We are par providers with regular Medicare but not with this one particular Medicare HMO. The patient is aware that we are out of network with her Medicare HMO and that she will have to pay out of pocket for her services here. We do have her sign the form acknowledging this. My question is how much we can charge her for the services? Can we charge her full price the same as all other cash patients or do we have to go by the Medicare rates? If it's the Medicare rates, do we go by the par or non-par rate?
