General Gainwell mailing listing in MESA. Claims, adjustments, enrollment and pharmacy PA have separately designated mailing addresses.

The current Mississippi Medicaid temporary homepage links to the MESA provider portal and publishes this phone. MESA separates provider inquiries from pharmacy, EDI, financial and member contacts. Its provider homepage directs fee-for-service prior-authorization submissions to Telligen. The January 1, 2027 pharmacy-PA fax cutoff is specific to pharmacy PA and does not establish a cutoff for this provider fax.
