If you have been injured in a car accident that was someone else’s fault, that party should be held responsible for compensating you for the medical expenses you incur in the care and treatment of your injuries. Of course, a car accident claim can take time to resolve, as bills for your medical expenses pile up. While you are waiting to resolve your legal claim, you may be able to cover your medical costs through Med Pay coverage under your car insurance policy (assuming you did not opt-out of this coverage) or through your personal health insurance policy (unless your health insurer expressly excludes coverage for treatments related to a motor vehicle accident).
