$556M
Kaiser Permanente Affiliates — MA Risk-Adjustment Settlement
The largest MA risk-adjustment FCA recovery on record. Kaiser allegedly mined past medical history to add unsupported diagnosis codes via provider queries and addenda — with quotas and no symmetric deletion of unsupported codes. $95M relator share.
Up to $98M
Independent Health — MA Risk-Adjustment Settlement
Independent Health stood up wholly-owned subsidiary DxID to conduct retrospective chart review and "nudge" providers to file addenda. Settlement capped at $98M (ability-to-pay structure), plus a five-year CIA and personal liability for the DxID CEO.
$62.85M
Seoul Medical Group — MA Risk-Adjustment Settlement
SMG submitted fabricated diagnoses for two high-risk-score spinal conditions, declined the audit subsidiary's correction recommendation, then acquired and terminated it. Engaged a radiology co-conspirator to generate supporting reports. $1.76M CEO personal liability.
$1.3B
Esformes Skilled-Nursing Kickback Scheme
Cash bribes to physicians and patient recruiters drove a 20-year sentence and the largest individual healthcare-fraud penalty on record.
$623M
Olympus Corporation of the Americas
Free equipment, training, and foreign travel offered to hospitals and physicians as inducements for medical-device purchases.
$513M
Tenet Healthcare / HMA Settlement
Fabricated FMV opinions and above-market consulting fees converted referral relationships into $513M of tainted Medicaid claims.
$345M
Community Health Network — Stark Law Settlement
Largest Stark FCA settlement at announcement. CHN fed valuation firms false compensation inputs, then ignored the "staggering"-and-"high" warnings that came back anyway. Volume-tied bonuses on recruited cardiology, cardiothoracic, vascular, neurosurgery, and breast specialists.
$85M
Halifax Health Medical Director Settlement
Six oncology medical-directorship agreements paid bonuses tied to referral volume, breaching Stark's prohibition on volume-based compensation.
$72.4M
United States v. Tuomey Healthcare System
Part-time employment agreements with 19 specialists effectively compensated them for referrals; the largest Stark FCA verdict at the time.
$69.5M
North Broward Hospital District
Nine employed physicians' compensation systematically exceeded their personally-collected revenue, signaling pay tied to referral volume.
$65M
Prime Healthcare ER Admit Scheme
Emergency-department medical directors received bonuses tied to admission rates, creating a financial incentive to admit rather than treat-and-release.
$50M
Wheeling Hospital Cardiology Division
Compensation paid to high-referring cardiologists materially exceeded contemporaneous market benchmarks without supporting FMV opinions.
$38M
UPMC Neurosurgery — Stark Law Settlement
A 12-year qui tam carried by the relator bar alone. Third Circuit's Bookwalter ruling clarified that productivity-labeled bonuses fail Stark Law when total compensation correlates with referral volume regardless of formula label. $11M relator share across three relators.
$31.5M
Fresno Community Health + PNA — AKS/Stark Settlement
A custom-built "HQ2" wine-and-cigar lounge for referring physicians, EHR subsidies that exceeded the safe-harbor exception, and sham "clinical integration" bonuses. PNA dissolved; CHS entered a 5-year CIA. ~$5M relator share to former PNA Controller.
$28M
Methodist Hospital Memphis
Clinical space leased to a referring oncology group at below-FMV rates, structured to reward referral volume rather than space-cost reimbursement.
$22M
St. Joseph Medical Center Bonuses
Cardiology medical-directorship contracts paid bonuses based on the number of patient admissions referred by the directors.
$14.25M
Mercy Health — Self-Disclosed Stark Settlement
First case in the cohort to demonstrate the HHS-OIG Self-Disclosure Protocol. Internal audit surfaced compensation arrangements with 1 oncologist + 5 internal medicine physicians outside FMV bounds. Settled 6 months before the Bon Secours merger closed — M&A diligence timing implication.
$9.89M
Memorial Health University Medical Center (Savannah)
Former CEO Phillip Schaengold was the qui tam relator — highest-trust whistleblower posture possible. Board-knowledge theory: board minutes and correspondence became enforcement evidence. The "paying physicians at a loss" contribution-margin theory that later informed CHN and Bookwalter prosecution.
