Who pays my medical bills after a car accident in California?
By Jimin Oh, Founding Attorney, Solution Now Law Firm. Last updated: November 2026.
In California, the at-fault driver’s insurance company does not pay your medical bills as you receive treatment. It pays once, at the end of the claim, as part of your settlement. Until then, your bills are usually covered by one of four sources: your own auto policy’s Med Pay coverage, your health insurance, a provider who treats you on a lien, or a government program such as Medi-Cal or Medicare.
Which option is best depends on your coverage and your case. Choosing the right one early can affect how quickly you get care and how much of your settlement you keep.
Why doesn’t the other driver’s insurance pay right away?
California is an at-fault state. The at-fault driver’s insurer is responsible for your injuries, but it typically will not pay anything until your treatment is complete and the claim is resolved. The insurer needs to see your full medical records and bills before it agrees to an amount, and it pays everything in a single settlement. This is why many accident victims receive bills, and sometimes collection notices, long before their case settles.
Option 1: Med Pay from your own auto policy
Medical Payments coverage, called Med Pay, is optional coverage on your own auto policy. It pays medical bills for you and your passengers regardless of who caused the accident, usually up to a set limit such as $1,000, $5,000, or $10,000. Using Med Pay does not mean you were at fault. Check your declarations page or ask us to review your policy. Keep in mind that if you later receive a settlement from the other driver’s insurance, your own insurer may ask to be reimbursed for what it paid under Med Pay. Your attorney can negotiate that reimbursement to maximize your share of the settlement.
Option 2: Your health insurance
You can use your health insurance after a car accident, and for emergency care you often will. The ambulance and emergency room will typically bill your health plan. However, many health plans have a right to be reimbursed from your settlement for what they paid. This is called subrogation or reimbursement, and it can take a meaningful portion of your recovery if it is not handled carefully. You will also still owe your usual copays and deductibles. And health insurance often comes with long waits for referrals, specialist appointments, and approvals for imaging like MRIs, which can delay your care and your recovery.
Option 3: Treatment on a lien
Many providers treat accident victims on a lien, including chiropractors, physical therapists, pain management doctors, imaging centers, orthopedic doctors, neurologists, and sometimes even surgeons. You receive treatment without paying anything up front and without using your health insurance. The provider sends bills and records directly to your attorney, and the provider is paid from the settlement when your case resolves.
Because these providers treat many accident victims, accident injuries are often their specialty. They also tend to keep thorough, detailed records, because they understand what insurance companies look at when evaluating a claim. Detailed records that fully document your injuries, your symptoms, and how they affect your daily life can make a real difference in the value of your settlement.
This is often the fastest way to start treatment, and it gives your attorney a chance to negotiate those bills at the end of the case, which can leave more of the settlement in your pocket. The important detail is that lien-based providers generally work only with patients who are represented by a law firm they know and trust. Without an attorney, most will ask you to pay out of pocket.
This is another reason a local law firm matters. A local firm knows which providers in your area are best for which kinds of injuries, and works with them collaboratively to help you recover and to support your claim.
Option 4: Medi-Cal or Medicare
If you have Medi-Cal or Medicare, it can pay for accident-related care. Both programs are entitled to be repaid from your settlement, and both have formal processes for calculating the amount owed. These claims must be resolved before settlement funds are fully released, so it is important to tell your attorney early if you have either program.
Which option is best for my case?
Every case is different. Sometimes using health insurance is the best choice. Sometimes treating on a lien is better. The right approach depends on several factors, including:
- Your prior injuries or medical history, especially if you had treatment for the same area of your body before the accident
- The insurance policy limits available, both the other driver’s and your own
- The severity of the accident
- The injuries you suffered and the treatment they are likely to require
It is important to work with a law firm that understands how all of these factors fit together and can build the right treatment and payment plan for your case from the start.
What about hospital bills?
If you were taken to a hospital, the hospital may bill your health insurance or may place a lien on your settlement under California’s Hospital Lien Act. Hospital bills are often the largest bills in a case. An attorney can request itemized bills, confirm the charges are accurate, and negotiate reductions before your settlement is paid out.
Do I have to pay anything up front?
You are responsible for any copays or deductibles if you use your health insurance. If you treat on a lien through your attorney, you generally pay nothing up front. Either way, do not ignore bills or collection letters. Forward them to your attorney, who can notify providers that your claim is pending and ask them to hold collections while the case is open.
What if the accident happened at work?
If you were driving for work when the accident happened, workers’ compensation may pay your medical bills and part of your lost wages. You may also have a separate claim against the at-fault driver. These cases involve different rules, so speak with an attorney before choosing how to proceed.
The most important step: do not delay treatment
Confusion about who pays is one of the most common reasons accident victims put off seeing a doctor. Delays can make recovery harder, and insurance companies often point to gaps in treatment as a reason to offer less. If you are hurt, get evaluated promptly, and sort out payment with your attorney’s help.
