PIP coverage

Personal injury protection, a no-fault auto coverage that generally pays medical costs after a crash up to a set limit.

Collision Bureau is not a law firm and this is not legal or medical advice. It is general information about what happens after a crash. For advice on your situation, talk to an attorney licensed in your state or a treating clinician.

What it means

Personal injury protection, usually written as PIP, is a kind of auto coverage that pays medical costs after a crash regardless of who caused it. The no-fault label refers to that structure: your own policy pays first, up to the limit you bought, without waiting for a determination of fault. In broader versions, PIP also pays a share of lost income and some essential services during recovery. The question of whether PIP exists for you depends on your state and your policy, and the declarations page is the single document that answers it.

How it works

The coverage works like a prepaid pool for crash-related medical costs. A limit sits on your policy, usually several thousand dollars at the low end and much higher in states where PIP functions as a primary system. Bills from treatment after a crash get submitted to the PIP carrier, which pays within policy terms until the limit is reached. The order in which PIP pays relative to MedPay and your health plan depends on your state and your policy language, and the differences are not minor. In some no-fault states, PIP is designed to be the first and often only source for medical bills within the limit, which is why the policy limit is a decision worth understanding before a crash rather than after.

Why it comes up

It comes up in the first days after a crash, when bills start arriving and the question of who pays as you go has to be answered. The Insurance Information Institute keeps background on no-fault systems that shows how differently states build this machinery. PIP also comes up at claim resolution, because the carrier that paid medical bills under PIP generally has a subrogation interest in any recovery from the at-fault side, which has to be reconciled when the file closes.

What it is not

PIP is not liability coverage, and it is not a payout from the at-fault driver's insurer. It is the coverage on your own policy, operating on your side of the claim. It is also not the same as MedPay, though the two can look similar on a declarations page. MedPay is narrower in scope in most states. PIP is broader, bigger, and set up to carry more of the early load, and in states where PIP is required the coverage is structural rather than optional. The right starting point is your declarations page, and the right follow-up question is for a licensed attorney in your state.

Questions people actually ask

01Do I have PIP coverage automatically?

Only if your state requires it or you added it to your policy. Some states require PIP on every auto policy, some offer it as an option, and some do not have it at all. Your declarations page states what you carry and the limit that goes with it. If the line is on the page, the coverage exists for your claim. If it is not, the coverage is not part of your file, and the medical bills route to the sources that are.

02Does PIP replace health insurance after a crash?

No. PIP is a separate auto coverage. Which pays first, and how the two interact when both apply, depends on your state and your policy language. In some states PIP is primary and the health plan is secondary. In others the order is reversed. A general information page cannot resolve the order for you. Your declarations page shows what you have, and a licensed attorney in your state tells you how it stacks.

03Does PIP cover anything besides medical bills?

In some states and some policies, yes. Broader versions of PIP can pay a share of lost income, essential services like household help during recovery, and in some states funeral expenses. The specifics are set by state law and by the policy itself. Which items are inside your coverage, and up to what cap, is written on your declarations page. Any question about how the pieces apply to a live claim is attorney territory.
