In states that choose to participate, the Medicaid expansion creates a new eligible group: all adults not already eligible. This especially means that adults without dependent children will no longer be excluded from the program. Additionally, the ACA expands the minimum income eligibility threshold to 133 percent FPL (effectively 138 percent FPL) for everyone except the elderly and disabled. This is a floor, not a ceiling: if states already had higher thresholds for certain populations, or want to set higher thresholds, that's fine.
Under the ACA expansion, the definitions shown in the table below will be less relevant than the difference between "traditionally eligible" and "newly eligible" persons.
Those in any population who were already eligible in their state (whether they were already enrolled) can be thought of as "traditionally eligible." They will continue to receive the services to which they are already entitled, and states will continue to receive their standard federal contribution for covering them, whether they enroll before or after 2014.
Those in any population who were not previously eligible but become eligible under ACA (which will include nearly all childless adults, plus many parents and some children depending on states' current thresholds) can be thought of as "newly eligible." Most importantly, states will receive a much higher federal contribution for covering them. Another important distinction: newly eligible enrollees will not necessarily be entitled to standard Medicaid benefits packages. However, states must provide them with "benchmark" or "benchmark equivalent" benefits, which will include the same essential benefits that private plans must include in order to be sold in the new insurance exchanges.

*State threshold must be at or above the U.S. minimum threshold.
**In states that choose to expand Medicaid, the threshold will be at or above the new U.S. minimum threshold starting in 2014. If a state's threshold was already higher, it may remain so.
^AFDC was Aid to Families with Dependent Children, the cash welfare program replaced by TANF (Temporary Assistance to Needy Families) in the 1996 welfare reform bill. SSI is the Supplemental Security Income program that provides cash assistance to low-income disabled, blind and elderly persons.
