Key takeaways

  • Eligibility requires a diagnosis of autism spectrum disorder and demonstrated need for a level of care typically provided in a hospital or skilled nursing facility.
  • The waiver covers medically necessary ABA services including assessment, treatment planning, direct therapy, and caregiver training.
  • Apply through your county's Department of Human Services; wait times vary but can be several months.

What Is the Colorado HCBS Waiver for Autism?

The Home and Community-Based Services (HCBS) waiver is a Medicaid program that allows families to receive funding for long-term care and support services in their home and community rather than in an institution. For autistic children, Colorado's children's HCBS waiver (often called the Children's HCBS Waiver) can cover applied behavior analysis (ABA) therapy. This waiver is administered by Health First Colorado (Colorado's Medicaid program) and is available to children under 21 who meet specific medical and financial criteria.

ABA therapy is a scientifically proven intervention that helps autistic individuals develop communication, social, and daily living skills. The HCBS waiver covers ABA when it is deemed medically necessary by a qualified professional. Without the waiver, families would have to pay out-of-pocket or rely on private insurance. The waiver removes a major cost barrier.

Who Is Eligible for the HCBS Waiver for ABA?

Medical Eligibility

To qualify, a child must have a documented diagnosis of autism spectrum disorder (ASD) from a qualified professional (e.g., a developmental pediatrician, psychologist, or board-certified behavior analyst). The child must also demonstrate a need for a "hospital level of care" or "skilled nursing facility level of care" - meaning their condition requires the kind of intensive support that would normally be provided in an institutional setting, even though they can safely remain at home with the right services.

Financial Eligibility

Families must meet Colorado's Medicaid income and asset limits. However, Colorado has a "Medically Needy" spend-down option for families whose income is above the standard threshold. Additionally, children who qualify for Supplemental Security Income (SSI) automatically meet the financial criteria. For detailed income guidelines, contact your local county Department of Human Services.

Residency and Age

The child must be a resident of Colorado and under 21 years old. Once a child turns 21, they may transition to an adult waiver or other adult Medicaid benefits.

What Services Does the HCBS Waiver Cover for Autism?

The HCBS waiver covers a range of services designed to support the child at home and in the community. For ABA specifically, covered services typically include:

  • ABA assessments - functional behavior assessments and treatment plan development
  • Direct ABA therapy - one-on-one sessions with a registered behavior technician (RBT) supervised by a board-certified behavior analyst (BCBA)
  • Caregiver training - teaching parents and guardians how to implement behavior strategies in daily routines
  • Behavioral monitoring and supervision - ongoing oversight by the BCBA to adjust the treatment plan

Other waiver services may include respite care, personal care, occupational therapy, speech therapy, and assistive technology - all of which can complement ABA. The exact services authorized depend on the child's individual needs as determined by the case manager and an assessment team.

How to Apply for Colorado's HCBS Waiver for Autism ABA Therapy

Step 1: Get a Diagnosis and Medical Recommendation

Start by obtaining a formal autism diagnosis from a qualified provider. Ask the diagnosing provider to write a letter of medical necessity for ABA therapy. This documentation is essential for the waiver application.

Step 2: Contact Your County Department of Human Services

Each county handles HCBS waiver applications. Visit your county's human services office or website to express interest in the Children's HCBS Waiver. They will schedule an intake appointment and assess financial eligibility.

Step 3: Complete a Level of Care Assessment

A case manager will conduct a standardized assessment to determine if your child meets the "level of care" requirement. This evaluation reviews the child's functional limitations, medical needs, and support requirements. Be prepared to share reports from doctors, therapists, and school staff.

Step 4: Submit the Application and Wait for Approval

After completing the assessment, the county will forward your application to the state for final review. Approval can take several weeks to several months depending on the current waitlist and processing times. Colorado sometimes has a waitlist for the HCBS waiver; families should apply as early as possible.

Step 5: Choose a Provider and Start Services

Once approved, you'll receive a notice of eligibility and a budget of waiver funds. You can then select an ABA provider who accepts Medicaid and the HCBS waiver. Our free matching service at Local ABA Therapy can help you quickly connect with vetted, BCBA-led providers in your area who accept the waiver.

Common Mistakes to Avoid When Applying for the HCBS Waiver

  • Waiting until you need services urgently. The application process can take months. Apply as soon as you suspect your child may qualify, even if ABA services aren't yet immediately needed.
  • Not providing enough medical documentation. A letter of medical necessity from a doctor along with detailed reports from therapists strengthens your case. Request copies of all assessments, IEPs, and progress notes.
  • Assuming the waiver only covers ABA. The waiver covers many other supports like respite, personal care, and therapies. Ask your case manager about using any unused funds for complementary services.
  • Not checking whether providers accept the waiver. Not all ABA providers accept Medicaid or the HCBS waiver. Use our free matching service to find ones that do - we verify insurance and waiver acceptance upfront.
  • Forgetting to reapply if your child's condition changes. Waiver eligibility is reviewed annually. If your child's needs increase, you can request a reassessment to adjust the service plan.
