Med Pay vs. Health Insurance After a California Car Crash

After a crash in Los Angeles, Orange County or anywhere in Southern California, the medical bills often start arriving before anyone has decided who was at fault. That is when people ask a practical question: which insurance should pay for my treatment right now?

The short answer: Med Pay is optional coverage on your own auto policy that pays medical bills up to a set limit no matter who caused the crash. Health insurance is usually the main way to pay for ongoing treatment. In California you can often use both, but either one may ask to be paid back from any later settlement, so it helps to understand the rules before you sign anything.

This guide is written by Frank Stucki, Esq., MBA, a California-licensed plaintiff's trial lawyer, to help you make sense of the bills while you focus on getting better.

What Med Pay Is in California

Medical payments coverage, usually called "Med Pay," is an add-on to your own car insurance policy. California's minimum-insurance law requires liability coverage, which pays for harm you cause to others. It does not require Med Pay. Whether you have it depends on what you chose when you bought or renewed your policy, so check your declarations page.

Med Pay pays regardless of fault

The main benefit of Med Pay is that it does not wait for a fault decision. If you were hurt in a covered crash, Med Pay can pay reasonable medical expenses up to your policy limit whether you, the other driver or no one in particular caused it. Depending on the policy, it may also cover passengers in your car, and it may cover you as a pedestrian or bicyclist hit by a car.

What to know about Med Pay limits and rules

• Limits are usually modest. Med Pay is meant to cover early bills, deductibles and copays, not a full course of treatment for a serious injury.
• Time windows apply. Many policies only pay for treatment received within a set period after the crash.
• The policy controls. Who is covered, what counts as a medical expense and whether the insurer can ask to be repaid are all set by your policy language.
• Ask questions in writing. If you are unsure what your Med Pay covers or how a claim may affect your policy, ask your insurer or agent and keep the answer.

When to Use Health Insurance After a California Crash

Health insurance is usually the backbone for paying medical care after a crash. It covers ongoing treatment like physical therapy, imaging and specialist visits, and your plan's negotiated rates often make each bill smaller than the provider's full charge.

Some practical points:

• Give your health insurance card at every visit. Some providers will ask to bill the at-fault driver's insurer or to treat "on a lien" instead. Ask them to bill your plan, and get any other arrangement in writing.
• Stay in network when you can. Out-of-network bills can be harder to pay and harder to reduce later.
• Expect your plan to ask about the accident. Health plans often send a questionnaire asking whether another party caused your injury. Answer it honestly. Ignoring it can lead to claim denials.

How Med Pay and health insurance work together

For many people the simplest approach is:

1. Use health insurance as the main payer for treatment.
2. Use Med Pay to cover what health insurance does not, such as deductibles, copays, ambulance charges and other out-of-pocket costs.
3. Keep copies of every bill, explanation of benefits (EOB) and receipt.

If you have no health insurance, Med Pay may be the first and only coverage paying your early bills, and the claim against the at-fault driver becomes even more important. Every situation is different, so read your policy or ask a lawyer before deciding how to route the bills.

Getting Paid Back: Reimbursement, Liens and Subrogation in California

When you recover money from the at-fault driver, the companies that paid your bills may want some of it back. This is called reimbursement or subrogation. It is normal, and it can often be negotiated.

Med Pay reimbursement

Some Med Pay policies include a reimbursement clause, meaning the insurer can ask to be repaid from your recovery against the at-fault driver. Others do not. Read your policy, and do not assume the first amount an insurer asks for is final.

Health plan liens (Civil Code 3040)

California limits how much many health plans and health insurers can take back through a lien. Under Civil Code section 3040, a covered lien is generally limited to what the plan actually paid, and it is capped at one-third of your recovery if you have a lawyer, or one-half if you do not. The lien is also subject to a pro rata reduction for attorney fees and costs, and a reduction for your share of fault if a judge, jury or arbitrator makes that finding. The section does not apply to workers' compensation, Medi-Cal or hospital liens, and other plans and government programs can follow different rules.

California's hospital lien law (Civil Code 3045.1 and following)

California hospitals that treat someone injured by another person's wrongful act can claim a lien on the injured person's recovery for the reasonable and necessary charges of that care. A few general limits apply:

• Notice matters. The hospital must give written notice under the statute before an insurer or other payer can be held responsible for paying it.
• There is a cap. A hospital lien that has been properly noticed can generally reach no more than 50 percent of what is due under a judgment, settlement or compromise, after any prior liens are paid.
• Charges must be reasonable and necessary. The lien is tied to the reasonable and necessary charges for the treatment, not just any number on a bill.

Hospital liens can be confusing, especially when a hospital chose not to bill your health insurance. Do not ignore a lien notice, and do not pay one without understanding it.

California's Minimum Liability Limits Went Up in 2025

How much the at-fault driver's insurance can pay matters for every decision above. Under Vehicle Code section 16056, which Insurance Code section 11580.1(b) incorporates, policies issued or renewed on or after January 1, 2025 must carry at least:

• $30,000 for injury or death of one person
• $60,000 for injury or death of two or more people in one crash
• $15,000 for property damage

These increases came from SB 1107 (2022). The law also schedules another increase for policies issued or renewed on or after January 1, 2035. Many drivers still carry only the minimum, so your own Med Pay, health insurance and uninsured/underinsured motorist coverage can make a real difference.

The 2-Year Deadline in California

California's general deadline to file a lawsuit for personal injury is two years, under Code of Civil Procedure section 335.1. Some deadlines are much shorter. If a city, county or state agency is involved, such as a government vehicle or a dangerous public road, a written government claim is generally due within six months under Government Code section 911.2. Insurance policies also have their own notice requirements, so report the crash to your insurer promptly.

Practical Checklist

• Find your auto policy declarations page and check for Med Pay and uninsured/underinsured motorist coverage.
• Use your health insurance card at every visit.
• Save every bill, EOB, receipt and lien notice in one folder.
• Answer your health plan's accident questionnaire honestly.
• Do not sign a release or settle anything until you know who will want to be paid back.
