Which service refers to Medicaid services provided via private insurance plans?

Medicaid managed care is the correct answer because it encompasses a system in which Medicaid services are delivered through private insurance plans. In this model, states contract with private managed care organizations to provide Medicaid benefits to beneficiaries. These organizations are responsible for coordinating care and managing costs, which can lead to improved efficiencies and better health outcomes for enrollees.

This approach includes a range of services aligned with the Medicaid program but is distinct due to its emphasis on managed care principles, such as wellness initiatives, preventive care, and the use of networks of providers. By working with private insurance companies, Medicaid managed care can facilitate easier access to services, quality improvements, and effective care management for recipients, all while navigating the complexities of Medicaid regulations.

Other options do not represent the delivering of Medicaid services through private insurance. Medicaid expansion refers to the initiative that allows states to expand their Medicaid programs under the Affordable Care Act, while Medicaid fee-for-service is a traditional payment model where providers are paid for each service rendered without a managed care entity overseeing the process. Medicaid supplemental coverage typically refers to additional coverage that helps fill gaps in standard Medicaid benefits rather than relating to how services are provided through private plans.
