For businesses and legal professionals, navigating the intersection of state-mandated insurance and federal healthcare law is a high-stakes endeavor. When an employee is injured on the job, the primary responsibility for medical costs typically falls on the employer’s insurance provider. However, if that employee is also eligible for Medicare, the Medicare Secondary Payer (MSP) provisions enter the frame.
Failure to comply with MSP regulations can lead to double-damages, denied claims, and significant delays in settlement approvals. This guide provides a prescriptive roadmap for maintaining compliance and protecting Medicare’s interests throughout the workers’ compensation lifecycle.

Understanding the Landscape: Why Medicare is “Secondary”
The Medicare Secondary Payer Act was established to ensure that the federal government does not pay for medical services that another “primary” payer is responsible for covering [1]. In the context of workers’ compensation, Medicare is always the secondary payer. This means if a workplace injury occurs, the workers’ compensation carrier or self-insured employer must pay for injury-related care before Medicare pays a single dollar.
As detailed in our overview of Why Your Business Needs Workers’ Compensation Insurance, this coverage is the first line of defense. However, the complexity arises when a case settles. Medicare must be assured that the settlement funds will be used for future injury-related medical care so that Medicare doesn’t end up footing the bill later.
Being a secondary payer means Medicare is not responsible for medical costs when another insurance, such as workers’ compensation, has primary liability. The employer’s insurance carrier must pay for all injury-related care before Medicare can be billed for any services.
Medicare must be protected to ensure that federal funds are not used for medical care that should have been covered by a settlement. Failing to account for future injury-related costs can lead to Medicare denying future claims or seeking reimbursement from the settlement parties.
The Core Pillar: Medicare Set-Aside Arrangements (WCMSAs)
The gold standard for MSP compliance in settlements is the Workers’ Compensation Medicare Set-Aside Arrangement (WCMSA). A WCMSA is a financial agreement that allocates a portion of a workers’ compensation settlement to pay for future medical services that would otherwise be covered by Medicare [2].
When do you need a WCMSA?
While Medicare’s interest must always be considered, the Centers for Medicare & Medicaid Services (CMS) has established specific review thresholds for when they will formally review a proposal:
The claimant is currently a Medicare beneficiary: The total settlement amount is greater than $25,000.
The claimant has a “reasonable expectation” of Medicare enrollment within 30 months: The total settlement amount is greater than $250,000 [1].
If your case falls below these thresholds, you must still document how you protected Medicare’s interests, even if you don’t submit the plan for formal CMS review. On platforms like Reddit, legal professionals often discuss the “Non-Submit” strategy, where parties calculate a set-aside but choose not to seek CMS approval to avoid administrative delays; however, this carries an inherent risk if the calculation is later deemed insufficient by the government.
| Claimant Status | Specific Thresholds for CMS Review |
|---|---|
| Current Medicare Beneficiary | Total settlement amount exceeds $25,000 |
| Reasonable Expectation of Medicare (within 30 months) | Total settlement amount exceeds $250,000 |
A WCMSA is recommended when the claimant is a Medicare beneficiary and the settlement exceeds $25,000, or when the claimant is likely to enroll in Medicare within 30 months and the settlement exceeds $250,000. Even below these thresholds, Medicare’s interests must be documented and protected.
While a non-submit strategy avoids administrative delays from CMS review, it carries the risk that Medicare may later determine the set-aside amount was insufficient. If this happens, Medicare may refuse to pay for future injury-related treatments until the entire settlement is exhausted.
Step-by-Step Compliance Process
1. Reporting and Verification
The first step is identifying the claimant’s Medicare status. You must report the case to the Benefits Coordination & Recovery Center (BCRC) early [3]. The BCRC tracks Medicare expenditures made while a claim is pending.
2. Identifying Conditional Payments
If a worker receives treatment and Medicare pays for it before the workers’ compensation claim is settled, these are called conditional payments. Medicare has a legal right to be reimbursed for these payments. Organizations should request a Conditional Payment Letter (CPL) to identify the exact amount owed before finalizing any settlement.
3. Calculating the Future Medical Allocation
To determine the WCMSA amount, you must analyze the claimant’s medical records and pharmacy history (typically the last two years). The calculation must reflect the actual cost of future treatments based on state workers’ compensation fee schedules. It is worth noting that Medicare Secondary Payer Rules for Group Health Plans differ slightly in their coordination, but for workers’ comp, the focus is strictly on the specific injury.
4. Choosing a Funding Structure
WCMSAs can be funded in two ways:
Lump-Sum: A single payment covers all future medical expenses.
Structured Settlement: An initial seed payment followed by annual payments for a set period. This is often more cost-effective for the employer and ensures the claimant doesn’t exhaust funds too quickly [2].
Conditional payments are medical costs Medicare paid for injury-related care while the workers’ compensation claim was still pending. These payments are made on the condition that they will be reimbursed to the federal government once the claim is settled or liability is established.
A structured settlement is often more cost-effective for employers and provides the claimant with an initial seed payment followed by annual funds. This structure ensures that money is available for long-term care and prevents the claimant from exhausting the medical funds prematurely.
The Risk of Non-Compliance: Double Damages
The federal government has “super lien” powers. If a settlement occurs and Medicare’s interests are ignored, the government can sue the primary payer (the insurer or employer) for double damages plus interest [4]. CMS can also deny the claimant future medical coverage for the injury until the entire settlement amount is exhausted on medical care.
Under the Medicare Secondary Payer Act, the federal government has the authority to sue primary payers for double damages plus interest if they fail to reimburse Medicare or ignore its interests. This “super lien” power makes non-compliance a significant financial risk for insurers and employers.
Yes, if a settlement is reached without properly protecting Medicare’s interests, CMS may deny the claimant future medical coverage for that specific injury. The claimant would then be forced to pay for care out of their own pocket until they can prove they spent the equivalent of the settlement on medical bills.
Management and Administration
Once a WCMSA is funded, it must be administered properly.
Self-Administration: The claimant manages the funds but must keep strict records and provide annual attestations to CMS.
Professional Administration: A third-party firm manages the funds, pays bills at appropriate rates, and handles all reporting. Professional administration is highly recommended to ensure the funds are not accidentally spent on non-covered items, which could jeopardize the claimant’s future Medicare benefits.
Self-administration requires the claimant to manage funds, keep receipts, and provide annual reports to CMS, which can be complex. Professional administration involves hiring a third-party firm to manage payments at proper fee schedules and handle all government reporting, ensuring local and federal compliance.
Professional administration protects the claimant’s future Medicare benefits by ensuring funds are only spent on Medicare-covered items at correct pricing. It also relieves the claimant of the administrative burden and provides the government with accurate records of how the settlement funds were used.
Summary of Key Takeaways
Medicare is Always Secondary: In workers’ compensation cases, the employer/carrier must pay first for injury-related care.
Thresholds Matter: CMS review is typical for settlements over $25,000 for current beneficiaries or $250,000 for those likely to join Medicare soon.
Conditional Payments: These must be identified and repaid to the BCRC.
Administration is Critical: Funds in a Set-Aside must be spent only on Medicare-covered items related to the workplace injury.
Action Plan for Employers and Adjusters
- Check Status: Verify the Social Security and Medicare status of every claimant at the start of a claim.
- Monitor Spending: Track medical treatments to anticipate potential WCMSA amounts.
- Request the CPL: Obtain a Conditional Payment Letter at least 60 days before any mediation or settlement discussion.
- Use Professionals: Hire a certified MSP specialist to calculate the WCMSA to ensure it meets CMS “Evidence-Based Medicine” (EBM) standards.
- Finalize Liens: Ensure all conditional payments are paid and a “Final Demand” letter is received from the BCRC before closing the file.
Compliance with the Medicare Secondary Payer Act is not just a regulatory checkbox; it is a financial necessity. By proactively identifying Medicare beneficiaries and following the formal WCMSA process, businesses can close claims with the certainty that they will not face future federal litigation or unexpected “double damage” penalties.
| Compliance Pillar | Key Action or Requirement |
|---|---|
| Primary Responsibility | Employer/Carrier pays before Medicare for injury-related care. |
| Lien Resolution | Identify and repay all conditional payments to the BCRC. |
| Set-Aside (WCMSA) | Allocate funds for future care; seek CMS review if thresholds are met. |
| Administration | Professionally manage funds to protect future Medicare eligibility. |
| Penalty Risk | Non-compliance results in federal lawsuits and double damages. |
The first step is to verify the Social Security and Medicare enrollment status of every claimant at the very beginning of the claim. This allows the employer to anticipate whether CMS review thresholds will be met and to start tracking Medicare’s potential interest early.
Adjusters should request a CPL from the BCRC at least 60 days before any mediation or settlement discussion. This ensures there is enough time to identify, dispute, or verify the exact amount Medicare expects to be reimbursed before final figures are agreed upon.
