Gestational Diabetes

I went yesterday to a high risk doctor due to me failing both of the sugar test. They don’t accept my insurance but want me to come back and switch my insurances, I really don’t want to switch because my insurance is one of the best coverage ones. I want to cancel the appointment to go back in 2 weeks and tell my primary ob that I want to go to a different office that accepts my insurance or would it just be easier to switch my insurance?
