MASSHEALTH'S MMIS/POSC MIGRATION TO AMAZON WEB SERVICES IS COMPLETE

MassHealth completed the Medicaid Management Information System (MMIS) and Provider Online Service Center (POSC) to Amazon Web Services (AWS), on Monday, March 17, 2025. MassHealth published All Provider Bulletin 401: MMIS POSC Migration to Amazon Web Services, which outlines key cutover information. All Provider Bulletin 401 can be found on Mass.gov: 2025 MassHealth provider bulletins. 

If Providers, Vendors, and Trading Partners have issues accessing MMIS or the POSC you are strongly encouraged to review the bulletin, ensure that you have implemented the appropriate changes, and troubleshoot your issues before seeking assistance from your respective call center.

Specifically:

1. Ensure that you are using the correct POSC URL. Clear your browser cache, cookies, and all previous POSC bookmarks before trying to access the new POSC URL.
2. Check in with your technical team and ensure that they have “safe listed” the two new MassHealth AWS IP addresses so that your organization can access the POSC in the cloud.
3. If you have completed these steps and your organization still cannot access MMIS or the POSC, please capture screen shots and other relevant information that can be used to articulate your access issue to MassHealth.

Reminder: Leading up to the migration there were a few adjustments to standard processing timeframes. Once MMIS and the POSC are restored you will be able to continue using the system as usual. Claims submitted after Wednesday, March 12 at 3:00 pm will be included in the financial cycle for the week ending March 21, 2025.

AWS CUTOVER ELIGIBILITY VERIFICATION

Reminder: MassHealth providers were instructed to check eligibility for MassHealth members that were scheduled to receive services during the AWS cutover weekend before and after the cutover. Providers were also notified to provide services to members that present a valid MassHealth or Managed Care Entity (MCE) ID card during the cutover weekend (March 14 - March 17, 2025). If you provided services to a MassHealth member between 12:00 pm, March 14, 2025, through 6:59 am, March 17, 2025, and then found that the member was not eligible, or your claim was rejected, you may request a MassHealth review if you complied with MassHealth's instructions:

• You checked eligibility before and after the cutover weekend and found that the member's eligibility status changed.
• You provided service to a member that presented a valid MassHealth or MCE ID that weekend and could not check eligibility during the cutover weekend, that you later found was not eligible.

If you meet this criterion, you may submit a request to MassHealth to review your issue by completing the following within 90 days from the Date of Service:

• Submit the claim on the POSC via Direct Data Entry. Use Delay Reason Code 3.
• Upload a letter stating the issue and applicable criterion noted above. Please include any additional information deemed necessary to demonstrate your issue or justify your request.
• Include a copy of the MassHealth or MCE ID card presented at the time of service where applicable. If an ID card was not presented for an urgent care service, provide a copy of the registration/transfer sheet or any other supporting documentation.

Upon receipt, MassHealth will evaluate your request and provide a response and the disposition of your request.

Please note: Managed Care Entity (MCE) providers must contact the appropriate MCE to address health plan member eligibility issues.

IMPORTANT UPDATE: MASSHEALTH MMIS/POSC MIGRATION TO AMAZON WEB SERVICE 3/14/2025 - 3/17/2025

MassHealth will begin migrating its Medicaid Management Information System (MMIS) and Provider Online Service Center (POSC) to Amazon Web Services (AWS) the weekend of March 14, 2025. MassHealth has published All Provider Bulletin 401: MMIS POSC Migration to Amazon Web Services, which outlines key cutover information, related shut down of functionality, and a list of activities that will take place leading up to and through cutover. Providers, Vendors, and Trading Partners are strongly encouraged to review the bulletin for additional details including new URL, IP Addresses, and other technical information to ensure your organization is ready for the cutover and the transition is smooth.

All published bulletins can be found on Mass.gov: 401 through 300 and Provider bulletins by year.

Please note that MMIS and the POSC will not be available for use from Friday, March 14 at 12:00 pm through Monday, March 17 at 7:00 am. MassHealth’s migration to AWS will NOT affect the look and functionality of the MMIS or POSC application.

REMINDER: 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.

REMINDER: 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 the POSC shuts down at 12:00 pm and again on Monday, March 17 after 7:00 am. Please note, providers may contact MassHealth Customer Service up until 6:00 pm on Friday, March 14 to validate eligibility verification as necessary.
