Aetna commercial insurance coverage
On fully-insured Aetna commercial plans, ABA therapy is covered for individuals with autism based on the state's insurance mandate. Aetna's clinical policy (CPB 0539) classifies ABA as medically necessary for autism when provided by a qualified professional such as a BCBA.
Coverage typically includes:
- Comprehensive diagnostic evaluation and functional behavior assessment
- Discrete trial training (DTT) and naturalistic teaching
- BCBA supervision and RBT/technician-delivered therapy hours
- Parent/caregiver training
- Ongoing progress monitoring and treatment plan updates
Aetna Better Health — Medicaid plans
Aetna Better Health is Aetna's Medicaid managed care division. It operates in multiple states including Virginia, Florida, Texas, Illinois, Pennsylvania, Ohio, Maryland, and others. On Aetna Better Health Medicaid plans, ABA coverage follows the same federal requirement that Medicaid must cover ABA for children under 21 with autism.
How to get prior authorization for ABA through Aetna
- Confirm ABA is covered on your specific plan by calling the member services number on your Aetna insurance card.
- Get an autism diagnosis from a licensed professional — Aetna requires this before authorizing ABA.
- Choose an Aetna in-network ABA provider using FindABA or Aetna's provider finder at aetna.com.
- Your ABA provider submits a prior authorization request — Aetna reviews within 7–14 days.
- Services begin once authorization is approved. Review the authorization letter for approved hours and dates.
What if my Aetna plan denies ABA coverage?
If Aetna denies your prior authorization, you have the right to appeal. Your provider can submit a peer-to-peer review where a BCBA speaks directly with Aetna's medical reviewer. Most denials that go to peer-to-peer review or formal appeal are overturned. If a fully-insured plan denies a state-mandated benefit, you can also file a complaint with your state insurance commissioner.
