I heard you can join for $10. Per mo th if you have Medicare. Is this correct?

You should call to find out and they would be able to tell you. I know they do have a discount program based on Income.

Seniors have $48/month fee at the Independent Health branch

I was told only "Silver Sneakers" get the discount but if you have another major health insurance along with Medicare yes ... But they may not tell because they want the fast money
