County Assistance Office Pennsylvania: How to Access Disability Benefits

Your County Assistance Office is the single point of contact for almost every public benefit your adult child with a disability needs in Pennsylvania — Medicaid, SNAP, cash assistance, and the intake paperwork that connects to SSI-linked coverage. Yet most families only learn the CAO exists after a coverage gap has already opened.

What a County Assistance Office Actually Does

Pennsylvania's Department of Human Services runs 67 County Assistance Offices (one per county), each staffed by caseworkers from the Office of Income Maintenance. These offices process applications for Medical Assistance (Medicaid), SNAP (food stamps), cash assistance, and LIHEAP energy assistance. For families navigating the disability transition at age 18, the CAO is where you submit Form PA 600 to establish adult Medicaid eligibility after the childhood PH-95 category expires.

The CAO also handles renewals. Every 12 months, your adult child's Medicaid eligibility is reviewed. The renewal notice gives a due date; if the CAO doesn't receive the renewal paperwork by that date, coverage can end, but you can still submit the renewal within 90 days after coverage ends. If you remain eligible, coverage can reopen without a gap. That termination can interrupt therapy sessions, medication refills, and waiver-funded services that all ride on active Medicaid enrollment.

How to Find Your Local CAO

The fastest route is the COMPASS portal at compass.state.pa.us, which lets you search by zip code. You can also call the DHS helpline at 1-800-692-7462 for your county's office address and hours. Most CAOs operate Monday through Friday, 8:00 a.m. to 4:30 p.m., but some counties run satellite offices with limited hours.

When you visit, bring the young adult's Social Security card, photo ID, proof of disability (SSA award letter or BDD determination), proof of income (SSI benefit letter, bank statements for the last 30 days), and proof of residence. Missing even one document means a second trip.

The CAO's Role in the Age-18 Medicaid Transition

When a child turns 18 in Pennsylvania, their PH-95 Medicaid category — the one that ignored parental income entirely — ends automatically. The CAO is responsible for reviewing whether the young adult qualifies for adult Medicaid under Healthy Horizons, SSI-linked Medical Assistance, or MAWD if they're employed.

Under federal ex parte review rules, the CAO is supposed to search electronic data sources and attempt to establish ongoing eligibility before sending a termination notice. In practice, this automated process doesn't always catch every case. Filing the PA 600 yourself — rather than waiting for the CAO to initiate the review — gives you a paper trail and a 30-day processing deadline to hold the office accountable.

If the CAO denies the application or you disagree with their eligibility determination, you have the right to request a fair hearing within 30 days of the denial notice. The appeal is filed through DHS, not through the CAO itself.

Common CAO Mistakes That Cost Families Coverage

The most frequent error families report is the CAO failing to apply the correct Medicaid category. A young adult receiving SSI should receive automatic Medicaid — but if the CAO's system doesn't show the SSI approval (common when SSA's records haven't synced), the caseworker may process the application under income-based rules and deny it. Always bring a copy of the SSI award letter to your appointment.

The second common issue is the CAO not recognizing Disabled Adult Child benefits. When a DAC benefit pushes the young adult's income above the SSI threshold, the CAO must apply Special Medicaid Status — a protected category that disregards the DAC income for Medicaid purposes. Some caseworkers aren't familiar with this provision. If you're told your child "makes too much" because of DAC, ask the supervisor to review the 1634 agreement and Special Medicaid Status rules.

What the CAO Cannot Do

The CAO does not process SSI applications (that's the Social Security Administration), does not manage ODP waiver enrollment (that's the county Administrative Entity), and does not handle guardianship filings (that's Orphans' Court). Families often conflate these systems because they share similar paperwork. The CAO's jurisdiction is strictly limited to DHS-administered programs: Medicaid, SNAP, cash assistance, and energy assistance.
