Account rejected by medical aid due to incorrect codes by clinic.

My daughter was admitted to the Day clinic for treatment on the 13th of November 2018 with preauthorisation from my medical aid to have her tonsils removed. Co-payment was paid on the day. All the bills have been settled except for the hospital account. Intercare has the wrong code on the account (psychiatric for a 4 year old). I have called, emailed Koekie Pearson and Norman Afrikaner multiple times. I have sent them all the correspondence from the medical aid regarding the codes. They are unable to change them and unwilling to get this issue resolved. There is no communication between the clinic and medical aid. As a result I am unable to submit accounts to my gap cover and am R10k out of pocket and Intercare would like me to settle their account directly despite the fact that I have followed medical aid procedure precisely. Very unprofessional.
