Who pays medical bills after a car accident in California?

Bills often arrive before answers

After a crash, medical bills can start arriving within weeks, while questions about fault and insurance take longer. California does not use a no-fault auto insurance system, so the at-fault driver’s liability insurance usually does not pay medical bills as they arrive. Payment from that insurer, if any, typically comes later as part of a settlement or judgment.

Coverage people often use first

Health insurance, including Medi-Cal and Medicare, often pays for treatment first, subject to normal copays and deductibles. Medical payments coverage (MedPay) on your own auto policy, if you have it, can pay medical expenses up to a set limit regardless of fault. Some people also have disability or supplemental policies through work.

Using these coverages does not end other claims, but the plans that paid may seek reimbursement from a later recovery. Health plans and government programs often have reimbursement rights, sometimes called liens or subrogation.

Hospital and provider liens

California’s Hospital Lien Act, beginning at Civil Code section 3045.1, allows hospitals that provide emergency and ongoing care to claim a lien on certain recoveries from a person responsible for the injury, subject to limits. Some providers also treat patients on a lien basis, meaning payment is deferred until a case resolves. Ask any provider to explain in writing how billing will work.

Practical steps

Keep every bill, explanation of benefits and receipt, and a log of appointments and mileage. Give providers your health insurance information unless you have a clear reason not to. If a bill goes to collections while a claim is pending, contact the provider and your insurer promptly. Do not delay needed care because of cost questions; ask providers about payment options.

Questions to ask

Questions often include whether your auto policy includes MedPay, whether your health plan expects reimbursement, and how provider liens work. A licensed attorney can explain how these rules apply to your situation. Next Step Injury is a free consumer advertising platform, not a law firm or a lawyer referral service. It does not evaluate situations or give legal advice. After an inquiry, a participating attorney may contact you, and you decide whether to work with that attorney.
