Denied Authorization for my daughter appointment that is urgently needed .

Took my daughter to the dermatologist last Wednesday . she was then diagnosed by the doctor as having flat warts . the Dr then prescribed a ointment (which he had fully explained ) as she is to young to have surgery to remove them . Only to be denied authorization for the payment of the ointment by Discovery Health. After calling the Client services this morning . I was asked to get letter of motivation from the Dr as to why my daughter requires the ointment and evidence /proof that my daughter has flat warts . Firstly its logically clear why the ointment us being prescribed as my daughter is too young to have such surgery . And after paying my contribution timeously like any other Client , Im being asked to provide proof that the warts really exists . How insulting to be asked for proof . Basically Discovery is insinuating that I am creating a medical condition that doesn't exist .
