You might want to change your Medicare Advantage insurance to traditional Medicare. That will give you more provider options. Provider options may be important down the road. I read that more and more health systems are refusing to see many, if not most, Medicare Advantage patients. There are exceptions given for some in state plans that negotiate higher payments to desired providers like Mayo. Overall, providers claim that Medicare Advantage plans pay poorly, delay approvals for needed procedures, and delay payments. There are lawsuits and many complaints filed with CMS. Many patients are not aware of these problems until (like you) they find a provider will not accept their insurance.
