This is a complicated question, made more complicated by the ever-changing healthcare system. Ultimately, the other driver, or their insurance carrier, may be responsible for reasonable medical expenses incurred as a result of the accident. Legally, you must prove to a reasonable degree of medical probability that your medical expenses were necessitated by the accident. You also have to prove that your medical expenses were reasonable. Oftentimes, it is best to have your health insurance carrier pay your medical bills at the outset, as the other driver or their insurance carrier will not issue payment until your entire case settles. You may have “med-pay coverage” on your auto insurance policy. This coverage will cover medical expenses related to the accident. If you have health insurance, you should use your med-pay coverage to assist you in paying co-pays and/or deductibles. Given the complexity of this issue, it is important to contact an attorney as soon as possible after an accident so they may address the specific facts of your case.
