Does Medicaid Cover ABA in Aurora? Health First Colorado

Does Health First Colorado cover ABA therapy in Aurora? Yes, for children and young adults 20 and younger, when the therapy is medically necessary and approved ahead of time. The rules around that approval are changing in the next few months, so this guide covers what is in force now and what is coming.

How do I get ABA approved by Medicaid?

HCPF calls the benefit Pediatric Behavioral Therapy, or PBT. The steps run in this order:

1. You choose a provider that is enrolled with Health First Colorado.
2. The provider assesses your child and writes a treatment plan.
3. The provider submits a prior authorization request (PAR) to the state’s utilization management vendor.
4. A reviewer decides whether the service is medically necessary. You and the provider both get a letter with the decision.
5. If approved, the letter says how many hours are authorized. The approval lasts up to six months. After that, the provider files a new request.

Per HCPF’s provider page, the PAR must include a standardized, norm-referenced assessment of adaptive behavior completed by the behavioral therapy provider, a referral for services and the plan of care. For members under 21, reviews follow federal EPSDT rules, which look at what your individual child needs.

Services do not start until the approval is in place. Ask any provider how long they expect that step to take. Do not accept a promised date you cannot check.

Does my child need an autism diagnosis?

Today, no. HCPF’s member page says behavioral therapy is available to all children enrolled in Health First Colorado when it is medically necessary, and it does not require an autism diagnosis.

That may change. The draft permanent rule (Section 8.281) lists the eligibility conditions HCPF is proposing. A member would need to be under 21 and enrolled, with a documented qualifying diagnosis, such as autism, developmental delay or intellectual disability, or be under 3 and at risk for delay. The member would also need a documented recommendation for PBT that came out of a diagnostic evaluation. HCPF’s draft rule update is a draft, not law. If you are still waiting on an evaluation, see our guide to autism evaluations in Aurora and the one on ABA without a diagnosis.

What changes on December 1, 2026?

HCPF’s Policy Memo PM 26-003 says requests submitted on or after December 1, 2026 will be reviewed with InterQual Applied Behavior Analysis Treatment criteria. The state-developed criteria will retire. Requests submitted before that date keep the criteria in effect when they were filed.

The memo draws three limits you should know about:

• It replaces the clinical review criteria only. It does not change the benefit, provider qualifications or billing rules.
• It does not override EPSDT. For members under 21, failing the InterQual criteria does not by itself mean the service is not medically necessary. The reviewer must consider your child’s individual circumstances before an adverse decision.
• Denials still go through the same options: reconsideration, peer-to-peer review and member appeal.

In practice, expect providers to document more closely. Ask your provider how they are preparing for the new criteria.

What happens if the request is denied?

HCPF’s member page says the doctor who requested the PAR is called for a peer-to-peer review before a denial or partial denial. If the PAR is still denied, your provider can ask for a reconsideration, which a different doctor reviews. The provider can also submit a new PAR with more medical information.

You can also appeal in writing to the Office of Administrative Courts. Your letter of appeal must arrive within 30 calendar days of the date on the denial notice. Include your name, address, phone number, Health First Colorado ID and a copy of the front page of the notice.

How did the October 2025 rate cuts affect ABA providers?

HCPF’s budget reductions fact sheet says payment rates for pediatric behavioral therapy were reset to 95 percent of an updated multi-state benchmark, effective October 1, 2025. The department’s Q&A lists PBT among the services affected.

Providers and the state describe the cause differently. Colorado Public Radio reported that the Medicaid director pointed to private equity in the field, minimum-hour enrollment rules and billing for non-therapeutic time such as naps. A provider-group representative told the station that the state created the cost problem and is using it to justify cutting therapy. You do not have to settle that argument. You do need to ask any clinic whether it is currently accepting Medicaid clients and how it handles new authorizations.

HCPF also began rulemaking after a July 2025 federal review found some technicians were not meeting national standards for training and supervision. The emergency rule page says staff delivering PBT must be properly trained, certified and supervised.

What is the permanent rule, and when does it start?

HCPF expects its initial reading before the Medical Services Board on December 11, 2026. The FAQ document gives March 2, 2027 as the expected effective date if the board adopts the rule. It also says approved services that run past that date stay authorized for the rest of their authorization period, and the next renewal on or after March 2, 2027 is when the new guidelines apply. Age-based hour guidelines are a part of the draft. We cover them, and why they are not caps, in how many hours of ABA per week.

What if my income is too high for Medicaid?

The Children’s Buy-In lets a family buy into Health First Colorado for a child with a disability. Your child must be under 19, have a disability that meets the Social Security Administration listings, and your family income after disregards must be under 300 percent of the federal poverty level. You do not have to apply for SSA disability.

Premiums depend on income. HCPF’s table, effective April 1, 2026, sets them at $0, $70, $90 or $120 a month. Apply through Colorado PEAK, then complete the Health First Colorado Disability Application and Medical Release Form. HCPF says the direct line to Buy-In experts is 1-800-711-6994.

Does the CES waiver cover ABA?

The Children’s Extensive Support (CES) waiver is a separate program. HCPF’s CES page says a child must be under 18, have a developmental disability or delay, live in the family home, meet an institutional level of care, and need direct human intervention for behavior or a medical condition at least once every two hours during the day. Its services include respite, assistive technology, community connectors and home adaptations. ABA is not on the waiver list. HCPF’s member page says all EPSDT services are available to children who are on a waiver, so ABA still runs through the PBT benefit.

To apply, contact your case management agency. HCPF’s directory lists Rocky Mountain Human Services as the agency for Adams County and Developmental Pathways for Arapahoe and Douglas counties. If you do not know which county you live in, ask either agency. For respite, see our respite care guide.

How do I use Medicaid for ABA at school?

HCPF’s Policy Memo PM 25-005 says Health First Colorado covers medically necessary PBT in a school setting. It also says the program no longer covers 40 hours a week of clinic services when a child has access to school hours, unless the district shows the child cannot be served in the classroom. EPSDT requests are still considered if medically necessary, but they need school information, such as an IEP, showing the total PBT hours the child gets at school. Our guide to Aurora Public Schools and Cherry Creek covers the school side.
