Doctor's can be such idiots...
I am from Kentucky also. Just a little south of were you are. I go to Lexington at the "Kentucky Diabetes and Endocrinology Center." I see Dr. Wendell Miers. I really like him. He prescribed Glucophage immedietely upon looking over my test results...and I'm not trying to conceive. He is very accessible. I have emailed him several times with questions and concerns and he has always gotten back with me. I know it's a little bit of a drive but I think it's well worth it.

Under "Administration" it gives just a few of there insurance carriers they accept.
"Insurance Carriers
Our physicians are participating providers for Medicare, Medicaid, Anthem BCBS, CHA Health, UHC (United Health) and Bluegrass Family Health, among others. Our staff will be happy to advise you of our provider status with your particular insurance carrier. "
I hope that Anthem BCBS is what your sisters insurance is.
If you have any questions or need more information please let me know.
