Home Health Agencies: Information on the Outcome and Assessment Information Set (OASIS)

Find resources and details on the Outcome and Assessment Information Set (OASIS). This information must be collected for adult Medicare and Medicaid patients receiving skilled services. It doesn't apply to patients receiving services for pre- or postnatal conditions.

Note: Patients receiving only personal care, homemaker, and chore services are excluded since those are not skilled services.

Learn about OASIS:

The Division of Quality Assurance (DQA) sponsors a quarterly forum to educate HHAs. Staff can ask questions and stay up to date on OASIS. DQA's OASIS education and automation coordinators jointly host the forum.

Find helpful resources to support submissions, corrections, and account information under OASIS.

OASIS submission

The OASIS data transmission requirement applies to Medicare and Medicaid patients receiving skilled care only. HHAs may continue to collect OASIS data for non-Medicare and non-Medicaid patients for their own use, but they may not submit this data to the state.

The system used by HHAs to submit OASIS data no longer supports the use of test data. Review Federal Register Volume 85, No. 214 (PDF) for more information.

Review these sources to find more information:

OASIS correction policy

The Home Health OASIS Submission/Correction Policy (PDF) fact sheet contains information about policy changes.

Quality Improvement and Evaluation System (QIES) technical support

Find technical guidance such as references and manuals, software tools, and training materials on the QIES Technical Support Office (QTSO) website. See the QTSO HHA Providers page or iQIES Software page for more details.

Patient names and other protected health information (PHI) should only be sent to individuals authorized to receive that information, so care must be taken to ensure the email is addressed correctly. Sending an email containing PHI to an incorrect recipient would be an unauthorized disclosure and a violation of HIPAA. We strongly recommend that you do not include PHI in an email. You may include the resident or assessment identification number.
