OASIS-E2

Three item-level changes define the release. First, the legacy patient-tracking item M0069 (Gender) was retired in favor of A0810 (Sex), a standardized item consistent with other CMS post-acute care instruments. Second, A1250, the transportation item introduced with OASIS-E's social determinants of health content, was replaced by a revised transportation item, A1255. Third, O0350, the COVID-19 vaccination status item added in OASIS-E1, was removed entirely. Everything else, including Section GG, the mood and cognition interviews, and the M-item core, carried forward.

Version applicability follows the assessment date, not the start of care date. An episode that began under OASIS-E1 in early 2026 simply switches versions at its next assessment time point on or after April 1, 2026. Software vendors handle the form change, but agencies own the compliance risk: an assessment completed on or after the effective date must be collected and submitted under E2 specifications through iQIES, and QA reviewers should confirm the correct item set is in use during the transition weeks.

The changes look cosmetic but follow a consistent policy thread: convergence of assessment items across home health, skilled nursing, inpatient rehabilitation, and long-term care hospital settings. Standardized A-section items like A0810 and A1255 let CMS compare patients and outcomes across post-acute care, support cross-setting quality measures, and simplify data specifications in iQIES. For agencies, each swap is small, but the cumulative direction matters: OASIS is steadily becoming the home health slice of a shared post-acute assessment language rather than a standalone instrument.

Version changes fail at the margins, usually on assessments opened before the cutover and completed after it. To stay clean:

• Update templates, cheat sheets, and QA checklists before the effective date
• Train clinicians on the changed items, including intent and response coding for A0810 and A1255
• Watch in-flight assessments that straddle April 1, 2026 and confirm the right version applies
• Verify your first E2 submission batches are accepted in iQIES without fatal errors
