Quick answer
In the short term, your own coverage usually pays: health insurance, med pay on your auto policy, Medi-Cal or Medicare. The at-fault driver's insurer typically pays once, at settlement or judgment, and whoever paid your bills may have a right to be repaid from that money. Under Howell v. Hamilton Meats (2011), recovery for past care paid by insurance is limited to the amounts actually paid or still owed.
Who pays your medical bills after a car accident in California? In the short term, usually your own coverage: health insurance, medical payments coverage on your auto policy, Medi-Cal or Medicare. The at-fault driver’s insurer does not pay bills as they come in. It pays once, at settlement or judgment, and whoever paid your bills along the way may have a right to be repaid from that money.
We are B&D Law Group, APLC, a California personal injury firm. This guide explains who pays first, how liens work, and why the amount you can recover for past medical care depends on what was actually paid.
Who Pays While Your Claim Is Open
Health insurance generally pays under its normal terms, subject to your copays and deductibles. Medical payments coverage, known as med pay, is optional coverage on many auto policies that pays medical costs up to a set limit regardless of fault. Medi-Cal and Medicare pay for covered care as well. Some providers agree to treat on a lien, meaning they wait to be paid from the settlement.

Liens: Paying Back What Was Paid
Several payers can have a right to reimbursement from your recovery. Under Civil Code section 3045.1, a hospital that treated you can have a lien on damages you recover from the person who caused the injury, for its reasonable and necessary charges. Under Civil Code section 3045.4, the hospital can collect its lien only up to 50 percent of your recovery after prior liens are paid.
If Medi-Cal paid for your care, the Department of Health Care Services has a right to be repaid from a settlement or judgment under Welfare and Institutions Code sections 14124.70 through 14124.795. According to DHCS, you or your representative must notify it in writing within 30 days of filing a personal injury action or claim. Medicare can also make conditional payments that must be repaid from a settlement. Private health plans may have repayment rights depending on the plan.
How Much You Can Recover for Past Medical Bills
In Howell v. Hamilton Meats & Provisions (2011), the California Supreme Court held that an injured person whose medical care was paid by insurance may recover only the amounts actually paid or still owing, not the full billed amount a provider wrote off. That rule shapes how past medical damages are calculated in many cases.
Keep Records From Day One
Keep every bill, explanation of benefits and receipt, and follow your doctors’ treatment plans. Gaps in treatment are often used to argue an injury was minor. Our guide on delayed symptoms after a car accident explains why getting seen early matters even if you feel fine.
Deadlines Still Apply
Code of Civil Procedure section 335.1 generally gives you two years from the date of injury to file a personal injury lawsuit, and a claim against a public entity requires a written government claim within six months under Government Code section 911.2.
