How Uninsured Motorist Coverage, PIP and MedPay Work After a Car Crash
By @titushbpj477
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. A car accident lawyer will usually ask for the declarations page of every policy that might apply, because the coverage often decides how much of a loss can be paid.
Liability coverage and fault
Most states require drivers to carry a minimum amount of liability insurance, which covers injuries and property damage the insured driver causes to others. Minimum limits are often low compared with the cost of a serious injury. In at-fault states, the injured person generally claims against the at-fault driver's insurer. Some states use 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
PIP is required in no-fault states and in a few other states, while some states offer it as an option. Depending on the policy, it may cover medical bills, a share of lost wages and some household expenses. Medical payments coverage, often called MedPay, is a separate and usually smaller coverage. The coverage pays medical expenses for the policyholder and passengers no matter who caused the crash, up to the limit on the policy. An auto accident attorney will check whether these benefits require prompt notice or a written claim.
Uninsured and underinsured motorist coverage
Uninsured motorist (UM) coverage applies when the at-fault driver 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.
How a UM claim works
The UM claim goes to the injured person's own insurance company, yet in that claim the insurer stands in the shoes of the uninsured driver, which means it can contest fault and the value of the claim. Many policies require prompt notice, and hit-and-run claims may depend on a timely police report. Some states require that the UM insurer be served with a copy of the lawsuit against the at-fault driver. An auto accident lawyer usually checks these steps early, because missing one can affect the coverage.
Coverage for the car itself
Collision coverage pays to repair or replace the policyholder's car regardless of fault, minus 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. Gap insurance and rental reimbursement are optional coverages that can matter after a total loss.
Health plans and repayment
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 article is general information, not legal advice.
