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

HB 883 modifies Mississippi's Medicaid rules for managed care providers during credentialing and appeal processes. It allows on-site supervisors at managed care organizations to approve provider work and authorize payment for that work while a provider waits for a final credentialing decision. The bill also prohibits Medicaid from suspending payments during an appeal unless the provider has a prior fraud conviction related to Medicaid. These changes directly affect healthcare providers (like clinics or hospitals) participating in Medicaid managed care programs, ensuring they can receive payment for services rendered during disputes. The policy focuses on maintaining payment continuity during administrative reviews without requiring prior fraud findings.
