MassHealth MMIS POSC AWS Migration - Claim Submission and Processing Changes
November 4, 2024
As communicated in previous message texts, MassHealth will migrate its Medicaid Management Information System (MMIS) base application and Provider Online Service Center (POSC) to an Amazon Web Services (AWS) data center in early December.
MassHealth is working to mitigate disruption of services, however providers and trading partners should prepare their business operations for some temporary service interruptions. There will be a system outage over the weekend beginning Friday, December 6th through Monday morning December 9th when the system is expected to be restored and fully functional.
If a contingency date is necessary, MassHealth expects to cutover to AWS the following weekend. Please continue to monitor MassHealth communications for additional information regarding the transition.
MassHealth will process the financial cycle that week on Wednesday, December 4th instead of Friday, December 6th. 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.
NOTE: For Nursing Facilities and Rest Homes, the monthly claims cycle will run on Wednesday, December 4th. All monthly claims must be submitted by this date to meet the monthly processing schedule. An additional email blast with more information will be sent to nursing facilities outlining key migration information. Independent Nurses and Doulas will also receive additional tailored communications from MassHealth.
MassHealth PDF Remittance Advices, 835 Remittance and Payment Advice, and payments will follow the normal schedule.
MassHealth will be publishing an All Provider Bulletin prior to the migration. Please be sure 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.
