Hawaii DDD Application and Intake Process

Who Qualifies for DDD Services in Hawaii

The Hawaii Department of Health Developmental Disabilities Division (DOH-DDD) serves individuals with severe, chronic disabilities that manifested before age 22 and cause substantial functional limitations in three or more major life areas — self-care, receptive and expressive language, learning, mobility, self-direction, capacity for independent living, or economic self-sufficiency.

Unlike SSI and Med-QUEST, DDD eligibility has no income or asset limits. It is entirely clinical and functional. This means a family that earns too much for SSI can still qualify their adult child for DDD services and, through DDD, access the Medicaid I/DD Waiver.

The Five-Step Intake Process

Step 1: Contact your island's intake office. DDD operates localized intake offices, not a centralized application system. Reach the right office directly:

• Oahu: (808) 733-9191
• Hawaii Island — Hilo: (808) 974-4280
• Hawaii Island — Kona: (808) 327-6212
• Hawaii Island — Waimea: (808) 887-6064
• Maui: (808) 243-4625
• Molokai: (808) 553-7898
• Kauai: (808) 241-3406

Neighbor island families can also submit documents electronically — for example, [email protected] for Hawaii Island, [email protected] for Maui/Molokai/Lanai, and [email protected] for Kauai.

Step 2: Sign the Application for DDD Services. This starts the 90-working-day clock. All required documentation must be submitted within that window, or the file is administratively closed.

Step 3: Gather and submit clinical evidence. The documentation requirements are specific:

• Comprehensive psychological evaluation with full-scale IQ scores
• Standardized adaptive behavior assessment (Vineland-3 or ABAS-3)
• Medical summary from the treating physician documenting the developmental disability
• Proof of Hawaii residency

Step 4: Complete the intake interview. A DDD intake worker conducts the interview with the applicant and family, reviewing the submitted documentation and functional history.

Step 5: Eligibility determination. The Oahu Intake Section performs the final clinical review and has 30 working days from receipt of all documents to issue a formal decision.

The 90-Day Deadline Is Not Flexible

This is the most common point of failure. Once you sign the application, you have exactly 90 working days to submit every required evaluation, residency verification, and medical record. If the file is not complete by day 90, DDD closes it — and you restart from the beginning.

The practical challenge: getting a comprehensive psychological evaluation scheduled and completed within that window. Most developmental psychologists in Hawaii have booking lead times of 8 to 16 weeks, especially on the neighbor islands. Start scheduling the evaluation before you even contact DDD intake.

What Happens After Approval

Once DDD determines your child is eligible, a case manager is assigned from the local Case Management Unit (CMU). The next step is the Supports Intensity Scale — Adult (SIS-A) assessment, a standardized tool that measures your child's support needs across multiple domains.

The SIS-A results help inform the level of services authorized under the Medicaid I/DD Waiver. This assessment can be conducted via videoconference, which is especially valuable for neighbor island families who would otherwise need to travel to Oahu.

From DDD to the Waiver

DDD eligibility is the gateway to the Medicaid I/DD Waiver, which funds the actual services — personal assistance, residential habilitation, adult day health, and more. But DDD eligibility alone isn't enough. Your child also needs active Med-QUEST coverage, approval for the waiver's long-term-care benefit, and an ICF-IID Level of Care certification (Form DHS 1150-C) completed by their physician and submitted by the DDD case manager.

The Hawaii SSI at 18 & Adult Disability Benefits Guide maps the entire sequence from DDD intake through waiver enrollment, with a documentation checklist that tracks the 90-day deadline alongside the parallel SSI and Med-QUEST applications.
