Who Pays Medical Bills After a Car Accident?

Published 2026-10-21

Health insurance, MedPay, PIP and the at-fault driver's insurer may all play a role. Here is how medical bills are usually handled after a crash.

Medical bills can arrive before you know whether the other driver's insurer will pay. Who covers what depends on your state, your own policies and who was at fault. This overview explains the usual sources of payment.

Your health insurance

Many people use their health insurance first so treatment is not delayed. Your health insurer may later seek reimbursement from any settlement you receive. This is often called a lien or subrogation claim.

Medical payments coverage (MedPay)

Some auto policies include MedPay, which can cover medical expenses for you and your passengers regardless of fault, up to the policy limit.

Personal injury protection (PIP) and no-fault states

In no-fault states, your own auto policy's PIP coverage pays certain medical costs and sometimes lost wages after a crash, no matter who caused it. Rules about when you can also claim against the other driver vary by state.

The at-fault driver's insurance

If another driver caused the crash, their liability insurance may eventually compensate you for medical bills and other losses, usually through a settlement. This can take months, and the insurer decides what it will accept as reasonable and related to the crash.

Uninsured and underinsured drivers

If the at-fault driver has no insurance or too little, your own uninsured/underinsured motorist coverage, if you have it, may help.
