This is question has a lot of issues. First, is the issue of coverage. In Georgia, there is what is called medical payments coverage through your automobile insurance carrier. The coverage is based upon what limits you selected prior to the auto collision. If that is the coverage you are referring too, you should find out why they are not paying for your medical care.
Under Georgia law they do not have to pay for all medical care, just medical care that is reasonable and necessary as it relates to your car wreck claim. Therefore, if the care is not related to the car wreck that may be a reason.
Unfortunately now a days they sometimes refuse to pay arguing that the medical care is not reasonable and necessary so that they can save cost. Look closely because the medical provider may have improperly coded the charge. If this is the case, it is possible that the medical provider can correctly code the charge and the insurance company will pay the charge.
If the reason they are not paying is they have paid out all available insurance coverage, there is not much that can be done. If for example you only have $2,000.00 in medical payments coverage and the insurance company paid $2,000.00 out, they will not continue to pay any bills under any circumstances.
