20xx - 5/13/20xx
1/15/20xx
5/14/20xx - 7/12/20xx
7/08/20xx - 7/12/20xx
4. Transfer to an Inpatient Facility
An assessment update is performed when a patient is transferred to an inpatient facility
for 24 hours or more for any reason except diagnostic testing, regardless of whether
the patient is discharged from the HHA at that time. The update must be completed
within 48 hours of the patient’s transfer to the inpatient facility or within 48 hours after
the HHA becomes aware of the transfer and includes a limited number of OASIS
items.
5. Discharge
The comprehensive assessment is performed when a patient is discharged from home
care. These updates must be completed within 48 hours of the discharge/death or
within 48 hours after the HHA becomes aware of the discharge/death.
2202.4B - OASIS Encoding and Locking
(Rev. 125, Issued: 10-31-14, Effective: 10-31-14, Implementation: 10-31-14)
HHAs should use HAVEN or HAVEN-like software to encode or enter OASIS data into
their computers. HAVEN will accommodate data entry of OASIS items from all required
time points. Regardless of the time point, OASIS data items should be encoded, and
checked for errors using HAVEN or HAVEN-like software, and made
export/transmission-ready.
1. Availability of HAVEN
The HAVEN software is available for downloading free of charge from the CMS OASIS
and QIES Technical Support (QTSO) Web site. See
https://www.qtso.com/havendownload.html
The HAVEN help line can be reached at: 1-877-201-4721.
Specific information describing how to operate the HAVEN software can be found at
https://www.qtso.com/download/haven/hhahelp32.pdf.
2. Errors and Warnings in Encoding
See Error Messages and Description Guide --
https://www.qtso.com/download/Guides/hha/errors/Errors_sec2.pdf
HHAs may experience two types of messages at completion of data entry.
a. Error Message.
If the HHA uses HAVEN for data entry, an error message may occur if a
mandatory field is left blank. The HHA will receive an error that the field must be
filled in before the assessment can be marked as complete. HHAs should correct
their errors before an assessment may exported to the OASIS Data Management
System. Along with the error message is the name of the window tab where the
error was detected.
b. Warning Message
If the HHA uses HAVEN for data entry, a warning message may occur if timing
criteria for date fields do not match OASIS data specifications. These messages
are informational only and do not preclude an HHA’s assessment from being
exported. Along with the warning message is an explanation of that message and
direction on where the discrepancy was detected.
2202.4C - OASIS Reporting (Refer to §484.20)
(Rev. 125, Issued: 10-31-14, Effective: 10-31-14, Implementation: 10-31-14)
1. HHA Submissions
HHAs must submit their OASIS data within 30 days of the M0090 date, date
assessment completed. Data received outside of this time frame is considered
overdue. Specific information describing how HHAs are to transmit OASIS data to
the SA is in the OASIS System Users Guide.
2. Errors and Warnings in OASIS Reporting
When submitting OASIS records, a fatal error message may occur if the HHA’s data
record layout does not follow OASIS data specifications. This message should not
occur if the HHA is using the HAVEN software to encode the OASIS items.
3. SA Access
In States where the non-long term care agency is in a location separate from the
OASIS State System (where the MDS Data System resides and is not under the direct
jurisdiction of the home health survey agency), CMS provides access to the OASIS
State System by installing a computer work station at the home health survey agency
address to link to the OASIS State System.
The CMS will provide additional support to the SA to access and operate the off-site
server by providing appropriate software, and technical assistance from CMS and the
CMS OASIS contractors.
