CMS Responds to LeadingAge, Updates All Payer OASIS Requirements FAQ

In response to many outstanding questions from LeadingAge in our comment letter on the CY2025 Home Health Proposed Rule, the Centers for Medicare and Medicaid Services (CMS) has updated OASIS E-1 Q&As.

As of July 1, 2025 all home health agencies will be required to submit OASIS data on all patients regardless of payer source. CMS will allow agencies to start voluntarily submitting all-payer OASIS data on January 1, 2025. In this document CMS outlines how they intend to use this data, clarification on the requirements for OASIS privacy notice, the patients which are excluded from collection, how collection will impact Medicaid only patients and charity patients.
