When Congress passed the No Surprises Act in 2020, the goal sounded straightforward enough. Stop hammering patients with massive out-of-network medical bills when they get rushed to the emergency room or undergo surgery with an unexpected out-of-network provider.
It worked for patients. You don't get stuck with a $50,000 bill from an out-of-network anesthesiologist anymore. But behind closed doors, the law created a lucrative windfall for medical practices, private equity firms, and dispute resolution arbitrators.
Federal data released by the Centers for Medicare & Medicaid Services shows doctor payouts through the federal arbitration system surged to $14 billion in 2025. That's up from $4 billion in 2024. Total case filings jumped from 1.4 million to 2.5 million in a single year. Officials at CMS now openly admit the arbitration system is getting gamed to push prices sky-high.
Here is what's really going on inside the medical billing war, who's making money, and what it means for your healthcare premiums.
The Loophole in Federal Arbitration
Patients are shielded from surprise medical bills, but the underlying money didn't disappear. It shifted to a federal process called Independent Dispute Resolution.
When an out-of-network doctor treats a patient, the health insurance company sends an initial reimbursement payment. If the doctor thinks the payout is too low, they don't bill the patient anymore. Instead, they drag the health insurer into baseball-style arbitration.
In this system, both parties submit a final dollar figure. A certified third-party arbitrator picks one offer. No middle ground. No compromise.
It turns out doctors win these arbitration disputes over 85 percent of the time.
Federal Dispute Resolution Growth (2024 vs 2025)
Case Volume:
2024: 1.4 million cases
2025: 2.5 million cases
Total Doctor Payouts:
2024: $4 billion
2025: $14 billion
Arbitrator Earnings:
2024: $559 million
2025: $1.3 billion
Doctors aren't just winning. They're securing payouts four to six times higher than standard in-network contract rates.
Investigations into federal arbitration records revealed startling cases. A plastic surgeon collected $440,000 for a single breast reduction surgery. An assistant surgeon bagged $196,566 for helping with a scoliosis procedure. In another case, an arbitrator handed a practice $333,000 after an insurer initially paid far less.
Even routine procedures are getting swept into this system. Gynecologists have won arbitration awards up to 600 times standard rates for placing intrauterine contraceptive devices. Specialty groups in spinal surgery and plastic surgery—fields where surprise billing was historically rare—now routinely file thousands of arbitration claims.
Why the System Incentivizes Higher Claims
Why are providers winning almost every single time?
The original law was meant to use median in-network rates as a baseline for fair payment. However, early legal challenges brought by physician lobbying groups, including the Texas Medical Association, successfully struck down rules that instructed arbitrators to prioritize those baseline rates.
With that guardrail gone, arbitrators began accepting provider arguments based on billed charges—the artificially inflated "sticker prices" that medical facilities rarely collect in normal negotiations.
At the same time, the third-party arbitration entities deciding these cases operate on a fee-for-service model. Arbitrators collect fees ranging from $425 to $1,150 per case, paid by the participating parties. In 2025 alone, arbitration firms pulled in $1.3 billion in fees, up from $559 million in 2024. Critics point out a obvious incentive flaw. When arbiters make millions processing claims, there is little motivation to reject questionable submissions or slow down the gravy train.
Third-party billing firms and venture-backed management companies quickly noticed the math. They built automated software engines designed to flood the federal portal with hundreds of thousands of claims, bundling procedures together to maximize arbitration yields.
How Ineligible Claims Clog Federal Portals
The surge in claims overwhelmed the federal dispute portal. Regulators originally estimated around 17,000 dispute filings per year when drafting the law. Instead, the portal has logged more than 5 million claims since launching in 2022.
A huge chunk of these filings shouldn't be in arbitration at all.
Insurers estimate that up to a third of submitted disputes involve ineligible claims. That includes patients covered by Medicare or Medicaid, which are governed by separate fee schedules, or claims that never completed the mandatory 30-day open negotiation window.
Because arbiters take weeks or months to review eligibility, millions of invalid claims sit in line. That backlog ties up capital and forces health plans to hire armies of legal consultants just to manage the paperwork.
The administrative overhead alone cost the healthcare system over $2.8 billion between 2022 and 2025.
What Higher Payouts Mean for Your Monthly Premium
Patients feel safe because they don't get a huge bill in the mail after an emergency room visit. That protection is real, but the financial burden didn't go away. It just changed forms.
When insurance companies spend $14 billion resolving out-of-network claims alongside billions more in administrative fees, that cash comes out of the pool created by member premiums.
Health plans recalculate their risk every year. When emergency and specialty care costs jump unexpectedly due to arbitration payouts, insurers raise monthly premiums across the board for employer-sponsored and individual health plans.
You might not pay a $10,000 surprise bill today, but you and your employer will likely pay higher monthly insurance rates next year to cover the collective cost of those arbitration wins.
Federal Reforms and What Changes Next
Federal agencies are finally pushing back. The Department of Health and Human Services, along with the Labor and Treasury Departments, finalized operational reforms aimed at fixing the arbitration bottleneck and curbing abuse.
Key changes rolling out across the federal dispute system include:
- Slashing administrative fees: The per-party federal administrative fee drops from $115 to $15 per dispute, making the portal less costly for legitimate small claims while adjusting financial mechanics.
- Strict eligibility timelines: Certified arbiters now have a hard five-day deadline to verify whether a claim is legally eligible for arbitration before moving forward.
- Standardized communication codes: Insurers must use uniform claim adjustment codes when making initial payments or denials, eliminating confusion over why a claim was paid at a specific rate.
- Expanded claim batching: Providers can combine up to 50 related items or services into a single dispute filing, reducing repetitive paperwork while capping batch sizes to prevent massive bloated filings.
- Centralized IDR Gateway: A single digital portal tracks disputes, enforces open negotiation windows, and verifies plan registration numbers to prevent wrong-entity filings.
While these administrative rules aim to clean up portal mechanics, the fundamental dispute over payment benchmarks remains unresolved. Lawmakers in Congress have introduced measures like the No Surprises Act Enforcement Act to tighten oversight, but physician groups continue to fight in court to protect their arbitration returns.
What You Should Do as a Patient
Even with the arbitration chaos happening behind the scenes, your rights under the No Surprises Act remain intact.
- Know your rights for emergency care: If you go to an emergency room, you cannot be balance-billed for out-of-network emergency services, regardless of who treats you.
- Check elective facility coverage: If you schedule a elective procedure at an in-network hospital or surgery center, out-of-network doctors (like anesthesiologists or radiologists) operating at that facility cannot bill you extra unless you signed a specific, voluntary consent form in advance.
- Review your Explanation of Benefits: If you receive a bill directly from a doctor or facility that exceeds your normal co-pay or deductible for emergency care, do not pay it immediately. Contact your insurer and cite the No Surprises Act.
- Report violations: If a provider attempts to collect an illegal balance bill, file a complaint directly through the official CMS No Surprises Help Desk at 1-800-985-3059.
