We will very shortly be having to purchase supplemental insurance as we will be going on Medicare. We have pretty much decided to go with Plan F either with CBC or UH. My question would be does anyone know whether Blue Cross is accepted by more doctors than United Healthcare or vice versa. We are in PA now but hopefully in TV by late summer or early fall so I would prefer to go with the more accepted one now and not have to change once we move. Thx for any info in advance
