My wife and I are over 65 and have been getting calls saying that they were recommended by our medical insurance company. They want to make an appointment to come to our home for an evaluation. I, being very conscious of scams cheating the older generation, told them of our requirements to accept a visit.
They will have to call our primary care doctor at our medical clinic. I did not tell them who either of them were. If they work with our insurance company they should be able to get those names.
Then our clinic would have to call us to say that it would be OK for them to visit our home. I also told them that there would be an hourly fee. This is our house and our rules.
So far no calls.
