Such nonsense. The entirety of their plans DOES NOT cover every doctor. Tell some people with immune deficiencies who use specialty pharmacies that Obamacare is an option for them.Uh, you can.
You simply need to purchase the plan that your doctor is "in network" for.
I had to change doctors 2x when I was employed with United Health as our coverage network, when the clinic I went to changed who they worked with.
Work plan didn't enable me to get insurance with "any carrier", and hospitals/networks often adjust who's network they will sign contracts with.
ACA was no different in that respect to company-subsidized plans.
