Medical bills can become one of the most confusing parts of an injury claim. An injured person may have health insurance, Medicare, Medi-Cal, medical payments coverage, or a doctor who agrees to wait for payment through a lien. Each arrangement creates different rights and obligations.
A common mistake is assuming the other driver's insurance company will simply pay the bills as they arrive. That usually is not how a claim works. A second point is easy to miss: even when someone else caused the accident, the bills may still be the injured person's responsibility to the provider. The question of who caused the accident and the question of who owes the doctor are separate.
Key Takeaways
- The other driver's insurer generally does not pay your medical bills as they come due, even when its insured caused the accident.
- Health insurance may pay, but the plan may later seek reimbursement from your recovery.
- Medicare and Medi-Cal have their own recovery procedures and are not ordinary medical liens.
- Treatment on a lien is deferred payment, not free care. The written agreement matters.
- A large bill is not automatically a large claim. Under the Howell rule, amounts written off by a provider may not be recoverable.
- Civil Code § 3040 limits only certain liens, not every medical lien.
- Med-Pay under your own auto policy can help while a claim is pending.
- The number that matters is net recovery, not the gross settlement.
Bills and statements are worth keeping organized from the start.
Why the Other Driver's Insurer Doesn't Pay the Bills
This is one of the first things that surprises people. Someone else caused the collision, so it seems logical that their insurer should pay the resulting bills. But a liability claim does not normally work that way. The injured person receives care, the provider sends the bill to the appropriate source of payment, and the other insurer investigates the injury claim separately.
That insurer may also disagree with the treatment. An adjuster may question whether care was necessary, lasted too long, had gaps, was reasonably priced, was related to the accident, or was influenced by a preexisting condition. A bill having been sent does not resolve those questions. Bills should never simply go into a drawer on the assumption that someone else will take care of them.
For the adjuster's perspective, see Dealing With Insurance Companies.
The Medical Bills Are Still Your Problem
Imagine vandals damage your house and you hire a handyman to repair it. You cannot normally tell the handyman to go find the vandals for payment. You have the relationship with the handyman and are generally responsible for paying under your agreement. You may then have a claim against the vandals.
Medical bills work on a similar principle. The person who caused the accident may ultimately be responsible for your damages, but that does not automatically eliminate your obligations to your providers.
If medical bills arrive in the mail, do not throw them away and say it is the other driver's problem. It isn't that simple.
What Is a Medical Lien?
"Medical lien" is a term people use for several different arrangements, and they are not all legally the same.
Provider lien
A provider treats now and agrees to be paid from the eventual settlement or judgment, under a written lien agreement.
Health plan reimbursement
A health insurer pays the provider and later asserts a reimbursement or subrogation claim.
Medicare
Medicare makes a conditional payment and later seeks reimbursement when the case produces a recovery.
Medi-Cal
A statutory recovery system administered by the California Department of Health Care Services.
Hospital lien
A hospital may have statutory lien rights under California's Hospital Lien Act.
ERISA plans
Certain employer-sponsored health plans are governed by federal ERISA rules.
Before deciding how much anyone should be paid, the first question is: who paid for the medical care, and what legal right does that person or entity have to seek reimbursement? The Glossary defines terms like subrogation, conditional payment and ERISA.
Treatment on a Lien Is Not Free
Sometimes an injured person lacks health insurance, has inadequate coverage, or cannot get timely treatment through the ordinary system. A provider may agree to treat on a lien basis. That can be useful, but it helps to understand what is happening: the provider is not giving away the care. The provider is agreeing to postpone collection.
If the case is later lost, then depending on the agreement and applicable law, the patient may still owe the provider for the treatment. That is why the agreement should be understood before it is signed.
Before signingQuestions worth asking about a lien agreement
- How much is charged for each service?
- What happens if the case does not settle?
- What happens if the case is lost?
- Is interest charged?
- Can the balance be negotiated?
- What if the settlement is too small to pay the lien?
- Is the provider obligated to reduce the bill?
Treatment on a lien can sometimes be the right choice. It just should not be confused with free medical care.
Your Own Doctor May Be the Better Choice, or Not
There is no universal rule that treating on a lien is better or worse than using health insurance. Consider someone with a significant back problem before the accident who claims the accident aggravated it. A physician who treated the patient beforehand has prior records, examinations and perhaps imaging, a basis for comparing the condition before and after. That can be powerful evidence.
The problem is access. An established physician's next opening may be four or five months away, and the defense may later ask why the person waited so long to get treatment. The answer may be perfectly legitimate, but the delay can still be questioned.
Sometimes obtaining appropriate treatment sooner through another provider makes more sense. The better approach is to weigh the patient's actual needs, the availability of providers, and the financial consequences of the arrangement, rather than automatically choosing one payment method.
Treatment timing also matters as evidence; see Getting Medical Care.
A Large Bill Is Not Always a Large Recoverable Bill
Someone with a modest used car can put an enormous price tag on it, but the asking price does not make it worth that. Medical bills call for the same kind of analysis. A provider's billed charge does not automatically establish the amount recoverable as past medical expenses. This is especially true when health insurance has a contractual rate with the provider: if a hospital bills a very large amount but has agreed with the insurer to accept far less as payment in full, the original charge does not necessarily represent the patient's economic loss.
The California Howell rule
California's Supreme Court addressed this in Howell v. Hamilton Meats & Provisions, Inc., 52 Cal.4th 541 (2011). In general terms, when a provider has agreed with a private health insurer to accept a lower amount as payment in full, the injured plaintiff cannot recover the amount that was written off and never became the plaintiff's obligation.
There is an important qualification. Howell does not establish that the amount paid by an insurer is automatically the "reasonable value" of care in every situation. California cases have treated insured and uninsured patients differently, and the circumstances of the patient's obligation matter. Billing requires analysis, not just adding up the numbers on the bills.
Expect Questions About the Bills
Adjusters and defense attorneys examine much more than the total. They may use medical-billing databases or software, and may retain medical experts or billing specialists. That should not be taken personally. Questioning treatment is part of evaluating a claim, not necessarily an accusation of dishonesty.
- How quickly treatment began
- Gaps in treatment
- Whether the pattern was medically expected
- Consistency of complaints across records
- Prior injuries or conditions
- Objective findings and imaging
- Whether care was reasonable and necessary
- Whether charges are reasonable for the area
- What was actually paid, and any discounts accepted
- Whether care was on a lien, and whether the provider has a financial interest in the outcome
Who May Claim Reimbursement From Your Recovery
Health insurance
People often ask why their health insurer should pay when the other driver caused the accident. Practically, health insurance may be exactly what pays for care when it is needed. But depending on the plan and applicable law, the plan may have a right to reimbursement if the injured person later recovers money. That is why a person can receive a settlement and then discover another entity expects to be paid from it.
California statuteCivil Code § 3040
Civil Code § 3040 can limit certain liens asserted by health care service plans, disability insurers, medical groups, and independent practice associations. For qualifying liens the statute contains limits tied to factors including amounts paid, the type of services, the recovery, attorney involvement, and attorney fees and costs. The limit is expressed as a share of the recovery, and the share differs depending on whether the injured person has an attorney.
There is no universal California rule that every medical lien can take only a fixed fraction of a settlement. Section 3040 does not apply to every type of lien. It specifically excludes certain claims, including Medi-Cal liens and hospital liens, and federal law can affect certain employee benefit plans. The type of claim must be identified before the statute is applied.
FederalMedicare is different
Medicare operates under federal law with its own recovery procedures. When it makes a conditional payment for accident-related care because another payer has not paid promptly, it may later seek reimbursement from a settlement, judgment, award or other payment. Medicare generally calls this a recovery claim rather than a "medical lien."
The case should be reported appropriately, Medicare's conditional-payment information obtained, and the records reviewed to see whether the listed services actually relate to the injury claim. Unrelated charges can sometimes be challenged. Medicare should not be treated like an ordinary provider lien.
CaliforniaMedi-Cal is different, too
Medi-Cal has a statutory recovery system. When it has paid for accident-related treatment and the injured person later recovers from a responsible third party, the California Department of Health Care Services may seek reimbursement for related services. There are specific procedures for reporting the claim, obtaining payment information, determining the lien, and requesting reductions where appropriate. Medi-Cal's recovery is governed by its own framework, not by Civil Code § 3040.
There is also a timing issue. The DHCS process can involve obtaining payment information after settlement because providers may have additional time to submit claims to Medi-Cal. It is therefore important to determine the status of a Medi-Cal claim before agreeing to a settlement, and to understand that the final reimbursement figure may not be available immediately.
Your own policyMed-Pay
Many people do not realize their own auto policy may include Medical Payments Coverage, or Med-Pay, which can pay certain accident-related medical expenses subject to the policy's terms and limits. It is worth checking the policy.
Med-Pay can be particularly useful because it may provide money for medical expenses while the liability claim is still being investigated. Depending on the policy and applicable law, the auto insurer may have reimbursement rights if the injured person later recovers, so it is not "free money." In many situations, though, using available Med-Pay can make sense because it may avoid the personal obligation that comes with an unpaid provider lien. The actual policy should be reviewed before assuming what the insurer can recover.
The Settlement Number Is Not the Number You Keep
This may be the most important concept on this page. Whether a given settlement offer is a good one cannot be answered from the headline figure alone. The gross settlement is only the starting point.
- Gross settlement
- minus attorney's fees
- minus case costs
- minus medical bills
- minus provider liens
- minus health-plan reimbursement claims
- minus Medicare, Medi-Cal and Med-Pay reimbursement, where applicable
- Net recovery to the client
The same gross settlement can produce a very different financial result depending on the fees, costs and reimbursement claims attached to the case. Change any one of those pieces and the net changes, sometimes dramatically. A large gross figure is not automatically a cause for celebration until the pieces underneath it have been identified and calculated.
A person should be cautious about accepting a settlement simply because the gross number sounds large. The right question is not "how much is the settlement?" but "how much will actually be left after everything that legitimately needs to be paid is accounted for?" The Settlement Offers guide and Case Value page cover evaluation more broadly.
Before Accepting a Settlement
If an offer has been made, get the numbers together.
- Request current statements from the hospital and providers
- Find out what was originally billed
- Find out what was actually paid
- Ask whether any portion was written off or accepted as payment in full
- Ask whether the health plan has asserted a reimbursement or subrogation claim, and whether a recovery company is handling it
- For lien treatment, get the current balance directly from the provider rather than assuming it
- If Medicare is involved, get the current recovery amount and review the claims
- If Medi-Cal is involved, find the status of the DHCS claim and process
- Review the attorney fee agreement carefully; the written agreement controls, including whether terms change if litigation is required
Then add everything together. If a lien balance has become unusually large, that is part of the financial picture too.
Don't Ignore the Bills
One of the worst approaches is to stop opening medical bills because someone else caused the accident. The bills do not disappear. Ignoring them can create collection problems and make it harder to determine what is actually owed. Keep copies of bills, insurance statements, lien agreements, payment records and correspondence.
Medical records are not only a financial matter. They can also become important evidence about the injury itself. The defense may examine timing, complaints, prior conditions, findings, gaps and consistency with the claimed injuries. A large bill does not automatically mean a more valuable case, and a small bill does not mean the injury was minor. Bills are an important piece of the puzzle, but not the whole puzzle. See Evidence & Documentation for how records fit the larger picture.
Common Mistakes With Bills and Liens
MistakeAssuming the other insurer will pay everything
The liability carrier may dispute the treatment, the amount of the bills, causation, or the value of the claim.
MistakeAssuming health insurance means the bills are free
Health insurance may pay the provider, but the plan may later have reimbursement rights.
MistakeTreating a lien like free care
A lien generally postpones payment. It does not necessarily eliminate the obligation.
MistakeIgnoring medical bills
Do not throw bills away because someone else caused the accident.
MistakeAssuming every lien has the same statutory limit
Civil Code § 3040 applies to certain liens, not every medical lien.
MistakeSettling without knowing the numbers
A settlement should not be evaluated by its gross amount alone.
MistakeIgnoring a growing lien balance
If treatment is on a lien, keep track of what is being charged. A growing lien can significantly affect the eventual net recovery.
MistakeAssuming a big bill means a big case
The defense may challenge the reasonableness, necessity, causation, duration, or cost of treatment.
MistakeNot reviewing the fee agreement
Know how attorney fees are calculated and whether the arrangement changes if litigation begins.
When Legal Guidance Can Be Particularly Helpful
Not every claim requires an attorney. A straightforward claim with minor injuries, clear liability, limited treatment and adequate insurance may sometimes be handled without one. The financial picture becomes more complicated with substantial bills, medical liens, Medicare or Medi-Cal, disputed liability, prior conditions, multiple policies, uninsured or underinsured motorist coverage, ERISA plans, or a substantial offer.
Lien and reimbursement issues can also matter when an attractive-looking settlement leaves little after everyone else is paid. The question is not only whether a larger gross settlement can be negotiated, but what the client will actually receive once the pieces are put together. See Do I Need a Personal Injury Lawyer?
Frequently Asked Questions
Does the other driver's insurance company pay my medical bills?
Usually, the other driver's insurance company does not simply pay your medical bills as they arrive. The liability insurer investigates the personal injury claim and may dispute whether treatment was necessary, whether it was related to the accident, how long treatment continued, or whether the charges are reasonable. Medical expenses may instead be paid initially through health insurance, Medical Payments Coverage, Medicare, Medi-Cal, or an arrangement with a medical provider.
Do I have to pay medical bills if someone else caused my accident?
Generally, your obligation to your medical provider is separate from your claim against the person who caused the accident. The fact that another person may ultimately be legally responsible for your damages does not automatically relieve you of your obligation to your doctor or hospital. Medical bills should not simply be ignored while waiting for a personal injury claim to resolve.
Is treatment on a medical lien free?
No. Treatment on a medical lien generally means that payment has been deferred. It does not necessarily mean the medical care is free or that the bill disappears if the personal injury claim is unsuccessful. The written lien agreement is important because it determines the patient's obligations.
Does my health insurance company get paid back from my settlement?
It may. Depending on the type of health plan and applicable law, a health insurer or health plan may have a right to reimbursement if you recover money from the person responsible for your injuries. The amount and legal basis of the claim can vary, so the existence and amount of a reimbursement claim should be determined before evaluating a settlement.
Does Medicare have to be repaid from a personal injury settlement?
Medicare may have a right to reimbursement for accident-related conditional payments if the injured person later receives a settlement, judgment, award, or other recovery. Medicare has its own federal procedures for identifying and resolving these claims.
Does Medi-Cal have a lien on my personal injury settlement?
Medi-Cal may seek reimbursement for accident-related medical services that it paid for when an injured person later receives a recovery from a responsible third party. Medi-Cal has its own California statutory and administrative procedures, which are different from ordinary medical-provider liens.
What is the Howell rule in California personal injury cases?
The California Supreme Court's decision in Howell v. Hamilton Meats & Provisions, Inc. addresses recovery of past medical expenses when a medical provider accepts a lesser amount as payment in full through an agreement with a private health insurer. In that circumstance, the plaintiff generally cannot recover the portion of the bill that was written off and never became the plaintiff's obligation.
Does a $20,000 medical bill mean I have $20,000 in medical damages?
Not necessarily. The amount originally billed by a medical provider is not always the amount that was actually paid or remains owed. Insurance contracts, negotiated rates, write-offs, liens, and other circumstances can affect the amount that is relevant when evaluating past medical expenses.
What is Med-Pay?
Med-Pay, or Medical Payments Coverage, is automobile insurance coverage that may pay certain accident-related medical expenses regardless of fault, subject to the policy's terms and limits. Depending on the circumstances, the insurer may have reimbursement rights if the injured person later recovers money from the responsible party.
Can a medical lien be negotiated?
Sometimes. The ability to negotiate depends on the type of lien or reimbursement claim, the agreement involved, applicable law, and the circumstances of the case. Negotiation of medical balances and reimbursement claims can sometimes affect the client's final recovery.
Is a $100,000 personal injury settlement a good settlement?
There is no way to answer that question based solely on the $100,000 figure. Attorney fees, case costs, medical bills, medical liens, health-insurance reimbursement, Medicare, Medi-Cal, Medical Payments Coverage, and other obligations may affect the amount the injured person ultimately receives. The important number is the net recovery, not simply the gross settlement.
What should I know before accepting a personal injury settlement?
Before accepting a settlement, you should understand the medical bills, what was actually paid, what remains owed, and whether anyone has a reimbursement or lien claim. You should also know the attorney fees and case costs and determine what will actually remain after those obligations are paid. Know your numbers before agreeing to the settlement.
The Bottom Line: Know Your Numbers
- What was billed
- What was actually paid
- What was written off
- What your health insurer may claim
- Whether Medicare or Medi-Cal has a claim
- What providers claim under lien agreements
- What Med-Pay may have paid
- The attorney fee and case costs
Then determine what will actually be left. A large headline settlement means very little if you do not know what happens to it after the settlement is funded. The gross settlement is the headline. The net recovery is the number that matters.
