Rejected entire hospital and stepdown claim in-spite of approvals given

I honestly don’t know how Discovery Health Medical Aid manages to keep their clients when they reject claims that they gave approval for, I see so many of these complaints it seems to be a trend of Discovery to reject as many claims as they can. Why do you cause your client so much distress? We got all the necessary approvals and got an email confirming it, however the claims department rejects the entire hospital bill of R163,158.68 in spite of all the correct approvals and visits by Discovery consultants to check in etc… Netcare Milpark say they did apply and get approval, I see emails approving but it gets rejected…Code 133 and code 50022: “We have not paid this amount as we had not approved cover for this code”. The Hospital admin say they did request approval and get it…!?! What game are you playing? Same thing with the Stepdown facility, got all the approvals and all the correct codes etc plus the confirmation email from Discovery only to reject the entire amount of R 25,398.18 – code 133 again. The facility say they submitted it as per the approval… What is going on… My mom was in hospital because of heart problems, chest pains but I think you are trying to kill her off by stressing her out like this…Your service is utterly disgusting!!!
