Insurance requesting full record from LLMD

[mommakath]

LLMD's office called today to advise me that insurance has requested my full, entire medical chart from them to see if they will pay for my initial visit (and that's 'pay' at whatever ridiculous amount they decide is r&c for out-of-network doc). They asked if I wanted them to comply since they are not a HIPPA participating provider. I have not responded one way or the other but understand this is not the norm - to ask for the entire chart. Has anyone else experienced this? I want to collect my thoughts and know my rights before I call the insurance company myself. Why would they need this?
