Which Insurance Pays After an Auto Accident? Uninsured Motorist, PIP and MedPay
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, but personal injury protection (PIP), MedPay and uninsured motorist (UM) coverage can matter just as much. An auto accident lawyer usually requests the declarations page for every policy that might apply, because the coverage often decides how much of a loss can be paid.
How fault rules shape coverage
Most states require drivers to carry minimum 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, in which each driver's own PIP coverage pays medical expenses and some lost income regardless of fault. No-fault states may restrict lawsuits against the at-fault driver unless the injury meets a legal threshold.
PIP and MedPay coverage
No-fault states require PIP, and a few other states do as well, 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, usually called MedPay, is separate and generally smaller. It pays medical expenses for the policyholder and passengers regardless of fault, up to its policy limit. A car crash lawyer will check whether these benefits require prompt notice or a written claim.
Uninsured and underinsured motorist coverage
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 fall short of the loss. Some states require UM coverage, while others allow it to be rejected in writing. Rules for stacking coverage from several vehicles or policies also vary by state. In some states, a policy held by a relative in the same household may provide UM coverage as well.
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. Policies often require prompt notice of the claim, and hit-and-run claims may depend on 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.
Repairs and rentals
Collision coverage pays to repair or replace the policyholder's car regardless of fault, minus the deductible. The insurer may then seek repayment from the at-fault driver's insurer through subrogation, and the deductible is sometimes recovered too. Gap insurance and rental reimbursement are optional coverages that can matter after a total loss.
Health plans and repayment
Medicare, Medicaid or a health plan may pay medical bills first and later seek repayment from a settlement. An automobile accident lawyer will usually resolve those liens before any money is distributed. Coverage rules vary by state and by policy, and this is general information rather than legal advice.
