OASIS Data Specifications Version 1.40 / SQLGOLD 205
Reduced OASIS Collection at Recertification/Follow-up
The OASIS data set used at Reason for Assessment (RFA)4 and RFA 5, i.e., follow-up and other follow-up, has been substantially reduced. For RFA 4 or 5 assessment conducted on or after December 16, 2002, HHAs will be required to collect only those 23 items currently used to generate a payment group for a patientís subsequent episode of care plus the discipline of the person completing the assessment (M0080) and the date the assessment was completed (M0090).
