Yeah. My UHC insurance requires a center of excellence rating (marketing spin for pre-negotiatied cheapest rates possible). If I go with Nicholson, I go to Presbyterian. If I go with Kim, I must go to Wise. I can also pick Baylor, UT SW, Plaza Medical center in FW, or Medical City Dallas hospital.
Btw, shortly after this post the folks from Nicholson called me two or three times. It's almost like their ears were burning! :-)
