Personal injury protection (PIP) is an extension of car insurance available in some U.S. states that covers medical expenses and, in some cases, lost wages and other damages. PIP is sometimes referred to as "no-fault" coverage, because the statutes enacting it are generally known as no-fault laws, and PIP is designed to be paid without regard to "fault," or more properly, legal liability. That is, even if the person seeking PIP coverage caused the accident, they are entitled to make a claim under the PIP portion of their policy. "No-Fault" does not mean that insurance premium of the person making the claim will not increase. Typically a PIP claim is made by the insured driver to their own insurance company, however, there are several exceptions that allow persons who have been injured in an accident to make a PIP claim if they do not own a vehicle. The particular state law and policy language of the insurer should be reviewed to see what exceptions exist in that state. Auto insurance PIP is a mandatory coverage in some states. PIP coverage may vary from state to state in terms of both what is covered and what types of treatments are considered medically necessary and reasonable. In Texas, PIP coverage will cover medical expenses, eighty percent of lost wages, and someone to take care of the injured party. Some states also allow for PIP claims even if a workers' compensation claim exists, while others do not. Some states PIP is the insurance of first resort to pay for medical bills when injured in an automobile accident. In some states, PIP is subrogatable, meaning that your insurance carrier will pay for your loss, regardless of liability, and then recover (or subrogate) what it paid from the liable party's insurance carrier. This generally leaves the claimant/insured in a much better financial position, because his or her medical bills are paid, and the insurance carriers get to fight it out on their own, and after the fact. PIP can cover, within the specified dollar and time limits, the medical and funeral expenses of the insured, others in its vehicle at the time of the loss, and any first party if struck as a pedestrian by any vehicle. The basic coverage is for the insured's own injuries, on a first-party basis, without regard to liability. Again, it is only available in certain states. A pedestrian struck
