Effective January 1, 2014, MAGI eligibility rules will be used to determine eligibility for nonelderly, nondisabled eligibility groups. The transition to MAGI also involves converting current net income eligibility standards to MAGI standards. MAGI rules apply regardless of whether a state adopts the new adult eligibility group. The December 28, 2012 Modified Adjusted Gross Income (MAGI) conversion guidance (PDF, 177.59 KB) sets out options for a state to use a standardized MAGI conversion methodology (using Survey of Income and Program Participation (SIPP) data or with state data) or to propose an alternative methodology for converting to MAGI.
There are two potential ways of using the standardized MAGI conversion methodology:
- States may choose to have CMS calculate the converted income levels for eligibility groups requiring conversion using state-adjusted data from the Census Bureau's SIPP; or
- States may choose to use their own data as the source for applying the standardized conversion methodology.
For each eligibility group income level that needs to be converted, under the standardized MAGI conversion methodology, individuals whose net income is within 25 percentage points of the FPL below the current income standards will be selected (for example, if the current standard is 80 percent of the FPL, the analysis will include people with incomes between 55 and 80 percent FPL). The next step is to calculate disregards as a percent of FPL for each selected individual. The resulting average disregard amount as a percent of FPL is added to the current net income standard to get the converted standard.
For example, if the average disregard is 8 percent FPL, the converted standard would be 88 percent FPL. This basic process is the same regardless of whether SIPP data or state data is used.
Alternatively, states have the option to propose their own method, subject to approval by CMS. States are asked to provide a statement of intent by February 15, 2013 and must submit their MAGI conversion plans by April 30.
