Throughline explains what your letters and documents say, surfaces the dates on them, and points you to the office that handles each step. It does not give legal, benefits, or tax advice, and it never decides what you or your family member qualify for.
What this is
When a child who received SSI turns 18, Social Security re-decides whether they still qualify using the adult disability rules, which are different from the rules for children. Being asked to prove eligibility all over again can feel alarming — but this review is routine, expected, and something you can take part in.
What it means
This is one of the most stressful letters families receive, and it catches many by surprise. It is a scheduled review under the adult rules, not an automatic cutoff — but because the adult standard is different and stricter, the outcome can go either way, and benefits can change or end. That's exactly why taking part fully matters: returning the requested information by the date on the letter, getting free help from a Parent Center or benefits planner, and appealing a decision you disagree with are the most useful things you can do.
What it asks of you
It creates a few steps to handle. From this document we were able to read: Who the review is about, Claim / record number, Date of the notice, Date to return information by. The checklist below lists each step and the office that handles it.

What to do next
Understand what the age-18 review is
Around the time a child who got SSI turns 18, Social Security reviews their eligibility under the adult disability rules. It is a normal step, not a penalty — but the adult rules are stricter, so taking part fully matters.

Return the requested information by the date on the letter
The review asks for forms and information, often including medical records and details about daily living, school, and work. Sending it back by the date requested keeps the process moving and protects benefits.

A family support & advocacy organization
Free help understanding benefits, IEPs, and the system — from your state's federally funded Parent Training and Information (PTI) center and local groups like The Arc. A good place to bring a hard letter and ask 'what does this mean for us?'

If benefits are stopped, you can appeal — and ask to keep them meanwhile
If the decision ends benefits, you can appeal. Acting quickly matters: appealing within a short window can let payments continue while the appeal is decided.
Timing
If the decision stops benefits, you generally have a set number of days to appeal — and acting within about 10 days can keep payments going during the appeal.

Throughline is a tool you and your family control for understanding the benefits, school, and legal paperwork that come with supporting someone with a disability. It is not a law firm, a benefits-planning service, or a financial advisor, and using it does not create any professional relationship. Amounts, limits, and deadlines change every year and vary by state — always confirm each step with the office named on it before you act.
We do not determine eligibility. Only the Social Security Administration, your state Medicaid agency, or the school district can decide what someone qualifies for or receives — we will never tell you that you do or do not qualify.
We do not give legal advice. Guardianship, supported decision-making, and special-needs trusts are legal matters that turn on your state's law and your family's situation. When a step is legal in nature, we point you to the court and to attorneys who do this work.
Some moves can affect benefits in ways that are hard to undo — a gift, an inheritance, the wrong kind of savings account, or income over a limit can reduce or pause SSI or Medicaid. Before making a financial or legal change, confirm with the agency or a benefits or special-needs planning professional first.
Benefit figures (SSI and SSDI amounts, resource limits, ABLE limits, Medicaid income standards) are set federally or by your state, change yearly, and are shown here with an "as of" date from a public source. Treat every figure and date as a prompt to verify with the office, not as the final word.
