Medicaid MCO appeal

Cite: 42 CFR 438 Subpart F

Medicaid Managed Care Organization (MCO) denials are governed by federal Medicaid regulations and your state's Medicaid program rules. You have 60 days from the notice of action to file an internal appeal with the MCO. If the MCO upholds, you can request a state fair hearing — and importantly, you can request "aid pending appeal" (continued coverage during the review) if the appeal is filed within 10 days of the action.

## Molina Healthcare Step-Therapy Denial for ABA: How to Appeal

A step-therapy denial from Molina Healthcare for Applied Behavior Analysis (ABA) for Autism Spectrum Disorder (ASD) means Molina's coverage policy requires documentation that one or more other interventions were tried and found insufficient before ABA will be authorized. For ASD, this type of requirement is clinically problematic and legally vulnerable under federal parity law.

### Why This Denial Happens

Molina's ABA coverage criteria may include a requirement that patients first attempt less intensive behavioral or educational interventions — such as parent training, school-based services, or lower-intensity therapies. When the treating provider requests ABA without documenting that required prior steps have been attempted, or when the prior steps are deemed insufficient by Molina, a step-therapy denial results.

### Why It Is Appealable

Clinical individualization: ASD is a heterogeneous condition. The appropriate treatment intensity for a given patient is determined by individualized assessment, not a uniform stepped protocol. Clinical guidelines from recognized organizations such as the American Academy of Pediatrics and relevant behavioral health specialty societies support individualizing treatment based on the patient's specific presentation, not requiring all patients to fail lower-intensity steps first.

Mental Health Parity (MHPAEA): Molina cannot apply step-therapy requirements to ABA that are more restrictive than requirements applied to analogous medical/surgical benefits. If Molina does not require patients to fail lower-intensity physical rehabilitation before approving intensive PT, a parallel ABA step-therapy requirement may be an unlawful parity violation. Request Molina's NQTL analysis in writing.

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 the denial date. Expedited review is available when delay would harm the patient's health or development.

### The Appeal Process

1. Obtain the complete denial and criteria — Molina must identify each required prior step and the clinical basis for the requirement. 2. Level 1 internal appeal — file within the deadline stated in the denial notice. Molina must decide within 30 days (standard) or 72 hours (expedited). 3. Level 2 internal appeal if Level 1 is denied. 4. External review through a certified IRO — step-therapy requirements for ABA frequently fail independent clinical review when the treating BCBA provides individualized clinical justification. 5. MHPAEA parity complaint — file simultaneously with the state insurance commissioner or DOL if the step-therapy requirement appears more restrictive than analogous medical/surgical standards.

### Documentation to Gather

ASD diagnosis confirmation — formal diagnostic report with evaluator credentials.
Prior intervention history — dates, providers, and documented outcomes for any behavioral, educational, or therapeutic interventions already attempted.
Clinical rationale for ABA without further steps — detailed letter from the treating BCBA and supervising physician explaining why the prescribed ABA intensity is clinically appropriate for this individual patient, and why further step-therapy is either clinically inappropriate, already satisfied, or contraindicated given the patient's presentation.
Current functional assessment — documenting severity of deficits and specific treatment targets.
Parity request — formal written request for Molina's NQTL analysis comparing step-therapy requirements across ABA and analogous medical/surgical benefits.

### Criteria-Mapping Structure

Obtain Molina's ABA step-therapy policy. Build a response table:

| Required Prior Step | Documentation That Step Is Met or Inapplicable | |---|---| | Prior intervention X attempted | [Provider name, dates, outcome notes] | | Prior intervention X documented as insufficient | [Clinical notes with outcome data] | | ABA clinically appropriate given patient's presentation | [BCBA individualization letter + assessment] | | ASD diagnosis confirmed | [Diagnostic report] |

The strongest step-therapy appeals argue two things simultaneously: (1) the required prior steps have in fact been tried, or are clinically inappropriate for this patient, and (2) the step-therapy requirement itself is an unlawful parity violation. Both arguments together significantly increase the probability of reversal.

Next steps

Look at the date on the "notice of action" — the 60-day clock starts there.
If you file within 10 days, request "aid pending appeal" to keep coverage during the review.
Submit the internal appeal in writing using the form on the MCO's denial letter.
If denied, request a state fair hearing — the form is on your state Medicaid agency's website.
