On December 20, 2018 CMS released the FINAL Guidance Manual for OASIS-D 12 days before the implementation of assessment instrument.
In July of 2018 an errata for the manual was released. Historically CMS has released an errata after the final manual.
The final OASIS-D Guidance Manual contained only 4 of the 17 identified errors. CMS is directing agencies to follow the errata, which supersedes the Final manual, until CMS releases the next version.
