When Does the Transition to OASIS-E REALLY Happen? It’s Not January 1st for All Assessments

OASIS-E Effective January 1, 2023

Since the Centers for Medicare & Medicaid Services (CMS) CY 2022 Home Health Final Rule was posted in fall of 2021, home health agencies (HHAs) have been aware that the effective date for OASIS-E is January 1st, 2023. But what does this really mean for HHAs?  How does this impact patients that were admitted BEFORE January 1st, 2023?  How does this impact patients in which an OASIS assessment was started in 2022, but was not completed until 2023? 

How to Select the Correct Version of OASIS: OASIS-D1 or OASIS-E ? 

CMS has provided additional guidance on exactly when OASIS-E data collection begins, noting that the version of OASIS that should be collected will be based on the M0090 – Date Assessment Completed. The M0090 date is the last date that information used to complete the comprehensive assessment and determine OASIS coding was gathered by the assessing clinician and documentation of the specific responses was completed.

All assessments with a M0090 - Date Assessment Completed on or before December 31, 2022, including the last 5 days of 2022 must be completed with OASIS-D1.  This is true even when the first day of the new certification period is on or after January 1, 2023.

All assessments with a M0090 - Date Assessment Completed on or after January 1, 2023, must be completed with OASIS-E. This is true even when the assessment was initiated in 2022.

OASIS Answers, Inc. has developed the following table to help agencies work through the different scenarios:

Date Assessment is initiated:

M0090 - Date Assessment Completed:

OASIS-D1 or OASIS-E?

Before 1/1/2023

Before 1/1/2023

OASIS-D1

On or after 1/1/2023

OASIS-E

On or after 1/1/2023

On or after 1/1/2023

OASIS-E

Do HHAs Need to Use an Artificial M0090 Date?

In the past, there have been certain situations in which CMS directed agencies to use an artificial M0090 date when transitioning from one version of OASIS to another. However, CMS wants to make it clear that with this transition to OASIS-E, there is no need for the use of artificial M0090 dates.  Want to become an OASIS-E expert?
