I work for a treatment program in the greater Philadelphia area. I recommend you check the box for Keystone 1st. They have the most thorough coverage for long term health and mental care (including meds). You should know that your mental health coverage (including and addiction treatment if needed) will be managed through CCBH (Community Carw Behavioral Health), and all PA Medicaid is capitated to the local county where you reside -- your provider(s) have to accept Medicaid for your county of residence. In other words, you could live in Delaware County on the County line and seek care at a clinic close by, but in a different county, like Montgomery. If your Montgomery County provider doesn't take Delaware County Medicaid, you will have to pay out of pocket (or seek care elsewhere). You should be able to do a search ahead of time for providers through the CCBH website. Good luck! Welcome to PA (soon).
