For answers to general questions, please review the FAQs below.

  • Group
  • Ordering, Referring, and Prescribing (ORP)
  • Service Facility

I am enrolled as a participating provider in another state’s Medicaid program. Am I also required to enroll in Mississippi’s Medicaid Program to provide services to Medicaid beneficiaries?

Yes, providers must enroll in Mississippi Medicaid to be reimbursed for services rendered to Mississippi Medicaid members.

How do I enroll?

Navigate to the MESA portal and complete an application with the appropriate taxonomy.

How does my registration relate to billing for services?

You must register with the state using the same identifiers you plan to bill with, i.e., TIN/SSN, Specialty, etc.

The following items must be in alignment:

  • Your contract with Envolve / Centene Dental and Vision
  • State Registration
  • Billing Set Up / Configuration

Are there additional requirements and screenings based on risk/risk level?

According to CMS/Medicaid:

Requirements by Risk Level:

  • All Risk Levels:
    • Verify provider meets any applicable Federal regulations or State requirements for the provider type prior to making an enrollment decision.
    • License Verifications.
    • Conduct Database checks.
  • Limited Risks:
    • Site visit.
  • High Risks:
    • Any provider that has a payment suspension based on a credible allegation of fraud within the last 10 years.
    • Any provider excluded within the past 10 years by HHS-OIG or a State Medicaid Agency (SMA).
    • Any provider that has a qualifying Medicaid overpayment.
    • The provider is enrolling within 6 months of the date of the lifting of a temporary moratorium that at the time would have barred the provider’s enrollment.

States may impose additional screening methods “in addition to or more stringent than” those in the regulations. This could result in a change in the risk category assigned for certain types of providers. Providers should check with their SMA to determine their risk category.

Additional requirements based on Provider’s assigned risk level can be found on the “Mississippi Division of Medicaid” site under the Provider Enrollment Forms section.
