Updated: MassHealth MMIS POSC AWS Migration – Claim Submission and Processing Changes

MassHealth will migrate its Medicaid Management Information System (MMIS) and Provider Online Service Center (POSC) to an Amazon Web Services (AWS) data center Friday afternoon 12/6/2024 through Monday morning 12/9/2024. The migration to the AWS cloud will provide MassHealth with greater security, scalability, and will enable the agency to implement hardware/software technology refreshes without major disruptions to the MMIS POSC availability.

MassHealth will publish an All Provider Bulletin within the next week that outlines key cutover information. Please monitor MassHealth communications. 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 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 services over the cutover weekend, please ensure that you validate the MassHealth member’s eligibility on Friday, December 6th and again on Monday, December 9th.

MassHealth will process the financial cycle on Wednesday, December 4th instead of Friday, December 6th so providers should plan accordingly. Providers who normally submit their claims on Thursday or Friday should submit them on Wednesday, December 4th by 3:00 pm instead to be included in the financial cycle for that week. Claims submitted after 3:00 pm on Wednesday, December 4th will be included in the following week’s financial cycle. Claims submitted after the financial cycle is run will be included post cutover AWS weekly cycle the following week.

Refer to previous banner messages for important technical changes and provider training opportunities.

NOTE: If a contingency date is necessary, MassHealth expects to cut over to AWS the following weekend. Please continue to monitor MassHealth communications for additional information regarding the transition.

MassHealth will continue to communicate with all providers regarding the AWS migration through standard broadcast and banner messages, email blasts and information sessions. Please continue to monitor all MassHealth communications regarding the AWS migration. If you have any questions regarding this AWS migration notification, please contact MassHealth:
