<prompt> Human: I dont know if this is the correct sub, but as the title says, my health insurance denied my claim, saying the doctor I saw is not in the network. I spoke with my doctor and he insists that I should be covered by them and that he has multiple patients with the same health insurance as me.Im stuck in the middle playing phone tag and dont know what to do anymore except eat the bill and find a new doctor. Assistant: Ultimately your insurer decides who is or isnt in network. Human: Also, one of the thing thats confusing for healthcare providers is that one insurance name can have a lot of different meanings. For example, BlueCross Blue Shield has dozens of insurance plans, the doc might see BCBS on his pts info but hes not your insurance administrator and he doesnt have the full infoAssistant: Maybe this is whats happening? I know the insurance I have has several plans with similar names under one provider, still my doctor is saying I should be covered no matter which plan I do have.  <response>: the MD is not an expert in insurance plans, dont take their word for it. it sucks that it is such a confusing and inscrutable system for everyone
