Medicare Secondary Payer (MSP) compliance means following federal rules that determine when another payer must cover medical expenses before Medicare. It also means making sure Medicare is repaid when it covers care that another payer was responsible for.

In workers’ compensation, liability, and no-fault claims involving Medicare beneficiaries, MSP compliance generally involves reporting claims to Medicare, resolving payments Medicare made on another payer’s behalf, and planning for future medical expenses when a claim settles.

These requirements are outlined in federal law and regulations, including Medicare Secondary Payer rules.

Why Does MSP Compliance Matter?

MSP compliance helps ensure the correct payer covers medical expenses and that Medicare does not pay for care another payer is responsible for.

For claims professionals, missing these requirements can lead to repayment demands, civil money penalties for late reporting, or Medicare denying coverage for injury-related care after a settlement. Addressing MSP requirements early can help prevent delays and complications during settlement.

What Does MSP Compliance Involve?

MSP compliance centers on three main areas: Section 111 reporting, conditional payments, and Medicare Set-Aside Arrangements (MSAs).

Section 111 Reporting

Section 111 reporting requires certain insurers and other responsible entities to report claims involving Medicare beneficiaries to the Centers for Medicare & Medicaid Services (CMS). This helps Medicare determine when another payer is responsible for medical expenses.

The reporting requirement applies to workers’ compensation, liability, and no-fault claims. The responsible reporting entity (RRE) must ensure the required information is submitted accurately and on time.

CMS can impose civil money penalties for late reporting. Enforcement began in October 2025, making timely reporting an important part of MSP compliance.

Conditional Payments

Conditional payments are payments Medicare makes for medical care when another payer may be responsible but has not paid yet.

If a workers’ compensation or liability claim later settles, Medicare may seek repayment for covered expenses it paid related to the claim. Claims professionals should identify and resolve these payments as part of the settlement process to help avoid outstanding repayment obligations.

Medicare Set-Aside (MSA)

A Medicare Set-Aside Arrangement (MSA) reserves part of a workers’ compensation settlement to cover future medical expenses related to the injury that Medicare would otherwise pay for.

An MSA helps protect Medicare’s interests by accounting for future medical care before Medicare begins covering those expenses. Not every claim involving a Medicare beneficiary requires an MSA, and CMS does not require every arrangement to be submitted for review.

CMS has review thresholds based on the claimant’s Medicare status and the settlement amount. However, those thresholds do not eliminate the need to consider Medicare’s interests in other cases.

MSA information must also be included in Section 111 reporting for applicable workers’ compensation settlements, whether or not the arrangement was submitted to CMS for review.

How Can Claims Professionals Support MSP Compliance?

The best way to support MSP compliance is to address Medicare requirements early in the claim rather than waiting until settlement. A few practical steps can help:

  • Confirm Medicare status early: Identify whether the claimant is a Medicare beneficiary or may qualify for Medicare soon.
  • Keep reporting on track: Confirm the responsible reporting entity is submitting required information accurately and on time.
  • Address conditional payments before settlement: Identify potential repayment obligations and include them in settlement planning.
  • Consider future medical needs: Evaluate whether an MSA or another approach to future medical expenses is appropriate for the claim.
  • Document key decisions: Keep records of reporting, repayment, and future medical planning to support the handling of the claim.

The specific requirements depend on the claim and its circumstances. Staying current with CMS guidance and addressing MSP obligations throughout the claims process can help reduce compliance risks and prevent avoidable settlement issues.
