Eligibility Requirements for Mo HealthNet ABA Coverage

Who Qualifies?

To receive ABA therapy through Mo HealthNet, your child must meet several criteria:

  • Age: Under 21 years old.
  • Diagnosis: A formal diagnosis of autism spectrum disorder (ASD) from a qualified professional, such as a developmental pediatrician, psychologist, or psychiatrist.
  • Medical Necessity: A doctor must prescribe ABA therapy as medically necessary, typically based on a comprehensive evaluation.
  • Enrollment: Your child must be enrolled in Mo HealthNet. If not already enrolled, you can apply through the Missouri Department of Social Services.

How to Get a Diagnosis

If your child does not yet have an autism diagnosis, start by talking to your pediatrician. They can refer you to a specialist for a diagnostic evaluation. Many hospitals and clinics in Missouri offer these assessments, though wait times can vary. Early diagnosis is crucial because it opens the door to early intervention services, which are often more effective.

Step-by-Step: How to Start ABA Therapy with Mo HealthNet

Step 1: Confirm Your Child's Mo HealthNet Coverage

First, ensure your child is enrolled in Mo HealthNet. You can check your coverage online through the Missouri Department of Social Services portal or call their customer service line. If you're not enrolled, you can apply online or at your local Family Support Division office.

Step 2: Obtain a Prescription for ABA Therapy

Your child's doctor must write a prescription for ABA therapy. This prescription should include the diagnosis and a statement that ABA is medically necessary. Keep a copy for your records and to share with potential providers.

Step 3: Find a BCBA-Led Provider That Accepts Mo HealthNet

Not all ABA providers accept Mo HealthNet, so it's important to find one that does. You can search online or ask your doctor for recommendations. A free service like Start with ABA can match you with vetted, BCBA-led providers in your area who accept Mo HealthNet, saving you time and effort.

Step 4: Schedule an Initial Assessment

Once you've found a provider, they will schedule an initial assessment with a BCBA. This assessment evaluates your child's strengths and challenges and forms the basis of a personalized treatment plan. The provider will then submit a treatment plan to Mo HealthNet for approval.

Step 5: Begin Therapy and Monitor Progress

After approval, therapy can begin. Sessions are typically held in a clinic, at home, or in the community, depending on your child's needs. The BCBA will supervise the therapy and adjust the plan as needed. Regular progress reports are shared with you and your child's doctor.
