Utah Medicaid is in the process of replacing MMIS and MMCS with a new system called PRISM, which will go-live on April 3, 2023.  In preparation, the Medicaid systems will “freeze” operations from March 13 through April 2, 2023. The system freeze will impact provider enrollment, claims processing and payments, medical prior authorizations, and pharmacy prior authorizations for pharmacy-related HCPCS codes.

PRISM Project Go-Live


Utah Medicaid is in the process of replacing the Utah Medicaid Management Information System (MMIS) with a new system called Provider Reimbursement Information System for Medicaid (PRISM). The Provider Enrollment component of PRISM was implemented in 2016 and updated in June 2020. The remaining components were previously scheduled to go live on January 3, 2023. After a soft go-live in January, PRISM will be fully operational and go-live on April 3, 2023 with the following components:

  • Managed Care Processes
  • Prior Authorization
  • Member Eligibility
  • Claims Adjudication
  • Claims Payments
  • Member Web Portal
  • Audit Studio (Fraud and Abuse System)

System Freeze

To support the conversion of data from the current MMIS and MMCS systems to the PRISM system, a “freeze” of system functions will occur. This is a standard process for system conversions that will impact operations. The Medicaid systems will “freeze” operations from March 13 through April 2, 2023. For more information, please refer to the Utah Medicaid System Freeze FAQ.

Claims Submission

With the new PRISM system, paper claims will no longer be accepted. The last day to submit paper claims will be February 22, 2023. Paper claims received on or after February 23, 2023, will be securely destroyed and no longer returned to providers or their vendors.

Additionally, providers can submit electronic claim inquiries (276/277 and 837) until March 8, 2023 at 5:00 p.m. MST. Any electronic claim inquiries submitted after that date/time will be processed after the freeze period ends.
