Autism Spectrum Disorder (ASD). Retro to 1/1/16 Applied Behavioral Analysis (ABA) therapy for the treatment of ASD will no longer be an excluded benefit under our MCN plan (HMOs will follow State rules). Coverage includes medically necessary ABA therapy for ASD diagnosed by a licensed medical professional after copay (no age or # of visit limits). Claims that were denied in 2016 will automatically be reprocessed and members impacted by this will receive an updated Explanation of Benefits (EOB). A letter will be sent to anyone who called in to inquire about this benefit as well.
