CALIFORNIA GUIDE 21

MedPay & Subrogation

Paying the medical bills is only the first half of the problem. After a California crash, an auto insurer, health plan, hospital, Medicare, Medi-Cal or workers’ compensation carrier may later seek money from the injury recovery. Each reimbursement system has different rules. The first task is to identify who actually paid each bill and what legal authority, if any, permits that payer to be reimbursed.

What Is MedPay?

MedPay is optional first-party medical coverage under the auto policy

MedPay can pay qualifying accident-related medical expenses without waiting for the liability dispute against the other driver to be resolved.

Your own auto coverage

The claim is presented under the MedPay provision of an applicable automobile policy rather than against the negligent driver’s liability coverage.

Fault need not be proven first

California cases describe MedPay as no-fault coverage intended to provide an additional source for qualifying medical expenses.

Not mandatory California coverage

Unlike mandatory liability insurance and California’s statutory UM offer requirement, California does not require every auto policy to contain MedPay.

The policy answers who and what MedPay covers

There is no single California statutory MedPay form. Coverage is contractual.

Who is insured?

Determine whether the provision reaches the named insured, resident family, passengers, pedestrians or other occupants under the actual form.

Which accident?

Vehicle occupancy, use, ownership and other policy definitions can determine whether a particular injury falls within coverage.

Which medical expense?

Determine whether the expense was caused by the accident and satisfies the policy’s reasonable-and-necessary requirements.

When must the expense be incurred?

Policy forms may contain time limitations. Do not assume all MedPay policies use the same period.

Receiving MedPay does not necessarily mean the money can never be reclaimed

Automobile policies commonly contain reimbursement provisions addressing a later recovery from the person who caused the injury.

The made-whole doctrine protects the insured’s priority to recover the actual loss

California’s default equitable rule generally puts the injured insured ahead of the insurer where the available third-party recovery is not sufficient to compensate the complete loss.

Illustration

The policy can change the default priority—but the language matters

California recognizes that an insurance contract can alter the made-whole default if it does so clearly and specifically.

Generic recovery clause

Language merely transferring recovery rights may not necessarily establish an insurer’s priority before the insured is made whole.

Express priority clause

More specific language stating that reimbursement is owed regardless of whether the insured has been fully compensated can materially alter the analysis.

Made whole and common fund solve two different problems

Made-whole and common-fund doctrines address different reimbursement questions.
Doctrine	Question
Made whole	Has the insured been fully compensated for the damages caused by the injury before the insurer receives reimbursement?
Common fund	If the insurer receives money because the insured and counsel created the recovery, what proportional share of attorney fees and recovery costs should the insurer bear?

MedPay can also interact with uninsured-motorist coverage

California Insurance Code §11580.2(e) allows an automobile UM policy or endorsement to provide that damages recoverable for purposes of UM coverage are reduced by valid and collectible auto medical-payment insurance paid or due to the insured.

Underinsured-motorist claims also require the separate rules in §11580.2(p). Read the entire policy and statute before applying an offset.

A California health-plan lien follows a different statutory structure

Civil Code §3040 limits specified liens asserted by California-regulated health insurers, health-care service plans, medical groups and independent practice associations.

Civil Code section 3040 rules for qualifying California-regulated health-plan liens.
§3040 issue	General rule
Noncapitated treatment	Maximum generally begins with amounts actually paid to treating providers plus reasonable lien-perfection costs.
Capitated treatment	Statute generally uses 80% of usual and customary charges for comparable noncapitated services in the geographic region.
Claimant has attorney	Lien cannot exceed the lesser of the statutory calculation or one-third of the money due under settlement, judgment or compromise.
No attorney	Lien cannot exceed the lesser of the statutory calculation or one-half of the recovery.
Comparative-fault judgment	A qualifying special finding reduces the lien by the same comparative-fault percentage.
Attorney fees / costs	Section 3040 expressly requires pro rata common-fund reduction for reasonable fees and costs.

Ask whether an employer health plan is insured or self-funded

That distinction can completely change the reimbursement analysis.

Insurance carrier bears the risk

State insurance regulation can have greater application to an insured health plan, subject to the complete federal and state framework.

Employer plan bears the benefit risk

Federal ERISA preemption can displace state-law restrictions that otherwise might limit reimbursement.

Hospital liens are not ordinary health-insurer liens

California’s Hospital Lien Act appears at Civil Code §§3045.1–3045.6.

Qualifying hospital services

Section 3045.1 addresses emergency and ongoing hospital or qualifying affiliated-facility services caused by an accident or wrongful act.

Underlying debt required

Parnell holds that the lien is based upon an actual creditor-debtor relationship between the hospital and patient.

Notice required

Section 3045.3 requires the hospital to give prescribed written notice to known liable parties and their known liability insurers before payment.

Recovery limit

Section 3045.4 limits satisfaction from the tort recovery generally to what can be paid from 50% of the recovery after prior liens, subject to the complete statutory scheme.

Medicare is a federal recovery system

Federal Medicare Secondary Payer law can make Medicare secondary where automobile liability insurance, no-fault insurance or another qualifying primary plan has payment responsibility.

Before final distribution

identify Medicare beneficiary status
report the liability claim where required
obtain conditional-payment information
audit accident-related charges
dispute unrelated charges where appropriate
obtain final recovery information
resolve before distributing protected proceeds

Medi-Cal uses its own California third-party recovery statutes

Welfare and Institutions Code §§14124.70–14124.94 govern California’s Medi-Cal third-party liability and reimbursement system.

Medical allocation

Section 14124.76 limits recovery from the beneficiary’s tort claim to the portion of the recovery representing payment for medical expense or medical care provided for the beneficiary.

Attorney-fee reduction

Section 14124.72 provides a statutory reduction when the beneficiary prosecutes the third-party claim and has personal liability for fees and costs, including a 25% attorney-fee component.

A work-related crash can add workers’ compensation reimbursement

When an employee receives workers’ compensation and also recovers from a responsible third party, Labor Code §§3852–3856 create a separate recovery system.

One medical bill can appear in several reimbursement ledgers

Settlement mistakes occur when every payer’s demand is treated as a separate valid debt without reconciling who actually paid what.

Common medical-payment and reimbursement claimants and the primary legal source to investigate.
Payer / claimant	Primary legal source to investigate
Auto MedPay carrier	Auto policy + made-whole/common-fund California case law.
California regulated health insurer / plan	Plan contract + Civil Code §3040 where applicable.
Self-funded employer plan	ERISA + complete plan document + federal authority.
Hospital	Underlying patient debt + Civil Code §§3045.1–3045.6.
Medicare	Federal Medicare Secondary Payer statutes/regulations + CMS process.
Medi-Cal	Welfare and Institutions Code §§14124.70 et seq.
Workers’ compensation	Labor Code §§3850–3865.
Medical provider	Contract, assignment or legally effective provider lien, if any.

Common mistakes

“MedPay is liability insurance.”

No. MedPay is first-party medical-expense coverage and generally operates without requiring a liability determination.

“California requires every auto insurer to provide MedPay.”

No. California cases expressly recognize that MedPay is not mandatory coverage.

“If MedPay paid $5,000, I always owe the insurer $5,000 from settlement.”

No. Analyze the reimbursement clause, made-whole doctrine and common-fund reduction.

“Attorney fees are added to damages to decide whether I was made whole.”

Not under 21st Century. Attorney-fee allocation is handled separately through proportional common-fund principles.

“Made whole and common fund are the same rule.”

No. One determines reimbursement priority; the other allocates the expense of creating the recovery.

“Civil Code §3040 controls every health lien.”

No. It expressly excludes hospital liens, Medi-Cal and workers’ compensation and recognizes federal preemption.

“A hospital can lien the gross chargemaster bill even after accepting health insurance as payment in full.”

Not under Parnell. The Hospital Lien Act requires an underlying patient debt.

“Every hospital bill automatically creates an enforceable lien.”

No. The Hospital Lien Act contains statutory notice and other requirements.

“A self-funded employer plan follows the same California cap as private health insurance.”

Not necessarily. ERISA preemption can materially change the analysis.

“Made whole and common fund always override a self-funded ERISA plan.”

No. McCutchen makes the governing written plan terms central. Equitable doctrines can fill gaps but ordinarily cannot contradict clear reimbursement language.

“Medicare paid the bill, so settlement distribution is complete.”

No. Medicare can make conditional payments and later assert federal recovery rights.

“Medi-Cal uses the §3040 one-third cap.”

No. Medi-Cal has its own statutory third-party recovery system.

“A lien letter proves the amount is correct.”

No. Audit legal authority, payments, contractual adjustments, accident relationship, caps and reductions.

California authority map

Leading California MedPay reimbursement decision. Confirms that the made-whole rule applies in the auto MedPay context and distinguishes made-whole analysis from proportional attorney-fee allocation under common-fund principles.

Applies the made-whole doctrine to automobile MedPay reimbursement and explains that clear and specific policy language can alter the default equitable priority.

Important California made-whole authority establishing the insured’s priority to full compensation before insurer subrogation absent sufficiently clear contrary contractual language.

Recognizes contractual reimbursement from settlement proceeds while distinguishing the impermissible assignment of the insured’s personal injury cause of action.

Describes automobile MedPay as optional first-party, no-fault coverage for qualifying medical expenses and recognizes that California does not statutorily require the coverage.

Permits a UM policy or endorsement to provide for reduction of recoverable UM damages by amounts paid or due under valid and collectible automobile medical-payment insurance.

Establishes payment-based lien limits, one-third / one-half recovery caps in specified cases, comparative-fault treatment and an express common-fund fee-and-cost reduction for covered health-plan liens.

Establishes the important ERISA distinction permitting broad federal preemption of state insurance regulation as applied directly to a self-funded employee welfare benefit plan.

Holds that clear ERISA reimbursement plan terms govern and cannot be overridden by general equitable made-whole or common-fund principles; where the plan is silent about attorney fees, common fund supplies the default allocation rule.

Explains the equitable-remedy limits of ERISA §502(a)(3) and the significance of specifically identifiable settlement funds. It is a remedy rule, not permission to disregard a valid plan reimbursement duty.

Creates a lien for qualifying reasonable and necessary hospital / affiliated-facility charges against recovery arising from the accident or wrongful act.

Requires the prescribed written lien notice to known liable parties and their known liability insurers before payment of the injury recovery.

Protects a properly noticed hospital lien against settlement payment made without satisfying the amount recoverable from up to 50% of the proceeds after prior liens, subject to the full statutory terms.

Holds that a Hospital Lien Act lien requires an underlying debt owed by the patient; without that debt the hospital cannot use the statute to obtain additional tort proceeds.

Explains that a hospital-type statutory lien based on the patient’s debt is not reduced under the ordinary common-fund doctrine merely because the patient’s attorney created the tort recovery.

Explains that hospital-lien rights are limited by the patient’s actual indebtedness and applicable contractual payment arrangements.

Holds that merely delivering the injured person or counsel a joint-payee check naming the hospital does not itself constitute payment satisfying a properly noticed Hospital Lien Act lien.

Provides statutory treatment of Medi-Cal reimbursement including an attorney-fee and litigation-cost reduction when the beneficiary prosecutes the third-party claim.

Limits Medi-Cal recovery to the portion of the tort recovery representing payment for medical expense or medical care provided for the beneficiary and establishes a process for resolving allocation disputes.

Medicare can make conditional payments where liability, no-fault or another primary payer does not pay promptly and can later recover when settlement, judgment, award or other payment establishes responsibility.

Establishes allocation of litigation expenses, attorney fees and employer reimbursement/lien rights from qualifying third-party recoveries.

Frequently asked questions

It is optional first-party automobile coverage that generally pays qualifying reasonable and necessary accident-related medical expenses under the terms and limit of the policy without requiring proof that another driver caused the accident.

No. California appellate authority recognizes that automobile MedPay is not statutorily mandatory.

Potentially yes. MedPay is designed to provide medical-payment funds without waiting for the fault-based liability claim to be resolved. Reimbursement consequences should be separately reviewed.

Potentially. Review the policy’s reimbursement clause, California’s made-whole doctrine and the insurer’s proper contribution to attorney fees and recovery costs.

It is the default equitable principle that generally gives the insured priority over the insurer’s reimbursement claim until the insured has been fully compensated for the loss, absent effective policy language changing that rule.

California recognizes contractual modification where the language clearly and specifically gives the insurer reimbursement priority even before the insured is fully compensated.

21st Century holds that attorney fees are not simply treated as part of the insured’s damages in the made-whole calculation. Attorney-fee sharing is addressed separately through proportional common-fund principles.

It generally prevents a reimbursement claimant from receiving the benefit of a recovery created through the injured person’s legal effort without paying an appropriate proportional share of the cost of producing that recovery.

Yes. Insurance Code §11580.2(e) permits a California UM policy to contain an authorized offset for valid and collectible auto MedPay amounts paid or due. The actual policy and complete statute must be reviewed.

For a lien governed by Civil Code §3040, the amount can be limited by the insurer’s actual payment, statutory percentage caps, comparative fault in a qualifying judgment and common-fund attorney-fee/cost reductions. But first determine whether §3040 actually applies.

No. Section 3040 expressly excludes Hospital Lien Act liens, Medi-Cal and workers’ compensation and may also be affected by federal ERISA preemption.

It is generally an employer benefit plan in which the plan or employer bears the financial risk of paying benefits rather than simply purchasing a conventional health-insurance policy. Federal ERISA rules can materially affect reimbursement rights.

No. Under U.S. Airways v. McCutchen, clear governing plan terms generally control an ERISA reimbursement claim. Equitable doctrines may fill contractual gaps, including a gap concerning attorney-fee allocation, but ordinarily cannot override unambiguous contrary language.

Not automatically. Under Parnell, a California Hospital Lien Act claim requires an underlying debt owed by the patient. Contractual arrangements showing the hospital accepted payment in full can therefore be critical.

The Hospital Lien Act contains a specific recovery structure, including the §3045.4 limitation tied generally to 50% of the recovery after prior liens. The validity and amount of the hospital’s underlying debt must also be established.

Medicare can make conditional accident-related payments and later assert federal recovery rights against qualifying settlements, judgments, awards or other payments. Obtain and audit the CMS recovery information.

No. Medi-Cal has a separate California statutory third-party recovery system under Welfare and Institutions Code §§14124.70 et seq.

Workers’ compensation can pay benefits and later assert statutory reimbursement rights against a responsible third party. Labor Code §§3852–3856 require a separate analysis.

Reimbursement exposure should be identified before final settlement so the net recovery can be evaluated. Certain federal or statutory claims also require protection before settlement funds are finally distributed.

Ask for the legal basis, contract or statute, complete payment ledger, accident-related charges, lien/perfection evidence, calculation, attorney-fee reduction, applicable cap and final payoff amount.

Guide 22 → Settlement & Release

Do not ask only, “How much is the lien?” Ask, “Why is this money legally owed?”

Identify who paid every medical bill. Obtain the policy, plan or statute creating any reimbursement right. Reconcile the payment ledger. Apply the correct made-whole rule, common-fund reduction, statutory cap, federal preemption and comparative-fault rule. Obtain a final payoff in writing before distributing the settlement. A reimbursement demand is the beginning of the audit—not the end of it.
