OASIS iQIES Software Discontinuation

Feb 24, 2026

As part of our ongoing efforts to modernize and streamline data submission and assessment management, The Centers for Medicare & Medicaid Services (CMS) is officially discontinuing the legacy Internet Quality Improvement and Evaluation System (iQIES) front-end user interface (data entry software for manually creating assessments) effective April 1, 2026. Home Health Agencies (HHA’s) will not be able to use this software to directly input assessment data for OASIS assessments with target dates on or after 4/1/2026. Prior assessments (dated 1/1/2025 – 3/31/2026) will be accepted until 12/31/2026. Future data will need to be uploaded in the correct format. For additional information and questions visit the Home Health Data Specifications page.
