Your income must be less than the cost of care in the facility at the Medicaid rate. Medicaid must approve the need for the level of care. You must use some of your income to help pay for the cost of care. This is called the "patient monthly liability." Medicaid will pay the rest to the facility.
Your spouse can keep all of the income he/she receives for himself. He or she may be able to receive some of your income as well.
