Every California PI settlement involving a Medicare beneficiary carries a federal claim attached to it, and the United States is not a creditor that signs releases. The Medicare Secondary Payer statute sits behind every conditional payment letter the Benefits Coordination & Recovery Center issues, and the recovery contractor will collect from the client, counsel, the carrier, or the responsible party — whichever target moves first.
Plaintiff lawyers who treat MSP recovery as an afterthought lose money on the procurement cost reduction, blow the 60-day post-demand interest tolling window, and occasionally end up personally on the hook under 42 U.S.C. § 1395y(b)(2)(B)(iii). The case law since Bradley v. Sebelius has clarified some recovery questions and complicated others. What follows is the working framework for handling conditional payments in a 2026 California settlement.
How the MSP statute allocates the loss
The MSP statute makes Medicare a secondary payer when payment "has been made or can reasonably be expected to be made" by a workers' comp plan, automobile or liability insurer, or no-fault insurer. 42 U.S.C. § 1395y(b)(2)(A). When Medicare advances payment because the liability source has not yet paid, those payments are "conditional" — recoverable once the primary plan's responsibility is demonstrated by a judgment, settlement, award, or other payment. § 1395y(b)(2)(B)(ii).
The recovery teeth are in subsection (B)(iii): the United States may sue any entity that received payment from a primary plan, including the beneficiary, the attorney, and the carrier. Double damages are available. That is why the proof-of-representation and consent-to-release filings matter at intake — they determine who the recovery contractor sees on the case and where the demand letter goes.
Reading the conditional payment letter
Within roughly 65 days of CMS receiving notice that a beneficiary has a pending liability claim — via Section 111 reporting by the carrier or self-reporting by counsel — the BCRC issues a Rights and Responsibilities letter and opens a case in the Medicare Secondary Payer Recovery Portal. The Conditional Payment Letter (CPL) lists every claim line the contractor believes is related to the alleged injury.
Two things to do on receipt. First, pull the Payment Summary Form and cross-reference each ICD-10 diagnosis code against the client's actual medical history. CMS routinely captures unrelated treatment — diabetes follow-ups, pre-existing cardiac care, dermatology — when the date of service happens to fall after the injury date. Each unrelated line is a candidate for removal through the portal's dispute process before final demand. Second, confirm the date of incident on file. The DOI controls the inclusion window, and a mis-coded DOI can inflate the ledger by years of unrelated claims.
A successful pre-demand dispute eliminates the cost of fighting the same claim on appeal under the much tighter post-demand timeline. The portal accepts the dispute documentation electronically, and the contractor will adjust the CPL before the case ripens to final demand.
Post-Bradley: allocation, procurement, and the recovery math
Bradley v. Sebelius, 621 F.3d 1330 (11th Cir. 2010), pushed back on CMS's prior position that it could ignore state-court allocations of settlement proceeds among heirs and recover from the gross. The Eleventh Circuit held the allocation order binding on the agency. CMS has not formally adopted Bradley nationally, but the case is regularly cited in administrative appeals where counsel obtained a probate or court allocation order before final demand. In California liability cases with multiple claimants, a recorded allocation is the document that gives an appeal traction.
The Ninth Circuit in Haro v. Sebelius, 747 F.3d 1099 (9th Cir. 2014), addressed a different question — whether CMS could demand payment before the appeal exhausted — and ruled that the agency had to follow its own waiver and appeal procedures before treating the debt as collectible. Haro matters in California because it provides the procedural backstop for a beneficiary who disputes relatedness while the contractor presses collection.
Procurement cost reduction is the regulation that puts real money back in the client's pocket. Under 42 C.F.R. § 411.37, when the beneficiary's procurement costs — attorney's fees and litigation expenses — are deducted from the recovery, the conditional payment amount is reduced in proportion. The formula:
Reduction ratio = procurement costs ÷ gross settlement
Net Medicare recovery = conditional payments × (1 − reduction ratio)
On a $300,000 settlement with a $120,000 contingent fee plus $15,000 in costs, the procurement ratio is 0.45. A $40,000 conditional payment ledger drops to $22,000 under § 411.37(c). Counsel who skip the procurement calculation hand the program an $18,000 windfall that belonged to the client.
Final demand, the 60-day rule, and waiver
After settlement, counsel submits the settlement information through the portal — gross amount, attorney's fees, costs, and date of settlement. Within roughly 30 days, the contractor issues a Final Demand Letter setting the actual amount owed. Three response paths exist.
The 60-day rule. Payment within 60 days of the demand date stops interest from accruing. 42 C.F.R. § 411.24(m). Interest runs at the current Treasury rate from day 61. If the file is in dispute, send a partial payment with a written reservation of rights and continue the appeal — interest tolls on the paid portion while the disputed balance works through redetermination.
Appeal. Five levels are available: redetermination by the contractor, reconsideration by the Qualified Independent Contractor, ALJ hearing, Medicare Appeals Council, and federal district court. 42 C.F.R. Part 405, Subpart I. The redetermination request is due within 120 days of demand, but file within 30 to preserve options. The contractor will trim relatedness disputes at redetermination when the medical record is clean — the majority of cases never reach the QIC.
Waiver and compromise. Section 1870(c) of the Social Security Act allows waiver where the beneficiary is "without fault" and recovery would defeat the purpose of the Act or be against equity and good conscience. This is the path for catastrophically injured clients with low net recoveries. Compromise under § 1870(b) is discretionary and rarely granted in liability cases above the mid five-figures of net-to-client.
The settlement workflow that survives CMS audit
A reproducible PI settlement workflow with a Medicare beneficiary looks like this.
Pre-suit. Confirm Part A and B entitlement dates at intake. Section 111 reporting begins the moment a carrier has notice of the claim — the conditional payment process starts whether or not counsel triggers it.
Pre-mediation. Pull the CPL and dispute every unrelated claim line through the portal. Get the ledger to its defensible floor before any number drives the mediation conversation. Demands premised on the unaudited CPL hand the defense an argument that the client's special damages are inflated by unrelated care.
Settlement. Allocate on the record where the facts support it — pain and suffering, future medicals, loss of consortium. CMS is not bound by every allocation, but allocations supported by judicial findings carry weight on appeal under the Bradley reasoning. The same allocation discipline that drives California Civil Code §§ 3045.1–3045.6 hospital lien practice applies here: allocate, document, force the lienholder to overcome the record.
Funding. Hold settlement proceeds in trust until the final demand letter lands. Disbursing before final demand — even with a CPL number in hand — exposes counsel to § 1395y(b)(2)(B)(iii) liability. Document the trust hold in the closing statement to the client.
Post-demand. Pay, appeal, or both. Send payment to the BCRC payment address — not the contractor's correspondence address, which bounces payments back.
When Medicare stacks against Medi-Cal, ERISA plans, and hospital liens, the order of operations matters. See the related practice notes on Medi-Cal lien reduction under Ahlborn and ERISA reimbursement in California PI settlements. Medicare's procurement reduction is automatic by formula; Medi-Cal and ERISA reductions are negotiated. Run all three before final disbursement and a single client check.
Errors that cost real money
Treating the CPL as final. The conditional payment letter is a snapshot subject to update. The contractor can — and routinely does — add claims between CPL and final demand if new lines post during the lag. Counsel who treat the early CPL as the ceiling get surprised by a higher demand number after settlement.
Missing the Medicare Advantage problem. Medicare Advantage organizations (Part C) have asserted a private right of action under In re Avandia, 685 F.3d 353 (3d Cir. 2012), and other circuits have followed similar reasoning. MAOs are not in the BCRC system. Counsel must separately confirm whether the client was enrolled in a Part C plan during the treatment period and request a recovery letter directly from that plan. A clean BCRC file does not foreclose a six-figure MAO claim that surfaces six months after disbursement.
Forgetting the future. An MSA is not formally required in liability settlements — CMS policy memos on liability MSAs remain non-binding — but a settlement that ignores future injury-related Medicare exposure can produce a future-medicals problem under § 1395y(b)(2). For high-value cases with continuing care, document an allocation showing whether future medicals were funded or excluded, and where funded, how the client will administer the set-aside.
Medicare's recovery position is procedural before it is substantive. Counsel who run the portal disciplined, dispute the CPL before mediation, calculate the § 411.37 reduction precisely, and hold trust funds until final demand will close MSP files at numbers the contractor accepts on the first pass. The settlements that go sideways are the ones where the conditional payment number was treated as background noise until the day of distribution.
