CREDENTIALING REQUIREMENTS FOR MS BEHAVIORAL HEALTH PROVIDERS
All MississippiCAN and CHIP providers must be credentialed through the Mississippi Division of Medicaid’s Medicaid Enterprise System Assistance (MESA) provider portal. If you intend to participate for MSCAN/MSCHIP and UBH/Optum commercial and/or Medicare Advantage, you must submit your application through both processes. If you complete the UBH/Optum network participation form, we can include a MSCAN/MSCHIP participation agreement for those networks in addition to commercial and Medicare (if applicable) if your MESA application is completed. If your intent is to include MSCAN/MSCHIP, we recommend that you complete the MESA credentialing first so that we can include a MSCAN/MSCHIP participation agreement. You can access the MESA portal through the Mississippi Medicaid site here.
