Social Security Disability Insurance (SSDI) is a federal program that pays monthly benefits to people with disabilities who have worked and paid Social Security taxes. Unlike needs-based programs, SSDI is based on your work history and tax contributions—you must have earned enough work credits before your disability began. The program also covers certain family members, including spouses and children of disabled workers. Understanding how SSDI works, who it covers, and how it connects to other programs like Medicare and Medicaid helps you grasp what this benefit actually provides.
These articles explain the fundamentals: how the program defines disability under federal law, what "work credits" are and why they matter, how SSDI differs from Supplemental Security Income (SSI) and other information programs, and what happens to your benefits if you return to work. You'll also learn about the medical and non-medical rules that shape your case, and how SSDI interacts with other income and insurance programs you may have.
