OASIS-E1: What Home Health Agencies Need to Know

OASIS E1 What HH Agencies Need to Know

The OASIS instrument has undergone significant revisions over the years to increase standardization across post-acute care settings, as mandated by the Improving Medicare Post-Acute Care Transformation (IMPACT) Act of 2014. The transition from OASIS-D1 to OASIS-E in 2023 brought some of the most expansive changes to date, aimed at uniformly collecting health data and enabling cross-setting quality measure calculations.

As home health agencies (HHAs) continue to adapt to OASIS-E, the Centers for Medicare & Medicaid Services (CMS) is already preparing for the next iteration – OASIS-E1, effective January 1, 2025. While not as sweeping as last year’s overhaul, OASIS-E1 will incorporate important updates driven by changes to the Home Health Quality Reporting Program (HHQRP).

Contact us today to request an OASIS-E1 readiness assessment. With our guidance, you can confidently adapt to the latest regulatory changes while delivering the highest quality patient care.

HHQRP Measure Changes Impacting OASIS-E1

In the Calendar Year 2024 Home Health Prospective Payment System Final Rule, CMS finalized several HHQRP measure changes that necessitate revisions to the OASIS:

Measures Being Removed

  • Application of Functional Assessment/Care Plan Measure: Due to high and unvarying performance, this cross-setting process measure will be removed from the CY 2025 HHQRP. As a result, HHAs will no longer need to report Self-Care Discharge Goals (GG0130, Column 2) or Mobility Discharge Goals (GG0170, Column 2) on OASIS.
  • M0110 – Episode Timing and M2200 – Therapy Needs: These long-standing OASIS items are being removed as they are no longer used for quality measure calculations or payment determination under the Patient-Driven Groupings Model (PDGM).

New Measures Being Added

  • Discharge Function Score Measure: This cross-setting outcome measure will replace the Application of Functional Assessment/Care Plan Measure in the CY 2025 HHQRP. It evaluates functional status based on existing GG self-care and mobility items, requiring no additional data collection from HHAs.
  • Patient/Resident COVID-19 Vaccine Measure: A new cross-setting measure reporting the percentage of patients up to date on COVID-19 vaccinations per CDC guidance. HHAs will need to collect and report this data on OASIS beginning January 1, 2025.

OASIS-E1 Item Changes

To align with the HHQRP updates, CMS has released a draft OASIS-E1 instrument with the following changes:

Items Being Removed

  • M0110 – Episode Timing  
  • M2200 – Therapy Needs
  • GG0130 Self-Care Discharge Goals (Column 2)
  • GG0170 Mobility Discharge Goals (Column 2)

Items Being Added

  • O0350A – Patient’s COVID-19 Vaccination Status (Up to Date: Y/N)

Additional Changes

  • M2420 (Discharge Disposition) responses updated to replace “formal assistive services” with “skilled services from a Medicare Certified HHA”
  • D0150 (Patient Mood Interview) instructions clarified on when to stop/continue the interview

While less extensive than OASIS-E, these OASIS-E1 changes underscore the importance of staying up to date on evolving requirements. Accurate OASIS data remains critical for PDGM reimbursement and publicly reported quality outcomes.

As the January 1, 2025 implementation date approaches, HHAs should closely monitor CMS guidance and prepare their staff accordingly. HealthRev Partners will continue providing updates and expert guidance to ensure our clients are ready for a smooth transition to OASIS-E1.
