Yes I have asked all the offices which insurance I should purchase but they were not familiar with the ACA plans I mentioned. I am in the process of asking the insurance company for a detailed breakdown before purchasing. Thanks.

Cigna would be great. If you have official diagnosis, the ABA is covered fully. On the other hand, it will depend on the plan detail as well.

Have you tried talking with the office staff at a therapist's office? Ask them what insurance they currently take, and any opinions about which ones have better coverage.

Got it on Healthcare.gov.

Thank you for the information. Did you purchase your insurance on Healthcare.gov or outside the marketplace? It is confusing trying to figure out which is the best option for my son. We need to purchase United Healthcare insurance since the facility we want to take him to only accepts UHC.
