Yes, your Insurance company is quite right. You need to produce all the medical history documents of your wife to the US doctor who provides his/ her services under the said insurance company. They will evaluate that it is really a case of secondary infertility
and advise if the same treatment has to be continued or something else which would be better than this can be done. I am saying this because an Endocrinologist
experienced in PCOS
and an infertility specialist or OB doctor are involved in such cases and they will see the need of her undergoing this particular treament. So be prepared that they might try to simply regulate her menstruation
and hence ovulation first and then would take other steps if ovulation is not happening properly. So it will be done very much systematically and you do not need to worry even though they do not follow the same course what she is undergoing right now. I hope you got your answer. All the best.
