Medicaid; revise certain provisions regarding managed care providers and payments during appeals.

HB 623 updates Mississippi Medicaid procedures for managed care providers during appeals. It allows a provider's direct on-site supervisor (who has begun credentialing and wasn't previously denied) to approve services and authorize payment during a credentialing appeal. It also prohibits the Medicaid Division from suspending payments to a provider during an appeal of a violation finding, unless the provider had a prior fraud conviction. These changes directly affect managed care providers in Mississippi who are appealing credentialing or violation decisions.
