OASIS software for home health: 2026 buyer's guide

OASIS (Outcome and Assessment Information Set) is the standardized assessment instrument CMS requires Medicare-certified home health agencies to submit. The current version is OASIS-E, effective January 2023, which added Social Determinants of Health items. CMS continues to revise the instrument as part of HHVBP refinement; vendors should ship form updates within 30 days of CMS publication.

OASIS is required at five trigger points for Medicare-certified home health agencies: (1) Start of Care (SOC), (2) Resumption of Care (ROC) after a hospitalization, (3) Recertification (every 60 days), (4) Transfer to inpatient facility, (5) Discharge from agency.

iQIES (Internet Quality Improvement and Evaluation System) is the CMS portal where Medicare-certified providers submit OASIS, MDS (skilled nursing), and IRF-PAI (inpatient rehab) data. OASIS software typically pushes assessments to iQIES via API or generates the export file for manual upload. Live API submission is faster, fewer errors, and is the modern standard.

Yes. AveeCare includes OASIS-E2 and OASIS-E1 assessments at every timepoint, with the CMS edits checked before an assessment is completed and before export. It builds iQIES-ready batch files that your agency uploads to iQIES under its own login (AveeCare does not submit to iQIES for you), and imports the iQIES Final Validation Report to show which assessments were accepted. An agency can sign up for OASIS submission only, at the same $6 per active patient per month as the rest of AveeCare.
