Indiana Medicaid’s policy on Applied Behavior Analysis (ABA) therapy is designed to support children and young adults with autism and other behavioral conditions, but it has seen recent updates that could affect access to care.

These updated policies have raised concerns due to specific changes to reimbursement rates, which could mean limited access to therapies in communities that need them most, such as rural and low-income areas. The key aspects of the new policy include a standardized fee schedule with updated reimbursement rates for ABA services. These changes aim to bring consistency across providers but have sparked concerns among families and therapy centers about the impact on access to care in the absence of private insurance.

Indiana Medicaid offers a range of ABA therapy services to support children with autism. Comprehensive ABA therapy is intensive, focusing on skill-building in areas like language and motor skills, and is ideal for younger children or those with more severe symptoms, requiring several hours of weekly one-on-one therapy.

For children with specific behavioral challenges like aggression, focused ABA therapy provides targeted interventions with fewer weekly hours. Parent training is also included to help caregivers apply ABA techniques at home, reinforcing the child’s progress. Additionally, social skills training focuses on improving peer interactions, often through group sessions. These services work together to improve both daily functioning and social adaptability.

In this article, we explain in detail how to get ABA therapy via Medicaid in Indiana.

Eligibility Requirements

To receive ABA coverage under Medicaid in Indiana, there are several criteria which need to be met, including the following:

Medicaid Enrollment

The individual must be enrolled in either Indiana Medicaid or the state’s Children’s Health Insurance Program (CHIP).

Diagnosis of Autism or Related Disorder

A diagnosis from a licensed healthcare provider for Autism or a related disorder that would benefit from ABA therapy is required. A variety of professionals can diagnose autism.

Medical Necessity

For ABA therapy to be covered, Indiana Medicaid requires the service to be deemed medically necessary for the individual. This is determined by evaluations conducted by healthcare providers, who will assess whether ABA therapy could improve behavior, communication, social skills etc.

Age Requirement

Indiana Medicaid generally provides coverage for children and young adults up to a certain age, although most ABA therapy services are focused on early intervention. Furthermore, coverage may be limited to individuals under 21 years old, though services for older individuals can be considered if medically necessary.

Prior Authorization

In most cases, ABA therapy requires prior authorization from Medicaid. This means that the provider must submit detailed documentation outlining the individual’s diagnosis, treatment plan, and the anticipated benefits of therapy to obtain approval before services can begin.

Qualified Providers

ABA therapy must be provided by a qualified professional, such as a Board-Certified Behavior Analyst (BCBA) or a registered behavior technician (RBT), under supervision of a BCBA​.

Application Process

Indiana medicaid ABA therapy

The first step in applying for ABA therapy is to ensure that the individual is eligible for Indiana Medicaid.

Eligibility Criteria: Medicaid or the Children’s Health Insurance Program (CHIP) is based on factors like family income, age, and disability status. To apply for Medicaid, you can use a number of methods:

  • Online: Apply via the FSSA Benefits Portal: Indiana FSSA Benefits Portal.

  • By Phone: Call 1-800-403-0864 to apply or get more information.

  • In-Person: Visit your local Division of Family Resources (DFR) office.

  • For Medicaid Enrollment: Apply online at the Indiana FSSA Benefits Portal, by phone at 1-800-403-0864, or in person at a DFR office.

After registering with Indiana Medicaid, the next step is to obtain a diagnosis of ASD or a related developmental disorder. To do this, obtain a diagnosis from a licensed professional and keep a copy of the official diagnosis report. This will be necessary for prior authorization.

Once you have a formal diagnosis, you’ll need a referral for ABA therapy. The diagnosing doctor, developmental specialist, or primary care physician can issue a referral stating the medical necessity of ABA therapy based on the diagnosis.

Visit the Indiana Medicaid website or contact Indiana FSSA for a list of credentialed providers. Indiana Medicaid only covers services provided by licensed providers such as BCBAs or Registered Behavior Technicians under BCBA supervision. Your referral provider may also help you connect with qualified ABA therapists.

Before ABA therapy can begin, a prior authorization (PA) request must be submitted to Indiana Medicaid by your ABA provider. The PA includes diagnosis documentation, a detailed treatment plan outlining goals, therapy duration, and expected outcomes, and information on the number of hours per week needed for therapy.

The prior authorization will be reviewed to determine whether ABA therapy is medically necessary and whether it meets Medicaid’s criteria. Your ABA provider submits the request for prior authorization through Indiana Medicaid’s provider system. Your ABA provider will notify you once the prior authorization is approved, and therapy can begin.

Understanding the Benefits & Out-of-Pocket Costs

There is no limit on the number of ABA therapy hours covered per week, but the number of hours approved will depend on the individual’s treatment plan and medical necessity.

Most children with autism who require ABA therapy typically receive between 10 to 40 hours of therapy per week, based on the severity of symptoms and the goals outlined in the treatment plan.

Indiana Medicaid covers ABA therapy for long-term treatment as long as it is deemed medically necessary. The therapy can continue over several years but is generally reassessed after a certain period, often every 6 to 12 months, to ensure progress is being made and that continued therapy is beneficial. Reassessments involve updated treatment plans and progress reports from the provider to extend authorization for ongoing therapy.

Families enrolled in Indiana Medicaid can expect little to no financial burden when accessing ABA therapy for their children, with the potential for minor co-pays in some cases. Coverage is not based solely on a fixed number of hours or months but rather on whether the therapy is medically necessary to improve behavioral outcomes. The therapy’s goals must address specific challenges like communication, social skills, and problematic behaviors. Medicaid assesses the appropriateness of the therapy duration and intensity as part of the prior authorization process.​

For most children and young adults covered under traditional Medicaid, ABA therapy is typically covered with no co-pays or out-of-pocket expenses. Medicaid ensures that essential services, including ABA therapy, are provided at little to no cost for low-income families.

Some families enrolled in CHIP might face minimal co-pays depending on their income level. Co-pays under CHIP are usually very low and capped, so families should check their specific plan. For example, co-pays might range between $3 to $5 for specific services but can vary based on the family’s income and eligibility group.

Challenges and Limitations

Navigating Medicaid’s system can be difficult for families, especially when dealing with the paperwork involved in applying for services like ABA therapy. Understanding the requirements for diagnosis, referrals, and prior authorization can be challenging, particularly for families who are new to the process or have limited support.​

The prior authorization process required by Indiana Medicaid can be time-consuming. Families must submit detailed documentation, including diagnostic reports and treatment plans, to prove medical necessity. This can lead to delays in the start of therapy, particularly if there are errors in paperwork or incomplete submissions.

Indiana Medicaid only covers ABA therapy delivered by licensed professionals such as BCBAs. In rural areas, the availability of qualified ABA providers may be limited, making it harder for families to access care. Furthermore, some providers may not be enrolled with Medicaid, limiting the options for families who are reliant on Medicaid for coverage. Even if providers are qualified, families may face difficulties if those providers do not accept Medicaid reimbursement rates, forcing them to seek other options.

The reimbursement rates set by Indiana Medicaid for ABA therapy services have been a point of contention. Some providers claim that these rates do not fully cover the cost of delivering care, which may lead to fewer available providers or limited therapy hours. As a result, families might experience limited access to high-quality care or longer wait times due to provider capacity issues.​

Coverage is based on medical necessity, meaning the therapy must demonstrate improvements in behavior, communication, and daily living skills, and coverage can be reduced or discontinued if therapy is no longer deemed necessary. Periodic reassessments (typically every 6 to 12 months) ensure continued eligibility, and therapy may be reduced if progress plateaus.

Another challenge concerns coverage for young adults. Coverage primarily targets individuals under 21 years old, though it can extend to adults if still necessary. Furthermore, ABA providers must be Medicaid-enrolled, and low reimbursement rates may limit available providers. Medicaid may also exclude certain non-therapy services, leaving families responsible for additional costs.

Advocacy and Additional Support

Several advocacy groups and organizations help families navigate Medicaid coverage for ABA therapy in Indiana by providing resources, legal support, and assistance:

  1. The Arc of Indiana offers guidance on Medicaid waivers and helps families connect with Medicaid-enrolled providers.

  2. Autism Society of Indiana (ASI) provides a support network to assist with Medicaid paperwork and connecting with ABA therapy providers.

  3. Family Voices Indiana helps with Medicaid applications, waivers, appeals, and understanding ABA therapy coverage.

  4. Indiana Disability Rights offers legal advocacy and helps families with Medicaid appeals and obtaining documentation for ABA therapy.

  5. Indiana Resource Center for Autism (IRCA) provides training and resources related to ABA therapy and Medicaid.

In Indiana, families have several resources and support systems available to help secure ABA therapy and navigate Medicaid:

  1. Indiana Medicaid Waiver Program: Offers waivers like the Family Supports Waiver (FSW) and Community Integration and Habilitation Waiver (CIH) to fund ABA therapy and other services.

  2. Indiana Family to Family (INF2F): A family-led group that provides guidance on Medicaid and ABA therapy and connects families with peer support networks.

  3. School-Based ABA Services: Schools provide ABA therapy through Individualized Education Programs (IEPs)and Behavior Intervention Plans (BIPs) under IDEA.

Real-Life Experiences

Indiana-medicaid-aba2

Families in Indiana have shared a range of experiences navigating Medicaid to access ABA therapy for their children.

Many report positive outcomes despite the system’s complexities, while others face significant challenges. Natasha Virgil, a mother from Westfield, Indiana, found ABA therapy to be transformative for her 6-year-old son, Elijah. Before starting therapy, Elijah struggled to engage in activities outside their home, but ABA therapy helped him improve communication and behaviour, allowing him to participate better in daily life. Natasha expressed that without ABA, her son’s ability to adapt and live independently would have been much more difficult.

On the other hand, some families have struggled with Medicaid reimbursement cuts, which threaten access to these services. Chanel McClure, whose son King was nonverbal when he began ABA therapy, was anxious about potential disruptions to therapy due to policy changes. King has shown significant improvements since starting ABA, including better communication and social interaction, and Chanel worries about how reduced funding might affect his continued progress.

Final Thoughts

In summary, while Indiana’s Medicaid coverage for ABA therapy offers significant potential, families must stay proactive, leverage available support systems, and remain vigilant about policy changes to maintain consistent access to essential services.​
