Indiana Autism Waiver Services: What Is Actually Available

Indiana does not have a standalone autism waiver. That is the first thing families need to understand, because the search for an "autism waiver" in Indiana leads to dead ends and misinformation. What Indiana has is a set of general developmental disability waivers — the Family Supports Waiver (FSW) and the Community Integration and Habilitation (CIH) waiver — that serve individuals with autism alongside those with intellectual disabilities and other developmental conditions.

How Autism Qualifies Under BDS Waivers

To access FSW or CIH waiver services, an individual with autism must meet the same eligibility criteria as any other applicant:

Diagnostic requirement. The individual must have a documented developmental disability — including autism spectrum disorder — with onset before age 22 that is expected to continue indefinitely. An autism diagnosis can satisfy the diagnostic portion of this criterion, but eligibility also requires the level-of-care and financial requirements below.

Level of care. The individual must meet the Intermediate Care Facility (ICF/IID) level of care, meaning substantial functional limitations in at least three of six major life areas: self-care, learning, self-direction, capacity for independent living, understanding and use of language, and mobility.

This is where many adults with autism get tripped up. An individual with high-masking autism or strong verbal skills may test well on the interRAI assessment's brief three-day lookback window, even though their long-term support needs are significant. The interRAI tool's binary questioning format and automated scoring have produced a notably higher denial rate since its January 2026 implementation — historical data shows the denial rate jumped from 0.2% under the old LOCSI tool to approximately 6% under interRAI, with initial weeks peaking near 15%.

ABA and Behavioral Services

Applied Behavior Analysis (ABA) therapy for children with autism is covered under Indiana Medicaid as an Early and Periodic Screening, Diagnostic, and Treatment (EPSDT) service through age 20. After 21, ABA is not a standard Medicaid benefit in Indiana.

Under the BDS waivers, behavioral support services are available — but these are not the same as intensive ABA. Waiver-funded behavioral support typically involves a behavior consultant developing a behavior support plan, training direct support staff and family members to implement it, and conducting periodic reassessments. The intensity and structure differ substantially from the 20–40 hour/week ABA programs that children may have received.

What Waiver Services Cover for Adults with Autism

FSW and CIH provide a range of services relevant to adults on the spectrum:

• Participant Assistance and Care (PAC) — direct support for daily living activities, community access, and skill development
• Respite — temporary relief for family caregivers
• Day habilitation — structured daytime programming focused on socialization, community participation, and functional skills
• Supported employment — job coaching and workplace placement with gradual fading of support
• Environmental modifications — home adaptations for safety (relevant for individuals with sensory needs or elopement risk)
• Transportation — getting to and from services, employment, and community activities
• Benefits counseling — up to 6 hours per calendar year under the August 2026 amendments

Common Denial Scenarios and What to Do

interRAI denial for "not meeting level of care." Request the complete interRAI assessment record, including the questionnaire, case manager notes, and scoring rubrics. Identify questions where the three-day lookback window failed to capture the individual's typical presentation — autism symptoms fluctuate, and a good three-day stretch does not represent long-term need. File a written appeal within 33 calendar days of the notice. To preserve existing services while the appeal is pending, request service preservation within 10 days or before the effective date, as applicable.

Diagnostic gap. Some adults with autism were diagnosed in childhood under DSM-IV criteria that used labels like Asperger syndrome or PDD-NOS. BDS requires documentation of a current qualifying diagnosis. If the most recent evaluation predates the DSM-5 transition, an updated diagnostic evaluation using current criteria may be needed before the waiver application can proceed.

Age-out timing. Adults with autism who aged out of school-based ABA or EPSDT services often face a gap before waiver services begin. Filing the BDS Gateway application well before the school exit date — ideally years before — secures a waitlist position and enables claiming the school-exit priority category for FSW access between ages 18 and 24.
