Summary

Mississippi Medicaid has updated their pharmacy prior authorization resource document, clarifying submission procedures and emphasizing that prior auth approval does not guarantee payment. The policy provides detailed instructions for Fee-for-Service and MSCAN beneficiaries, recommending online submission via the MESA portal as the preferred method.

Action Required

Action needed
Immediately: Review current Mississippi Medicaid pharmacy prior authorization procedures. Staff should use the MESA provider portal (https://portal.MS-Medicaid-MESA.com/MS/Provider) for all prior auth requests rather than fax when possible. Ensure both the Standardized One Page Pharmacy Prior Authorization Form and Criteria/Additional Documentation Form are completed for all requests. Verify preferred drug list before submitting PA requests to avoid unnecessary authorizations.
