OK the insurance co told me they only pay for ONE pair of orthopedic inserts for difficult child's feet...in her lifetime.... hello she is 4YO and still growing. The pediatrician thought they MIGHT last 6 months. :Hot Head: Silly me wanted two pairs. After talking with the ortho that was fitting her she will probably need one pair for outside shoes and another for slippers etc in the house. She is to wear them as much as possible. The ortho that fit her said he would do a letter of necessity for 2 pair. Any experience with working with insurance co's on this. They told me we would have to submit next time she needs them and see if they will reimburse. for gosh sakes..
