How Uninsured Motorist Coverage, PIP and MedPay Work After a Car Accident
By @remingtonvcgi992
More than one insurance policy can apply after a car crash. People usually think first of the at-fault driver's liability coverage, yet personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter as much. An auto accident lawyer will usually ask for the declarations page of every policy that might apply, since coverage often decides how much of a loss can be paid.
At-fault and no-fault states
Most states require drivers to carry minimum liability insurance, which pays for injuries and property damage the insured driver causes to others. Minimum limits are often low compared with the cost of a serious injury. In an at-fault state, the injured person usually makes a claim against the at-fault driver's insurer. A smaller group of states uses a no-fault system, where each driver's own PIP coverage pays medical expenses and some lost income regardless of who caused the crash. No-fault states may restrict lawsuits against the at-fault driver unless the injury meets a legal threshold.
PIP and MedPay
No-fault states require PIP, and a few other states do as well, and some others offer it as an option. Depending on the policy, it can pay medical bills, part of lost wages and certain household expenses. Medical payments coverage, usually called MedPay, is separate and generally smaller. The coverage pays medical expenses for the policyholder and passengers no matter who caused the crash, up to its policy limit. An auto accident attorney will check whether these benefits require prompt notice or a claim form.
When the other driver has little or no insurance
Uninsured motorist (UM) coverage pays for injuries caused by a driver who has no insurance, and many states extend it to hit-and-run crashes. Underinsured motorist (UIM) coverage applies when the at-fault driver's limits are too low to cover the loss. Some states require UM coverage, and others let a policyholder reject it in writing. Rules on stacking coverage from more than one vehicle or policy also vary. A relative's policy in the same household may also provide UM coverage in some states.
Making a UM claim
The UM claim goes to the injured person's own insurance company, but in that claim the insurer takes the position of the uninsured driver, which means it can contest fault and the value of the claim. Policies often require prompt notice of the claim, and a hit-and-run claim may require a timely police report. In some states, the UM insurer must be served with a copy of any lawsuit against the at-fault driver. An auto accident lawyer will check these requirements early, because missing one can affect the coverage.
Vehicle damage coverage
Collision coverage pays for repairs to the policyholder's car regardless of fault, less the deductible. The insurer can then seek repayment from the at-fault driver's insurer through subrogation, which can sometimes recover the deductible as well. Rental reimbursement and gap insurance are optional coverages that can matter after a total loss.
Health insurance and liens
Health insurance, Medicare or Medicaid may pay medical bills first and later claim repayment from a settlement. A motor vehicle accident attorney usually resolves these liens before funds are distributed. Coverage rules vary by state and by policy, and this is general information rather than legal advice.
