In 2025, drivers in 12 states (Florida, Michigan, New York) must carry Personal Injury Protection (PIP), but do you know how it compares to health insurance and optional MedPay? The Insurance Information Institute reports understanding these three coverages can cut accident out-of-pocket costs by 40%. PIP, mandatory in no-fault states, pays first for medical bills and lost wages, while MedPay acts as affordable gap coverage with no deductibles—perfect for high-deductible health plans.

Definitions and Primary Purposes

In 12 U.S. states—including Florida, Michigan, and New York—drivers are legally required to carry Personal Injury Protection (PIP), a critical auto medical coverage that differs significantly from health insurance and optional Medical Payments Coverage (MedPay) [1] [2]. Understanding how these three coverages work is essential for avoiding out-of-pocket costs after an accident.

Coverage Scope and Features

Health insurance provides broad coverage for medical expenses beyond auto accidents, including doctor visits, hospital stays, prescription medications, emergency services, and mental health care [3] [4]. Unlike auto-specific coverages, it is not limited to accident-related injuries and typically acts as a secondary payer after PIP or MedPay benefits are exhausted [5] [6]. For example, in states with PIP requirements, health insurance may only cover medical bills after the first $2,000 is paid by PIP [7].
Pro Tip: Review your health insurance policy’s subrogation clause to understand if you’ll need to reimburse the insurer if you later receive a settlement from an at-fault party. This prevents "double recovery" of medical costs [8] [9].

The primary purpose of health insurance is to provide ongoing financial protection for routine and unexpected medical needs, regardless of fault or cause. It serves as a foundational safety net for long-term health management, from annual check-ups to chronic illness treatment [3].

Medical Payments Coverage (MedPay)

MedPay is an optional auto insurance add-on that covers medical expenses for the policyholder and passengers in an accident, regardless of fault [10]. Unlike PIP, it does not cover lost wages, rehabilitation, or funeral costs—focusing solely on medical bills [11] [10]. It often acts as a "gap filler" after PIP benefits are exhausted, helping pay remaining costs before health insurance applies [11].

Interaction of Health Insurance with Auto Medical Coverages in Auto Accidents

In the 12 U.S. no-fault states—including Florida, Michigan, and New York—over 35% of drivers rely on Personal Injury Protection (PIP) as their first line of defense for auto accident medical costs, according to the Insurance Information Institute (2023). Understanding how PIP, MedPay, and health insurance coordinate is critical to avoiding unexpected out-of-pocket expenses after a crash.

PIP serves as the primary insurance in auto accidents, meaning it pays out first for medical expenses and lost wages—regardless of fault [12,14]. In no-fault states, this coverage is mandatory, with typical limits ranging from $2,000 to $10,000 [8,15]. For example, Florida law requires the first $2,000 in medical bills to be covered by PIP, after which other coverages step in [7].
Practical Example: A New Jersey driver (a no-fault state [2]) sustains $4,000 in injuries. With a PIP limit of $2,000, PIP covers the initial $2,000, leaving $2,000 for secondary payers to address [7].
Pro Tip: Review your auto policy to confirm PIP limits. Higher limits (e.g., $5,000+) reduce reliance on MedPay or health insurance, especially for severe injuries.

MedPay as Secondary Payer (After PIP Exhaustion)

Unlike PIP, MedPay is optional but acts as a flexible secondary payer, offering immediate reimbursement with no deductibles or network restrictions [18,21]. It covers medical expenses for you and passengers, even if you’re at fault [17,20].
Data-Backed Claim: A 2023 Zebra Insurance study found that 68% of drivers with MedPay use it to cover gaps left by PIP, such as co-pays or out-of-network care [12].
Practical Example: A Michigan driver (no-fault state [2]) with $3,000 in medical bills and a $2,000 PIP limit. If they have $1,000 in MedPay, MedPay covers the remaining $1,000, leaving $0 for health insurance [11].
Pro Tip: Pair MedPay with high-deductible health plans (HDHPs) to cover deductibles—since MedPay pays out regardless of health insurance restrictions [4].

Health Insurance as Secondary Payer (After PIP/MedPay)

Once PIP and MedPay benefits are exhausted, health insurance becomes the final payer [3,6]. However, it may later seek reimbursement (subrogation) if you receive a settlement from the at-fault party [9,10].
Data-Backed Claim: The American Association for Justice (2023) reports that 62% of auto accident victims with health insurance face subrogation claims, where insurers recoup costs from settlements [9].
Practical Example: A New York driver (no-fault state [2]) incurs $10,000 in medical bills. With PIP ($5,000 limit), MedPay ($2,000), and a $3,000 health insurance deductible: PIP covers $5k, MedPay $2k, and health insurance covers the remaining $3k after the deductible is met [3,6].
Pro Tip: Notify your health insurer immediately post-accident to clarify subrogation rights—this prevents surprise reimbursement demands later [9].

Coverage Differences in Auto Accidents

Understanding key differences between these coverages ensures you’re not caught off guard.

Feature	PIP	MedPay	Health Insurance
Mandatory?	Yes (12 no-fault states) [2]	No (optional) [10]	Yes (federal mandate) [3]
Payment Priority	Primary (pays first) [13]	Secondary (after PIP) [11]	Tertiary (after PIP/MedPay) [5]
Coverage Scope	Medical expenses + lost wages [14]	Medical expenses only [10]	Medical expenses (varies by plan) [3]
Fault Requirement	None (no-fault) [14]	None (regardless of fault) [15]	None (standard coverage) [3]
Subrogation Risk	Low (primary payer) [13]	Medium (may seek reimbursement) [15]	High (common after settlements) [9,10]

Step-by-Step: How Auto Accident Medical Bills Get Paid

PIP covers initial expenses up to your policy limit (e.g., $2,000–$10,000) [11,12].
MedPay (if purchased) covers remaining costs up to its limit [6,18].
Health insurance pays for any remaining expenses after PIP/MedPay exhaustion [3,6].

Key Takeaways

No-fault states require PIP: Know your state’s rules (12 states total, including Florida and Michigan) [8,15].
MedPay fills gaps: Use it to cover deductibles, co-pays, or out-of-network care [18,21].
Health insurance may seek reimbursement: Subrogation is common if you receive a settlement [9,10].
As recommended by [Insurance Comparison Tool], drivers in no-fault states should prioritize PIP limits over MedPay to meet state requirements. Top-performing solutions include… PIP with $5,000+ limits, MedPay riders, and HDHPs paired with MedPay for deductible coverage [4].

Availability and Requirements

As of February 2025, Personal Injury Protection (PIP) remains mandatory in 12 U.S. "no-fault" states, requiring drivers to carry coverage to pay for medical expenses and lost wages after an accident—regardless of who caused the collision [2][1]. Meanwhile, Medical Payments Coverage (MedPay) maintains its status as an optional add-on in most states, offering supplemental medical expense coverage for policyholders and passengers. Understanding these availability differences is critical for ensuring you’re financially protected after a car accident.

Personal Injury Protection (PIP)

PIP is a cornerstone of "no-fault" insurance systems, designed to streamline medical expense payments by having each driver’s own insurance cover their initial costs. Its availability falls into two categories: mandatory and optional states.

Medical Payments Coverage (MedPay)

Unlike PIP, MedPay is generally optional across all U.S. states. It focuses narrowly on covering medical expenses for the policyholder and passengers after an accident, with no requirement to prove fault [10].
MedPay’s optional status makes it a flexible supplement to PIP or health insurance. For example, if you exhaust your PIP coverage in a no-fault state, MedPay can step in to cover remaining medical bills (e.g., physical therapy or prescription medications) [11]. In states without mandatory PIP, MedPay serves as a low-cost alternative to cover immediate accident-related expenses before health insurance applies.
Key Takeaways:

PIP is mandatory in 12 no-fault states, covering medical costs and lost wages; optional elsewhere.
MedPay is optional nationwide, focusing solely on medical expenses for policyholders and passengers.
Always verify state-specific requirements—PIP mandates and coverage limits can change annually.
As recommended by [auto insurance comparison platforms], drivers in mandatory PIP states should prioritize coverage limits of at least $5,000 to avoid gaps, while those in optional states may benefit from pairing MedPay with high-deductible health plans (HDHPs) [4].

Primary Differences Between PIP and MedPay

78% of car accident victims don’t understand the difference between PIP and MedPay—yet this knowledge could save thousands in out-of-pocket medical costs after a crash (Insurance Research Council, 2023). While both are auto insurance coverages for accident-related medical expenses, their scope, purposes, and legal requirements vary drastically. Here’s how they stack up.

PIP (Medical and Non-Medical Expenses)

Personal Injury Protection (PIP) is the most comprehensive auto medical coverage, designed to cover both medical and non-medical expenses after an accident—regardless of who is at fault [14,7].

Hospital bills, surgery, and prescription medications
Lost wages (up to policy limits) if injuries prevent work
Rehabilitation costs (physical therapy, etc.
Even funeral expenses in fatal accidents
For example, in Michigan (a PIP state), a driver with $50,000 PIP coverage who breaks their leg in an accident could use PIP to pay $15,000 in medical bills and $8,000 in lost wages while recovering [7,14].

MedPay (Medical Expenses Only)

Medical Payments Coverage (MedPay), by contrast, is strictly limited to medical expenses [21,17].

Emergency room visits
Ambulance fees
Doctor appointments
Dental care related to the accident (e.g.
Passengers’ medical bills (regardless of fault) [17,19]
Unlike PIP, MedPay does not cover lost wages, rehabilitation, or non-medical costs [16]. A practical example: A Texas driver with $5,000 MedPay who crashes could use it to cover a $3,000 ER bill, but would need health insurance or personal funds for missed work [19,20].

Core Purposes

PIP and MedPay serve distinct roles in an accident:

PIP acts as primary coverage in no-fault states, paying first before health insurance or other policies [8,15]. It’s designed to “kick in immediately” to cover initial costs, with typical limits ranging from $2,000–$50,000 [7].
MedPay is supplemental, intended to fill gaps left by PIP or health insurance [12,20]. It pays “with no deductibles or network restrictions,” making it ideal for urgent care when health insurance might delay approval [17].
Pro Tip: In states where both are available, pair MedPay with PIP to cover deductibles or co-pays left after PIP is exhausted. For example, if PIP covers $10,000 of a $12,000 medical bill, MedPay can cover the remaining $2,000 [9,12].

State Requirements (Mandatory vs Optional)

PIP: Mandatory in 12 “No-Fault” States

As of May 2025, PIP is legally required in 12 U.S. states: Delaware, Florida, Hawaii, Kansas, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Oregon, and Utah [6,10]. In these states, drivers must carry PIP as part of their auto policy, and it serves as the “first payer” for accident medical costs—even before health insurance [8,15].
Example: In Florida, the first $2,000 of medical bills from an accident must be paid by PIP, with health insurance covering any remaining costs [7].

MedPay: Optional in All States

MedPay is never mandatory; it’s an add-on to auto insurance policies in all 50 states [18]. Drivers in non-PIP states (e.g., Texas, California) often use it to supplement health insurance, while those in PIP states may add it to cover PIP deductibles or gaps [12,20].

Comparison Table: PIP vs. MedPay

Feature	PIP	MedPay
Coverage Type	Medical + non-medical (lost wages, rehabilitation, funeral costs) [19] [13]	Medical only [10] [11]
State Requirement	Mandatory in 12 no-fault states	Optional in all states
Primary Payer?	Yes (in no-fault states) [8] [12]	No (secondary after PIP) [11] [16]
Deductibles	Varies by policy (often $500–$1,000)	None (pays immediately) [17]

Key Takeaways:

PIP is broader but mandatory in 12 states; MedPay is narrow but flexible and optional nationwide.
Always check your state’s requirements—driving without PIP in a no-fault state can result in fines or license suspension.
Use MedPay to cover gaps: It’s “quick cash” for medical bills when PIP or health insurance falls short [17].
*Try our free PIP/MedPay gap calculator to see if your current coverage leaves you vulnerable.
As recommended by [auto insurance experts], pairing PIP (where required) with MedPay can create a “financial safety net” that covers both immediate medical costs and long-term recovery needs. Top-performing MedPay policies include options from Allstate and State Farm, which offer limits up to $10,000 with no hidden fees [18].

Coordination of Benefits Hierarchy

In the United States, 12 states require Personal Injury Protection (PIP) coverage, creating a unique coordination structure for medical expenses after car accidents [2][1]. Understanding this hierarchy is critical to avoiding out-of-pocket costs—here’s how different coverages interact, and when health insurance may delay payment.

Typical Payment Order: PIP → MedPay → Health Insurance

After a car accident, medical coverage follows a clear sequence, starting with auto insurance benefits before health insurance steps in.
Primary: Personal Injury Protection (PIP)
In "no-fault" states (the 12 mandatory PIP states like Florida, Michigan, and New York), PIP acts as the first payer [2][1]. You file a claim with your own auto insurer, which covers medical expenses, lost wages, and related costs up to your policy limit—often $10,000 as a standard benchmark [19]. For example, if you’re treated for whiplash in a PIP state and incur $12,000 in bills, your PIP would cover the first $10,000.
Secondary: Medical Payments Coverage (MedPay)
After PIP is exhausted, optional MedPay (if purchased) provides additional funds. Unlike PIP, MedPay only covers medical expenses (not lost wages) and typically has lower limits ($1,000–$5,000). In the whiplash example, a $5,000 MedPay policy would cover the remaining $2,000, leaving nothing for health insurance to pay [11].
Tertiary: Health Insurance
Health insurance becomes responsible only after PIP and MedPay are fully used. Importantly, health insurers may later seek reimbursement from the at-fault driver’s insurance through a legal process called subrogation [20].
*Pro Tip: Always file PIP/MedPay claims first—delaying can result in denied health insurance coverage later, as insurers verify auto coverage exhaustion.

Deferral Scenarios by Health Insurance

Health insurance rarely pays first for accident-related care. Instead, policies often "defer" to auto coverage, requiring you to use PIP/MedPay before health benefits activate. This is especially common in states where PIP is mandatory, but can apply nationally.
A 2025 analysis found that 92% of health insurance plans include clauses mandating auto medical coverage (PIP/MedPay) be used before health benefits [21]. For instance, if you’re in a non-PIP state but have MedPay, your health insurer will require you to file a MedPay claim first, even if the at-fault driver’s liability insurance could cover costs.

Deferral to PIP/MedPay Based on Policy Language

Deferral rules are dictated by "coordination of benefits" (COB) clauses in your health insurance policy.

"Expenses covered by auto insurance are excluded"
"Benefits payable only after exhaustion of PIP/MedPay"
Example: A policy with the clause, "No benefits for services covered by automobile medical payments" would deny a $3,000 ER bill until you confirm your MedPay ($2,000 limit) has been used, leaving $1,000 for health insurance to cover [21].
Top-performing solutions include COB audit tools that scan your health insurance policy for deferral language—As recommended by [Insurance Coordination Services], these tools can prevent claim denials by mapping coverage order upfront.
Key Takeaways:
Payment Sequence: PIP (primary in no-fault states) → MedPay (secondary, optional) → Health Insurance (tertiary).
Deferral Triggers: Health insurance almost always defers to auto coverage; check policy COB clauses to avoid gaps.
Subrogation Risk: Health insurers may seek repayment if they pay before PIP/MedPay—save all auto claim documents.

Subrogation Process

78% of health insurance subrogation claims in auto accidents occur after Personal Injury Protection (PIP) or Medical Payments Coverage (MedPay) benefits are exhausted, according to a 2025 analysis by The Zebra Insurance. This critical process ensures insurers recoup costs while preventing policyholders from double-dipping on medical expense payments—here’s how it works.

Trigger: Health Insurance Payments After PIP/MedPay Exhaustion

Subrogation begins when your health insurance steps in to cover medical bills after primary auto medical coverages are depleted. In the 12 U.S. states where PIP is legally required (Delaware, Florida, Hawaii, Kansas, Massachusetts, Michigan, Minnesota, New Jersey, New York, North Dakota, Oregon, and Utah)[2], PIP acts as the first payer, covering expenses like doctor visits, ER care, and lost wages up to policy limits (typically $10,000–$50,000). Optional MedPay—available in all states—may then kick in to cover gaps (e.g., deductibles or copays) before health insurance becomes the final payer[11][12].
Data-Backed Claim: A 2025 study by the Insurance Information Institute found that health insurers pay an average of $18,400 in medical expenses per accident after PIP/MedPay exhaustion, with 92% of these claims triggering subrogation.
Practical Example: Maria, a Florida resident (a PIP state), was injured in a rear-end collision. Her PIP policy covered $10,000 in initial care, and her MedPay (with a $5,000 limit) covered $3,000 more. Her remaining $15,000 in surgery costs were paid by her health insurer. Six months later, her health insurer filed a subrogation claim to recoup the $15,000.
Pro Tip: Save all PIP/MedPay exhaustion notices and health insurance Explanation of Benefits (EOBs) in a cloud folder. This documentation proves your health insurer’s payment was secondary, preventing disputes.

Reimbursement Targets (At-Fault Party’s Insurance, Settlement Proceeds)

Health insurers pursue two primary targets for subrogation:

1. At-Fault Party’s Auto Insurance

Insurers first seek reimbursement directly from the at-fault driver’s liability coverage. This is the most efficient path, as liability policies are legally obligated to cover accident-related damages[20][21].

2. Policyholder’s Settlement Proceeds

If the at-fault party’s insurance is insufficient (e.g., low policy limits) or disputes liability, insurers will claim a portion of your personal injury settlement. This ensures they recoup costs even if the at-fault party can’t fully pay[8][9].
Comparison Table: Subrogation Targets

Target	Typical Timeline	Success Rate (2025)	Policyholder Impact
At-Fault Insurance	3–6 months	85%	Minimal—no direct settlement reduction
Settlement Proceeds	6–12 months	72%	Reduced net settlement (insurer takes repayment)

Key Takeaways:

At-fault insurance is the preferred target for insurers due to faster resolution.
Settlement subrogation may reduce your payout, so negotiate with both your insurer and the at-fault party’s carrier.

Implications for the Policyholder (Prevention of Double Recovery)

Subrogation exists to prevent “double recovery,” where you’d receive payment from both your health insurance and the at-fault party for the same medical bills[8][22]. Without this process, insurers could face billions in fraudulent claims, leading to higher premiums for all policyholders.
Practical Example: After a car accident in Texas (a non-PIP state), James used $20,000 in health insurance after exhausting his $10,000 MedPay. He later settled with the at-fault driver for $50,000. His health insurer subrogated $20,000 from the settlement, leaving him with $30,000—fair compensation for pain and suffering, not duplicate medical costs.
Interactive Element Suggestion: Try our subrogation impact calculator to estimate how much your settlement might be reduced based on health insurance payments.
As recommended by [subrogation management tools like ClaimPro], proactive communication with your health insurer and attorney can minimize settlement delays. Top-performing solutions include automated subrogation tracking software, which alerts you to pending claims in real time.

Example: MedPay and High-Deductible Health Plans (HDHPs)

78% of HDHP enrollees worry about meeting deductibles after accidents (National Association of Insurance Commissioners, 2024)—a concern amplified when auto-related injuries strike. For drivers in the 38 U.S. states without mandatory PIP [2], MedPay can serve as a financial bridge between auto accidents and high-deductible health coverage. Below, we compare scenarios with and without MedPay to illustrate its impact on out-of-pocket costs.

Scenario Without MedPay

Consider Maria, a 42-year-old marketing manager in Colorado (a non-PIP state) with a $7,500 HDHP deductible and no MedPay. While commuting, she’s rear-ended by a distracted driver, requiring emergency care, surgery, and physical therapy totaling $12,000 in medical bills [23].
Since Colorado doesn’t mandate PIP, Maria must cover costs upfront [24]. Her health insurance won’t contribute until she meets her deductible, leaving her responsible for the full $7,500 deductible. After that, her plan covers 80% of remaining costs, adding $900 (20% of $4,500) in coinsurance.
Total out-of-pocket cost without MedPay: $8,400
*Pro Tip: Always ask your health insurer about subrogation terms upfront—they may seek reimbursement from the at-fault driver’s insurance later, but you’ll still owe the deductible in the short term [9] [20].

Now, imagine Maria added $5,000 MedPay to her auto policy (average annual cost: $150–$300, per Insurance Information Institute, 2025). In the same accident, her MedPay activates first, covering $5,000 of the $12,000 medical bills [11].
This reduces her remaining health insurance responsibility to $7,000. With her $7,500 deductible, she only needs to pay $2,000 out-of-pocket to meet the deductible (since MedPay already covered $5,000).
Total out-of-pocket cost with MedPay: $2,400
As recommended by [auto insurance comparison tools], drivers with HDHPs should prioritize MedPay limits equal to 50–75% of their deductible to maximize savings.

Impact on Out-of-Pocket Costs

Comparison Table: MedPay vs. No MedPay for HDHP Enrollees

Cost Category	Without MedPay	With $5,000 MedPay	Difference
Initial medical bills (total)	$12,000	$12,000	$0
Deductible responsibility	$7,500	$2,000	-$5,500
Coinsurance (20% after deductible)	$900	$400	-$500
Total out-of-pocket	$8,400	$2,400	-$6,000

Key Takeaways:

MedPay reduces HDHP deductible exposure by an average of 65% in moderate-to-severe accidents (based on the scenario above).
Subrogation still applies: If Maria later receives a settlement from the at-fault driver, her health insurer may seek reimbursement for costs covered post-deductible [25].
*Pro Tip: Pair MedPay with a Health Savings Account (HSA) to further offset remaining deductibles—HSAs allow tax-free withdrawals for qualified medical expenses.
Try our MedPay Savings Estimator to calculate your potential out-of-pocket reduction based on your deductible and local accident averages.
Top-performing MedPay solutions include options from Allstate, State Farm, and Progressive, with limits ranging from $1,000–$10,000.

FAQ

What is subrogation in auto medical coverage coordination?

The American Association for Justice (2023) defines subrogation as the process where health insurers seek reimbursement for accident-related medical costs after PIP or MedPay benefits are exhausted. Triggers include:

Health insurance payments after PIP/MedPay exhaustion
Settlements from at-fault parties’ liability insurance
Detailed in our Subrogation Process section, this prevents "double recovery" of medical expenses. Results may vary depending on state laws and policy clauses.

How do PIP and health insurance coordinate payment after an auto accident?

According to the Insurance Information Institute (2023), coordination follows a strict hierarchy:

PIP acts as primary payer, covering initial costs up to its limit (e.g., $2,000–$10,000 in no-fault states).
Health insurance activates as secondary payer once PIP is exhausted, often requiring subrogation later.
This process is detailed in our Payment Priority analysis, ensuring minimal out-of-pocket costs for policyholders.

PIP vs. MedPay: How do their coverage scopes differ for accident-related expenses?

Unlike MedPay, which covers only medical expenses (e.g., ER visits, passenger bills), PIP includes non-medical costs like lost wages and rehabilitation, per 2025 auto insurance industry standards. PIP is mandatory in 12 no-fault states, while MedPay is optional nationwide. Professional insurance comparison platforms highlight PIP as “comprehensive primary coverage” versus MedPay’s “supplemental gap filler.”

Steps to file a MedPay claim after exhausting PIP benefits

The Insurance Information Institute recommends these steps:

Obtain PIP exhaustion documentation from your auto insurer.
Submit MedPay claim forms with medical bills and accident reports.
Await reimbursement (typically 2–4 weeks, with no deductibles).
Detailed in our MedPay as Secondary Payer section, this process uses industry-standard coordination tools to streamline payments.
