What are the three types of SSI?

The three types of Supplemental Security Income (SSI) are identified by specific legal references within the Social Security Act. The correct options, 1611, 1619(a), and 1619(b), refer to the following:

• 1611 outlines the general eligibility criteria for SSI payments based on financial need and disability.
• 1619(a) provides provisions that allow recipients to maintain their eligibility for SSI while earning income, as long as their earnings are below certain thresholds.
• 1619(b) extends Medicaid eligibility for certain individuals who are working and earning above the SSI limits, ensuring they do not lose healthcare benefits when they begin to earn more from employment.

This combination of provisions emphasizes both the support for individuals with disabilities in terms of financial assistance and the encouragement of work without the fear of losing essential healthcare benefits. The other options contain incorrect references or do not match the established types of SSI, which is why they do not present the complete and accurate framework that is represented in the correct answer.
