DC HCBS and IFS Waivers: Medicaid Disability Services After High School

Two Waivers, Different Scopes

DC's Department on Disability Services (DDS) administers two Medicaid Home and Community-Based Services waivers through the Developmental Disabilities Administration (DDA):

The HCBS Waiver (IDD Waiver) — The comprehensive waiver. Covers residential services, day habilitation, supported employment, community integration, respite, and other long-term supports. Designed for individuals with significant support needs who require ongoing, intensive services.

The Individual and Family Support (IFS) Waiver — The streamlined waiver. Covers community-based services like adult education support, respite, employment services, and environmental modifications. Carries an annual spending cap of $75,000. Does not cover residential placements.

Both waivers require DDA eligibility as a prerequisite. You can't apply for either waiver without first being determined eligible for DDA services.

DDA Eligibility: The Gateway

DDA eligibility was significantly expanded by the Developmental Disability Eligibility Reform Amendment Act of 2022 (D.C. Law 24-117). Before the reform, eligibility required a documented intellectual disability — specifically an IQ of 69 or below with concurrent adaptive functioning deficits.

The 2022 reform expanded eligibility in two critical ways:

1. Individuals with developmental disabilities who don't have an intellectual disability diagnosis can now qualify. This opened the door for people with autism, cerebral palsy, and other developmental conditions that affect adaptive functioning but don't necessarily produce a low IQ score.
2. The onset limit for a qualifying disability extended to age 22, aligning with the FAPE exit timeline.

To apply, families complete the DDA Intake Application and Person-Centered Questionnaire through the DDA Intake and Eligibility Determination Unit (IEDU). Required documentation includes a psychological evaluation documenting the disability and concurrent deficits in at least two of three adaptive functioning domains: conceptual, social, and practical.

Waiver Access vs. DDA Eligibility — Not the Same Thing

This trips up families constantly. Getting determined eligible for DDA does not automatically enroll a student in a waiver program. DDA eligibility means the person qualifies for DDA coordination and case management. Waiver enrollment is a separate step.

To access either waiver, the individual must:

• Be at least 18 years old
• Be active on DC Medicaid
• Meet the Intermediate Care Facility Level of Care (LOC) as evaluated by the Medicaid Waiver Unit
• Choose waiver services over institutional care

The Level of Care assessment is the gatekeeping step. The student's service coordinator submits an application packet to the Medicaid Waiver Unit. That packet must include the psychological evaluations and the DDA Level of Need (LON) Assessment and Screening Tool. The documentation needs to clearly show that the individual requires continuous, hands-on support in at least three major life activities.

The $75,000 IFS Cap: What It Means in Practice

The IFS waiver's annual spending cap of $75,000 covers all community-based services authorized under the waiver. That includes:

• Supported employment and job coaching
• Community integration activities
• Adult education support
• Respite care
• Environmental modifications to the home

It does not cover residential placements — those require the HCBS waiver.

The $75,000 cap is an annual limit, and whether it is sufficient depends on the services authorized for the individual. Residential placements are excluded from IFS and require the HCBS waiver. The HCBS waiver may involve a longer enrollment process and potentially a waitlist.

Timing the Application for Transition-Age Youth

The ideal timeline:

• By age 17: Begin gathering documentation — psychological evaluations, adaptive behavior assessments, medical records. The DDA application requires specific clinical documentation, and getting it assembled takes time.
• At age 18: Submit the DDA Intake Application. Because waiver access requires the individual to be at least 18, use the earlier period to gather documentation and ask DDA when to begin its eligibility process.
• Ages 18–21: While the student is still receiving FAPE and participating in school-based transition programs, work with the DDA service coordinator to develop the Individual Service Plan (ISP) using person-centered planning.
• Before age-22 exit: Ensure the waiver application packet has been submitted to the Medicaid Waiver Unit and the Level of Care assessment is complete. Aim to reduce the gap between school-funded services and waiver-funded services.

How This Connects to the IEP

The IEP team plays a direct role in waiver planning. Under OSSE requirements, the LEA must obtain prior written consent from the parent (or adult student) before inviting DDA representatives to IEP meetings where transition services are discussed. Once consent is given, the DDA service coordinator should attend transition IEP meetings and coordinate the ISP with the school-based transition plan.

If DDA staff are invited but don't show up, document the absence in the meeting notes. This creates a record that matters if the family needs to escalate coordination failures later.

The DC IEP Transition to Adulthood Guide maps the DDA and waiver application timeline against the school-based transition calendar, showing families exactly when each piece of documentation is due and how the IEP, IPE, and ISP work together during the handoff from school to adult services.
