Are these doctors refusing to treat patients with Medicare AND supplemental insurance or those patients with ONLY Medicare?

When I signed up for medicare, I was told that a secondary provider was not optional, I had to have one. My primary provider became my secondary provider.

When I signed up for Medicare in 2010, there was no mention whatever of a secondary provider. My primary did become my secondary,but by my choice. I could have just as easily dropped it.
