Pekas Smith, an Arizona disability law firm, has released a detailed comparison of Social Security Disability Insurance (SSDI) and Supplemental Security Income (SSI) to help claimants understand how their choice of program affects access to Medicare and AHCCCS, Arizona's Medicaid program. The distinction is critical because each program follows different eligibility rules and provides different health coverage.
SSDI is an insurance program funded through payroll taxes. Eligibility requires sufficient work credits, typically 40 credits with 20 earned in the last 10 years. Benefit amounts are based on lifetime earnings and are not reduced by other income or assets. Once approved, SSDI recipients become eligible for Medicare after a 24-month waiting period. In contrast, SSI is a needs-based program funded by general tax revenues. Eligibility depends on strict income and resource limits—$2,000 for individuals and $3,000 for couples. SSI recipients in Arizona are typically eligible for AHCCCS coverage immediately, with no waiting period.
Some individuals qualify for both programs, known as concurrent benefits, when their SSDI payment is below the SSI income threshold. The Social Security Administration evaluates both through a single application, but the medical and non-medical criteria are assessed separately. Jeremy D. Pekas, founding partner at Pekas Smith, noted, "Applicants sometimes apply for the wrong program, or assume they only qualify for one when they qualify for both. The distinction matters at the application stage because the documentation requirements differ."
Both programs use the same medical definition of disability and the SSA's five-step sequential evaluation process. The primary differences are non-medical: SSDI is an earned benefit based on work history, while SSI is means-tested based on current financial need. For more details, the firm provides a breakdown of Supplemental Security Income in Arizona, including resource limits and AHCCCS coverage, as well as SSDI work credit requirements and Arizona eligibility rules on their website.
Understanding these differences can prevent application errors and delays. Pekas Smith, founded by Jeremy D. Pekas and Tye Smith, represents claimants in SSDI, SSI, and disability appeals matters at every stage of the SSA process.
