Outcome and Assessment Information Set (OASIS)

Subscribe to the OASIS e-newsletter

Home health agencies use the Outcome and Assessment Information Set (OASIS) to conduct thorough and standardized patient evaluations. The automated OASIS system, called the Internet Quality Improvement Evaluation System (iQIES) enables the transmission of data for payment validation under the Home Health Prospective Payment System. Managed by CMS, this federally-owned database adheres to the Federal Privacy Act and the MDS System of Records (MDS-SOR) notice regarding privacy and information disclosure. For more information on CMS’ privacy policy, visit: CMS Privacy Website.

The Quality Improvement and Evaluation Service (QIES) staff plays a vital role in managing and supporting the OASIS health care information to the federal database. Key responsibilities include educating providers on clinical methodologies and the proper completion of OASIS data sets, assisting home health agencies in interpreting validation reports and navigating error corrections, and conducting regular and ad-hoc training sessions for agency staff and surveyors. Further duties involve supporting software vendors and assisting surveyors with assessment-related issues during the survey process. Additionally, we send important announcements and updates via GovDelivery. If you would like to receive updates please sign-up and select the following two topics: OASIS Information and Quality Improvement & Evaluation Service.
