Important Documents to Reference:
Starting April 2nd, Administrator users are required to update their facility’s registration information, i.e. Users, Contacts, and Hospital Summary information in the portal. Annual registration updates must be completed between April 2nd and April 30th. Detailed instructions are here.
Note: Failure to complete your updates may result in delays processing files and the release of MHDO’s data to authorized data users.
Additionally, we will be performing our annual Exemption and Profile-level override resets. Due to all Profile and Exemption-Level overrides being reset, most users will have validation issues to review and resolve when submitting Q1 2026 data or Q4 2025 delinquent data. Be sure to see page 3 of the Instructions Manual for helpful information.
Lastly MHDO has implemented improvements in the validations which are listed on page 4 of the Instructions Manual.
See the timeline below listing the important tasks and required dates they must be completed by.
