Louisiana Medicaid Purchase Plan: How Working Adults With Disabilities Keep Coverage

The Problem the Medicaid Purchase Plan Solves

An adult child on SSI in Louisiana gets automatic Medicaid through the state's Section 1634 agreement with SSA. But what happens when that person starts working? After applicable exclusions, earned income reduces the SSI check by $1 for every $2 earned, and if income pushes them off SSI entirely, the automatic Medicaid link breaks.

The Louisiana Medicaid Purchase Plan (MPP) exists precisely for this situation. It lets disabled adults earn income — sometimes well above the standard SSI limit — while maintaining full Medicaid coverage under expanded financial thresholds.

MPP Eligibility and 2026 Financial Limits

The MPP was expanded through administrative rule changes finalized in 2025–2026. The current limits for an individual:

• Countable income: Up to 200% of the Federal Poverty Level (approximately $2,660/month for a single person in 2026)
• Countable resources: Up to $25,000 — dramatically higher than SSI's $2,000 limit
• Age range: 16 to 65
• Disability requirement: Must meet SSA's definition of disability (current or prior SSI/SSDI determination qualifies)
• Work requirement: Must be engaged in employment that produces earned income

Workers whose countable income exceeds 150% FPL and remains within the MPP program limit pay a $131 monthly premium for MPP coverage.

There's an additional requirement that catches some families off guard: the individual must accept any free employer-sponsored health insurance available to them. MPP then acts as secondary coverage, filling the gaps that employer insurance doesn't cover (which, for complex disability-related care, are often substantial).

How MPP Connects to the Age-18 Transition

For families navigating the transition from school to adult life, MPP creates a pathway that didn't exist a generation ago. The traditional fear was that employment would cost the adult child their healthcare — the "benefits cliff" that kept people from working. MPP softens that cliff considerably.

Here's the practical sequence:

1. The adult child receives SSI and automatic Medicaid
2. They begin working (through an OIDD-funded supported employment program, LRS job placement, or independent employment)
3. Earned income gradually reduces the SSI check
4. If SSI terminates due to earnings, Medicaid may continue under Section 1619(b) protections if the individual meets that program's requirements
5. If income rises above 1619(b) thresholds, the individual can apply for MPP — which has the higher $25,000 resource limit

The $25,000 resource limit is especially significant. Combined with an ABLE account ($100,000 excluded from SSI resource counting) and a special needs trust (fully excluded), a working disabled adult in Louisiana can accumulate meaningful savings without losing healthcare.

The Family Opportunity Act: Under-19 Coverage

For children under 19 whose families earn too much for standard Medicaid but whose child has a qualifying disability, Louisiana administers the Family Opportunity Act (FOA) buy-in program. The 2026 income limits are substantially higher than standard Medicaid:

• Single-person household: $3,990/month
• Family of four: $8,250/month
• No asset test applies
• Sliding-scale premium based on family income

FOA coverage is relevant for families in the pre-transition window — particularly those whose household income previously triggered "deeming" that disqualified the child from SSI during childhood. Once the child turns 18 and deeming ends, they may qualify for SSI directly, shifting to the standard Medicaid pathway.

Medicaid Expansion as a Safety Net

Louisiana expanded Medicaid in 2016 under the Affordable Care Act. For adults aged 19–64, the expansion pathway covers individuals with household income up to 138% FPL (approximately $1,836/month for a single person in 2026) — with no asset test.

This matters for the transition because Medicaid expansion acts as a catch-all. If an adult child doesn't qualify for SSI-linked Medicaid, doesn't meet the work requirement for MPP, and doesn't have an active waiver, expansion Medicaid can still provide healthcare coverage as long as their income is low enough.

The coverage isn't identical — expansion Medicaid may not include all the specialized disability services available through waiver programs — but it prevents the most dangerous outcome: a disabled adult with no healthcare coverage at all.

Applying for MPP

The application process runs through the Louisiana Department of Health, not through SSA. The key steps:

1. Confirm that the individual meets SSA's disability definition (an existing SSI or SSDI determination works)
2. Document current employment and earned income
3. Document countable resources (must be at or below $25,000)
4. Submit the application through the local Medicaid office or online portal at lamedicaid.com
5. Verify whether the individual has access to employer-sponsored insurance (must accept if available)

Processing time depends on the eligibility review. Do not assume that an MPP application itself continues coverage; ask LDH which continuation or alternative pathway applies while the application is pending.

The Louisiana SSI at 18 & Adult Disability Benefits Guide walks through the full Medicaid protection chain — from automatic Section 1634 enrollment through Pickle Amendment protections, DAC Medicaid, 1619(b), and the Medicaid Purchase Plan — so families can identify which pathway applies at each stage of the transition.
