Beginning June 29, 2025, MMIS will implement updates to the Provider Online Service Center (POSC) homepage, enhancing its visual design and overall functionality. These enhancements will affect both the pre-login and post-login interfaces and will include a revised message for unauthorized service access attempts.
The redesigned pre-login page will display banner alerts at the top, reposition the ‘Login’ button for greater visibility, and introduce a ‘View Broadcast Messages’ button. Additionally, it will provide a clearly listed set of available pre-login services.
The new post-login page will feature an updated Left Navigation menu, accessible immediately after login. A ‘View Broadcast Messages’ button will be introduced, and all services previously available on the pre-login page will remain accessible on the post-login screen.
The Unauthorized Access Page is displayed when a POSC user attempts to access a Left Navigation function without the necessary permissions. With the POSC refresh, this page will be enhanced to include an image for improved clarity and will offer troubleshooting guidance. The pre-login services will also remain accessible from this page.
The POSC URL (https://mmis-portal.ehs.state.ma.us/EHSProviderPortal) will not be changing as part of this refresh. Users can continue to use the system as usual and there is no change to their login credentials.
