I've been researching this for over a month now and see why 11 for office would seen to been correct. But a handful of codes the pathologist bills for get higher payment for the office POS. Because they assume in your office you have additional expenses (rent, equipment,....), Rather than a facitily POS were the facility itself gets separate payment. I don't want to recieve any overpayments, but I want to bill the right POS.
