Frustrated by non resolution of query

Discovery Health approved a very expensive injection for my son who was born premature for a period of four months. Discovery Homecare called me and said I had approval for a nurse to come to my house to administer these injections as it would prevent exposure to other illness's if he didn't have to go to the hospital.<br> I have got approval codes and authorisation letters for all of this.<br> Discovery Homecare has now put in the claims and Discovery health has rejected the claims. I have spoken to several people in this regard who have told me the problem is solved or will be resolved within the day and it has now been 2 weeks.<br> Apparently the issue is that Discovery Homecare is using the wrong codes to claim from Discovery Health. I am getting incredibly fed up.<br> I believe this is poor performance on the part of Discovery! I have called the call centre four times now with no joy!<br>
