MultiPlan Out-of-Network Underpayment Litigation (MDL 3121)
Healthcare providers across the country are discovering they may have been underpaid for years—possibly without ever knowing why. The problem centers on MultiPlan, Inc., (recently renamed as Claritev) a powerful insurance company and claim pricing company working in tandem with some of the nation’s largest health insurers. Together, they are accused of deploying a scheme to suppress out-of-network (OON) reimbursements using an algorithm called Data iSight and Vivant
This alleged scheme is now the subject of Multi-District Litigation (MDL 3121) in federal court. Healthcare professionals assert that MultiPlan’s algorithm, combined with coordinated insurer participation, unfairly lowered payments for OON claims—causing billions in financial damage to emergency departments, specialty clinics, ambulatory surgery centers, behavioral health providers, chiropractic practices, and other medical professionals nationwide.
If your practice accepted out-of-network insurance and received payments processed through MultiPlan or its repricing products Data I-Sight and Vivant, you may have been systematically underpaid. You may now be entitled to financial compensation through the ongoing federal litigation.
Rafferty Domnick Cunningham & Yaffa is committed to helping health care professionals understand the value of their underpaid claims, determine whether they are eligible to join the litigation, and pursue meaningful recovery for years of lost revenue.
What Is MDL 3121?
The federal lawsuit titled In re MultiPlan Health Insurance Provider Litigation (MDL No. 3121, Case No. 1:24-cv-06795, Northern District of Illinois) brings together claims from healthcare providers around the country. These claims allege that MultiPlan and its insurer partners engaged in anticompetitive conduct and unlawful price-fixing to lower provider reimbursements for OON medical services.
The litigation accuses MultiPlan and multiple insurers of violating:
- The Sherman Antitrust Act
- Various state-level antitrust statutes
- State consumer protection laws
In 2024, the federal court overseeing the case allowed these claims to proceed, confirming that the providers involved have legal standing to pursue financial compensation. This means that the court recognized there is a valid legal basis for the allegations and that affected healthcare professionals may have a right to recover the damages they suffered.
The first bellwether trial in MDL 3121 is currently scheduled for December 7, 2027, representing a pivotal opportunity for impacted providers to seek long-overdue justice.
This litigation has the potential to set a national precedent in how out-of-network services are reimbursed and how provider compensation is determined.
How MultiPlan’s Alleged Reimbursement Scheme Operated
Central to the litigation is the use of MultiPlan’s Data iSight platform, which providers allege was designed to systematically reduce reimbursement rates across the entire OON landscape.
According to the complaint, insurers delegated pricing authority to MultiPlan and allowed it to generate reduced “target prices” that were far below market value. These prices were then applied uniformly to provider claims—without individualized evaluation or reference to usual and customary rates.
The legal allegations include the following key strategies:
1. Algorithm-Based Price Suppression
The Data iSight algorithm allegedly calculated target reimbursement rates intended to reduce payments as much as possible, regardless of service type, regional norms, or provider specialty. These “benchmarked” prices were not independently verified and were significantly below what the medical services would command in a fair and open market.
2. Collusion and Coordination Among Insurers
Rather than assessing provider claims independently, insurers allegedly relied on MultiPlan’s standardized pricing. This created a uniform reimbursement structure across companies that would typically be competitors, turning what should have been market competition into a form of centralized price control.
3. Coercive Negotiation Tactics
Providers were often given a choice: accept MultiPlan’s reduced rate or risk receiving even lower payment on future claims. Many practices were told they would face reimbursement delays or complete denials if they refused the proposed rate. These one-sided tactics left providers without leverage and in many cases, without recourse.
4. Prohibition of Balance Billing
In many situations, the insurers prohibited providers from billing patients for the unpaid balance—the difference between what was billed and what was paid. This left practices to absorb the financial shortfall, even when the patient received necessary and life-saving care.
5. Nationwide Reach and Scale
By 2020, MultiPlan processed more than 370,000 claims per day, and its algorithmic pricing model was applied to more than 80 percent of all out-of-network claims in the United States. The result was a seismic financial impact on providers. In one quarter of 2024 alone, MultiPlan allegedly facilitated $6.4 billion in suppressed provider payments, with over $19 billion in estimated underpayments across a single year.
This is not a localized issue or a billing error. It is an alleged systemic, nationwide underpayment strategy that may have harmed thousands of practices over multiple years.
Who May Qualify to Join the MultiPlan Litigation?
Any medical professional or organization that accepted out-of-network patients and received reimbursements processed by MultiPlan may have been financially harmed. Rafferty Domnick Cunningham & Yaffa can help you determine whether your claims qualify for inclusion in MDL 3121.
Certain provider types are especially likely to have experienced underpayment due to the structure of their services and their dependence on OON reimbursement.
Emergency Medicine Providers
Emergency departments and hospital-based physicians are legally required to treat all patients, regardless of insurance status. This exposes them to significant financial risk when OON claims are underpaid.
Ambulatory Surgery Centers (ASCs)
ASCs often operate in a non-hospital setting, treating patients with private or employer-sponsored health plans. Many of these facilities have limited ability to negotiate favorable OON contracts, making them highly susceptible to pricing suppression by MultiPlan.
Behavioral Health and Addiction Treatment Providers
This sector is often excluded from narrow insurance networks, meaning providers routinely treat OON patients. As a result, they are more dependent on fair OON reimbursements and more vulnerable to manipulation of payment rates.
Specialty Practices Receiving OON Payments
These include anesthesiology, orthopedics, radiology, chiropractic care, pain management, and other specialized outpatient clinics. Many of these providers work on a referral or case-by-case basis and are routinely impacted by insurer-controlled reimbursement schedules.
If your practice consistently received OON payments that fell far below the billed amount—and those payments were processed through MultiPlan or associated insurers—your practice may be eligible to join the litigation.
Why the MultiPlan Lawsuit Matters
The MultiPlan MDL is more than a financial recovery opportunity. It is a direct legal challenge to a system that, for years, has undermined providers’ ability to deliver care and operate sustainable practices.
Joining the lawsuit may allow your practice to:
Recover Financial Losses
Practices may be able to recover the difference between what they were paid and what they should have been paid based on market standards. This could total hundreds of thousands—or even millions—depending on claim volume and specialty.
Hold Insurers and Pricing Platforms Accountable
This is a rare opportunity to confront large-scale, coordinated pricing practices that have damaged independent providers for years. A successful outcome could shift how insurers approach OON reimbursements in the future.
Restore Financial Stability
Many providers have absorbed steep losses without realizing they were the result of a suppressed pricing scheme. Financial recovery can help restore staffing, reinvest in patient services, expand capacity, or simply stabilize operations.
Protect Access to Care
When providers are not reimbursed fairly, entire communities suffer. Joining this litigation helps ensure that OON providers remain viable and available to patients—especially in emergency and specialized care settings.

Frequently Asked Questions (FAQ)
What is the MultiPlan MDL about?
The MultiPlan MDL (Multi-District Litigation No. 3121) consolidates lawsuits from healthcare providers across the United States who allege that MultiPlan, in coordination with major insurers, suppressed out-of-network (OON) reimbursement rates using an algorithm called Data iSight. The lawsuit claims this system allowed insurers to pay significantly below fair-market value for medically necessary services, resulting in widespread underpayment to providers.
Who is eligible to join the MultiPlan litigation?
Any healthcare provider or medical practice that received OON payments processed through MultiPlan may be eligible. This includes emergency medicine groups, ambulatory surgery centers (ASCs), behavioral health clinics, radiology practices, anesthesiologists, pain management providers, and other specialty practices. If you received OON payments that were lower than expected—especially where MultiPlan or Data iSight was mentioned—your practice may qualify.
How do I know if my claims were processed by MultiPlan or Data iSight?
MultiPlan and its algorithm, Data iSight, are often referenced in explanation of benefits (EOBs), payment remittance notices, or correspondence from insurers. If your claims were paid at unexpectedly low rates with references to MultiPlan, “repricing,” or “target pricing,” that’s a strong indicator. Our legal team can help you review your payment records to determine whether your claims were subject to MultiPlan pricing.
What types of claims are eligible for recovery?
The litigation targets underpaid out-of-network claims, especially those processed using MultiPlan’s pricing tools. Claims that were priced significantly below the usual, customary, and reasonable (UCR) rates—and where balance billing was restricted—may qualify. These can include emergency services, outpatient procedures, diagnostic imaging, surgical interventions, behavioral health treatment, and more.
Is this a class action lawsuit?
This is a multi-district litigation (MDL), not a traditional class action. While similar claims are consolidated into one federal court to streamline pretrial proceedings, each provider’s case is still evaluated individually. This means your claim will be assessed based on the specific facts, services rendered, payment history, and damages your practice suffered.
