The transition to OASIS-E is upon all Medicare certified home health agencies.  In the January 2022 CMS OASIS Q&As (category 2, Q/A 1), clarification was  the OASIS item, M0090, establishes whether OASIS-D1 or OASIS-E will be the required data set.  As a reminder, the M0090 item is the last date information is used to complete the comprehensive assessment.  Each OASIS RFA (reason for assessment) has a maximum allowance of time to complete the comprehensive assessment.  Home health agencies should also have a policy regarding the agency’s allowed time permitted for assessment completion.  Recertification OASIS (RFA 4) may present the greatest problem for starts of episode of January 2nd through 5th.   Due to the 5-day window for assessment completion (days 56-60 of the previous episode), M0090 could conceivably fall during December 2022 (OASIS-D1 data set) or January 2023 (OASIS-E data set). Other RFAs with 2- or 5-day assessment completion allowances may also tricky for agencies.  The bottom line?  Make sure your assessing clinicians and quality assurance staff understand the impact of M0090 on OASIS-E.
