Final answer:
Medicare supplement insurance policies cannot be used in conjunction with the Medicaid plan.
Step-by-step explanation:
Medicare supplement insurance policies cannot be used in conjunction with the Medicaid plan. Medicare is a federal health insurance program for individuals who are 65 or older, while Medicaid is a joint federal and state program that provides health coverage for low-income individuals. While both programs provide health insurance, they have different eligibility requirements and coverage options. Medicare supplement insurance policies, also known as Medigap policies, are designed to fill the gaps in coverage that are not provided by Medicare, but they cannot be used in conjunction with Medicaid.
