## Molina Healthcare: ABA Denied as Non-Formulary — What This Means and How to Appeal

A "non-formulary" denial for Applied Behavior Analysis (ABA) therapy for Autism Spectrum Disorder (ASD) is unusual, because ABA is a behavioral health service rather than a drug, and formulary classifications typically apply to medications. When Molina issues this type of denial for ABA, it generally reflects that the specific ABA service, delivery modality, or provider type is not on the plan's approved benefit list — or that the plan is treating ABA as an optional benefit rather than a covered service.

### Why This Denial Happens

Molina may issue a non-formulary or non-covered-benefit denial for ABA when: the specific ABA delivery format (e.g., telehealth, school-based, home-based) is not listed in the member's benefit schedule; the provider type (e.g., a BCBA without a supervising physician) does not match the plan's covered provider definition; or the plan's benefit booklet does not explicitly list ABA as a covered behavioral health service.

### Why It Is Appealable

Several legal frameworks bear on this type of denial:

State coverage mandates: The majority of U.S. states have enacted laws requiring health insurance coverage of ABA for ASD. If the member's plan is subject to state insurance law, a non-formulary denial may directly contradict the applicable state mandate. Verify the applicable state law for the member's plan type.

MHPAEA: If Molina covers analogous medical/surgical services (such as physical rehabilitation or skilled nursing) but excludes ABA as a behavioral health service, this may constitute a parity violation.

ACA Section 2719 / ERISA Section 503: External review and full-and-fair internal review rights apply. The external review window is approximately four months from denial.

### The Appeal Process

1. Obtain the full denial letter and benefit explanation — request the specific benefit category under which ABA was excluded and the plan's definition of covered behavioral health services. 2. Review the member's Summary of Benefits and Coverage (SBC) — confirm whether ABA appears as a covered benefit or exclusion. 3. Level 1 internal appeal — file within the deadline in the denial notice. Argue that ABA is (a) a covered behavioral health benefit under the plan, (b) required by state mandate, and/or (c) required by federal parity law. 4. Level 2 internal appeal if Level 1 fails. 5. External review through a certified IRO once internal remedies are exhausted. 6. State insurance commissioner complaint — if the denial conflicts with a state coverage mandate, a parallel regulatory complaint is appropriate.

### Documentation to Gather

• ASD diagnosis confirmation — formal diagnostic report.
• Member's benefit documents — Summary of Benefits and Coverage, Evidence of Coverage, and any rider or exclusion schedules.
• State mandate documentation — copy of the applicable state law requiring ABA coverage, if the plan is subject to state insurance regulation.
• Provider credentials — confirmation that the treating BCBA and supervising provider meet applicable licensing requirements.
• Medical-necessity letter — from the treating BCBA and physician confirming ASD diagnosis and clinical need for ABA.
• Parity request — written request for Molina's explanation of how it classifies comparable medical/surgical services under the same benefit structure.

### Criteria-Mapping Structure

| Basis for Non-Formulary Denial | Appeal Response | |---|---| | ABA not listed as covered benefit | [SBC language + state mandate citation] | | Provider type not covered | [BCBA credentials + plan's behavioral health provider definition] | | Delivery modality not covered | [Plan policy language + parity argument] | | ASD diagnosis and clinical need | [Diagnostic report + BCBA treatment plan] |

This denial type often hinges on plan document interpretation and state law — a healthcare attorney or patient advocate with insurance law experience can significantly strengthen this appeal.
