PerformCare to DDD Transition in New Jersey: Avoiding the Age-21 Service Gap

PerformCare services end the day before your child turns 21. If adult DDD services aren't already authorized and providers aren't already lined up, the family may face a gap at the handoff. This gap is the single most common crisis point for New Jersey families of young adults with developmental disabilities.

How the Two Systems Work

PerformCare (the Children's System of Care, or CSOC) operates under the Department of Children and Families. It provides behavioral health services, in-home supports, crisis intervention, and care management for children and youth with developmental disabilities and mental health needs. Families call one number, get a care manager, and that person coordinates services.

The Division of Developmental Disabilities (DDD) operates under a completely different department — the Department of Human Services. DDD runs two adult Medicaid waiver programs: the Supports Program (no waiting list) and the Community Care Program (chronological waiting list for residential services). DDD uses a different assessment tool, different providers, different funding structures, and different case management.

These two systems use separate assessments, providers, funding structures, and case management; families should not assume that a client will transfer automatically. The family is the bridge.

The Timeline You Need to Follow

Ages 18–19: Start the DDD intake process. You can submit the DDD application as early as 18. The application establishes eligibility for adult services — it does not start services yet. This early filing gives you a buffer if documentation needs to be corrected or resubmitted.

Age 20: Complete the NJCAT. The New Jersey Comprehensive Assessment Tool evaluates your child's support needs across self-care, behavioral, and medical domains. The resulting score assigns a funding tier that determines the annual budget for adult services. Schedule this early enough that results are back well before the 21st birthday.

Spring before 21: Select a Support Coordination Agency. You choose the SCA — DDD does not assign one. The Support Coordinator from your chosen agency then works with you to develop the Individualized Service Plan (ISP), identify providers, and authorize services.

Before the 21st birthday: Confirm everything is active. Active Medicaid enrollment, approved ISP, selected providers with signed service authorizations, and a confirmed start date that aligns with the day PerformCare terminates.

What PerformCare Covers That DDD Does Not

The service overlap between these systems is not one-to-one. PerformCare provides:

• Behavioral health crisis intervention (24/7 hotline)
• Intensive in-community services and mobile response
• Therapeutic foster care and residential treatment

DDD's Supports Program covers day habilitation, supported employment, individual supports, respite, and behavioral supports — but the behavioral health crisis infrastructure looks different. Families who relied heavily on PerformCare's crisis services should plan for how that function will be handled under the adult system. DDD's behavioral supports are authorized through the ISP, not through a call-in crisis system.

The Medicaid Prerequisite

DDD requires active Medicaid, but the enrollment pathway often changes at 18. Before 18, most children are covered through a parent's NJ FamilyCare plan or through a pediatric Medicaid category.

At 18, if the young adult qualifies for SSI, Medicaid enrolls automatically (New Jersey is a Section 1634 state). If SSI is denied, you need to secure Medicaid through an alternative pathway — ABD (Aged, Blind, and Disabled) Medicaid Only through the County Board of Social Services, or NJ WorkAbility if the young adult is employed. Any lapse in Medicaid coverage at 21 freezes DDD services, even if the ISP is fully approved.

Why Families Get Caught

Timing assumption. Many families assume that because PerformCare and DDD are both state agencies, the handoff will be coordinated. It isn't. Do not assume that PerformCare will automatically notify DDD when a client is aging out or that DDD will monitor PerformCare's caseload.

Late DDD application. Submitting the DDD application at 20 instead of 18 leaves almost no margin for corrections, NJCAT scheduling delays, or documentation requests. The intake process routinely takes months.

Support Coordination delay. Families sometimes wait for DDD to assign a Support Coordinator rather than proactively selecting a Support Coordination Agency. DDD does not assign — you choose, and the choice itself can take weeks to process.

Medicaid lapse. If SSI is denied at the age-18 redetermination and the family doesn't immediately apply for alternative Medicaid, the young adult arrives at 21 with no active Medicaid coverage. DDD cannot authorize services without it.

Building the Bridge Yourself

The core principle: treat this as a multi-year project that starts at 18, not a single event at 21. Every step has dependencies (DDD eligibility requires Medicaid; Medicaid requires SSI or an alternative application; ISP development requires NJCAT results and SCA selection), and each dependency has its own processing timeline.

Our New Jersey SSI at 18 & Adult Disability Benefits Guide provides the chronological transition workbook that maps every application, assessment, and deadline across all four agencies — SSA, Medicaid, DDD, and DVRS — with tracking worksheets for each handoff point. The guide was built specifically for this age-21 cliff.
