My insurance company has been accepting and paying claims for several months and suddenly the identical billing code was rejected recently. I called the insurance company to find out why the claim was no longer being processed. I cited a couple claims that were covered.
The representative told me the past claims were incorrectly paid for by insurance as well, and they'll have to reprocess them and bill me for those as well.
I was stunned. Is there any recourse here? I stopped going to the doc after my claims were no longer being covered. I would have stopped much sooner had I known they wouldn't have been covered.
