OASIS-E1 to OASIS-E2 Crosswalk Guide
With the OASIS-E2 assessment form scheduled for implementation on April 1, 2026, SHP is pleased to provide home health agencies with a complete side-by-side comparison of the OASIS-E1 and OASIS-E2 assessment forms. Items that have been added or removed between the two OASIS versions are indicated with color coding.
This document includes all items recorded at start of care (SOC), resumption of care (ROC), follow-up (FU), transfer (TRF), discharge (DC), and death at home (DAH). A box next to each item lists the assessment reasons for which the item is recorded.
This guide is an excellent reference for anyone who works with OASIS Assessments and will improve accuracy, help reduce coding errors, and potentially reduce the number of returned claims.
The key changes introduced in OASIS-E2 include:
- Removal of A1250 Transportation (replaced by A1255)
- Addition of A1255 Transportation with revised Yes/No question format
- Removal of O0350 COVID-19 Vaccination from TRF, DC, and DAH time points
- Renumbering of M0069 Gender to A0810 Sex
- Addition of A1110 Language at ROC (previously SOC only)
- Addition of B0200 Hearing at ROC (previously SOC only)
- Addition of B1000 Vision at ROC (previously SOC only)
