OASIS-E2 is coming…Are you ready?
Healthcare compliance is always evolving, and the latest OASIS revision for home health is almost here.
The Outcomes and Assessment Information Set (OASIS) and its associated Guidance Manual are periodically revised based on the Center for Medicare and Medicaid Services (CMS) addition or removal of quality measures from the Home Health Quality Reporting Program (HHQRP), or for other program requirements. Typically, OASIS version changes are proposed and finalized through annual home health rulemaking, which is based on a calendar year (CY) with a January 1st implementation date.
The last OASIS revision implemented by CMS was the version change from OASIS-E to OASIS-E1, which was approved by the Office of Management and Budget (OMB) on December 11, 2024, and implemented on January 1, 2025.
CMS additionally ended the temporary suspension of OASIS data collection on non-Medicare/non-Medicaid home health agency (HHA) patients and implemented all-payor OASIS reporting requirements in this current CY 2025, which were phased in through a voluntary period from January through June, and became mandatory on July 1, 2025.
In this blog, we explore past OASIS changes and what’s coming so your agency can be ready.
CY 2025 HH Final Rule
With the passing of the CY 2025 HH Final Rule, CMS finalized the collection of four new social determinants of health (SDOH) items:
- One living situation
- Two food items
- One utilities item
- And the modification of the transportation item at A1250, beginning with the CY 2027 HHQRP via the OASIS
CY 2026 HH Proposed Rule
This year, outlined in the CY 2026 HH Proposed Rule, CMS is now proposing to remove the four new SDOH items previously finalized but not yet implemented, and to remove the Patient/Resident COVID-19 Vaccine measure beginning with the CY 2026 HHQRP.
CMS proposes that, effective with assessments completed on or after the date of publication of the CY 2026 HH PPS final rule, the data from the “Patient/Resident COVID-19 Vaccination is Up to Date” OASIS item (O0350) would no longer be used in the calculation of the Patient/Resident COVID-19 Vaccine measure, and the measure itself would be withdrawn.
Additionally, CMS proposes that the Patient/Resident COVID-19 measure rates would be publicly reported for the last time with the January 2026 Care Compare refresh on Medicare.gov, based on data from Q1 of 2025.
Here comes OASIS-E2…Get ready!
As of July 2025, CMS has released a Paperwork Reduction Act (PRA) notice and is seeking approval from the OMB, proposing an off-cycle version change from OASIS-E1 to OASIS-E2. This OASIS-E2 PRA package contains a zip file that includes four documents:
- Supporting Statement – Part A
- Attachment A – OASIS-E1 to OASIS-E2 Change Table
- Attachment B – All-Items Version of OASIS-E2 (Proposed Data Collection)
- Attachment C – Itemized list of time points and OASIS-E2 assessment items (Proposed Data Collection)
In the supporting statement, CMS provides a summary of upcoming changes to OASIS that are proposed to be implemented on April 1, 2026.
Summary of additions to and removals from the OASIS data set for version E2
The OASIS-E2 is scheduled for implementation on April 1, 2026, to comply with changes from annual rulemaking and sub-regulatory changes. The changes in OASIS-E2 include:
- The removal of the A1250 Transportation item, which will be replaced by the revised A1255 Transportation item to align with a similar item used in other CMS programs (as finalized in the CY 2025 HH Final Rule)
- The item O0350 ‘Patient’s COVID-19 Vaccination is Up to Date’ will be removed in OASIS-E2 (as proposed in the CY 2026 HH Proposed Rule)
Additional sub-regulatory changes indicated in this PRA include:
- CMS adding the B1000 Hearing, B0200 Vision, and A1110 Language items to the Resumption of Care (ROC) timepoint
- A0810 Sex will replace the M0069 Gender item
As we all know, OASIS accuracy is critical, as it is tied to PDGM payment and publicly reported quality outcomes, which is why it’s important to be prepared when OASIS-E2 officially begins.
