Hospital authorization system flawed

I was recently booked for a hospital procedure where I duly contacted discovery for authorisation. I was given the necessary authorization for the specific procedure and doctor. But to my astonishment, Disvovery did not pay even half the bill. After 3 weeks of calling in at the call centre with promises of being called back, I was finally informed that even though the hospital is covered in my network, the operating doctor is allowed to charge above scheme rate. Why did Discovery suggest him in the first place knowing he is not part of the network, furthermore I strongly believe that it is misleading to suggest that I gave consent to this as I was of the opinion that since the doctor is authorised, then surely I will be covered. Why recommend that hospital in yhe first place, I was already at another hospital and had to drive across town to the suggested hospital that Discovery <br> <br> It is disheartening that after 3 years with the scheme and on my first hospitalisation in that period, Discovery cannot even pay half of my bill and I have to pay over R6000 off my pocket. Its a shame we only become wiser after the fact, or should I say after tge invoice. Cant wait till year end
