On January 26, 2023, CMS posted the Outcome and Assessment Information Set-OASIS-Error Message User Guide, version 2.0. This 164-page user guide, dated January 18, 2023, addresses Outcome and Assessment Information Set (OASIS) error messages and troubleshooting. My apologies for not posting this earlier!

An OASIS Provider Final Validation Report is automatically generated within 24 hours of successful submission of a file. A file may include one or more records. The Report details the errors, if any, in the submitted records within the file. Go to the Reports section in iQIES to view this report.

Each error is noted on the report by its numeric identifier and severity (Fatal or Warning). The report also includes a brief description of the error and notes the submitted item values that triggered the error.

Notes:

The OASIS Submitter Final Validation Report must be requested by the user who submitted the file.
Records with fatal errors will be rejected. All fatal errors in a record must be corrected and resubmitted.
All warning errors should be reviewed and corrected if appropriate, to ensure the data uploaded is accurate and complete.
Providers who submit files for multiple providers receive one OASIS Agency Final Validation Report for each provider for which records were submitted in a file.
Certain severe fatal errors in the submitted file or one of its records can prevent the system from creating and placing the automatically generated OASIS Agency Final Validation Report in the agency’s folder. To view these errors, the submitter can request the OASIS Submitter Final Validation Report in iQIES.

The Error Messages section lists the error messages in order by Error ID followed by Error Message. The severity and type of error message are shown. A type of error can help determine the solution. The first four explanatory columns are followed by three columns explaining the potential cause, tips to correcting the error, and actions to take.
