Medicaid is a health insurance program for certain low-income people. If you receive Medicaid, this means that the program pays your health care provider for certain health care costs you may accrue. Although Medicaid may cover most of your costs, you may still be required to assist in paying for the medical services by paying a co-pay. Because of the Affordable Care Act, more preventative services are available such as yearly wellness checks.
Each state administers Medicaid through its own state law according to federal law. To qualify to receive Medicaid, you must satisfy certain requirements set forth in both state and federal law. If you are eligible to receive Supplemental Security Income (SSI), you are likely also eligible to receive Medicaid.
