What can I do about doctor’s office taking me to court foroutstanding medical bills when I am still waiting on my insurer to pay?

Your insurer is putting you in a bad spot. When you get medical treatment, you agree to pay the doctor. If the insurer does not pay for any reason, including a lack of paperwork, you are obligated to pay yourself and the doctor can sue you to force payment--if the insurer was wrong to not pay, you should later be able to get reimbursement and possibly other compensation from them, but you are still yourself obligated to pay. If the doctor does not cooperate with your insurer and provide the paperwork you need for insurance coverage, it's possible you may have a cause of action against the doctor--but if sued for  nonpayment the doctor, unless you defend yourself correctly, he may still win and get a judgment against you. Caught between a doctor and the insurer, you should retain an attorney to advise and represent you. If you don't want to get one immediatlely, try first letting the insurer know that if they don't resolve this with the doctor and you are sued, you will expect them to pay our attorney fees...and forward to the doctor the correspondence from the insurer about the doctor's failure to provide paperwork and let the doctor know that if have to go to court under this circumstance, you will file an ethical complaint against the doctor and consider a countersuit. Send your letters in some way you can prove delivery; be professional in tone; and offer to both parties to assist them in resolving the dispute. You want to give them pause, by letting them know they may incur liability; you want to motivate them to resovle this; and you want to establish a paper trial that you are doing your part. You may, though, if this moves forward, need to retain a lawyer, though.
