The Affordable Care Act of 2010, signed by President Obama on March 23, 2010, creates a national Medicaid minimum eligibility level of 133% of the federal poverty level ($29,700 for a family of four in 2011) for nearly all Americans under age 65. This Medicaid eligibility expansion goes into effect on January 1, 2014 but states can choose to expand coverage with Federal support anytime before this date-see related Federal Policy Guidance and states that have expanded Medicaid prior to 2014. See Eligibility Provisions in the Affordable Care Act.
Other Eligibility Criteria
There are other non-financial eligibility criteria that are used in determining Medicaid eligibility. In order to be eligible for Medicaid, individuals need to satisfy federal and state requirements regarding residency, immigration status, and documentation of U.S. citizenship.
Medicaid coverage may start retroactively for up to 3 months prior to the month of application, if the individual would have been eligible during the retroactive period had he or she applied then. Coverage generally stops at the end of the month in which a person no longer meets the requirements for eligibility.
