CMS Releases OASIS E-2 Guidance Manual

OASIS E-2 is going into effect as of April 1, 2026.

Here is a summary of the key changes from OASIS E-1 to OASIS E-2:

Major Item Changes

1. Transportation item revised

·        OASIS E-1: Collected A1250 – Transportation, which asked about lack of reliable transportation and how that affected medical appointments/needs.

·        OASIS E-2: A1250 is removed and replaced by a new A1255 – Transportation item to better align with similar items in other CMS post-acute care tools.

2. Gender/Sex item updated

·        OASIS E-1: Uses M0069 – Gender.

·        OASIS E-2: Replaced by A0810 – Sex (reflects standardized terminology used across CMS instruments).

3. COVID-19 item removed

·        OASIS E-1: Included O0350 – Patient’s COVID-19 vaccination is up to date (added in E-1 to support the COVID-19 vaccination quality measure).

·        OASIS E-2: O0350 is being removed (the measure or data collection requirement is no longer part of the OASIS data set in E-2).

Additional Timepoint & Item Scope Adjustments

1.      New or expanded items at Resumption of Care (ROC)

OASIS E-2 adds A1110 – Language, B0200 – Hearing, and B1000 – Vision to the list of items collected at the ROC time point (previously these may not have been required at ROC).

Skip Patterns and Minor Edits

Some skip patterns and edit logic are modified (e.g., how responses flow between items) due to these item changes.
