As communicated in previous message texts, MassHealth will begin transitioning its Medicaid Management Information System (MMIS) and Provider Online Service Center (POSC) to Amazon Web Services (AWS) to enhance security, scalability, and operational efficiency. The migration has been re-scheduled for the weekend of March 14, 2025.
MassHealth will publish an All Provider Bulletin, MMIS POSC Migration to Amazon Web Services, this month that outlines key cutover information. Please continue to monitor MassHealth communications. All published bulletins can be found on Mass.gov: https://www.mass.gov/lists/400-through-300 and https://www.mass.gov/lists/provider-bulletins-by-year.
Providers, Vendors, and Trading partners are strongly encouraged to refer to the bulletin for additional details. If you do not receive notifications, you can sign up for email alerts at: https://www.mass.gov/masshealth-subscribe-bulletins-TLs.
Please note that leading up to the migration there will be a few adjustments to standard processing timeframes, and during the cutover weekend the application will not be available for use. MassHealth’s migration to AWS will NOT affect MMIS or POSC functionality.
It’s important that services delivered to MassHealth members over the cutover weekend are not disrupted. Please ensure that you continue to provide services to MassHealth members that present a valid MassHealth ID card. If you intend to provide scheduled services over the cutover weekend, please ensure that you validate the MassHealth member’s eligibility on Friday, March 14, before 6:00 pm and again on Monday, March 17, after 7:00 am.
MassHealth will process the financial cycle on Wednesday, March 12, instead of Friday, March 14, so providers should plan accordingly. Providers who normally submit their claims on Thursday or Friday should submit them on Wednesday, March 12, by 3:00 pm instead to be included in the financial cycle for that week. Claims submitted after the financial cycle is run will be included post AWS cutover.
We encourage all providers to stay informed on how these changes may impact your operations.
