Kids Medicaid health plan options- how do you decide?

We are transplants from out of state to the Atlanta area, & my preteen son was finally approved for Medicaid. Now we have to choose between Peach tree, Amerigroup, & Caresource. They all sound fairly comparable. (Tho I’ve heard Amerigroup should be avoided?)

If we had a preferred doctor already, we would choose the one they accept.. Tbh I’ve been searching & can’t seem to find enough info about any of the doctors online to choose one over any of the others. (For reference, we are in North Atlanta- Brookhaven, chamblee area.)

Would greatly appreciate any input on which plans are preferable or which to avoid… and any recommendations for a good pcp for an adolescent boy in the area as well. (He’s healthy, no severe health issues, ADHD/ASD, but really struggling with depression & anxiety since moving so also looking for a good therapist, preferably male.) so any suggestions there welcome also. Thanks in advance!
