<prompt> Human: Im rehabbing my knee because Im post-op from a knee arthroscopy. My insurance covers 80 of my visits but Im out of work recovering from the surgery and money is tight, so my PT gave me a financial assistance form to fill out to see if I qualify for help.Yesterday he comes up to me and says that I can either use the 80 from my insurance or pay a custom amount he set for me per visit which would be 8 of the total cost. Every visit can range from 100-300 sometimes more depending on how hard he works me out, how long the visit is, etc. He manages the place, so I guess he sets the prices each visit.When I asked him how much I should expect to pay per visit it seemed like he was beating around the bush and wouldnt even give me an estimate. Not only that, but he also said that Im going to get a bill in the mail saying that I owe a really large sum of money for the PT, but that I should ignore that. WTF?He said that next time I come in, hell have an agreement form for me to sign. Should I refuse to sign until I can get a copy and read it over? Or should I just read it and sign? I would REALLY like to consult with somebody because I dont 100 understand what Im agreeing to or how this process works.Im desperate for the PT because without this PT, my knee situation isnt going to improve. Im being held back financially and its really frustrating trying to get my life back on track.Advice appreciated, thanks.  <response>: Its not uncommon for some doctors to give cash discounts but from what you describe it does sound a bit unethical. In my town there are lots of places to get PT, you might see if there is another in your area that is covered by your insurance.
