In order to ensure your eligibility for Supplemental Security Income (SSI) or Social Security Disability Insurance (SSDI), you should review some of the major disqualifiers before beginning the application process. Eligible individuals can benefit from both programs though they have distinct differences. The major difference is SSI eligibility qualification relies on age, disability, and limited resources and income, while SSDI eligibility determination relies on disability and work credits. In most states, SSI recipients automatically qualify for Medicaid health care coverage, which could result in additional supplementary benefits through your state’s Medicaid program. However, both programs have some common reasons that can disqualify your claim.
