Trading Partner: Frequently Asked Questions

If I already have a Trading Partner number, do I need a new one?

Yes, the old Trading Partner (TP) ID issued by Conduent will not transfer over to the new system called MESA: Medicaid Enterprise System Assistance.

Will my Trading Partner ID work for the provider portal?

No, The TP ID is used for submitting electronic claims to the new MESA system. It is not used to access the MESA Provider Portal. To access the MESA Provider Portal, providers must register for it on or after Oct. 3.

When I enroll as a Trading Partner, do I also have to register for the provider portal?

Typically, only clearinghouses enroll as a Trading Partner to submit electronic transactions (such as an 837 claim.) You are not required to register for the MESA Provider Portal at the time of enrollment as a Trading Partner. However, you will need to register for the MESA Provider Portal to access your remittance advice, verify patient eligibility, and file individual claims on or after Oct. 3.

If we are an out-of-state provider, do we still need to enroll and register as a Trading Partner?

If a provider submits claims through a clearing house or vendor then the provider would not need to enroll for a TP ID; however, the clearing house or vendor would need to enroll for a Trading Partner ID. If you only use the Provider Portal to enter claims, verify eligibility or check your remittance advice, then you would only need to register in the new Provider Portal on or after Oct. 3.

Why do I have need to register again with MS Medicaid, if I am already a MS Medicaid provider?

The new Medicaid system called MESA is going live on Oct. 3. This requires that providers register for the new Provider Portal with the new Medicaid Provider ID that was mailed out in early June. If you did not receive the letter that was mailed in early June, you can retrieve your information at http://dom-azure-app.medicaid.ms.gov/.
