MSP Act Compliance: Reporting Requirements and Pharmacy Lien Priority

James Wong — Founder & Pharmacist, LienScripts | March 26, 2026 | 8 min read

The Medicare Secondary Payer Act imposes reporting obligations and creates a statutory lien that takes priority over most other claims at settlement. PI attorneys must understand MSP compliance requirements and how pharmacy liens fit into the priority hierarchy when Medicare beneficiaries are involved.

The Medicare Secondary Payer (MSP) Act, codified at 42 U.S.C. § 1395y(b), establishes that Medicare does not pay for medical expenses when a primary payer is responsible, creates a federal statutory right of recovery against settlements, and imposes reporting obligations on liability insurers and self-insured entities. Pharmacy liens operate alongside MSP obligations because they cover costs Medicare never paid, making them complementary rather than competing claims in the settlement waterfall.

• The MSP Act creates a federal statutory lien on PI settlements for conditional payment reimbursement
• MMSEA Section 111 requires reporting of settlements involving Medicare beneficiaries to CMS within strict timelines
• Medicare's recovery right has federal priority — it is satisfied before most other claims except attorney fees
• Pharmacy liens cover costs outside Medicare's payment system and are not subject to MSP recovery
• LienScripts generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report that documents lien-funded medication costs separately from Medicare-covered expenses

MSP Act: The Federal Priority Framework

The MSP Act establishes Medicare as a secondary payer in situations where another party has primary payment responsibility. In PI cases, the tortfeasor's liability insurer — or the settlement itself — is the primary payer. Medicare's role is to provide interim coverage (conditional payments) until the primary payer resolves the claim.

Once the settlement occurs, Medicare's statutory right of recovery activates. Under 42 U.S.C. § 1395y(b)(2)(B), the United States government may recover conditional payments directly from any entity that received payment from the primary plan — including the plaintiff, the plaintiff's attorney, and the liability insurer.

This federal statutory lien takes priority over state-law liens and most contractual claims. The only deductions typically permitted before satisfying Medicare's claim are attorney fees and litigation costs (the procurement cost offset).

[!KEY] Medicare's recovery right under the MSP Act is a federal statutory obligation — it cannot be negotiated away, settled for zero, or subordinated to other liens. However, it covers only amounts Medicare actually paid. Pharmacy lien costs were never paid by Medicare and are outside the MSP Act's reach.

MMSEA Section 111 Reporting Requirements

The Medicare, Medicaid, and SCHIP Extension Act of 2007 (MMSEA) added Section 111 reporting requirements. These apply to:

Responsible Reporting Entities (RREs): Liability insurers, self-insured entities, no-fault insurers, and workers' compensation carriers must report settlements involving Medicare beneficiaries to CMS.

What must be reported: The settlement amount, claimant's Medicare ID, date of injury, and nature of injury. Reporting is required for all physical trauma settlements involving Medicare beneficiaries, regardless of amount.

Timeline: RREs must report within the quarterly reporting cycle following the settlement date. Penalties for non-compliance can reach $1,000 per day per unreported claim.

Impact on attorneys: While the reporting obligation falls on the insurer or RRE, attorneys must ensure their clients' Medicare status is correctly identified. If the client is a Medicare beneficiary and the insurer fails to report, CMS may pursue recovery directly from the plaintiff or the plaintiff's attorney.

According to James Wong, PharmD, founder of LienScripts, "We flag Medicare-eligible cases in our system and coordinate with the attorney's office to ensure that pharmacy lien documentation clearly separates lien-funded costs from Medicare-covered expenses. When MMSEA reporting triggers CMS's interest in a case, having the MERIT report already prepared accelerates the resolution timeline."

[!TIP] At intake, ask every client whether they have Medicare coverage — Part A, Part B, Part D, or Medicare Advantage. Also screen for clients approaching age 65 or who have applied for SSDI. Missing a Medicare beneficiary triggers compliance problems that surface months later at settlement.

Pharmacy Lien Priority in Medicare Cases

The settlement priority hierarchy when Medicare is involved:

1. Attorney fees and costs — deducted first per retainer agreement
2. Medicare conditional payment reimbursement — federal statutory priority, reduced by procurement cost offset
3. Medicare Set-Aside — if applicable, funded from remaining settlement
4. Pharmacy lien — satisfied from net proceeds after Medicare obligations
5. Other medical liens — state-law provider liens
6. Client net recovery — remaining funds

The pharmacy lien sits below Medicare obligations in the waterfall because Medicare's claim is federal and statutory. However, this does not mean the pharmacy lien is at risk of non-payment. The pharmacy lien covers costs that are separate from Medicare's claim — there is no competition for the same dollars.

Why the priority order works: Medicare recovers what Medicare paid (minus procurement costs). The pharmacy lien recovers what the lien provider advanced. The two amounts, when combined, represent the total past medical expenses from two different funding sources. As long as the settlement is sufficient to cover both plus attorney fees and any MSA, both obligations are satisfied in full.

When Settlement Funds Are Insufficient

In cases where the settlement does not cover all obligations — Medicare conditional payments, MSA, pharmacy lien, and other liens — attorneys face allocation challenges:

Medicare cannot be shortchanged. The MSP Act's federal priority means CMS will pursue recovery regardless of other obligations. Settling for less than Medicare's claim requires a compromise or waiver from CMS, which is difficult to obtain.

Pharmacy liens may need negotiation. If the remaining funds after Medicare obligations and attorney fees are insufficient to satisfy the full pharmacy lien, LienScripts works with attorneys to negotiate the lien amount. LienScripts has the flexibility to reduce lien amounts when the settlement economics require it — a practical advantage over Medicare, which has limited negotiation authority.

Document everything. When requesting a pharmacy lien reduction, provide the full settlement breakdown showing Medicare's claim, the MSA (if applicable), and the remaining funds. Transparency produces better outcomes.

[!KEY] Medicare's statutory priority is absolute — it must be satisfied before other claims. But pharmacy liens and Medicare's conditional payments draw from different expense categories. The priority question only matters when the total settlement is insufficient to cover all obligations. In those cases, the pharmacy lien provider's willingness to negotiate gives attorneys the flexibility that Medicare's statutory framework does not.

MSP Double Damages and the Private Cause of Action

The MSP Act includes a private cause of action with double damages under 42 U.S.C. § 1395y(b)(3)(A). This provision allows the United States — or a private plaintiff — to recover double the amount of conditional payments from any entity that failed to reimburse Medicare as primary payer.

For PI attorneys, this creates a compliance imperative: failing to reimburse Medicare from the settlement can expose both the plaintiff and the attorney to double damages liability. The risk is manageable with proper process:

1. Identify Medicare status at intake
2. Request the conditional payment letter early
3. Challenge unrelated charges on the CPL
4. Apply procurement cost offset
5. Reimburse Medicare from trust funds before disbursement
6. Satisfy the pharmacy lien from remaining net proceeds
7. Document the entire allocation

The MERIT report from LienScripts provides part of this documentation chain — it demonstrates that pharmacy costs were handled through a separate channel and were never Medicare's responsibility.

Coordination Checklist for Medicare PI Cases

• Confirm Medicare enrollment status at intake (Part A, B, D, Advantage)
• Enroll in pharmacy lien to minimize future conditional payments on medications
• Request conditional payment letter from BCRC during case development
• Dispute unrelated charges on the CPL with medical records
• Determine whether MSA is required (beneficiary status + settlement amount)
• Calculate settlement waterfall: fees, Medicare repayment, MSA, pharmacy lien, client net
• Request MERIT report from LienScripts for lien documentation
• Reimburse Medicare within 60 days of final demand
• Satisfy pharmacy lien from remaining net proceeds
• Retain allocation documentation in case file
