After a California car crash, most injured drivers focus on two things: the at-fault driver’s liability insurance and their own health plan. There is a third piece of coverage sitting quietly on many auto policies that can pay your medical bills quickly, without a fault fight, and without a deductible. It is called Medical Payments coverage, or MedPay, and it is one of the most useful and least understood features of a California auto policy.
We see MedPay misused, ignored, or signed away every week. Clients call us months after an accident wondering why a hospital is still chasing them when they had $5,000 in MedPay sitting on the policy the whole time. Or worse, they used MedPay correctly but then signed a broad reimbursement form that gave the insurer more rights than the policy itself required. This article explains, in plain language, what MedPay is, how it interacts with the rest of your case, and how to use it the right way.
What MedPay Actually Covers in California
MedPay is an optional first-party coverage on a California auto policy. It pays reasonable and necessary medical expenses for you, your passengers, and usually household family members after a crash, regardless of who was at fault, up to the dollar limit you purchased. California insurers are required to offer at least $1,000 in MedPay coverage, but drivers are not required to buy it. Common limits we see on policies are $1,000, $2,000, $5,000, $10,000, and $25,000 per person, with some carriers writing higher.
Covered expenses typically include:
- Ambulance and EMT transport
- Emergency room and hospital bills
- Surgery, imaging, and diagnostics
- Doctor visits, physical therapy, and chiropractic care
- Dental work or prosthetics related to the crash
- Nursing care
- In some policies, funeral expenses
There is no deductible and no copay. Unlike health insurance, MedPay does not care about networks, and unlike the at-fault driver’s bodily injury coverage, MedPay does not require you to prove anyone was negligent. If you were in the vehicle and you were hurt in a crash, the policy responds.
One important clarification: MedPay is sometimes loosely called “no-fault” coverage because you do not have to prove fault to collect. But California is a fault-based state. MedPay is not the same as the Personal Injury Protection (PIP) systems used in states like Florida or New York. It does not pay lost wages, household services, or general damages. It is strictly a medical expense bucket.
How MedPay Stacks With Health Insurance and the At-Fault Driver’s BI Coverage
The most common question we get is whether MedPay overlaps with health insurance or with the other driver’s liability coverage. The short answer is that MedPay is generally designed to be primary for accident-related medical bills, up to your limit.
Here is how the layers typically work in a California claim:
- MedPay pays first. Providers can often bill MedPay directly. Bills get paid quickly, which keeps collections off your back and lets your treatment continue without interruption.
- Health insurance picks up after MedPay is exhausted. Once your MedPay limit is used up, your health plan becomes the primary payer for ongoing care, subject to its deductibles, copays, and network rules.
- The at-fault driver’s bodily injury (BI) liability coverage pays later. When the third-party claim resolves through settlement or verdict, that recovery is supposed to compensate you for the full value of your medical expenses, lost wages, and pain and suffering.
This is why we describe MedPay as a bridge. It gets bills paid while the liability claim is still pending, which can take months or years. If you are facing a $3,000 ER bill and a $4,000 MRI two weeks after a crash, waiting for the at-fault carrier to evaluate your claim is not realistic. MedPay solves that timing problem.
There is a catch, however. When you later recover from the at-fault driver, both your MedPay insurer and your health plan may assert reimbursement rights against your settlement. That is where liens and subrogation come in.
MedPay Subrogation, Health Plan Liens, and Provider Liens
Most California auto policies that include MedPay also include a contractual reimbursement or subrogation clause. That clause gives the MedPay insurer the right to be repaid from any personal injury settlement or judgment you receive that covers the same medical expenses they paid.
You also need to be aware of other lienholders who may show up on your file:
- Private health insurers with contractual reimbursement language in the plan
- Medi-Cal, which has a statutory right of recovery under California Welfare and Institutions Code section 14124.70 et seq.
- Hospitals, which can assert statutory liens on third-party recoveries under California Civil Code section 3045.1 et seq.
- Providers treating on a lien basis, where the doctor agrees to wait for payment until the case resolves
- ERISA self-funded health plans, which often have powerful federal reimbursement rights
California courts will generally enforce a MedPay subrogation clause if the policy language is clear. But those rights are limited by two important equitable doctrines that often shape the final numbers in a settlement: the common fund rule and the made-whole doctrine.
The Common Fund and Made-Whole Doctrines
These two doctrines are where good lawyering can put real money back in your pocket.
The common fund doctrine holds that when an attorney creates a recovery (a “common fund”) that benefits another party, like a MedPay insurer waiting to be reimbursed, that party must contribute a proportionate share of the attorney’s fees and litigation costs. In practical terms, if your lawyer recovers $100,000 from the at-fault driver and the MedPay carrier wants its $5,000 back, the carrier typically must reduce its claim to account for its pro rata share of the contingency fee and costs. The MedPay insurer cannot ride free on the work that produced the recovery.
The made-whole doctrine goes further. It provides that an insurer’s reimbursement right may be limited or eliminated when the injured person has not been fully compensated for their total losses. If the at-fault driver carries only minimum policy limits and your damages far exceed those limits, you have not been made whole. In that scenario, California law often allows a strong argument that the MedPay carrier should accept a reduced reimbursement, or in some cases nothing at all.
ERISA self-funded plans are a different animal. Federal law typically allows those plans to enforce their written reimbursement terms, and many of them expressly disclaim the made-whole doctrine. That is why a careful review of plan documents matters before any settlement is finalized. We have seen six-figure ERISA liens turn into much smaller numbers with the right negotiation, but it takes a document-by-document analysis, not assumptions.
In our experience, many MedPay carriers will voluntarily compromise their reimbursement claims to account for common fund and made-whole exposure rather than fight over relatively small dollar amounts. But that compromise rarely happens unless someone asks for it and supports the request with the right legal framework.
Why John’s Medical Background Matters Here
John Reardon spent 20 years as a chiropractor before practicing law. That clinical experience shows up directly in MedPay cases in two ways.
First, we understand which bills are properly attributable to the crash and which are not. MedPay only pays for reasonable and necessary expenses related to the accident. Insurers sometimes deny or delay payment by arguing that imaging or therapy was not crash-related. Having a lawyer who has personally read thousands of MRI reports, ordered diagnostic studies, and documented soft-tissue injuries lets us push back with substance, not just legal arguments.
Second, we know how providers actually bill. Hospital billing, chiropractic billing, and physical therapy billing each follow different conventions, and the CPT codes that show up on a MedPay claim are not always the codes that should show up. When MedPay limits are tight, getting the billing right can mean the difference between MedPay covering an entire course of care versus running out partway through.
Practical Steps to Use MedPay the Right Way
If you have been in a California crash, here is how to make sure MedPay works for you and not against you.
Find out whether you have MedPay and what the per-person limit is. Pull up your declarations page or call your agent. If you do not see a line item for medical payments coverage, you likely do not have it. If you do, note the limit. That is the maximum the policy will pay per injured person.
Ask whether providers can bill MedPay directly. Some carriers prefer that you submit bills yourself; others accept direct provider billing. Direct billing is usually faster and keeps you out of the middle.
Do not sign broad reimbursement forms or medical authorizations without legal review. MedPay insurers sometimes send forms that go beyond the policy’s actual reimbursement language, or that grant sweeping access to your entire medical history. Have an attorney review anything you are asked to sign.
Keep your bills, EOBs, and payment records organized. When the case resolves, your lawyer needs to know exactly what MedPay paid, what your health plan paid, and what is still outstanding. Good records make lien negotiations faster and almost always produce better outcomes.
Use MedPay early, not as a last resort. MedPay is most valuable in the first weeks and months when bills are arriving and the liability claim is nowhere near resolution. Holding it back rarely makes sense.
Be aware of California’s fair claims handling standards. California Insurance Code section 790.03 and the regulations under it require carriers to handle claims promptly and in good faith. If your MedPay carrier is dragging its feet or demanding fault documentation it does not actually need under the policy, those rules give your attorney leverage to push for faster payment.
We Can Help You Sort This Out
MedPay seems simple on the surface, but the interplay between MedPay, health insurance, hospital liens, ERISA plans, and the at-fault driver’s BI coverage is where injury cases quietly gain or lose tens of thousands of dollars. We have spent years navigating those interactions for California clients, and we have seen how a thoughtful approach to coverage and liens changes what an injured person actually takes home at the end of the case.
