In short: Montana's CHIP program covers medically necessary ABA therapy for children with an autism diagnosis. Families typically pay low or no copays, and there are no annual or lifetime dollar caps on ABA. Our free service can help you find a vetted, BCBA-led provider who accepts CHIP in your area.

Key takeaways

  • Montana CHIP covers ABA therapy as a medically necessary treatment for autism, with no annual or lifetime dollar limits.
  • Eligibility is based on family income, and children must have a formal autism diagnosis from a qualified professional.
  • Copays for ABA visits are typically low or $0, depending on your specific CHIP plan.
  • You need a referral or prescription from your child's doctor to start ABA services under CHIP.

What Is CHIP and How Does It Cover ABA in Montana?

Montana's Children's Health Insurance Program (CHIP) is a state-federal partnership that provides affordable health coverage for children in families with incomes too high for Medicaid but too low for private insurance. In Montana, CHIP is administered by the Department of Public Health and Human Services (DPHHS) and is known as the Healthy Montana Kids (HMK) program. For families raising a child with autism, one of the most valuable benefits is coverage for Applied Behavior Analysis (ABA) therapy.

ABA is an evidence-based therapy that helps children with autism develop communication, social, and daily living skills while reducing challenging behaviors. Under Montana CHIP, ABA is considered a medically necessary treatment when prescribed by a doctor. This means your child can receive one-on-one therapy from a Board Certified Behavior Analyst (BCBA) or a supervised Registered Behavior Technician (RBT) without worrying about high out-of-pocket costs.

Importantly, Montana CHIP does not impose annual or lifetime dollar caps on ABA services. This is a significant advantage over many private insurance plans, which may limit the number of visits or total spending. However, coverage is subject to medical necessity reviews, so your provider will need to document progress and justify ongoing treatment.

Who Is Eligible for CHIP ABA Coverage in Montana?

Income and Age Requirements

To qualify for Montana CHIP, your family's income must fall between 141% and 261% of the federal poverty level (FPL). For a family of four in 2024, that means a monthly income between roughly $3,500 and $6,500. Children must be under age 19 and uninsured (or underinsured) to enroll. If your income is below 141% FPL, your child may qualify for Montana Medicaid instead, which also covers ABA.

Autism Diagnosis Requirement

Your child must have a formal diagnosis of autism spectrum disorder (ASD) from a qualified professional, such as a developmental pediatrician, child psychiatrist, or psychologist. The diagnosis must be documented in your child's medical records. CHIP will not cover ABA for other conditions, such as ADHD or developmental delays without an autism diagnosis.

Residency and Citizenship

You must be a Montana resident and your child must be a U.S. citizen or qualified non-citizen. Proof of residency and citizenship will be required during the application process.

What ABA Services Does Montana CHIP Cover?

Montana CHIP covers a comprehensive range of ABA services, including:

  • Initial assessment and treatment planning by a BCBA to create an individualized plan.
  • Direct one-on-one therapy with a BCBA or RBT, typically in-home, clinic, or community settings.
  • Parent training and caregiver support to help you implement strategies at home.
  • Supervision and case management by the BCBA to ensure quality and progress.
  • Behavioral consultation for challenging behaviors or skill deficits.

Services must be deemed medically necessary and authorized by CHIP. Your provider will submit treatment plans and progress reports for review. Coverage typically continues as long as the child shows measurable improvement and the therapy remains appropriate.

How Much Does ABA Cost Under Montana CHIP?

One of the biggest advantages of CHIP is its affordability. Most families pay little to nothing for ABA therapy. Here's what to expect:

  • Monthly premiums: Montana CHIP charges a low monthly premium based on income, usually between $15 and $50 per family.
  • Copays for ABA visits: Many CHIP plans have $0 copays for therapy visits. Some may charge a small copay (e.g., $5 per session), but this is rare for ABA.
  • No deductibles or coinsurance: Unlike many private plans, CHIP typically has no deductible for ABA, and coinsurance is minimal or absent.
  • No annual or lifetime caps: As mentioned, there are no dollar limits on ABA services, though medical necessity reviews apply.

If you have questions about your specific plan's costs, contact the HMK customer service line at 1-877-543-7669.

How to Get ABA Therapy Through Montana CHIP

Step 1: Enroll in CHIP

If your child isn't already enrolled, apply online at the Montana DPHHS website or call 1-877-543-7669. You'll need to provide income documentation, proof of residency, and your child's birth certificate. Once approved, you'll receive a member ID card and plan details.

Step 2: Get an Autism Diagnosis

If your child doesn't have a formal diagnosis, schedule an evaluation with a qualified professional. Your pediatrician can refer you to a specialist. Keep all diagnostic reports handy.

Step 3: Obtain a Prescription for ABA

Ask your child's doctor to write a prescription or referral for ABA therapy. This is required by CHIP to initiate coverage. The prescription should include the diagnosis and a recommendation for ABA.

Common Mistakes to Avoid When Using CHIP for ABA

  • Not getting a prescription first: Some families start looking for providers before having a doctor's prescription. This can delay authorization. Always get the prescription first.
  • Assuming all providers accept CHIP: Not all ABA providers are enrolled with Montana CHIP. Always verify before scheduling. Our matching service ensures you only see providers who accept your plan.
  • Missing reauthorization deadlines: CHIP requires periodic reauthorization (usually every 6-12 months). Your provider will handle this, but stay in touch to avoid gaps in coverage.
  • Ignoring parent training: CHIP covers parent training, which is crucial for generalizing skills at home. Don't skip these sessions.
  • Not appealing denials: If a service is denied, you have the right to appeal. Work with your provider to submit additional documentation.
