Is there any way I can get Fidelis to use a specific agency? The agency does not have a contract with Fidelis but is willing to work with them.

If Fidelis does not have a contract with the provider you want, then they won’t provide services at contract rate reimbursement. You probably have to stay within their network or pay out of pocket. 
It’s very important to review services provided before you sign with a insurance or such provider like Fidelis so there are no surprises like this. 

Just read more and found they are really a Middle man with insurances and services.

What I read on the internet they r an insurance company. Like any insurance company I assume they have contracts with certain transport companies? Also certain care agencies. Do u have an Office of Aging in your County. Maybe they can help you or even find you transportation and help. If low income maybe Medicaid can help.

yes fidelis is supposed to supply transportation to and from Dr"s appointments and that ispoor, get help from health care agencies for help with my husband in mornings 20 hrs week no help the pca comes foe a week or 2 and then no more. I usually have doctors appointments from blood dr, gp, foot dr. cardiologist endocrinologist. physical therapy .I have a compressed lumbar spine hip waiting for surgery and leukemia.

Is fidelis an insurance company? Where are you going in the morning?
