Settlements and Medicaid/SSI: The Special Needs Trust

A settlement is supposed to be the resolution. For someone receiving Medicaid or SSI, it can just as easily be the event that ends both — not because anyone did anything wrong, but because an ordinary settlement check is exactly the kind of asset these programs are designed to count against you. The fix is well established and works reliably. It only works if it happens before the money arrives.

Quick answer: SSDI and Medicare are not means-tested — a settlement of any size leaves them untouched. SSI and Medicaid generally are, with an asset limit as low as $2,000 for an individual, and an unprotected settlement can terminate both. The standard fix is a first-party special needs trust under 42 U.S.C. § 1396p(d)(4)(A), which holds the settlement for the beneficiary’s supplemental needs without it counting as a resource — in exchange for reimbursing Medicaid from what remains at death. Get this in place before the settlement is disbursed, not after.

Four Programs, Two Completely Different Rules

The confusion here is almost always caused by similar-sounding names hiding an opposite rule:

Program	Means-tested?	Effect of a settlement
SSDI (Social Security Disability Insurance)	No — earned benefit based on work credits	None. Assets and unearned income don’t affect it.
Medicare	No — based on age or disability status	None. Not income- or asset-based.
SSI (Supplemental Security Income)	Yes — asset limit as low as $2,000 for an individual	A settlement above the limit terminates benefits until spent down or protected.
Medicaid	Yes, in most states — often tied directly to SSI eligibility	Losing SSI frequently means losing Medicaid at the same time.

SSDI and SSI are not the same program, despite the similar name, and this is the single most consequential mix-up in this entire area. A claimant can safely receive a large settlement while on SSDI and Medicare. The identical settlement, received by someone on SSI and Medicaid, can end both.

The Special Needs Trust

A special needs trust (also called a supplemental needs trust) holds settlement funds for the beneficiary’s supplemental needs — items and services beyond what Medicaid or SSI already cover — without those funds counting as the beneficiary’s own resource.

The first-party (self-settled) version, governed by 42 U.S.C. § 1396p(d)(4)(A), is what applies here, since it’s funded with the disabled person’s own settlement money:

• The beneficiary must meet the federal disability definition and be under 65 when the trust is established and funded
• The trust must be irrevocable
• Upon the beneficiary’s death, the trust must reimburse Medicaid for benefits paid during their lifetime, up to the amount remaining in the trust — this is the tradeoff for the protection, not a penalty
• Distributions are generally limited to supplemental needs — items and services Medicaid and SSI don’t already provide, rather than basic food or shelter, which can itself affect SSI in a different way if handled incorrectly

Who can establish one changed in 2016. For years, a mentally competent adult with disabilities could not set up their own special needs trust — only a parent, grandparent, legal guardian, or a court could do it, a genuinely strange gap that forced competent people to seek unnecessary court involvement. The Special Needs Trust Fairness Act, part of the 21st Century Cures Act signed December 13, 2016, fixed this by letting the individual establish their own trust directly.

Pooled trusts, under a related provision, are managed by a nonprofit organization on behalf of many beneficiaries, each with a separate account — an alternative worth asking about, particularly for a smaller settlement where an individually administered trust’s costs are harder to justify.

ABLE Accounts: The Simpler Tool for Smaller Amounts

An ABLE account, created under 26 U.S.C. § 529A, is a tax-advantaged savings account for a person whose disability began before a set age. Funds in it, up to a set balance, are not counted as a resource for SSI or Medicaid.

It’s far simpler and cheaper to open than a trust — closer to a bank account than a legal instrument — but annual contribution limits make it poorly suited as the sole vehicle for a large settlement. It works well alongside a special needs trust: the trust holds the bulk of the recovery, while an ABLE account holds a smaller, more liquid, more flexible amount for everyday supplemental spending.

Why a Structured Settlement Isn’t a Shortcut

It’s tempting to assume that simply structuring the settlement as periodic payments avoids the lump-sum problem. It doesn’t, on its own: periodic payments are still generally counted as income in the month received for SSI purposes, which can push a recipient over the income limit every single month the payment arrives, even though no large lump sum ever appears.

The two tools are normally used together, not as alternatives: a structure directs its payments into the special needs trust, which then manages distributions in a way that doesn’t count against the beneficiary. See our guide to lump sum vs. structured settlements for how the underlying structure itself works.

A Related but Different Problem: Medicare Set-Asides

Do not confuse this with a Medicare Set-Aside (MSA), which is a different mechanism solving a different problem. An MSA allocates part of a workers’ compensation settlement to cover future injury-related medical care, protecting Medicare’s position as a secondary payer — relevant because Medicare is not means-tested and this isn’t about preserving eligibility, it’s about which payer covers future treatment. See our guide to medical liens and subrogation for how Medicare’s reimbursement rights generally work.

Practical Steps

1. Identify exactly which programs are actually received — SSDI and SSI are not interchangeable, and neither are Medicare and Medicaid.
2. Raise this with your attorney before the settlement is finalized. Once funds are disbursed directly to the beneficiary, the eligibility damage can already be done.
3. Establish the special needs trust — or confirm the pooled trust option — before the money moves, not afterward.
4. Consider an ABLE account for smaller amounts or as a companion to the trust.
5. Coordinate the trust with any structured settlement so periodic payments flow into the trust rather than to the beneficiary directly.
6. Get advice from someone who does both — settlement planning and public-benefits law are different specialties, and this area sits squarely between them.
