Medicare Advantage Plans and Pharmacy Lien Coordination in Personal Injury Cases

Amar Lunagaria — Chief Pharmacist, LienScripts | March 29, 2026 | 8 min read

Medicare Advantage (Part C) plans handle subrogation differently than traditional Medicare — each plan has its own recovery process, formulary restrictions, and lien assertion procedures. PI attorneys must understand how Medicare Advantage subrogation behavior interacts with pharmacy liens to avoid compliance pitfalls and protect client recovery.

Medicare Advantage plans assert private-plan subrogation rights that differ from traditional Medicare's MSP recovery process, and their pharmacy formulary restrictions frequently leave accident-related specialty medications uncovered — making pharmacy lien coordination essential for PI attorneys handling cases involving Medicare Advantage beneficiaries.

• Medicare Advantage (Part C) plans are private insurance plans that contract with CMS to provide Medicare benefits, and each plan has its own subrogation and recovery procedures
• Medicare Advantage pharmacy formularies vary by plan and often exclude specialty medications commonly prescribed after serious accidents
• LienScripts fills Medicare Advantage formulary gaps by dispensing non-covered medications on lien, while preserving the Medicare Set-Aside compliance framework
• The Medicare Secondary Payer (MSP) Act creates conditional payment recovery rights that apply differently to Medicare Advantage plans than to traditional Medicare
• According to Amar Lunagaria, PharmD, LienScripts' Chief Pharmacist, "Medicare Advantage formularies are often more restrictive than traditional Medicare Part D — in PI cases, the specialty medications a treating physician prescribes may require step therapy or prior authorization that takes weeks, leaving the patient without access unless a pharmacy lien is in place"

Medicare Advantage in the PI Context

Medicare Advantage plans (Medicare Part C) are private health insurance plans approved by the Centers for Medicare & Medicaid Services (CMS) that provide Medicare-covered benefits. Over 30 million Americans — more than half of all Medicare beneficiaries — are enrolled in Medicare Advantage plans as of 2026.

For PI attorneys, Medicare Advantage creates a distinct set of challenges compared to traditional Medicare. The plan is a private insurer, but it operates under federal Medicare rules. This hybrid status affects subrogation rights, conditional payment recovery, and pharmacy coverage in ways that differ from both traditional Medicare and standard private insurance.

[!KEY] Medicare Advantage plans are private insurers operating under federal Medicare rules. Their subrogation behavior combines elements of private insurance recovery and Medicare Secondary Payer Act compliance — attorneys must navigate both frameworks simultaneously when coordinating with pharmacy liens.

Medicare Advantage Pharmacy Formulary Restrictions

Each Medicare Advantage plan maintains its own pharmacy formulary, subject to CMS minimum coverage requirements. While CMS requires all Part D formularies to cover certain drug categories, the specific medications on each plan's formulary, the tier placement, and the utilization management requirements (prior authorization, step therapy, quantity limits) vary significantly.

Common formulary gaps in PI cases:

• Extended-release pain medications. Many Medicare Advantage formularies favor generics and may not cover newer extended-release formulations commonly prescribed after accidents.
• Muscle relaxants. Some plans restrict coverage of certain muscle relaxants or require step therapy (trying a cheaper option first before approving the prescribed medication).
• Specialty topicals. Prescription pain creams and anti-inflammatory topicals may not be covered or may require prior authorization.
• Compound medications. Medicare Advantage plans generally exclude compound medications, which are frequently prescribed in PI pain management.
• Mental health medications. Newer anti-anxiety and sleep medications prescribed for post-accident PTSD or anxiety may face formulary restrictions.

When the treating physician prescribes a medication that is not on the Medicare Advantage formulary — or that requires prior authorization the plan has not yet approved — the patient faces a coverage gap. The pharmacy lien fills this gap.

The Medicare Secondary Payer Act and Medicare Advantage

The Medicare Secondary Payer (MSP) Act (42 U.S.C. 1395y) establishes that Medicare is the secondary payer when a primary plan (such as liability insurance) is responsible for medical expenses. This framework applies to both traditional Medicare and Medicare Advantage plans, but the recovery mechanisms differ.

Traditional Medicare conditional payments. When traditional Medicare pays for accident-related care, the Centers for Medicare & Medicaid Services (through the Benefits Coordination & Recovery Center, BCRC) asserts a conditional payment recovery right against the liability settlement.

Medicare Advantage conditional payments. When a Medicare Advantage plan pays for accident-related care, the plan itself — not CMS — asserts the recovery right. Each Medicare Advantage plan has its own recovery department, procedures, and negotiation practices.

This distinction matters because attorneys cannot use the BCRC portal to identify and negotiate Medicare Advantage conditional payments. Instead, they must contact each Medicare Advantage plan directly to obtain conditional payment information and negotiate recovery.

[!KEY] Medicare Advantage conditional payment recovery is handled by the plan itself, not by CMS or the BCRC. Contact the Medicare Advantage plan's recovery department directly to obtain conditional payment amounts and negotiate reductions. Do not rely on the BCRC portal for Medicare Advantage cases.

Pharmacy Lien Coordination with Medicare Advantage

The pharmacy lien coordination strategy for Medicare Advantage cases follows the same principle as other insurance coordination: use available coverage first, then activate the lien for gaps.

Step 1: Identify the Medicare Advantage plan and formulary. At intake, confirm the client's specific Medicare Advantage plan and request the formulary. Identify which prescribed medications are covered and which are excluded, restricted, or subject to prior authorization.

Step 2: Route covered medications through the plan. For medications on the formulary, the client fills prescriptions through the Medicare Advantage pharmacy benefit, paying applicable copays.

Step 3: Activate the pharmacy lien for non-covered medications. When the treating physician prescribes a medication that the Medicare Advantage plan does not cover — or covers only with prohibitive prior authorization delays — the pharmacy lien provides immediate access.

Step 4: Track both channels for settlement accounting. At settlement, the Medicare Advantage plan's conditional payment recovery and the pharmacy lien payoff are separate obligations.

LienScripts generates a MERIT (Medication Evaluation & Rationale for Injury Treatment) report for every case, providing pharmacist-signed documentation for demand packages. The MERIT report distinguishes between plan-covered and lien-funded medications, supporting both the damages calculation and the MSP compliance framework.

[!TIP] Request the Medicare Advantage plan's formulary at intake and cross-reference it against the treating physician's prescribed medications. Any medication not on the formulary — or requiring prior authorization that will cause delays — should be flagged for immediate pharmacy lien coverage.

Medicare Set-Aside Considerations

In PI cases involving Medicare beneficiaries, Medicare Set-Aside (MSA) obligations may apply. An MSA is an allocation from the settlement to fund future Medicare-covered medical expenses related to the injury, preventing Medicare (or the Medicare Advantage plan) from paying for injury-related care after settlement.

Pharmacy lien costs — because they represent medications already dispensed and not future costs — are not part of the MSA allocation. They are past medical expenses resolved at settlement. However, if the client will need ongoing prescriptions after settlement, those future costs may need to be addressed in the MSA.

How the pharmacy lien relates to MSA:

• Pharmacy lien payoff = past medical expense, satisfied at settlement
• Future prescription costs = potential MSA component, allocated from settlement proceeds
• The pharmacy lien does not increase MSA exposure; it addresses a different category of expense

[!KEY] Pharmacy lien costs are past medical expenses, not future costs. They do not increase the Medicare Set-Aside allocation. The MSA addresses future Medicare-covered injury-related expenses. The pharmacy lien addresses medications already dispensed on credit during the treatment period.

Common Pitfalls in Medicare Advantage PI Cases

Treating Medicare Advantage like traditional Medicare. The recovery procedures, contacts, and negotiation dynamics differ. Do not assume the BCRC process applies to Medicare Advantage conditional payments.

Ignoring formulary restrictions. Medicare Advantage formularies are often more restrictive than attorneys expect. Assuming all prescribed medications are covered leads to prescription access gaps.

Failing to activate the pharmacy lien early. Medicare Advantage prior authorization processes can take weeks. Patients should not wait for plan approval when they need medication now.

Confusing MSA with pharmacy lien payoff. These address different categories of expense. Past lien costs do not inflate the MSA; future prescription needs may.

Practical Steps for Attorneys

1. At intake: Confirm Medicare Advantage enrollment and identify the specific plan. Request the plan's formulary.
2. Cross-reference formulary: Compare prescribed medications against the plan formulary. Flag non-covered and prior-auth-required medications.
3. Enroll in LienScripts: Register the patient so lien coverage is available for non-formulary medications immediately.
4. Contact the plan's recovery department: Identify the conditional payment recovery contact for the Medicare Advantage plan. Do not use the BCRC portal.
5. Track both channels: Monitor plan-covered and lien-funded prescriptions separately for settlement accounting.
6. Address MSA if applicable: Separate past pharmacy lien costs from future prescription needs in the MSA analysis.
7. At settlement: Negotiate the Medicare Advantage plan's conditional payment recovery and the pharmacy lien payoff as independent obligations.

Key Takeaway

Medicare Advantage plans create unique pharmacy lien coordination challenges because each plan has its own formulary, subrogation process, and recovery procedures. PI attorneys must identify formulary gaps early, activate the pharmacy lien for non-covered medications, and navigate the Medicare Advantage conditional payment recovery process separately from the CMS/BCRC framework that applies to traditional Medicare. The pharmacy lien fills coverage gaps without increasing Medicare Set-Aside exposure.
