Coordinating Liability, No-Fault, and Workers’ Compensation with Medicare

Medicare operates as a secondary payer when medical expenses result from accidents or injuries covered by liability insurance, no-fault insurance, or workers’ compensation. Under the Medicare Secondary Payer (MSP) Act, Medicare is prohibited from making payments when another "primary" insurer is responsible, ensuring that federal funds are preserved while private insurers fulfill their contractual and legal obligations.

The intersection of Medicare benefits with personal injury settlements, workplace accidents, and no-fault auto insurance is governed by a complex set of federal statutes and administrative regulations. As of 2026, the Centers for Medicare & Medicaid Services (CMS) maintains strict oversight of how these primary payers interact with the Medicare program. For beneficiaries, attorneys, and insurance carriers, understanding these interactions is vital to avoid significant penalties, loss of benefits, or legal complications during the settlement process.

The Medicare Secondary Payer (MSP) Framework

The foundation of all interactions between Medicare and other insurance types is the Medicare Secondary Payer (MSP) Act, found at 42 U.S.C. § 1395y(b). Historically, Medicare was the primary payer for almost all medical services for its beneficiaries. However, to ensure the long-term sustainability of the program, Congress shifted Medicare to a "secondary" status in cases where other coverage exists.

Under MSP rules, a "primary plan" is defined as any of the following:

• Workers’ Compensation (laws or plans of the United States or a State).
• No-Fault Insurance (including personal injury protection or medical payments coverage).
• Liability Insurance (including self-insurance).

When a Medicare beneficiary is injured, the primary plan is responsible for paying for the medical care related to that injury. Medicare only pays if the primary plan does not pay promptly (usually within 120 days) or if the primary plan’s benefits are exhausted. When Medicare does pay in these situations, the payment is considered "conditional," meaning it must be reimbursed once a settlement, judgment, or award is reached.

Workers’ Compensation and Medicare Coordination

Workers’ compensation is a form of insurance providing wage replacement and medical benefits to employees injured in the course of employment. Because workers' compensation is a "no-fault" system in many jurisdictions, the insurance carrier is the primary payer for all injury-related care.

Workers’ Compensation Medicare Set-Asides (WCMSAs)

One of the most critical components of a workers' compensation settlement is the Workers’ Compensation Medicare Set-Aside (WCMSA). A WCMSA is a financial agreement that allocates a portion of a workers' compensation settlement to pay for future medical services that are related to the work injury and would otherwise be covered by Medicare.

CMS provides a voluntary review process for WCMSAs to ensure that Medicare’s interests are protected. In 2026, the review thresholds remain a primary guide for practitioners:

1. Current Beneficiaries: If the claimant is currently enrolled in Medicare and the total settlement amount is greater than $25,000.
2. Reasonable Expectation of Enrollment: If the claimant is not yet on Medicare but has a "reasonable expectation" of enrollment within 30 months (e.g., they have applied for Social Security Disability Insurance or are 62.5 years old) and the total settlement amount is greater than $250,000.

Protecting Medicare’s Interests

Even if a settlement does not meet the CMS review thresholds, the parties are still legally obligated to protect Medicare’s interests. This means that if a settlement closes the "medical" portion of a claim, the parties must ensure that Medicare does not end up paying for bills that the workers' compensation carrier should have covered. Failure to do so can result in Medicare refusing to pay for any future injury-related treatment until the entire settlement amount is exhausted.

Liability Settlements and Medicare Obligations

Liability insurance (including homeowners, commercial, and auto liability) differs from workers' compensation because it is often based on negligence. However, for MSP purposes, liability insurance is still a primary payer.

Liability Medicare Set-Asides (LMSAs)

Unlike the formalized process for workers' compensation, CMS has not established a formal, mandatory review process for Liability Medicare Set-Asides (LMSAs). However, the legal obligation to protect Medicare’s future interests exists under the same MSP statute.

In a liability settlement, if the medical expenses are expected to continue into the future, the parties must consider whether a portion of the settlement should be set aside. CMS has issued various memos over the years indicating that they expect their interests to be protected, but they often defer to the clinical judgment of treating physicians to determine if future care is necessary.

Conditional Payment Reimbursement

In liability cases, Medicare often pays for medical care while the legal case is pending. These are conditional payments. Once the case settles, Medicare has a priority right of recovery. The Benefits Coordination & Recovery Center (BCRC) is the entity responsible for identifying and recovering these payments. The attorney or the beneficiary must notify the BCRC when a claim is filed so that a "Conditional Payment Letter" (CPL) can be issued, detailing the amount Medicare expects to be paid back from the settlement proceeds.

No-Fault Insurance and Personal Injury Protection (PIP)

No-fault insurance, often referred to as Personal Injury Protection (PIP) or Medical Payments (Med-Pay), is common in many states' automobile insurance laws. In these states, your own insurance company pays for your medical bills regardless of who caused the accident.

Primary vs. Secondary Status

In the hierarchy of payment, No-Fault insurance is almost always primary to Medicare. If a Medicare beneficiary is in a car accident in a no-fault state:

1. The No-Fault/PIP carrier pays medical bills up to the policy limit (e.g., $10,000 or $50,000).
2. Once the No-Fault limits are exhausted, Medicare becomes the primary payer for remaining covered services.

Medicare will generally not pay any bills until the primary insurer has issued a "formal exhaustion of benefits" notice. If Medicare does pay before exhaustion, it will seek recovery from the No-Fault carrier or the beneficiary. It is crucial for healthcare providers to bill the No-Fault carrier first to avoid claim denials from Medicare.

Section 111 Reporting Requirements

To enforce the MSP Act, the Medicare, Medicaid, and SCHIP Extension Act of 2007 (MMSEA) introduced "Section 111 Reporting." This requires primary payers (insurers and self-insured entities) to report settlements, judgments, and awards involving Medicare beneficiaries to CMS.

The reporting process involves:

• Querying: Insurers must query the CMS system to determine if a claimant is a Medicare beneficiary.
• Reporting: If the claimant is a beneficiary, the insurer must report the Total Payment Obligation to the Claimant (TPOC) and any ongoing responsibility for medicals (ORM).

This system ensures that CMS is aware of settlements in real-time, allowing them to flag the beneficiary's file and prevent Medicare from paying for injury-related care that was already compensated by a primary payer. In 2026, the penalties for non-compliance with Section 111 reporting are strictly enforced, with potential civil money penalties for failing to report timely or accurately.

Common Pitfalls and Troubleshooting

Navigating the intersection of these insurance types and Medicare requires avoiding several common mistakes that can lead to financial loss.

1. Failing to Identify Medicare Eligibility

The most common mistake is failing to realize a claimant is on Medicare or will be soon. This includes individuals on Social Security Disability Insurance (SSDI), who become eligible for Medicare after a 24-month waiting period. Always query the claimant's status early in the process.

2. Ignoring the "Conditional Payment" Letter

A Conditional Payment Letter (CPL) is not a final bill, but it must be addressed. Attorneys should review the CPL to ensure that the medical codes listed are actually related to the accident. If Medicare includes treatment for an unrelated chronic condition (like diabetes or heart disease) in an auto accident claim, those charges must be contested through the formal CMS appeals process.

3. Underestimating the "Future Interests" Obligation

Many parties believe that if they don't meet the WCMSA review thresholds, they don't need to worry about Medicare. This is a misconception. Even without a formal review, Medicare can deny future benefits if they believe a settlement was "shifted" to Medicare. Maintaining a clear record of how medical expenses were calculated in a settlement is essential.

4. Delayed Reporting

Under Section 111, insurers have specific windows to report settlements. Delays can lead to the BCRC initiating recovery actions against the beneficiary directly, which can result in the loss of Social Security checks or other offsets until the debt is satisfied.

Frequently Asked Questions

Does Medicare pay if I have No-Fault insurance?

Medicare is the secondary payer to No-Fault insurance. Your No-Fault or PIP coverage must pay for your medical bills related to the accident first. Medicare will only step in once your No-Fault policy limits have been completely exhausted. You must provide Medicare with a "Ledger of Exhaustion" from your insurance company to prove that no more primary funds are available.

What is a "Conditional Payment" in a liability case?

A conditional payment is a payment Medicare makes for medical services where another party may be responsible. It is "conditional" because it is made on the condition that Medicare will be reimbursed if the beneficiary receives a settlement or judgment from a liability insurer. Medicare has a "super lien" on these funds, meaning their right to recovery is prioritized over most other creditors.

Do I need a Medicare Set-Aside (MSA) for a liability settlement?

While there is no federal statute explicitly mandating the "MSA" format for liability cases as there is for workers' compensation, the MSP Act still applies. You must "protect Medicare's interests." If your settlement includes money for future medical care that Medicare would otherwise cover, you should consult with a specialist to determine if an LMSA is the best way to document that those funds are being used appropriately.

Can Medicare take my entire settlement?

Federal regulations generally limit Medicare’s recovery to no more than 50% of the beneficiary’s net settlement (after attorney fees and costs are deducted) in certain liability cases. However, specific rules apply, and you may need to request a "hardship waiver" or a "compromise" if the Medicare lien is exceptionally high relative to the settlement amount.

How does the 2026 threshold for Section 111 reporting affect me?

The $750 threshold for reporting physical trauma-based liability settlements remains a key figure in 2026. If your total settlement is $750 or less, the insurer generally does not have to report it to CMS, and Medicare typically does not pursue recovery for conditional payments on these very small claims, provided there is no ongoing responsibility for medicals.

Practical Recommendations for 2026

To successfully manage a claim involving liability, no-fault, workers' compensation, and Medicare, follow these steps:

• Early Verification: Verify the Medicare status of the injured party at the start of the claim. Use the Social Security Administration's verification tools or the CMS Section 111 query process.
• Maintain Records: Keep a detailed log of all medical treatments and separate accident-related care from general health maintenance. This is crucial when disputing unrelated charges on a CPL.
• Notify the BCRC/CRC: As soon as a claim is established, notify the appropriate recovery contractor. For workers' compensation and no-fault claims where there is "Ongoing Responsibility for Medicals" (ORM), the Commercial Reparations Center (CRC) usually handles the recovery. For liability settlements, it is usually the Benefits Coordination & Recovery Center (BCRC).
• Seek Specialized Advice: For settlements involving significant future medical needs, engage a Medicare Secondary Payer specialist to draft MSA allocations. This protects the beneficiary's future eligibility and shields the attorney and insurer from potential litigation.
