Surprise Billing

Surprise Billing is an unexpected and often exorbitant medical bill a patient receives after receiving care from an out-of-network healthcare provider, typically without their prior knowledge or consent. Imagine you go to an in-network hospital for a planned surgery. You've done your homework, confirming the hospital and your surgeon are covered by your insurance. Weeks later, a massive bill arrives from the anesthesiologist or a consulting radiologist—someone you may not have even met—who, unbeknownst to you, was not part of your insurance network. Your insurer pays a fraction of their inflated charge, and the provider then bills you for the remaining, often staggering, amount. This practice of billing the patient for the difference between the provider's charge and the insurer's payment is known as balance billing. This financial ambush was a significant problem, particularly in the United States, turning medical emergencies into financial catastrophes for many families.

While it sounds purely like a consumer healthcare nightmare, surprise billing was also a multi-billion dollar business model—and a major red flag for savvy investors. For years, certain segments of the healthcare industry, particularly physician staffing firms and some hospital departments, built lucrative strategies around this practice. Understanding this dynamic is a masterclass in identifying regulatory risk and questioning the quality of a company's earnings. A business model built on angering customers and exploiting system loopholes is inherently unstable, making it a poor foundation for a long-term investment.

The investment thesis for some healthcare service companies was directly tied to their ability to levy out-of-network charges.

• Private Equity and Staffing Firms: The rise of surprise billing was closely linked to the consolidation of physician practices (like anesthesiology, emergency medicine, and radiology) by firms often owned by private equity. A common strategy was to pull these physician groups out of insurance networks. This gave them the leverage to bill at much higher rates than negotiated in-network prices, generating massive cash flow. For an investor, these revenue streams looked fantastic on paper but were built on a foundation of sand.
• Insurers and Hospitals: Insurance companies were caught between angry customers and high-cost providers. While they technically saved money in the short term by paying lower in-network equivalent rates for these services, the practice fueled healthcare inflation and immense reputational damage. Hospitals also faced backlash, as patients blamed the entire institution for bills originating from third-party doctors working within their walls.

Predictably, a practice so unpopular with the public eventually attracts government intervention. In the United States, the federal government passed the No Surprises Act, which took effect in 2022. This landmark legislation fundamentally changed the landscape by:

• Protecting Patients: It largely bans surprise billing for emergency services and for out-of-network care at in-network facilities. Patients are now typically only responsible for their normal in-network cost-sharing amounts (like deductibles and co-pays).
• Forcing Negotiation: Instead of billing the patient, the out-of-network provider and the insurer must now work it out themselves, usually through a negotiation and arbitration process.

The law effectively dismantled the business model of profiting from out-of-network surprise bills, causing a significant shock to the valuations and future prospects of the companies that had relied on it.

For value investors, the story of surprise billing offers timeless lessons about looking beyond the spreadsheet and analyzing the sustainability of a business.

• Quality Over Quantity: Not all earnings are created equal. Profits derived from consumer-unfriendly, ethically questionable, or legally grey practices are low-quality. They are prone to disappearing overnight due to public outcry or new legislation. A core part of due diligence is asking: How does this company make its money? Is it creating value or just exploiting a loophole?
• Spotting Regulatory Risk: A business model that seems too good to be true often is. If a company's success depends on a lack of regulation or consumer ignorance, it carries immense regulatory risk. Astute investors saw the political tide turning against surprise billing years before legislation was passed and correctly identified the companies most vulnerable.
• The Moat That Wasn't: A true competitive moat is a durable advantage, like a beloved brand, a low-cost structure, or a network effect. The ability to send surprise bills was never a moat; it was a temporary privilege based on a market failure. When the rules changed, the “advantage” vanished, proving it was never a source of lasting value.
