Thank you both for your kindness. I have pursued this issue with insurance as much as I can tolerate. Ive been working on this for well over a year, and hitting a brick wall every way I turn. I will pay this debt off by making payments a little at a time until it’s done. My credit rating and good reputation of paying my bills is valuable to me. I posted here to see if others have had similar experiences. Plus a warning to other readers of what has happen to me in this situation. I am very grateful for the availability of mammaprint from Agendia. This test saved me from needing to go through the struggles of chemotherapy. Just because the hospitals and physicians we work with are within our preferred list with insurance, it doesn’t mean that lab work and other testing they prescribe is also covered. Nor is it necessarily the physicians responsibility to check each patients insurance coverage. We must ask questions and advocate for ourselves in medical procedures. But as I said in my original post, the cost is a bitter pill to swallow! Hoping my experience can be beneficial to others as they pursue the best treatments for themselves.
