Yep, every surgery I've had so far has had a pathology line item. Honestly, better safe than sorry there. My uterus and friends came out looking really rough (they gave me pics), and I was calling every day after the fact waiting for the pathology report to come back. Thankfully they found nothing wrong with it, but still. Glad to know they require the testing.
I would get in touch with Garramone's office and let him know that you felt a bit deceived about this bill not being included in your costs and how long you had been saving. Best case scenario, his office takes care of it for you. Worst case scenario, they don't but they start making a note about it in the new patient paperwork so other guys aren't surprised by it.
