Medicaid Transition at 18 Pennsylvania: PH-95 to Adult Coverage

The PH-95 Cliff

If your child has been receiving Pennsylvania Medical Assistance through the PH-95 category — sometimes called the "disabled child loophole" — coverage under that category ends when your child turns 18. The adult then needs to be evaluated under an adult Medicaid category or another coverage pathway.

PH-95 is extraordinarily generous because it ignores parental income and resources entirely. A child with a qualifying disability gets full Medicaid regardless of how much the family earns. That protection vanishes at 18, and the transition to adult Medicaid categories requires action on your part. The County Assistance Office does not automatically shift your child to an adult category.

Common Pathways to Adult Medicaid

Once PH-95 ends, your adult child may qualify under one of several adult categories, including:

SSI-linked Medicaid. If your child is approved for adult SSI, Pennsylvania automatically enrolls them in Medical Assistance. No separate application is needed — SSI approval triggers Medicaid. This is the simplest pathway, but it depends on passing the SSI age-18 redetermination under the adult disability standard.

Healthy Horizons. This is Pennsylvania's standard adult Medicaid category for individuals with disabilities who aren't on SSI. Income and asset limits apply: the individual's countable income must be at or below the Medicaid Special Income Limit ($2,982 per month in 2026), and assets must stay under $8,000 for individuals with income at or below that limit. Because parental income is no longer deemed to the adult child, many young adults whose parents' income previously disqualified them from standard adult Medicaid now qualify on their own.

MAWD. If the young adult is working, the Medical Assistance for Workers with Disabilities program allows countable income below 250% of the Federal Poverty Level ($3,325 per month) with a $10,000 asset limit and a 5% income premium. MAWD is the right choice when the individual earns too much for Healthy Horizons but needs Medicaid to continue.

How to Apply Before Coverage Lapses

Start the adult Medicaid application when your child turns 18. You can apply through COMPASS (Pennsylvania's online benefits portal) or by submitting a paper PA 600 form at your local County Assistance Office.

The CAO has a 30-day processing deadline from the date it receives a complete application. Submit promptly when PH-95 ends so the adult category can be evaluated. Filing late creates a gap — and a gap in Medicaid can interrupt prescriptions, therapy authorizations, and specialist appointments that your child depends on.

When you apply, explicitly note on the application that the individual is transitioning from PH-95 and request evaluation under all applicable adult categories. CAO workers don't always evaluate every possibility unless you flag it.

What If SSI Is Denied or Delayed?

The SSI age-18 redetermination can take several months. During that processing time, automatic SSI-linked Medicaid isn't available because there's no SSI approval yet. This is exactly why you need to file the COMPASS application independently — it creates a standalone Medicaid determination that doesn't depend on SSI timing.

If SSI is eventually denied, the standalone adult Medicaid determination keeps coverage in place (assuming the individual meets income and asset limits under Healthy Horizons or another adult category). If SSI is later approved on appeal, ask the CAO to confirm the effective date of SSI-linked Medicaid rather than assuming it will retroactively cover every gap.

The Ex Parte Review Requirement

Under federal rules, Pennsylvania CAOs are supposed to conduct an ex parte review before terminating any Medicaid category. That means the CAO should check available electronic records to see if the individual qualifies under a different adult category before sending a termination notice. In practice, this review doesn't always happen — particularly during the volume surge when large cohorts of PH-95 children age out simultaneously.

If you receive a Medical Assistance termination notice, request a fair hearing by the deadline stated in the notice. To ask for continued benefits during the appeal, follow the notice's instructions; do not assume the SSI continuation rule is identical.

Protecting Coverage During the DAC Transition

If your child eventually receives Disabled Adult Child benefits from a parent's Social Security record, the DAC income can push them off standard SSI-linked Medicaid. Federal law provides Special Medicaid Status for exactly this situation — the CAO must disregard the DAC income when determining ongoing Medicaid eligibility. But you may need to explicitly request this disregard at your County Assistance Office with copies of the DAC award letter and the SSI cessation notice.

The Pennsylvania SSI at 18 & Adult Disability Benefits Guide includes a Medicaid transition timeline that coordinates the PH-95 end date, COMPASS application, SSI redetermination, and DAC filing into a single checklist so nothing falls through the cracks.
