MedPay, Medical Liens & Subrogation After an Arizona Crash
Medical payments coverage can provide immediate first-party benefits after a crash, but the payment trail does not end when a medical bill is paid. Arizona has distinct rules governing MedPay insurer liens, health-care-provider liens, health-plan reimbursement rights and the distribution of a later liability settlement.
MedPay is first-party automobile insurance
Medical payments coverage, commonly called MedPay, is automobile insurance that pays covered medical expenses under the terms and limits of the insured's own policy.
It is different from bodily-injury liability insurance. Liability coverage protects an insured against claims asserted by others. MedPay is a first-party benefit available to persons who satisfy the policy's coverage terms.
Your policy
The claim is made under an applicable automobile policy rather than waiting for a liability claim against another driver to resolve.
Coverage-based payment
MedPay generally concerns covered medical expenses arising from an automobile accident, subject to the policy language and limit.
Fault may not control payment
Whether MedPay is available is primarily a coverage question, distinct from proving the other driver's tort liability.
Arizona's MedPay reimbursement rule begins above $5,000
Arizona historically prohibits the assignment or subrogation of a personal-injury claim unless a statute creates an exception. The Arizona Supreme Court applied that principle to automobile medical-payment reimbursement provisions in cases including State Farm v. Knapp and Allstate v. Druke.
Arizona later enacted a specific statutory MedPay lien in A.R.S. § 20-259.01(J).
| Example | MedPay paid | Maximum amount potentially within § 20-259.01(J) |
|---|---|---|
| Example 1 | $5,000 | $0 |
| Example 2 | $7,500 | Amount above $5,000: $2,500 |
| Example 3 | $10,000 | Amount above $5,000: $5,000 |
| Example 4 | $25,000 | Amount above $5,000: $20,000 |
These examples identify the statutory ceiling potentially subject to the MedPay lien mechanism. They do not establish that a particular insurer has actually perfected or is entitled to collect that amount.
The MedPay insurer must satisfy the statutory lien procedure
A.R.S. § 20-259.01(J) does more than authorize a lien. It establishes specific steps for creating and perfecting it.
60-day requirement
The insurer must record the required lien statement in the county where the accident occurred within 60 days after issuing a MedPay payment exceeding $5,000.
Five-day mailing requirement
Within five days after recording the lien, the insurer must mail the required copy to the insured and the identified allegedly responsible parties and carriers.
Fair and equitable compromise
The statute expressly directs the insurer to compromise its MedPay lien in a fair and equitable manner.
Lien release
Once the lien is satisfied, the lienholder must issue and record a release within the period required by the statute.
Health-care-provider liens are a different system
Arizona health-care providers may have statutory lien rights under A.R.S. §§ 33-931 through 33-937. These are separate from an automobile insurer's MedPay lien.
Under the current version of A.R.S. § 33-931, a provider lien may extend to appropriate liability or indemnity claims arising from the injuries for which treatment was provided.
This is an important change from prior Arizona law. Older cases interpreting earlier statutory language must therefore be read against the current statute rather than treated as a statement of the present provider-lien rule.
Provider lien perfection
A.R.S. § 33-932 establishes recording and notice requirements for health-care-provider liens. The timing and requirements differ depending on the type of provider.
Arizona now requires fair and equitable compromise of qualifying provider liens
A.R.S. § 33-937 requires interested parties to compromise qualifying liens or assignments under § 33-931 so that settlement is fair and equitable to all parties.
The statute identifies factors to consider, including:
- the nature and extent of the injury;
- available liability insurance or indemnity;
- payments already received by the provider;
- the nature and complexity of the medical services;
- the provider's customary charges;
- the total third-party recovery;
- other valid liens and their priority;
- attorney fees and litigation costs;
- reductions accepted by other claimants;
- other valid reimbursement or subrogation claims; and
- other relevant circumstances.
The one-third provider-lien rule requires careful reading
Current A.R.S. § 33-931 contains a provision exempting one-third of certain third-party judgments, settlements or awards from a statutory provider lien or assignment.
But the same statute contains specific exceptions affecting whether that protection applies, including circumstances involving uncovered services, out-of-network providers, persons without health insurance, and written elections not to use available health coverage.
Health insurance creates a separate reimbursement analysis
A medical bill can pass through several different payment systems. Each system may have different reimbursement rights.
| Payment source | Primary issue to investigate |
|---|---|
| Arizona automobile MedPay | Policy coverage plus the limited statutory insurer lien under A.R.S. § 20-259.01(J). |
| Private health insurance | Plan language, state insurance law and any applicable reimbursement or subrogation provisions. |
| ERISA plan | Determine whether the plan is self-funded and examine the actual governing plan documents and federal reimbursement provisions. |
| Medicare / Medicare Advantage | Federal Medicare secondary-payer and reimbursement law may create rights independent of Arizona's common-law anti-subrogation rule. |
| AHCCCS / Medicaid | Arizona and federal Medicaid recovery statutes can create independent lien and reimbursement rights. |
| Workers' compensation | Arizona workers' compensation statutes contain separate third-party recovery and lien rules. |
| Health-care provider | Determine whether a valid statutory lien exists under A.R.S. §§ 33-931–33-937 and what recovery it actually attaches to. |
Do not calculate the client's net recovery from the gross settlement alone
A settlement can look adequate until all valid reimbursement claims, liens, unpaid medical balances, fees and costs are identified.
Before final settlement, build a distribution ledger showing:
- gross settlement amount;
- attorney fees, if any;
- litigation costs;
- MedPay benefits paid;
- any properly perfected MedPay insurer lien;
- provider balances;
- recorded provider liens;
- health-insurance payments;
- Medicare, AHCCCS or other governmental claims;
- ERISA or other plan reimbursement claims;
- negotiated reductions; and
- the claimant's actual net recovery.
Citizen workflow for Arizona medical payments and liens
Bottom line
Arizona MedPay can provide valuable first-party medical benefits before a liability claim is resolved. But reimbursement rights are not automatic. Arizona limits the automobile insurer's statutory MedPay lien to qualifying payments above $5,000 and imposes perfection and compromise requirements. Provider liens operate under a different statutory system, and current Arizona law expressly excludes MedPay, UM, UIM and health- insurance proceeds from the ordinary provider lien. Identify every payment source, verify every claimed lien, determine exactly what recovery it reaches, negotiate required reductions, and calculate the claimant's net recovery before settlement funds are distributed.
