Texas Medicaid

Hello, just a quick question, is there a way to change my plan? This pediatrician I’m trying to see takes my insurance, but the problem is I have Texas star, that’s connected with community health choice, and they won’t take the community health choice? They are the only office that’s convenient, and I have anxiety and it’s only 5 minutes from my house. Please help me out with some information, if it helps my baby is 4 months! Thank you in advanced.
