Authorization is required if you need to treat a Meridian Medicare-Medicaid member prior to being contracted. Our Medical Management department will review the member’s needs with you and issue an Authorization as needed if a contracted provider is not available to provide the services. Medical Management does coordinate with our contracting department when a non-contracted provider receives an Authorization.

Meridian Medicare-Medicaid Plan (MMP) is a health plan that contracts with both Medicare and Illinois Medicaid to provide benefits of both programs to enrollees. This is not a complete list. The benefit information is a brief summary, not a complete description of benefits. For more information contact the plan or read the Meridian Member Handbook. Out-of-network/non-contracted providers are under no obligation to treat Meridian members, except in emergency situations. Please call our Member Services number or see your Member Handbook for more information, including the cost-sharing that applies to out-of-network services.
