Since your mother receives Supplemental Security Income (SSI), she's eligible for Medicaid coverage in her state. In some states, Medicaid will pay most of the cost of residence in certain
assisted living facilities. That's because it's a lower cost alternative for Medicaid than paying for nursing home care. So, if your mother lives in a state where the Medicaid program covers some assisted living facilities, you need to ask the facility she's now living in if it's certified to receive Medicaid coverage. If not, you can find out from the local county social service office where your mother lives, or from your mother's state Medicaid office, what Medicaid-covered assisted living facilities there are in your mother's geographic area, or elsewhere in the state.
