Well, today insurance has found my oncologist, thanks largely to the persistence of the medical administrator from my clinic. Apparently my doctor's fairly new at the clinic, and it takes a long
time for the provider lists to update. Perhaps their computers are coal-fired.
I've been warned it may be a month or more before claims for her services will be properly covered, but I've also been assured by both the clinic and the insurance company that once the system is straightened out everything will be rebilled dating back to my first visit with her.
So a large hassle is now a small hassle. And we soldier bravely on.
