I'm sure my RD knows how to do this, but it will help me to be prepared for my next visit. She is prescribing A new water therapy tub, the walk in kind. My insurance is BCBS of NC. I called them to find out how that works....It has to be a medical need and not a convenience need. My question is has anyone been through this or have tips for me to work it out? I really need it..... My muscles start contracting and everything if I don't get it everyday. I've got a jetted tub but its too low and only 1 speed for the jets HARD!!!
