Autism Evaluation in Montana: 2026 Guide

Montana terminated its dedicated Children's Autism Waiver (which had served ages 1-4) on July 1, 2019, and has not replaced it with an autism-specific program; children now access services through the Children's, Comprehensive (0208), and Community Supports waivers operated by the DPHHS Developmental Disabilities Program. The 0208 Comprehensive Waiver has roughly 2,100 Montanans on its waiting list with an average wait of about 7 years, and overall DPHHS reports about 1,749 people with developmental disabilities awaiting services statewide.

An autism evaluation in Montana happens through one of three channels. Private clinics produce a clinical diagnosis and typically book 6 to 18 months out. Early Intervention serves children under 3 and is built on federal IDEA Part C deadlines. The public school child-find process serves ages 3 and up and runs on a 60 calendar day federal evaluation clock. None of these pathways are mutually exclusive.

The three pathways for an autism evaluation in Montana

1. Early Intervention (under age 3): Part C Early Intervention (Montana Milestones)

Free, no diagnosis or doctor referral required, federally guaranteed under IDEA Part C. Montana's Part C system, known operationally as Montana Milestones / Part C Early Intervention, is administered by the DPHHS Developmental Services Division Family Support Services Bureau through Family Education and Support Services (FESS) regional offices that contract with the state. Per the federal Part C rule, evaluation, assessment, and the initial IFSP meeting must occur within 45 calendar days of referral. Parents and providers can call DPHHS Developmental Services Division at 406-444-2995 or contact a regional FESS office directly. Services typically begin within 30 days of the signed IFSP.

2. Private developmental pediatrician or autism clinic

Typical waitlist in Montana: 6 to 18 months. Cost with insurance: Copay or coinsurance after deductible varies by plan; group disability plans must cover diagnosis and treatment of autism spectrum disorder for children 18 and younger under MCA 33-22-515. The statute permits annual benefit caps of $50,000 (age 8 and younger) and $20,000 (ages 9 through 18), but per federal Mental Health Parity and Addiction Equity Act, those caps are typically unenforceable in fully-insured plans. The Montana Mental Health Parity Act at MCA 33-22-701 through 33-22-710 also applies. Without insurance: Costs vary widely by evaluator and scope. Commonly reported ranges for a full diagnostic battery fall around $1,500 to $4,500. Billings, Missoula, and Great Falls academic and hospital systems tend to run higher than community practices, and many rural Montana families travel several hours to reach a developmental pediatrician. Ask each evaluator for a detailed estimate before scheduling.

Shodair Children's Hospital in Helena runs a developmental and behavioral health evaluation team for autism and related conditions. Billings Clinic and St. Vincent Healthcare in Billings, Community Medical Center in Missoula, and Benefis Health System in Great Falls provide developmental and behavioral pediatrics. The University of Montana Rural Institute for Inclusive Communities (Montana's University Center for Excellence in Developmental Disabilities) coordinates training and outreach for community evaluators. Rural Montana families typically travel several hours or use telehealth follow-up after an initial in-person evaluation.

3. School district evaluation (age 3 and up)

Free, federally guaranteed under IDEA Part B (Child Find). Submit a written request to your district's Director of Special Education or your child's building principal. Per ARM 10.16.3321, the public agency must provide prior written notice and obtain signed parental consent before conducting an initial evaluation. The 60 calendar day initial evaluation clock starts the date the public agency receives signed parental consent.

Timeline: Per ARM 10.16.3321 (Comprehensive Educational Evaluation Process and Reevaluations), Montana incorporates by reference the federal initial evaluation timeline at 34 CFR §300.301 through §300.311, requiring the initial evaluation to be completed within 60 calendar days from the date the public agency receives signed parental consent. This mirrors the federal 60 calendar day IDEA floor at 34 CFR §300.301(c)(1)(i). The 60 day clock does not apply if the parent repeatedly fails or refuses to produce the child for evaluation, or if the child enrolls in a different district after consent and before evaluation completion. // CHECKED 2026-05-18

Cost and coverage in Montana

Insurance mandate

Yes. Montana's autism insurance mandate is codified at MCA 33-22-515 (Coverage of autism spectrum disorders) within Title 33 Chapter 22 Part 5 (Group Disability Insurance). Group disability policies, certificates of insurance, or membership contracts delivered, issued, renewed, extended, or modified in Montana must provide coverage for diagnosis and treatment of autism spectrum disorder for a covered child 18 years of age or younger. The statute permits annual benefit caps of $50,000 for a child age 8 or younger and $20,000 for a child age 9 through 18; in practice, federal Mental Health Parity and Addiction Equity Act compliance typically prevents enforcement of these dollar caps in fully-insured plans. Special deductible, coinsurance, copayment, or other limitations not generally applicable to other medical care covered under the plan may not be imposed on autism coverage. The Montana Mental Health Parity Act at MCA 33-22-701 through 33-22-710 also applies. Self-funded employer plans are governed by ERISA and are not subject to MCA 33-22-515.

Medicaid waiver: 0208 Developmental Disabilities Comprehensive Waiver (Montana DPHHS Developmental Services Division)

Montana residents of any age with intellectual or developmental disability (including autism with substantial functional limitations) originating before age 18, who meet ICF/IID level of care. The 0208 Waiver serves both children and adults; Family Education and Support Services (FESS) is available to children under 18 not yet on the waiver. Children under 3 access services through Part C Early Intervention instead. Per DPHHS, the 0208 Comprehensive Waiver has a waitlist of approximately 1,749 DD-specific individuals with an average wait time of approximately 7 years due to legislatively-capped enrollment slots. // CHECKED 2026-05-18 Note: the waitlist for full waiver enrollment in Montana is currently around 7 years; apply early.

Do I need a referral from my pediatrician to start in Montana?
No, not for Part C Early Intervention (Montana Milestones) (Early Intervention). You can self-refer directly using the program's referral page. For private clinics, some require a pediatrician's referral form for insurance billing; many do not. Always call the clinic to confirm before joining the waitlist, since being on the wrong list wastes months.
My child is on a long waitlist in Montana. What can I do right now?
Three things, in order. First, refer to Part C Early Intervention (Montana Milestones) (under 3) or your school district (3+); these run on legal deadlines, not waitlists. Second, document what you see at home (videos, behavior patterns, sleep, sensory triggers) so the eventual evaluation has data to work with. Third, start no-diagnosis-required supports: visual schedules, sensory accommodations, predictable routines. Our free 30-day plan tool combines all three based on your specific situation in Montana.
