Mississippi DAC Medicaid Protection

The Problem DAC Creates for Medicaid

Disabled Adult Child (DAC) benefits are a Title II Social Security benefit that allows an adult whose disability began before age 22 to draw monthly cash payments on a parent's work record when that parent retires, becomes disabled, or dies. For many Mississippi families, DAC represents a significant income increase—the monthly payment is based on the parent's earnings history and can substantially exceed the SSI Federal Benefit Rate of $994 per month in 2026.

That increase creates a problem. SSI is means-tested with strict income limits. When DAC benefits begin flowing, the combined income typically pushes the individual over the SSI eligibility threshold, and SSI cash payments stop. In Mississippi's Section 1634 system, where SSI and Medicaid are directly linked, losing SSI should logically mean losing Medicaid.

For an adult with intellectual or developmental disabilities who depends on Medicaid for therapy, prescription medications, personal care attendants, and ID/DD Waiver-funded services, losing health coverage would be catastrophic. That is where Protected DAC rules intervene.

How Protected DAC Works

Federal law requires states to provide continued Medicaid coverage to individuals who lose SSI solely because they began receiving DAC benefits (or because their existing DAC benefits increased). This protection applies automatically in Mississippi through the Division of Medicaid.

The mechanics work like this:

1. The individual is receiving SSI and, through Mississippi's Section 1634 agreement, automatically enrolled in Medicaid.
2. A parent retires, becomes disabled, or dies, triggering DAC benefit eligibility.
3. The SSA begins paying DAC benefits on the parent's record.
4. The DAC payment exceeds what the individual would receive under SSI, so SSI cash payments are reduced to zero.
5. Despite losing SSI cash, the individual retains full Mississippi Medicaid coverage under the "Disabled Adult Children" coverage group, provided they meet all other SSI eligibility criteria—most importantly, the $2,000 resource limit.

The critical phrase is "solely because of DAC benefits." If the individual loses SSI for any other reason—exceeding the resource limit, performing Substantial Gainful Activity, or failing a medical redetermination—Protected DAC does not apply, and Medicaid eligibility must be established through a different pathway.

The Social Security Fairness Act and DAC

The Social Security Fairness Act, signed into law on January 5, 2025, repealed the Windfall Elimination Provision (WEP) and the Government Pension Offset (GPO). These provisions previously reduced Social Security benefits for individuals—and their dependents—who received pensions from government work not covered by Social Security.

In Mississippi, this repeal directly impacts families of state employees, teachers, police officers, and other public servants who worked under retirement plans that did not contribute to Social Security. Before the repeal, a child's DAC benefit could be reduced or eliminated if the parent's government pension triggered the WEP or GPO. After the repeal, these offsets no longer apply, and DAC benefits are paid at their full, unreduced amount.

The result: adult disabled children of Mississippi public servants are now eligible for full DAC benefits based on their parent's record, and the Protected DAC Medicaid rules apply when those benefits cause SSI to stop.

What Families Need to Verify

Protected DAC should be applied automatically by the Mississippi Division of Medicaid, but administrative errors happen. Here is what to check:

Confirm the coverage group. After DAC benefits begin and SSI cash payments stop, contact the Division of Medicaid (1-800-421-2408) or check the individual's Medicaid enrollment status to confirm they are classified under the "Disabled Adult Children" coverage group, not a standard ABD or SSI-linked category that might lapse.

Monitor the resource limit. Protected DAC requires that the individual continue to meet SSI resource criteria—$2,000 for an individual. DAC payments themselves are income, not resources, and do not count against the resource limit as they are received. But if DAC payments accumulate in a bank account above $2,000, the individual is over the resource limit and Protected DAC protection fails. The fix: spend down excess funds each month on qualifying expenses, deposit into an ABLE account (up to $100,000 excluded from the resource limit), or fund a special needs trust.

Understand what DAC income does not affect. DAC benefits do not count as earned income for the Working Disabled Medicaid program's income thresholds. DAC is unearned income under SSA rules. If the individual wants to work while receiving DAC, the earned income from employment is evaluated separately.

File for DAC proactively. The SSA does not automatically initiate DAC claims when a parent retires or becomes disabled. The family must contact the SSA to file for DAC benefits. If the individual is already receiving SSI, adding DAC can result in a higher total income (DAC payment minus the SSI reduction) while preserving Medicaid. If the parent has already been retired or disabled for years and no one has filed, back benefits may be available.

DAC and the ID/DD Waiver

For individuals enrolled in or waiting for Mississippi's ID/DD Waiver, Medicaid coverage is a prerequisite. The waiver cannot be activated without active Medicaid eligibility. Protected DAC ensures that the transition from SSI to DAC does not create a gap in Medicaid that would jeopardize waiver services.

The ID/DD Waiver has its own financial limits—a resource limit of $4,000 and an income limit of $2,982 per month (300% of the Federal Benefit Rate). If the DAC payment exceeds $2,982, the individual may need a Qualified Income Trust (Miller Trust) to remain financially eligible for waiver services while retaining Protected DAC Medicaid for general health coverage. This is a situation where consulting with an attorney experienced in Mississippi Medicaid planning is strongly recommended.

When Protected DAC Does Not Apply

Protected DAC only covers the specific scenario where SSI is lost due to DAC benefits. It does not apply if:

• SSI is terminated due to a medical cessation (the individual is found to no longer be disabled)
• SSI is terminated due to excess resources (bank account over $2,000)
• SSI is terminated due to Substantial Gainful Activity (earnings above $1,690/month in 2026)
• The individual never received SSI in the first place

In these situations, the individual must establish Medicaid eligibility through an alternative pathway—ABD Medicaid, Working Disabled Medicaid, or waiver-based coverage.
