Post-Settlement Release Cuts Off Medicare Secondary Payer “Responsibility” for Future Medicals (and Defeats FCA Theories Premised on Primary-Payer Status)

1. Introduction

This appeal arose from a familiar Medicare Secondary Payer (“MSP”) flashpoint: how a lump-sum tort settlement affects responsibility for future medical expenses and the downstream consequences for Medicare reimbursement and fraud theories.

Parties. William and Penelope Stillwell (plaintiffs in the underlying tort case; Penelope later sued individually and as personal representative of William’s estate) pursued claims against two insurers—State Farm Fire & Casualty Company and Motorists Mutual Insurance Company—who insured the tort defendants in an Indiana slip-and-fall case.

Background. The Stillwells settled the Indiana tort action for $200,000. Medicare was reimbursed for pre-settlement conditional payments (about $19,672.99). The dispute concerned post-settlement accident-related care: Penelope contended the insurers remained responsible to reimburse Medicare for those later expenses despite the settlement’s release language and the Indiana court order enforcing that release.

Key issues on appeal.

• Whether the insurers “have or had a responsibility” to pay for William’s post-settlement accident-related medical expenses, as required to invoke the MSP private cause of action.
• Whether the same asserted responsibility could support eight False Claims Act (“FCA”) counts (false claims/false statements/reverse false claims/conspiracy) premised on the idea that providers should have billed the insurers rather than Medicare.
• (Concurring opinion) Whether full faith and credit and Indiana collateral estoppel independently barred the federal suit because Indiana courts enforced a settlement releasing the insurers from all claims (including future-medicals-related theories).

2. Summary of the Opinion

The Eleventh Circuit affirmed dismissal under Rule 12(b)(6). The court held that Penelope could not satisfy the MSP statutory prerequisite—demonstrating that a “primary plan” had responsibility to pay for the medical expenses at issue—because the Indiana-enforced settlement expressly placed responsibility for “any existing or future medical lien” and related matters on the Stillwells, not on the insurers. The insurers therefore had no duty to reimburse Medicare for post-settlement expenses.

Because every FCA count depended on the same premise (that the insurers remained the primary payers for post-settlement expenses), those claims failed as well: providers’ bills to Medicare were not “false,” and the insurers did not conceal an obligation they did not have.

Judge Tjoflat concurred, emphasizing a distinct threshold ground: under 28 U.S.C. § 1738, the Indiana enforcement judgment (affirmed on appeal) was entitled to full faith and credit, and Indiana collateral estoppel barred relitigation of whether the settlement released the insurers from all claims, including the federal theories asserted.

3. Analysis

A. Precedents Cited (and How They Shaped the Result)

1) MSP framework and the “responsibility” prerequisite

• United States v. Baxter Int'l, Inc., 345 F.3d 866 (11th Cir. 2003): Cited for the MSP’s purpose as a cost-shifting collection of provisions. It provides the interpretive backdrop: MSP is designed to make Medicare secondary where other payment sources are responsible.
• MSP Recovery Claims, Series LLC v. ACE Am. Ins. Co., 974 F.3d 1305 (11th Cir. 2020) and MSP Recovery Claims, Series LLC v. Metro. Gen. Ins. Co., 40 F.4th 1295 (11th Cir. 2022) (quoting MSP Recovery, LLC v. Allstate Ins. Co., 835 F.3d 1351 (11th Cir. 2016)): These decisions supplied the controlling articulation: Medicare pays conditionally only when the primary plan cannot “promptly” pay, and a private MSP plaintiff must first show the defendant primary plan “has or had a responsibility” to pay the relevant expenses.
• Glover v. Liett Grp., Inc., 459 F.3d 1304 (11th Cir. 2006): Central to the court’s analysis. It characterizes the “responsibility” showing as a condition precedent to the obligation to reimburse Medicare and recognizes judgments/settlements as the usual means of demonstrating responsibility—particularly after a tort plaintiff obtains a settlement or favorable judgment.
• Humana Med. Plan, Inc. v. W. Heritage Ins. Co., 832 F.3d 1229 (11th Cir. 2016): Used to reject Penelope’s attempt to extend pre-settlement reimbursement cases to post-settlement future medical expenses. Humana stands for the proposition that a liability insurer’s reimbursement duty can persist even after it pays a lump-sum settlement—but in that setting, it is reimbursement for pre-settlement expenses that Medicare (or a Medicare Advantage plan) already conditionally paid.
• Hadden v. United States, 661 F.3d 298 (6th Cir. 2011): Cited (and distinguished) similarly to Humana, reinforcing that settlement proceeds can demonstrate responsibility for conditional payments already made. It does not establish that an insurer remains responsible for medical expenses incurred after a settlement that releases future liability.

2) FCA pleading/standards invoked, but not dispositive

• United States ex rel. Lesinksi v. S. Fla. Water Mgmt. Dist., 739 F.3d 598 (11th Cir. 2014): Supplies de novo review for dismissal.
• United States ex rel. Clausen v. Lab'y Corp. of Am., 290 F.3d 1301 (11th Cir. 2002): Confirms Rule 9(b) particularity for FCA claims. Notably, the panel resolved the FCA counts more fundamentally: absent primary-payer responsibility, the alleged “false” billing theory collapses.

3) Judge Tjoflat’s full faith and credit / issue preclusion authorities

• Stillwell v. Eagle-Kirkpatrick Mgmt. Co., Inc., No. 49A02-1708-CT-1919, 2018 WL 3321281 (Ind. Ct. App. July 6, 2018) and Stillwell v. Eagle-Kirkpatrick Management Co., Inc., No. 49D11-1110-CT-041092, 2017 WL 11603259 (Ind.Super. July 26, 2017): The Indiana decisions enforcing the settlement were framed as dispositive of the “release” question.
• Am. Steel Building Co. v. Davidson & Richardson Constr. Co., 847 F.2d 1519 (11th Cir. 1988); Underwriters Nat'l Assurance Co. v. North Carolina Life & Acci- dent & Health Ins. Guaranty Ass'n, 455 U.S. 691 (1982); Durfee v. Duke, 375 U.S. 106 (1963); Harbuck v. Marsh Block & Co., 896 F. 2d 1327 (11th Cir. 1990): These cases support giving state judgments full faith and credit once jurisdiction is established, including respect for jurisdictional determinations when fully and fairly litigated.
• Marrese v. Am. Acad. of Orthopaedic Surgeons, 470 U.S. 373 (1985): Provides the key methodology: a federal court applies the rendering state’s preclusion law under § 1738.
• Baloco v. Drummond Co., 767 F.3d 1229 (11th Cir. 2014) and Graham v. R.J. Reynolds Tobacco Co., 857 F.3d 1169 (11th Cir. 2017): Cited for general issue-preclusion framing.
• Miller v. Patel, 212 N.E.3d 639 (Ind. 2023) (quoting Nat'l Wine & Spirits, Inc. v. Ernst & Young, LLP, 976 N.E.2d 699 (Ind. 2012)) and adopting a fairness concept from Reed v. Illinois, 808 F.3d 1103 (7th Cir. 2015): Supplies Indiana’s elements of collateral estoppel and the fairness inquiry that, in Judge Tjoflat’s view, would foreclose the federal claims because the release issue was litigated and resolved in Indiana.

B. Legal Reasoning

1) The panel’s MSP reasoning: “responsibility” must match the payments at issue

The court treated the MSP private cause of action as turning on a statutory gate: the plaintiff must demonstrate that the defendant primary plan “has or had a responsibility” to pay for the medical items/services. The panel’s crucial move was temporal and transactional: responsibility must exist with respect to the same payments Medicare made—here, post-settlement services.

Penelope tried to meet the prerequisite by pointing to (i) the insurers’ pre-settlement policy obligations (including “medpay”/no-fault components) and (ii) the existence of a settlement itself. The court rejected this, holding:

• Pre-settlement contractual responsibility, stated generally, does not establish responsibility for “hypothetical and speculative” future expenses not yet incurred.
• The Indiana-enforced settlement did the opposite of what Penelope needed: it cut off the insurers’ future responsibility and placed post-settlement lien/liability risks on the Stillwells.
• Accordingly, when Medicare later paid for post-settlement care, it did not pay “in place of” a primary plan that remained responsible; therefore, there was no reimbursement duty on the insurers for those later payments.

2) Distinguishing the “settlement doesn’t erase reimbursement” cases

Penelope relied heavily on Humana Med. Plan, Inc. v. W. Heritage Ins. Co., Hadden v. United States, and 42 C.F.R. § 411.24(i)(1) (reimbursement required even if the primary payer already reimbursed the beneficiary). The court narrowed them to their common fact pattern: pre-settlement conditional payments already made by Medicare (or a Medicare Advantage plan), where the settlement demonstrates the insurer’s responsibility for those already-incurred expenses.

Because the insurers here reimbursed Medicare for pre-settlement conditional payments, the cited authorities did not support extending responsibility to post-settlement expenses incurred after a settlement release.

3) Rejecting importation of workers’ compensation settlement rules into tort settlements

Penelope argued by analogy to workers’ compensation regulations (42 C.F.R. §§ 411.40–47), especially 42 C.F.R. § 411.46(a)–(b), contending Medicare would not “recognize” a settlement that fails to protect Medicare’s interests regarding future medicals. The panel rejected the analogy on two grounds:

• Category mismatch: workers’ compensation is “fundamentally different” from tort liability; the court declined to “shoehorn” tort settlements into that framework.
• Regulatory consequence mismatch: even if applied, § 411.46(b)(2) speaks to Medicare’s prospective payment posture (“will not pay for treatment”), not a post hoc reimbursement right against insurers for future-medical payments Medicare nevertheless made.

4) Medpay/no-fault policy provisions do not survive a release

The panel also rejected reliance on “unused medpay funds” and no-fault medical-expense coverage embedded in the liability policies. The court treated the settlement-and-release (as enforced by the Indiana court) as extinguishing any further insurer responsibility under the policies for the accident—so no “primary plan” responsibility remained after settlement for post-settlement medicals.

5) FCA claims fall with the MSP predicate

Every FCA count assumed the same foundational fact: that the insurers remained primary payers for post-settlement accident-related care. Once the court concluded there was no such responsibility:

• Providers’ submissions to Medicare for post-settlement care were not “false claims” because Medicare was not improperly secondary to an existing responsible primary plan.
• There was no “reverse false claim” concealment of an obligation to pay the government because no obligation existed for post-settlement expenses.
• Conspiracy counts failed as derivative of the non-existent underlying fraud.

Penelope’s additional theory—that insurers failed to report the settlement to Medicare—failed factually (Medicare’s letter reflected notice) and legally (even without notice, no insurer responsibility meant no falsity).

6) The concurrence’s alternative ground: preclusion by Indiana’s settlement enforcement judgment

Judge Tjoflat’s concurrence reframed the case as beginning (and ending) with the settlement enforcement proceedings in Indiana. Under 28 U.S.C. § 1738, the federal court must give the Indiana judgment the same preclusive effect it would have in Indiana courts. Applying Indiana collateral estoppel principles (as synthesized in Miller v. Patel and Nat'l Wine & Spirits, Inc. v. Ernst & Young, LLP), Judge Tjoflat concluded:

• The Indiana courts finally adjudicated enforceability and scope of the settlement release (including future medicals/lien allocation).
• The Stillwells had a full and fair opportunity to litigate any fraud/invalidity contention in those proceedings.
• Therefore, the federal claims—premised on avoiding the release’s consequences—were foreclosed by issue preclusion.

C. Impact

1) Tort settlements: a clearer line between pre- and post-settlement Medicare issues

The decision reinforces a practical boundary:

• Pre-settlement conditional payments: liability settlements often demonstrate responsibility for already-incurred expenses, triggering reimbursement duties (the Humana/Hadden
• Post-settlement future medicals: where a settlement and release (especially one judicially enforced) allocates future medical/lien responsibility to the claimant, MSP “responsibility” for later-incurred services does not persist against the liability insurers absent some independent legal basis establishing that responsibility at the time of Medicare’s later payments.

2) FCA as an MSP backdoor: limited when “primary payer” status is absent

The opinion signals skepticism toward FCA theories that attempt to convert MSP reimbursement disputes into fraud cases without a concrete, existing primary-plan responsibility for the specific services at issue. If Medicare is appropriately primary post-settlement, billing Medicare is not false, and “reverse false claims” theories lack an “obligation” to anchor them.

3) Workers’ compensation analogies: likely to be resisted in tort contexts

By refusing to import the 42 C.F.R. § 411.46 framework, the panel reduces the likelihood that courts in this circuit will use workers’ compensation “future medical” rules (often associated with MSAs in practice) to impose similar requirements on tort-liability settlements via regulation-by-analogy.

4) Preclusion consequences for post-settlement federal litigation

The concurrence highlights a recurring litigation hazard: once a state court enforces a settlement allocating future medical lien obligations, federal MSP/FCA claims designed to reallocate that burden may be barred by full faith and credit and state issue preclusion doctrines.

4. Complex Concepts Simplified

• “Primary payer” (MSP): An insurer (or plan) that should pay before Medicare for certain medical expenses.
• “Conditional payment”: Medicare pays first only because the primary payer has not paid (or cannot be expected to pay promptly). Medicare’s payment is “conditioned” on being reimbursed later if a primary payer’s responsibility is shown.
• “Responsibility” under 42 U.S.C. § 1395y(b)(2)(B)(ii): A demonstrated legal duty of the primary plan to pay for the specific medical items/services—often shown by a judgment or settlement. This case emphasizes that responsibility must align with the timing/identity of the payments Medicare made (here, post-settlement services).
• MSP private cause of action (double damages): A tool Congress created to encourage private enforcement when a primary plan fails to pay or reimburse Medicare. But it is available only if the responsibility prerequisite is met.
• False Claims Act (FCA): Targets fraud against the government (false claims, false statements, concealment of an obligation to pay, conspiracies). If Medicare was properly billed because no primary payer was responsible, the “fraud” predicate is missing.
• Full faith and credit / 28 U.S.C. § 1738: Federal courts must respect state court judgments as state courts would, including giving them preclusive effect where applicable.
• Collateral estoppel (issue preclusion): Once an issue is actually litigated and necessarily decided in a prior case, it cannot be relitigated later between the parties (subject to fairness limits under state law).

5. Conclusion

The Eleventh Circuit affirmed dismissal because the Indiana-enforced settlement and release eliminated the insurers’ post-settlement responsibility for accident-related medical expenses, which in turn eliminated any duty to reimburse Medicare for Medicare’s post-settlement payments. Without that MSP predicate, the MSP private cause of action could not proceed, and the FCA counts—each premised on continued primary-payer responsibility—necessarily failed. Judge Tjoflat’s concurrence underscores an additional, potent barrier: state-court settlement enforcement judgments may preclude later federal MSP/FCA litigation under full faith and credit and state issue-preclusion doctrine.
