Discovery LA Health review: They refused to pay the hospital bill

I was admitted and I was not responding to pain killers and it was an emergency, and Dr prescribed pain injection that I responded to, but they refuse to pay saying the Dr should have not prescribed it,, so my question is that what was the Dr supposed to do? Was she supposed to just watch me dire, while I pay medical aid well and they said they pay 100% when admitted, please help me to get to the bottom of this, thank you
