What is the difference between SSDI and SSI?

SSDI is based on your work history and earnings record [§ 42 U.S.C. 423], while SSI is a needs-based program for people with limited income and resources [§ 42 U.S.C. 1381]. In South Dakota, SSDI leads to Medicare after 24 months, while SSI may provide Medicaid coverage depending on eligibility.

Can I work while receiving SSDI benefits?

Yes. Social Security offers a Trial Work Period where you can work for 9 months and receive full benefits regardless of earnings [§ 20 C.F.R. 404.1592]. After the trial period, benefits continue in months where you earn below the Substantial Gainful Activity limit ($1,550/month in 2024) [§ 20 C.F.R. 404.1574].

How Disability Claims Work

Applying for Social Security Disability benefits is a multi-stage process, and most initial applications are denied. That is not the end — it is built into the system. The appeals process moves from reconsideration to an ALJ hearing, where the majority of approvals actually happen. Understanding each stage helps you prepare the right evidence at the right time, which is the single biggest factor in whether a claim succeeds.
