The many accepted insurance plans are listed on the TV Health website:
Accepted Insurance by The Villages Health
It seems to me that it would be misrepresentation to tell consumers UHC is the only one accepted by the TVHealth system clinics.
If you are told that, I would contact the state insurance department that regulates the insurance industry and trade practices.
Seeing the banner "The Medicare Store" on these United Healthcare offices in TV bothers me a lot.
In the past, all insurance mailings and advertising had to have
disclaimers saying this was not a U.S. government Medicare office or product.
This store name sounds fishy to me.
