Draft OASIS-E1 Guidance Manual: Overview of Changes

The draft version of the OASIS-E1 Guidance Manual contains the guidance for the new COVID-19 Vaccine item, O0350, and removes guidance related to M0110, M2200, and the GG0130 and GG0170 discharge goals. There have also been changes made to Chapter 1, including adding a placeholder in Section 1.5.1 – Who does OASIS data collection apply to? for language that CMS has noted, “will be updated with the finalization of the HH CY 2025 Final Rule.”

Also included in the draft OASIS-E1 Guidance Manual is the updated Appendix D: Description of Changes from OASIS-E to OASIS-E1 which contains a change table illustrating the changes between the current OASIS-E Manual and the draft OASIS-E1 Manual.
