After a car accident in California, medical bills can pile up fast. Whether you were hit in downtown Los Angeles or sideswiped along I-80 near Sacramento, you might wonder who will end up paying those expenses. Who pays medical bills in a car accident in California depends on several factors, including fault, insurance coverage, and whether you pursue a legal claim. While your health is the priority, getting clarity on payment can help you plan next steps and avoid unexpected debt.
Who Pays Medical Bills in a Car Accident in California?
In most California car accidents, the injured person’s health insurance will cover the immediate medical care. That includes ambulance transport, emergency room visits, diagnostic imaging, and follow-up treatment. However, your health insurer may later seek reimbursement through a process called subrogation if someone else is found to be at fault for the crash.
California follows a fault-based system. Under California law, the driver who caused the accident is financially responsible for injuries. That means their auto liability insurance should cover your bills. However, those payments do not arrive immediately. You often need to pay upfront, then recover compensation through a claim or lawsuit.
Does Health Insurance Cover Car Accident Injuries?
Your health insurance plan typically covers car accident medical bills just like any other injury. However, if your insurer finds out another party is at fault, it may issue a lien or demand repayment from any settlement you receive. This is especially common with ERISA or Medicare-backed plans.
You also may have Medical Payments (MedPay) coverage as part of your own auto insurance policy. MedPay pays for accident-related care regardless of fault, up to the purchased limit. It can cover co-pays, deductibles, and costs that your health plan excludes. Not everyone carries this optional coverage, but it can help bridge the gap in coverage.

When Will the At-Fault Driver’s Insurance Pay?
If another driver caused your injuries, their insurance will likely pay your medical expenses, but only after liability is accepted or proven. That might take months or longer. In the meantime, you must either use your health insurance or pay out of pocket.
After you reach maximum medical improvement, your attorney may negotiate a settlement that includes all treatment costs, projected future care, and related damages. Once that agreement is reached, the at-fault driver’s insurer cuts a check that can be used to repay your providers and reimburse your health insurer.
Will Health Insurance Pay for Auto Accident Injuries If You Sue?
Filing a personal injury lawsuit does not affect your right to use health insurance. Most people rely on their health benefits while the case moves forward. Your provider may send a notice of lien to protect its reimbursement rights, but that does not stop your treatment.
California law recognizes these reimbursement rights in civil claims. If you reach a verdict or settlement, the health insurer is typically paid from those funds. A good attorney can help reduce that amount during settlement negotiations.
What If You Do Not Have Health Insurance?
If you are uninsured, hospitals may still treat you, but they may also pursue collection if the bills go unpaid. Some doctors will agree to treat you under a lien, which means they delay collecting payment until your claim is resolved. Others may require upfront cash.
Will You Be Left With Bills After a Settlement?
Sometimes. If your settlement is too low, or if liens exceed the recovered amount, you may owe remaining balances. That is why the total value of your treatment, including future care, must be part of your damage calculation. California law allows injured people to recover the reasonable value of medical services as part of a personal injury claim.
When handled properly, your attorney can structure your recovery to cover your medical costs, lost wages, and pain-related damages. The goal is to avoid leaving you with bills after your case is closed.
How to Protect Yourself After an Accident
If you are receiving treatment and are unsure how your bills will be paid, take these steps:
- Use your health insurance to stay current on care;
- Ask your attorney to explain MedPay or lien options;
- Save all billing statements and insurance correspondence; and
- Communicate with providers to avoid missed payments or collections.
Do not wait for the insurance company to act. California law limits the time you have to file a claim, and missing treatment windows can harm both your health and your legal case. Early legal guidance can help keep your recovery on track and clarify your options under state law.
