Have you been in touch with the American Cancer Society? If they can't directly help, they can put you in touch with CancerCare or some other organization who may be able to help you out with some of your treatment bills. Ask for legal assistance too if necessary, they are there to help. Please make a few phone calls or speak with a social worker and see if you can get some assistance. I think too that you might want to explain your situation to your onc, doctors really don't know what goes on with their patients' billing, I would sure think and hope he would be understanding, I know my onc would be. Another thought, if you are getting chemo at your onc's office, it might be better to get it at a hospital or cancer center instead, they are usually more professional and better able to deal with these types of billing issues. Take a deep breath, get a good night's sleep and keep fighting, it's stupid, aggravating, insulting, stressful bs, but it's necessary sometimes unfortunately. Good luck!
