We signed up for a United Healthcare plan a couple years back. It showed a bunch of Doctors in network. Once we were on the plan, 90%+ of the Doctors told us they didn't accept United Healthcare or weren't accepting new patients. We couldn't find quality Doctors near us as a result. Ended up having to switch off United Healthcares plan as a result. Certainly felt like it was false advertising to say all the Dr's are in network just to find out none of them will treat you.
