Oklahoma TEFRA Katie Beckett at Age 18

Families who have used TEFRA (Katie Beckett) coverage to provide Medicaid for their child with a disability — regardless of parental income — face a hard stop at 18. The TEFRA pathway was designed for children, and it does not extend into adulthood. There is no automatic transition to adult SoonerCare. If the family does not file a separate adult Medicaid application at the age-18 transition, the young adult may lose healthcare coverage at exactly the moment they are navigating the most complex administrative transition of their life.

Why TEFRA Ends at 18

The TEFRA/Katie Beckett option exists because of the Tax Equity and Fiscal Responsibility Act of 1982, which allowed states to provide Medicaid to children with disabilities living at home by evaluating only the child's own income and resources — not the parents'. This was critical for families whose income exceeded standard Medicaid limits but whose child needed Medicaid-funded services (therapies, durable medical equipment, nursing care, behavioral health).

At 18, the rationale for TEFRA disappears. The young adult is no longer a minor dependent. Federal SSI already evaluates adults solely on their own income and resources (parental deeming ceases at 18), so the separate TEFRA pathway is no longer needed. The coverage simply terminates.

There is no automatic transition to adult SoonerCare; the burden falls entirely on the family to apply for adult coverage through a different pathway.

The Adult SoonerCare Application

The replacement for TEFRA is the Aged, Blind, and Disabled (ABD) SoonerCare pathway, applied for through the OKDHS Live portal (okdhslive.org) using Form 08MP003E. This is the same application used by SSI recipients seeking SoonerCare coverage — the separate application that Oklahoma requires because the state operates under Section 209(b).

The ABD pathway evaluates the young adult on their individual income and resources:

• Asset limit: $2,000 in countable resources (same as SSI)
• Income cap for long-term care: $2,982/month (300% of the 2026 federal SSI rate)
• Disability determination: If the young adult has been approved for SSI, the SSI award letter serves as evidence of disability. If they have not applied for or been denied SSI, OKDHS conducts its own disability determination.

The key difference from TEFRA: under the ABD pathway, the young adult must independently meet the financial limits. Parental income no longer matters (since deeming ends at 18), but the young adult's own resources — bank accounts, savings, vehicles beyond the first one — must be under $2,000.

Preventing the Coverage Gap

The ideal timeline prevents any break in coverage:

3-6 months before 18: Begin the SSI age-18 redetermination process and start gathering documentation for the adult SoonerCare application.

At 18: File the SSI redetermination packet with the SSA. Simultaneously file the adult SoonerCare application through OKDHS Live, even if the SSI decision has not come back yet. If the young adult meets the disability criteria based on existing medical records, OKDHS can process the ABD application without waiting for the SSI determination.

If SSI is denied: The adult SoonerCare application can still proceed. OKDHS evaluates disability independently under its own criteria. An SSI denial does not automatically disqualify someone from SoonerCare, though the evaluations often reach similar conclusions based on similar medical evidence.

What TEFRA Covered That ABD May Not

Some families notice differences in covered services between the TEFRA pathway and adult ABD SoonerCare. The core medical benefits (doctor visits, prescriptions, hospitalization, behavioral health) continue under adult SoonerCare; families should confirm which pediatric-specific services and coverage rules apply to the young adult's new pathway.

Adults with developmental disabilities who need community-based supports (daily living assistance, respite care, job coaching) must qualify for those services through DDS Home and Community-Based waivers, which are separate from SoonerCare enrollment. Being enrolled in SoonerCare is a prerequisite for DDS waiver services, but SoonerCare alone does not provide waiver-level supports.
