When a child has a serious medical condition, parents often ask whether Social Security can help. The answer depends on which program you're talking about — because SSDI and SSI work very differently for children, and understanding that difference is the foundation of knowing what kind of legal help makes sense.
SSDI (Social Security Disability Insurance) is an earned benefit tied to a worker's record. Adults qualify based on their own work history. Children, however, cannot qualify for SSDI on their own work record — they haven't worked enough to earn credits.
A child can receive SSDI-related benefits in two specific situations:
For most children with disabilities who need benefits right now, the correct program is usually SSI (Supplemental Security Income) — a needs-based program with no work history requirement.
SSI provides monthly payments to children under 18 who have a qualifying medical condition and whose household meets strict income and asset limits. The SSA evaluates both the child's disability and the financial resources of the parents or guardians living in the home.
Key SSI eligibility factors for children:
| Factor | What SSA Looks At |
|---|---|
| Medical condition | Severity, duration (must last 12+ months or be terminal) |
| Functional limitations | How the condition affects daily activity and development |
| Household income | Parents' income is "deemed" to the child |
| Household assets | Resource limits apply (amounts adjust annually) |
| Age | Different criteria apply under 18 vs. at age 18 redetermination |
The monthly SSI federal benefit rate adjusts each year with cost-of-living adjustments (COLAs). South Carolina does not supplement the federal SSI payment, so Charleston families receive the federal base rate only.
The term "Charleston children's SSDI lawyer" is commonly used even when the actual program involved is SSI — because disability attorneys handle both. What a disability attorney does in a child's case includes:
Whether a claim is filed in Charleston or anywhere else, the process follows the same federal structure:
Most initial applications are denied. That's not an opinion — it's the consistent pattern in SSA data. Denials are not final, and the hearing stage is where detailed medical evidence and legal presentation carry the most weight.
Children approved for SSI face an automatic redetermination when they turn 18. At that point, SSA stops using childhood disability criteria and applies the adult standard — whether the person can perform substantial gainful activity (SGA) in the national economy.
SGA thresholds adjust annually. For 2025, the SGA limit for non-blind individuals is $1,620/month.
This transition catches many families off guard. A child approved years earlier may be denied continuation of benefits at 18 if the medical evidence isn't updated and well-documented. An attorney familiar with Charleston-area cases can help families prepare for this redetermination in advance — ideally before the birthday, not after the denial letter arrives.
No two cases follow the same path. The variables that drive different outcomes include:
The interaction between medical documentation, household finances, and the specific stage of the application process means that outcomes across Charleston families with similar diagnoses can look very different on paper.
Every family's situation brings its own combination of these variables — and that combination is what determines what's actually possible.
